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.

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.

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.
