Snow and Fog

It took more than three months, but the Mississippi and Illinois Valleys experienced the second biggest snow of the season Sunday night and Monday.

Snowfall amounts, as of 7 a.m. Monday, ranged from around 2-6″ and when all is said and done, the final totals will be around 3-7″.

Snow Overnight

As is always the case, there could be an isolated higher total.

The snow will wind down later today and end by early tonight.

Sunshine returns Tuesday and Wednesday, but it turns rather cold.

By Wednesday morning, we’ll be waking up to lows in the single digits.

Warmer weather is on the way later this week and this weekend with 40s and 50s.

Biggest Snow Since Early December

ORIGINAL POST:  Sunday, March 12, 2017, 4:34 p.m.

As of late Sunday afternoon, light snow is falling across central Iowa.

Afternoon Snow.jpg

Snow will spread into eastern Iowa this evening and into the Quad Cities and across the Mississippi River by 8-10 p.m.

The heaviest of the snow will fall late tonight and early  Monday.

I’m still good with my morning snow total forecast.  Some locations may be off by an inch or so.  But, if we get into that ballpark range, I’m good with the prediction.

Sunday Snotals Update

Much colder air will move in with the freshly fallen snow.  Lows by Wednesday morning could drop into the single digits!

Warmer weather returns by the weekend.

I’ll see you bright and early Monday on “Local 4 News This Morning” from 5-7 a.m. with the latest on the winter storm.

Moderate to heavy snow is on the way to eastern Iowa and northern Illinois later Sunday into Monday.

A “Winter Weather Advisory” goes into effect Sunday evening and will run through Monday evening.

WWA.jpg

The storm system that’ll bring us the snow is located over Montana early Sunday.  This clipper will quickly race southeastward to south-central Iowa by Monday morning and to near St. Louis, Missouri, by midday Monday.

Since the heaviest of the snow usually falls to the north of the low pressure system, the Mississippi and Illinois Valleys are primed for the biggest snow of season since early December!

TIMING

Light snow will break out across the Midwest today and spread into eastern Iowa by late Sunday afternoon.

This snow  will reach the Quad Cities and the Mississippi River by evening.

Snowfall will become moderate overnight into early Monday morning.  There will be periods of heavy snow around daybreak Monday.

By midday Monday, the heaviest of the snow should be south of us.  However, light snow will continue into Monday evening and end Monday night.

BIGGEST SNOW SINCE EARLY DECEMBER

This storm system will be the biggest the area has seen since December 4, 2016, our first snow of the season.

That day, 10.2″ of snow fell in Davenport, Iowa, and 7.8″ accumulated in Moline, Illinois.

In the three months since then, Davenport has only picked up 8.9″ of snow and Moline saw 8.7″!

SNOWFALL AMOUNTS

Here are my forecast snotals (“snow totals”) for Sunday evening through Monday evening.

So, just find your hometown and that’s how much snow you’ll be shoveling!.

Sunday Snotals Update.jpg

Again, the heaviest of the snow will fall Sunday night and early Monday.

I’ll have another update later this afternoon and let you know if anything changes.

Major Winter Storm For Parts of Iowa

We’re down to the last week of January 2017 and we still haven’t had a measurable snow in the Quad Cities.

Our last sticking snow in the metro area was more than a month ago.  On December 17, 2016, 2.7″ of snow fell in Moline and 2.5″ accumulated in Davenport.

A winter storm moving out of the Plains today and across Iowa tomorrow will bring rain this afternoon.  This will be a wintry mix in our northern hometowns tonight and Wednesday.

rain-snow

By Wednesday afternoon, as this system moves to the Great Lakes, we’ll see a transition to all light snow for eastern Iowa and northern Illinois, especially Wednesday night.

Accumulations in our northern hometowns, around Galena, Illinois, and Maquoketa and Dubuque, Iowa, could be around an inch or two by Thursday morning.

As it looks now, the Quad Cities might see a dusting or so of snow by Thursday morning.

However, if you’re traveling to Waterloo, Iowa, 3-6″ of snow will fall there.  A “Winter Weather Advisory” goes into effect Tuesday afternoon through Wednesday evening.

warning

A “Winter Storm Warning” covers much of northern Iowa, where more than 6″ of snow will be falling.  Parts of northwestern Iowa could pick up a foot of snow!

