Monday late night update

Just talked to my brother on the southwest side of Chicago..... Silver-dollar sized flakes and snowing at the rate of 1 to 2 inches / hr !!! He says it's so bright out it looks like the middle of the day.

That's gotta be one of my favorite things that happens when you get a big snowstorm at night - how bright it is in the middle of the night !!

Well, we are on the warm air side of the storm.... bottom line, another storm taking just about the same track they all have so far this winter season - right up through the lower Ohio Valley into the Northeast... That's why the Great Lakes have gotten absolutely hammered with snowfall so far this year.

Sfc low pressure will continue to track through the area overnight. Occasional showers will also continue but gradually diminish to some spotty drizzle by morning Tuesday.











No problems on the roadways overnight through much of tomorrow as temperatures will stay above the 32 degree mark. Strong CAA will take hold during the day into Tuesday night. H85 temps progged to drop from -14 to -17C and saturated as well Tuesday night into Wednesday. In addition, a strong secondary vort max will be tracking southeast on the backside of the upper trough that will be located over the region. As this energy shifts through the region, some of the remaining moisture over the area will get squeezed out in the form of light snow and flurries. May see flurries and patchy light snow as early as Tuesday afternoon, but it should not accumulate that much with sfc temps above 32 degrees. Our LIGHT accumulations will come Tuesday night as temperatures drop below freezing.






























Certainly not a lot of snowfall is expected but a light coating is likely in many areas -generally a dusting to around an inch across just about all of the region Tuesday night into Wednesday morning.

Cold temperatures will blow into the region on gusty northwest winds. Temps easily dropping into the lower 20s Tuesday night coupled with the light snow showers and flurries could make for some icy spots overnight Tuesday and Wednesday morning.

Temperatures will slowly recover to the mid/upper 20s on Wednesday, but that should be about it.



Stay warm and have a great Tuesday



Later:

Jay
