Dangerous Wind Chills Tonight & Sunday

ORIGINAL POST:  Saturday, December 17, 2016, 1:12 p.m.

Good Saturday afternoon!

Two things to point out on this 1 p.m. update.

1pm

The snow is closing in on the Quad Cities.

Also, ahead of the front that’s bringing the snow, we’re around 20°.

Behind this front, it’s already 0° across northwestern Iowa and the winds chills are around -15° to -20°.

We’re still under a “Winter Weather Advisory” until midnight Saturday for about one to three inches of wind-blown snow.

Also, Saturday night and Sunday, as temperatures drop well below zero Saturday night and much of Sunday, the gusty winds will produce dangerous wind chills of -20° to -40°.

All of early Iowa and northern Illinois are under either a “Wind Chill Advisory” or a “Wind Chill Warning” from 9 p.m. Saturday through noon Sunday.

 

Brace yourself.

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.

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.

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.

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.

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.

Bitter Cold Wind Chills Today

When you walk out today, it’ll be hard to believe that just two days ago it was raining and temperatures were in the low-40s!  Even yesterday before the cold air started rushing it, we were in the mid-30s.

Today is going to be the coldest day of the winter season.

A “Wind Chill Advisory” is in effect through midday for all of Iowa and a portion of west-central Illinois. This includes the Quad Cities.

We’re starting out at 1° this morning with a wind chill of -20°.

The one-degree start ties the coldest morning this winter back on November 22, 2015.  That occurred right after the 9.9″ of snow that fell in the Quad Cities from the two-day snow event November 20th and 21st.

Snow Saturday Morning

However, back in November when we hit 1° for the low, highs the next day were back in the 40s!

That definitely won’t be the case today as many hometowns may not even reach 10° for the high.

How’s this for a silver lining:  While it’s starting very cold in the Quad Cities, it could be worse.  Early this morning, it’s -15° in Spencer, Iowa, with a wind chill of -36°.  Mason City, Iowa, is at -12° this morning with a wind chill of -35°!

For those keeping record, we officially picked up 0.2″ of snow Saturday in the Quad Cities from the snowstorm that brought 4-5″ around Bureau County, Illinois.

As for snow chances this week, a little clipper could bring an inch or so Monday and Monday night and then another shot of cold air for Tuesday.  It’ll be similar to today’s weather with highs struggling to reach 10°.

Another snow event is possible later this week.
