Rain, a Cooldown and (Possibly) Winter Weather Reach the Tri-State

Temperatures plunge as rainfall exits. Winter weather may even return to the Tri-State.

Posted: Dec 11, 2020 11:21 PM

After what was our warmest 48 hours in three weeks, cooler weather (along with rainfall) has returned to the Tri-State. A passing core of low pressure and associated cold front will swing through the Midwest overnight and into Saturday morning. This passing system will provide some of our Illinois communities with more than 0.50" of rainfall, though the majority of the region will see less than 0.20" of precipitation by the time Saturday evening rolls around.

Temperatures will level out in the mid to upper 50s early on tomorrow before sharply turning downward as we roll into the afternoon. Blustery winds flowing in behind the departing low pressuere system will allow cooler, Canadian air to reach back into the Midwest. The mercury will gradually drop throughout our Saturday leaving us with morning lows come Sunday in the mid to upper 30s. While our Sunday looks primarily dry, another passing system south of the Tri-State may generate some scattered rainfall south of the Ohio late Sunday evening; expect highs that day in the mid to low 40s.

Following a quiet, clear and cool start to our work week (Monday: 44° and sunny), Tuesday and Wednesday may take a page right out of winter's book. A system originating from the Central Great Plains is currently projected to track up the Ohio Valley beginning Tuesday evening. Originally, it looked as though this system would bring about a rainfall event with some wintry mix on the back end - however, these most recent model runs indicate that colder air could intermix with the gulf moisture and produce accumulating snowfall late Tuesday and Early Wednesday.

Obviously, we're in the early stages here, but it's important the know that there is a possibility of winter weather next Tuesday night and Wednesday morning. That being said, an awful lot can and will likely change between now and then - here's what can and may change:

1. Overall Timing
2. Projected Track
3. Type of Precipitation
4. Amount of Precipitation
5. Likelihood of Precipitation

We're seeing a trend, right? Just because model data currently suggests we may see winter weather five days from now doesn't mean the model data won't drastically change tomorrow. We'll continue to keep a very close eye on this impending system and update you all on new inforamtion and projections as they become available.
