Some spots dealt with as much as 2" of snowfall overnight and early Sunday morning, we also saw the mercury dip to its lowest point in the River City in nearly a year; Sunday morning's low of 11° matched our morning low on the morning of February 14th, 2020! Temperatures didn't climb all that high earlier this afternoon either - after only reaching 22°, temperatures will again sag toward the mid to low teens early Monday. Southerly winds will help drive temperatures back into the upper 30s and low 40s for many of us along and south of the Ohio Monday afternoon - however, communities north of I-64 may receive another dose of accumulating snowfall beginning between 2PM and 3PM Monday. By the time it's all said and done early Tuesday, some of our Hoosier and Illinoian counties could see up to an additional 1" of snow.
That being said, snow won't be our main concern over these next 72 to 96 hours - that distinction goes to freezing rainfall. A core of low pressure expected to track east from the Mississippi Valley toward South Carolina will supply the Ohio Valley with an ample amount of moisture by midweek; higher pressure stalled over the upper Great Plains will force cool Canadian air into the Tri-State Tuesday and Wednesday - the combination of the two may lead to our most significant freezing rain/ice event in some time.
Current model data suggests that periods of freezing rain will reach the Tri-State late Tuesday evening (around 10PM), that freezing rain will continue on and off intermixed with sporadic rain and snow through our Wednesday and into the predawn hours Thursday. The current projections indicate that as much as 0.1" to 0.25" of ice may accumulate during the period in question. Expect travel to be impacted Wednesday and into Thursday morning. Storm Team 44 will continue to keep you informed and updated on the situation as it continues to evolve.
