Dangerous Icing Tonight & Early Monday

UPDATED POST:  Sunday, January 15, 2017, 6:09 p.m.

Right now, light freezing rain is being reported from Ottumwa to Fort Madison, Iowa, to Macomb, Illinois.

In the afternoon update, all of eastern Iowa and northwestern Illinois will be under the “Winter Weather Advisory” at some point tonight into Monday.

The importance of this is that all of us will see freezing rain.  The only differences across the area will be the start and end times for the “Advisory”.  That also coincides with the timing of when the worst of the icing will be taking place.

 

With that being said, just go through this list of Iowa and Illinois counties until you find yours and that’ll let you know the hours when the worse icing will take place.

The “Winter Weather Advisory” is already underway for Des Moines, Henry, Jefferson, and Washington counties in Iowa, and for Henderson and Warren counties in Illinois.  This will expire at 9 a.m. Monday.

Knox and Stark counties in Illinois will go into the “Advisory” at 6 p.m. Sunday and this will run through noon Monday.

From midnight Sunday through noon Monday, the “Advisory” covers Cedar, Johnson, Louisa, Muscatine, and Scott counties in Iowa and Bureau, Henry, Mercer, and Rock Island in Illinois.

The “Advisory” now starts at 3 a.m. Monday through noon Monday for Clinton and Jackson counties in Iowa and for Carroll and Whiteside counties in Illinois.

It also runs from 3 a.m. to 3 p.m. Monday for Jo Daviess County, Illinois.

The start time for the “Winter Weather Advisory” (blueish-purple shading) for some of us has been pushed back again.

It still goes into effect at 3 p.m. today through noon Monday for Des Moines, Henry, Jefferson, and Washington counties in Iowa, and for Henderson and Warren counties in Illinois.

It now runs from midnight Sunday through noon Monday for Cedar, Johnson, Louisa, Muscatine, and Scott counties in Iowa and Henry, Mercer, and Rock Island in Illinois.

The highly-anticipated ice storm I’ve been talking about for over a week now will arrive later today.

The worst of the icing and hazardous driving conditions will be Sunday night and the first half of Monday.

 

Winter advisories and warnings Sunday extend from the Rockies (for heavy snow) to Iowa and Illinois (for mostly ice).

This winter storm is still located over the southwestern United States and is already bringing icy weather to the Plains early Sunday morning.

As of this posting, the heaviest icing in still across southern Missouri and Kansas. This will be moving northeast today.

If you still have errands to run or if you’re heading off to church, most of Sunday morning is still expected to be dry.

The start times for the advisories remain unchanged from my Saturday evening update.

 

A “Winter Weather Advisory” (blueish-purple shading) goes into effect at 3 p.m. today through noon Monday for Des Moines, Henry, Jefferson, and Washington counties in Iowa, and for Henderson and Warren counties in Illinois.

The “Advisory” runs from 6 p.m. today through noon Monday for Knox and Stark counties in Illinois.

And,  the “Advisory” starts at 9 p.m. Sunday and expires at noon Monday for Cedar, Clinton, Jackson, Johnson, Louisa, Muscatine, and Scott counties in Iowa and Henry, Mercer, and Rock Island in Illinois.

WINTRY MIX START TIMES

While there may patchy light snow, sleet, or freezing rain moving in late morning, I think our southern hometowns from around Fairfield and Burlington, Iowa, to Monmouth and Galesburg, Illinois, will see the more general wintry mix begin around 2-5 p.m.

The more concentrated wintry mix and icing event moves northward to the Quad Cities and along and south of Interstate 80 from around 5-8 p.m. Sunday.

It should reach northern hometowns by midnight and this may be mostly light snow there, at first.

As temperatures warm south to north Sunday night, the wintry mix will become mostly a freezing rain event.

Temperatures by late morning Monday will be rising above freezing, so rain will fall and the ice will slowly melt.  However, it may take until early afternoon for this to occur.  I wouldn’t be surprised if some of the “advisories” are extended into Monday afternoon.

ICE AMOUNTS

I’m still expectng around one-tenth of an inch of ice to accumulate for most of us.

