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.
