Everything possible on Thursday

Aside from 80° sunshine that is.

A very dynamic weather system will start and end with wintry precipitation, sandwiched with an inch or so of heavy rain! Let’s take this in batches.

1Tonight: Rain and thunder will develop after midnight, possibly mixed with snow and sleet at times. Minor snow and sleet accumulations are possible, especially along and north of US20. Our Futuretrack computer model puts down 1-2 inches of snowfall, just in time for Friday morning’s commute. Areas most likely to receive the snow accumulation are in the Freeport-Rockford corridor, points northward into Monroe, Beloit, and Janesville. Areas along the I-88 corridor will likely stay as all liquid. Temperatures will hover right at 32 degrees.

3Thursday: Morning wintry mix will become all rain by 8am as warmer air moves in from the south. Rain will be accompanied by thunder at times. Small hail and gusty wind are possible in and around thunderstorms. Highs around 47 in Rockford with 50s south of I-88. 1-2 inches of rain is likely which will cause some flooding problems. Watch for standing water on roadways and if you live near a creek, watch for rapid rises. The rivers will need to be monitored, especially on Friday and Saturday as ice jams will be possible.

4Thursday night: Very Windy with rain changing to snow. Some minor accumulations will be possible. Again, in the 1-2 inch range for Northern Illinois. However, this minor snow will come with major wind! Wind gusts will exceed 50mph in open areas causing white-out conditions. It’s conceivable that we hit all-out blizzard conditions Thursday evening after 8pm. Temperatures will fall to around 22 with wind chills around 10 degrees.

Friday: Light snow in the morning, becoming sunny and very windy. Highs around 32 with peak wind gusts around 45mph.

Midwest Mix-Up

TIMINGTonight into tomorrow is going to be an interesting time across the Stateline. Within an 18 hour time frame we could be dealing with the following: snow, rain, freezing rain, thunderstorms, strong wind, dense fog and flooding. Here is a look at the most likely scenario heading into tonight. It is important to note that temperatures will be within a degree or two on either side of 32°, so any slight shift in this system could drastically impact the time frame and amounts of each precip type.

Late tonight a strong area of low pressure will begin to track into our area with temperatures a few degrees shy of 32°. The initial precip will likely be mixed with snow, freezing rain and rain. The best chance for snow and freezing rain will be in far Northern Illinois near the Wisconsin border, and Southern Wisconsin. A few inches of snowfall accumulation early tomorrow morning is in the cards, but any new accumulation will quickly melt heading into the afternoon.

Mid-morning brings us a transition to mainly rain, some of which could be heavy at times, with a few embedded thunderstorms not out of the question. During the time frame of late morning into early afternoon we could see a brief lull in activity with a resurgence of rain for the rest of the afternoon, again with thunderstorm potential. Throughout this process, temperatures will climb well above freezing into the low 40s. Dense fog and localized flooding in low areas due to snow melt is likely.

The evening hours will kick up the wind as the back side of the system slides in and brings with it a shot of colder air and the potential for a few additional inches of snowfall.

Again, I stress that the smallest shift in storm track could greatly increase or decrease snowfall potential and accumulation especially heading into tomorrow morning. Stay tuned for more updates! – Greg

Blizzard Conditions Overnight

A Blizzard Warning is in effect for Carroll, Jo Daviess, Stephenson & Whiteside County overnight. Winter Storm Warnings are in effect for the rest of our area.  We will all deal with blizzard-like conditions through early Monday morning.  The worst of it will occur now through about 3am.

Winter Weather Alerts: Blizzard conditions area-wide

Winter Weather Alerts: Blizzard conditions area-wide

Winds have become increasingly stronger throughout the evening.  West northwest winds will be sustained between 25 and 35mph with wind gusts approaching 50mph.  Blowing and drifting with whiteout conditions are likely area-wide, with the worst being on rural roads and in open areas.

Avoid Travel Overnight

Avoid Travel Overnight

Avoid travel overnight. Numerous roads are shut down. Many cars are in ditches. Temperatures will fall below zero after midnight and wind chills will plummet to 30 below by sunrise; you do not want to be stranded in these conditions.

Snow, Wind & Cold

Another round of snow will blanket the Stateline after midnight. The bulk of the accumulating snow will occur between 2AM and 8AM Sunday morning.  Roads will quickly deteriorate shortly after the snow begins; snow could be heavy at times with reduced visibility.  Totals will generally range from 2 to 4 inches, with perhaps a bit more in isolated spots.

Headlines

Headlines

Steady snow early Sunday morning will transition to scattered light snow showers for Sunday afternoon and evening.  A cold front will blast through late Sunday afternoon or early evening, setting the stage for gusty wind (up to 40mph), bitterly cold temperatures, and life-threatening wind chills.  Near-blizzard conditions are expected for Sunday night and Monday morning making for treacherous travel.

Snowfall Through Noon Sunday

FutureTrack Snowfall Through Noon Sunday

Then comes the frostbite weather.  Temperatures will fall below zero by Monday morning and stay there through Wednesday morning. Wind chill values will be dangerously cold…..30 to 40 below zero at times.