The heaviest coating of ice, up to one-quarter of an inch, will be to the southwest of the Quad Cities.

 

One final note is that winds are not going to breezy with this storm, so even when we get a coating of ice on trees limbs and power lines, it won’t be whipping them around increasing the chances of power outages.

The bottom line is that most of Sunday morning is still expected to be dry.  You still have some time to run to the store to buy last minute groceries or supplies!

Snow's a comin'

Also, it’s always wise to have plenty of gas in your car in case you’re in an accident.  You’ll want to be able to turn the heat on, occasionally, until service crews and rescuers get to you.

I’ll monitor the start of the wintry mix and icing and update you, as needed, today.

Icing Event Begins Later Sunday

UPDATED POST:  Saturday, January 14, 2017, 3:54 p.m.

I hope everyone is having a great weekend.  Here’s my final update for the day.  I’ll have another one early Sunday.

First off, the latest models continue to slow the onset of the wintry mix Sunday.

The start time for the advisories will coincide with the start of the wintry mix of snow, sleet, and freezing rain.

A “Winter Weather Advisory” (blueish-purple shading) will go into effect Sunday into Monday for most of eastern Iowa and west-central Illinois.  This replaces the “Winter Storm Watch” that was to go into effect Sunday.

The “Advisory” will run from 3 p.m. Sunday through noon Monday for Des Moines, Henry, Jefferson, and Washington counties in Iowa, and for Henderson and Warren counties in Illinois.

For Knox and Stark counties in Illinois, the “Advisory” runs from 6 p.m. Sunday through noon Monday.

And, for the rest of the counties included in the “Advisory”, it runs from 9 p.m. Sunday through noon Monday.

Those counties are Cedar, Clinton, Jackson, Johnson, Louisa, Muscatine, and Scott counties in Iowa and Henry, Mercer, and Rock Island in Illinois.

The bottom line is the worst of the freezing rain and icing will be Sunday night through mid-morning Monday!

I’m still thinking we’ll see between one-tenth and one-quarter of an inch of ice!

Just a quick note before you read the details of Sunday’s ice storm below.  The main event and the worst of the storm will be Sunday night and early Monday.

The storm, as expected, is still showing signs of slowing down even more.

Have a great weekend and read on to be prepared.

ORIGINAL POST:  Saturday, January 14, 2017, 6:17 a.m.

The much anticipated ice storm is still coming Sunday, but it’s not likely to arrive for most of us until later in the day.

I talked about this in my Friday afternoon update and after looking at the new information this morning, I think we’ll have a few more ice-free hours Sunday.

A “Winter Storm Watch” goes into effect Sunday.

Locally, this “Watch” runs from 6 p.m. Sunday through noon Monday, except for Knox and Stark counties in Illinois.  There, the “Watch” begins at midnight Saturday and runs through 6 a.m. Monday.

At the bottom of the map you see a fuchsia and purple shading.  Those counties are under a “Freezing Rain Advisory” (fuchsia) and “Ice Storm Warning” (purple).

Later today or early Sunday morning, I expect our “Winter Storm Watch” to be changed to either a “Freezing Rain Advisory” or a “Winter Weather Advisory”.

Now, let’s talk about when this all starts and how much ice we’re expecting.

A light wintry mix may begin Sunday morning across the far south.

Hometowns from Ottumwa and Burlington, Iowa, to Galesburg, Illinois, could see a combination of snow, sleet, and freezing rain begin around midday Sunday.

For the Quad Cities and hometowns along and just south of Interstate 80, that wintry mix will start in the afternoon (4-7 p.m.).

Areas north of the metro area may see mostly snow for a while once it starts Sunday evening.

This wintry mix will transition to all freezing rain Sunday night and early Monday morning from south to north as temperatures warm overnight.

By mid-morning Monday, temperatures will be warming into the 30s and then the low-40s by afternoon, so it’ll be all rain and the ice will begin to slowly melt.

 

As you head south into those higher numbers, ice amounts could be closer to one-quarter of an inch.

Ice Ray

That’s a lot of ice!