After this storm, colder weather is on the for the rest of the week into the weekend.

Valentine’s Day Snow Storm

Happy Friday!  It’s finally here and the bright sunshine looks great out there if it wasn’t for the howling winds.

Bitterly cold temperatures are coming in tonight and when you wake up Saturday morning, lows will be around -2° in the Quad Cities and even colder to the north.

However, once you factor in the wind, most of us will have wind chills in the -15° to -25° range.

Morning sunshine Saturday will give way to cloudy skies by afternoon and light snow will break out Saturday night.

The heaviest of the snow with the storm will fall Sunday.

For several days now, I’ve been telling you that this storm would be bringing in several inches of snow and for the past two days on “Local 4 News This Morning”, I called for 3″+ of snow.

This was the timeline I gave Friday morning for the storm.

Snow Potential

Well, now that we’re just a day or so away from the start of the snow, the data is newer and the snowfall amounts can be more specific than 3″+.

After conferring with my colleague Andy McCray, we’re thinking 3-5″ of snow for much of the area late Saturday night through Sunday night.

sNOW sUNDAY

Slightly higher amounts are expected across the far north and lesser amounts across the far south.

I’m actually buying into this snow being on the “high end” of those ranges.  So, several 5″ totals are pretty realistic at this point.

It’ll be rather windy, so there’ll be a lot of blowing and drifting of snow Sunday into Monday

I’ll have another update Saturday morning to let you know if anything changes overnight. Make sure to keep up on the latest forecast.

Snow's a comin'

Except for the bitter cold, Saturday will be a great day to run errands.  That way, you can enjoy Valentine’s Day and the snow Sunday!

Heavy Snow & Wind For Much of Iowa

For a week now, I’ve been talking about a big winter storm with its sights set on the Midwest.  I’ve been telling you to keep up on the latest forecast because some parts of Iowa could be picking up some heavy snow.

Now that the storm system is near Las Vegas, Nevada, Monday morning and will move to the southern Plains this evening and then to the Great Lakes by Wednesday morning, I’m pretty confident in forecasting mainly a rain event for the Quad Cities and most of Illinois and mostly a snow event for Iowa (except for the southeastern part of the state).

We’ll see a wintry mix late tonight that’ll change over to rain for the Quad Cities and much of Illinois Tuesday. By the time it ends Tuesday night, the rain will change back to light snow. Here’s how much snow may fall.

 

As you can see, this snow will more of a driving inconvenience for the Quad Cities, southeastern Iowa, and much of Illinois, with an inch or less of snow expected.  But, we could see anywhere from one-half to one inch of rain!

Just to the northwest of the Quad Cities, 1-3″ of snow may fall around Galena, Illinois, back to Maquoketa, Iowa.  Isolated 4″ totals are possible.

However, western and central Iowa may easily pick up 3-8″ of snow with a few higher totals.  If that wasn’t bad enough, there will be a lot of wind with this storm causing blizzard conditions.

Look at the warnings out of the Des Moines National Weather Service office.

 

The red indicates a “Blizzard Warning” and the fuchsia is a “Winter Storm Warning”.  It’s going to dangerous across much of Iowa Tuesday and Tuesday night.

Once again, the Quad Cities will be missing out on the big snow this time.

It was one year ago today that we picked up 13.8″ from a snowstorm that actually started out as rain!

Heavy Snow Missing the Quad Cities

ORIGINAL POST: Sunday, January 31, 2016, 2:22 p.m.

The snowstorm that’ll bring heavy snow and blizzard-like conditions to much of western and central Iowa is now ashore out west.  It’ll be moving to the southern Plains tomorrow and then to the Great Lakes by Wednesday morning.

For most of eastern Iowa, northern Illinois, and the Quad Cities, it looks like we’ll be on the warmer side for much of the storm.

We may see some light snow or a wintry mix late Monday night that’ll change to rain for much of Tuesday.  By late Tuesday evening, we’ll be changing back over to light snow and we could get some minor accumulation.

