Wild temperature roller-coaster ride over the next 7 days
The big story over the next several days will be the number of temperature swings.
Winds turn southerly on Friday which will help to boost temperatures well into the 50s. The temperature surge Friday will be a brief one as a cold front will pass over the area Friday night. This will result in a shift in winds off the lake and a temperature fallback on Saturday. High temperatures Saturday will reach the mid 40s.
This cool down will also be one that will be short-lived as temperatures will climb into the 50s Sunday and into the 60s Monday (some 15-20 degrees above normal).
A cold front will approach the area late Monday that could bring showers and thunderstorms. A significant temperature downturn is to follow that will send temperatures crashing nearly 20 degrees. Tuesday and Wednesday’s high temperature will only make it into the low 40s.
Potential Thanksgiving storm
The annual Winter Awareness Week for Illinois and other Midwest states could not have come at a better time than this.
The potential for what could be an intense storm across the middle of the nation on arguably the busiest time of year for both travelers and shoppers is closely being monitored.
Numerous models have been featuring a low pressure system across the nation’s mid-section late Wednesday. Some models have tracked the storm system to move across Chicago that will keep much of the snow to the north across Wisconsin, Minnesota, and Iowa. Other models have tracked the storm system further south over the Ohio Valley that would get Chicago in on what will be our first accumulating snowfall of the season.
Either way the storm actually tracks, its looking like a big snow event for cities north of Chicago such as Madison and Green Bay. Meanwhile, a severe weather threat with the potential of damaging winds and tornadoes is in store for areas across southern Illinois, Missouri, and Arkansas.
In addition, the coldest airmass of the season is expected to arrive on Thanksgiving with temperatures struggling to make the freezing mark. Gusty winds will make it colder and could blow snow around making travel difficult.
Models predict measurable snow by December 1
Seven of the most recent 11 model runs predicts measurable snow is likely to fall within the next two weeks (between now to the start of December). Historically, 91 percent of years since 1884 have registered snowfall during this timeframe.