Driving will be very hazardous Sunday night and early Monday.  Trees and power lines will have a heavy coating of ice, which could cause power outages and interruptions to cable, phone, and internet services.

While the ice might be pretty to look at, this is a very dangerous situation.

The only silver lining is that winds are not expected to be strong during this icing event at around 6-12 miles-per-hour.

I’ll have another update later Saturday.

Warmer temperatures are on the way starting Monday.  By the end of the next week, we could see highs in the 50s!

Weekend Ice Storm Threat Building

UPDATED POST:  Thursday, January 12, 2017, 3:49 p.m.

Details on the potential late weekend ice storm are still coming together.  The specifics will likely change some more as we head into the weekend.

A “Winter Storm Watch” has been issued for late Saturday night into late Sunday night for many of the counties just to the south of the Quad Cities.

Right now that includes Des Moines, Henry, Jefferson, Lee, Louisa, and Washington counties in Iowa and Henderson, Knox, Mercer, Stark, and Warren counties in Illinois.

By the time we get to the weekend, I’m thinking that this “Winter Storm Watch” will be upgraded to an “Ice Storm Warning”.  Those warnings are already in place for parts of downstate Illinois, Missouri, Kansas, and Oklahoma for the weekend.

Also, I think the Quad Cities will be included in future updates.

I still think parts of the area will see some light snow or a wintry mix Friday night, but the big event — possible significant icing — arrives late Saturday night into early Monday morning.

Be sure to join me Friday from 5-7 a.m. on “Local 4 News This Morning” for the latest information.

And, while I’m not working this weekend, you know I’ll have updates on my blog and on my Facebook page!

ORIGINAL POST:  Thursday, January 12, 2017, 5:50 a.m.

It’s been an interesting overnight and early Thursday morning with thunder and lightning, sleet, and freezing rain for hometowns south and east of the Quad Cities.

Several flashes of lightning moved through Knox County around 2-3 a.m. Thursday.

This brought a glaze of ice that coated roadways, sidewalks, and cars making for a messy morning commute.

This will move out quickly this morning and we could see some sun break through the clouds Thursday afternoon.

Our next disturbance arrives Friday night into early Saturday.  This one will bring light snow and light freezing drizzle.

For the past week or so, I’ve been telling you about a bigger storm coming late in the weekend.  That’s still on the way, but our computer models are still not agreeing on the path or timing of the storm.

With that being said, I still expect a wintry mix Sunday and Sunday night that could bring a dangerous accumulation of snow and ice.

By Monday, temperatures warm to around 42° and I’m forecasting the wintry mix early that morning to change to all rain during the day into the evening.

It’ll end as a light wintry mix Monday night or early Tuesday morning.

Since there are still many variables with this late weekend storm this far out, plan on hazardous conditions later this weekend and keep up on the latest forecast.

Temperatures next week will be rather mild for January.  Highs will warm into the low-to-mid-40s.

Winter Storm Friday & Saturday

UPDATED POST:  Thursday, December 15, 2016, 4:20 p.m. 

As the bitter cold temperatures and wind chills from Thursday morning eases, we’re getting closer to our next winter storm.

A “Winter Weather Advisory” has now been issued for Friday evening through midnight Saturday for all of the Mississippi and Illinois Valleys.

 

While there may be some light snow tonight to the west and northwest of the Quad Cities, our snow storm kicks in Friday afternoon and evening.

By Friday night, while it remains snow across our northern hometowns, the snow will mix with or change to freezing rain through Saturday morning in our southern hometowns. We’ll likely see a light accumulation of ice there.

The heaviest of the snow will come Saturday afternoon into the evening hours.  The snow will end before midnight Saturday.

Accumulations will be higher north (4″ or so).  I’m still thinking 2-4″ in the Quad Cities and along Interstate 80 with 1-2″ in our southern hometowns.

 

Join me for “Local 4 News This Morning” Friday from 5-7 a.m. for the very latest.

UPDATED POST:  Thursday, December 15, 2016, 12:44 p.m. 

