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!

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.