 

You see that the low pressure system is pretty much right over the Quad Cities area and this is why we’ll see mostly rain (one-half to three-quarters of an inch), that is represented by the light and dark green.

You see a lot of dark blue across much of Iowa.  That’s the heavy snow.  6″+ of wind-blown snow is not out of the question.

As of this afternoon, much of Iowa, including Waterloo, is under a “Blizzard Watch” for late Monday evening through late Tuesday night.  This will likely be upgraded to a “Blizzard Warning” or a “Winter Storm Warning”.

Cedar Rapids, Dubuque, and Jackson County, Iowa, along with Jo Daviess County, Illinois, are under a “Winter Storm Watch” from late Monday night through late Tuesday night.

 

So, what are the chances of seeing 6″ of snow or greater? The brown over the Quad Cities show the chances at zero to 5%.

I’ll have the latest and all you need to know bright and early Monday morning on “Local 4 News this Morning” from 5-7 a.m.

Still Looking Snowy Tuesday, But…

UPDATED POST:  Saturday, January 30, 2016, 4:18 p.m.

Here’s a quick update.  I’ve really enjoyed highs today near 50° in the Quad Cities.

The big storm that we’ve been watching since it was near Japan earlier this week is now just off the Pacific coast and should move over land tomorrow.  When that happens, the amount of data we’ll have will increase drastically and so will the confidence in the winter storm forecast for Monday night and Tuesday.

The latest trend for the Quad Cities, eastern Iowa, and northern Illinois is a warmer forecast.  This would give us a wintry mix late Monday night, some rain Tuesday, and a transition to snow Tuesday evening and early Tuesday night.

This would also cut back on how much snow we’ll see.  At this time, the heaviest snow, 6″+, will fall across western and central Iowa.

Now, with that being said, that’s how it looks this evening.  This is all subject to change tomorrow once the storm comes ashore.

I’ll have another update Sunday and it’ll likely have more concrete solutions for what we’ll see Tuesday.

Enjoy the rest of your weekend.

We’re now just three days away from a big snowstorm that’ll drop some heavy snow across the Midwest.  Parts of eastern Iowa and northwestern Illinois could be getting in on some of that, too!

Before that, weekend temperatures will warm well into the 40s to around 50° Saturday and into the 40s Sunday with light rain.

Now, let’s talk snow.

Snow Saturday Morning

The storm system that’ll bring us the snow is still out in the Pacific Ocean and is expected to come ashore Sunday along the west coast.  At that time, it’ll track to the southern Plains and then make its way to the Great Lakes by Tuesday evening.

Sounds simple enough?  Yes.  But, from a weather forecasting standpoint, no.  The problem lies in what path does it take across Missouri and Illinois.

Some models have the storm farther north this morning and some have it farther south!

If the low pressure system tracks across the Quad Cities, it’ll keep the metro area and much of Illinois in the warmer air longer and cut back on snow.

If the storm tracks toward Chicago out of Missouri, we could be seeing heavier snow in eastern Iowa and a quicker transition from rain or a wintry mix to snow.

Here’s NOAA’s GFS forecast map for noon Tuesday.

Noon Tuesday GFS

So, the big question regarding heavy snow is which path out of Missouri will the low take on the way to the Great Lakes.

I’m very comfortable saying that western and central Iowa will see heavy snow, 6″ or more.

Remember the map I showed you Friday.  At this point in the game with the uncertainty, it’s still valid.

Snow Tuesday

For now, plan on much of Iowa getting a lot of snow.  As you head toward eastern Iowa and northwestern Illinois, we’re still in a holding pattern — will we see several inches or more or less?

There is a lot of moisture associated with this storm.

Moisture Tuesday

For simplicity sake, it’s all snow and we use the 10:1 rule, some places could see between 6-12″ of snow.

If the Quad Cities ends up getting on the cold side, we’ll get a big snow.  But, if we’re on the warm side, a moderate rain event with a little snow on the backside is more likely.

If the moderate to heavy snow potential wasn’t enough, there’s going to be a lot of wind with this storm causing considerable blowing and drifting snow, where the heaviest snow falls.

I’ll have another update later in the day Saturday.