A “Winter Weather Advisory” goes into effect at noon Friday and runs through 6 p.m. Saturday for Clinton and Jackson counties in Iowa and for Carroll, Jo Daviess, and Whiteside counties in Illinois.

Early projected snowfall totals and storm timing details are in the text below.

By the way, the “Wind Chill Advisory” has expired.

Anthony

ORIGINAL POST:  Thursday, December 15, 2016, early morning 

There are many weather concerns that we’ll be dealing with over the next several days.

A “Wind Chill Advisory” in effect through 10 a.m. today for much of the Mississippi and Illinois Valleys.  While temperatures will drop to around zero to -5° Thursday morning, it’ll feel more like -15° to -30°.

Our next winter storm begins to affect some of our northern and western hometowns later tonight with some light snow.  While this will cause some slick spots, accumulations will be on the low side.

The snow really kicks in Friday afternoon into Friday night and early Saturday.  There are indications that enough warm air will be pulled into this system south and east of the Quad Cities to cause the snow to change over to sleet and then freezing rain.

As you know, ice accumulations on the roadways, trees, and power lines are much worse than just snow.

Ice Ray

This wintry mix will change back over to snow Saturday afternoon.  Across our northern hometowns, this event will likely be all snow.

Now let’s talk about possible snow accumulations.

 

I advise you to keep up on the latest forecast because these numbers could change or shift north or south depending on the path of the storm and how much warm air is brought into the system.

I think the heaviest snow will be 4″ or more from around Clinton, Iowa, to Sterling, Illinois, northward.

Along Interstate 80 and in the Quad Cities, I think 2-4″ of snow will accumulate.

South of the Quad Cities from around Burlington, Iowa, to Monmouth and Galesburg, Illinois, an inch or two will fall.  This area may also see some ice accumulation.

Once this storm departs Saturday night, bitterly cold and dangerously low temperatures will return.

When you wake up Sunday and Monday mornings, lows will be about -10° in the Quad Cities and even colder to the north.  When you add in the wind, wind chills could be as low as -20° to -40°.  It only takes a short period of time outdoors for frostbite to set in.

Highs Sunday will likely stay below zero to the north and near zero in the Quad Cities.

Later next week, temperatures will rebound to the 20s and 30s.

Again, keep up on the latest forecast with this incoming winter storm.

Dangerous Temperatures & Wind Chills

Temperatures Tuesday evening dropped to below zero north of the Quad Cities before southerly winds brought in slowly rising temperatures.

Sterling, Illinois, dropped to -5°, while Davenport dropped to zero.

The coldest air of the season arrives tonight and Thursday morning.

Low temperatures will drop to below zero across all of the Mississippi and Illinois Valleys.   When the winds are factored in, it’ll feel like -20° to -30°, which is very dangerous if you have to be out for any period of time.

WCA.jpg

A “Wind Chill Advisory” goes into effect Wednesday evening through 10 a.m. Thursday.

Highs Thursday will likely stay in the single digits in our northern hometowns to around 12° in the Quad Cities and 15° in our southern hometowns.

NOW, LET’S TALK SNOW!

Light snow will break out late Thursday night into Friday morning.  The best chance of seeing light accumulations during that time period will be around the Quad Cities to the northwest.

Snow will really kick in Friday afternoon into Saturday morning.  South and east of the Quad Cities, warm air aloft could cause the snow to change to sleet and then freezing rain.

While that’ll cut back on snow accumulations there, icy conditions will make it more dangerous.

The wintry mix will change back to snow Saturday before ending by evening.

Several inches of snow are likely.  By Thursday, I’ll have a much better idea of accumulations.

It gets even colder Sunday with highs only in the single digits with a low of -10° Sunday night.  That’s the temperature and not the wind chill!

The bottom line:  Bitterly cold temperatures through early next week and a winter storm is likely this Friday and Saturday.

Anthony

Cold Blast; Then More Snow (& Ice?)

Two snowstorms into the winter season, I’m watching another system that’ll bring snow to the area Friday and Saturday.

Depending on the path of the storm, we might even see a period of freezing rain and icy weather Friday night and early Saturday.

Stay up on the latest forecast as we head toward the end of the week.

Very cold air is already settling in and even colder air is on the way later this week.

Overnight, we dropped to 9° in the Quad Cities before temperatures started rising.  This was the first time in the single digits since we hit 4° back on February 13, 2016.

The coldest air is still to come.  When we wake up Thursday morning, lows will likely drop below zero and wind chills could reach -20° to -30°.

After the winter storm Friday and Saturday, another blast of cold air arrives for Sunday.

Dangerous Ice Storm Hits Monday

UPDATED POST:  Sunday, December 27, 2015, 4:53 p.m.

Our “Winter Storm Watch” has been upgraded to a “Winter Storm Warning”.

 

Over the next 36 hours from late Sunday night through Tuesday morning, eastern Iowa and northern Illinois will see a significant amount of freezing rain, sleet, snow, and rain.

This will all break out in our southern hometowns before or around midnight Sunday and move northward to the Quad Cities overnight and head into our northern hometowns early Monday morning.

The heaviest ice accumulation will be from the Quad Cities back to southeastern Iowa, where more than one-quarter of an inch will glaze surfaces.

This is a very dangerous winter storm for us because of the heavy icing threat and winds gusting to 50 miles-per-hour, at times, which will likely bring down tree limbs and power lines causing power outages.

As temperatures drop Monday evening and Monday night, we could still pick up 1-3″ of snow around the Quad Cities (likely on the lower end of that range).  The heaviest snow nearby, 2-4, will be around Iowa City and Cedar Rapids, Iowa.

Heavy snow is in the forecast for central and western Iowa (6-12″) and heavy rains are expected across central Illinois.

Join me for the very latest beginning at 5 a.m. on “Local 4 News This Morning” Monday.

It’s the calm before the storm.

In a typical winter, I’d likely be watching the storm coming in and working to determine how much snow would blanket the area.

Since we’re in an El Nino winter and have seen a very warm December, this storm is going to be more a “wintry mix” storm and I’m working on the forecast and focusing on how much ice will accumulate and the snow amounts for eastern Iowa and northern Illinois are secondary.

While there’s still some model dependencies, this is looking to mainly be an ice storm for much of northern Illinois and eastern Iowa with some snow and for western Iowa, a heavy snow maker.

For the Mississippi and Illinois Valleys, we’re still under a “Winter Storm Watch” that begins late tonight in our southern hometowns and early Monday from the Quad Cities northward.

This runs through late Monday night.

 

This is going to be a big impact storm on a still busy travel period coming right after Christmas.  Notice that there are winter weather advisories, watches, and warnings (even a “Blizzard Warning” across Texas in the red) from the Southwestern United States through the Plains up to the Great Lakes.

After a nice day today, a wintry mix of freezing rain and sleet moves into our southern hometowns late tonight and will move northward from there arriving in the Quad Cities well before daybreak.  It’ll continue moving north Monday morning.

As temperatures hover in the low-to-mid-30s Monday, there will be periods when the wintry mix will mix with or change to rain, especially in our southern hometowns.

For the Quad Cities, we’ll see mostly freezing rain and sleet with some rain, at times, before it changes over to all light snow Monday evening and Monday night.

As for snow amounts on top of the ice accumulations, the Quad Cities will mainly see 1-3″.  Lesser snow accumulations are expected south and east with more snow off to the northwest.  Around Iowa City and Cedar Rapids, 3-6″ of snow may accumulate.  Western Iowa could see upwards to 8″ of snow with little in the way of ice.

 

We all know that just a little ice can cause major headaches and the bad news with this system is that we’ll likely see more than one-quarter of an inch of ice.  Some hometowns may see closer to one-half of an inch.

With winds blowing at 20 to 30 miles-per-hour and gusting to 40 or 50 miles-per-hour, this will easily bring down tree limbs and power lines causing power outages.

This has the potential and likelihood of becoming a DANGEROUS WINTER STORM!

After the ice and snow, more typical cold weather will dominate for the remainder of the upcoming week.

I’ll have another update later today.
