Rain, Ice and Snow Arrives Tonight

Wintry mixture impacts the Tri-State.

Posted: Dec 15, 2020 6:20 PM

I'm tracking a mixture of rain and snowfall that will settle in over the Tri-State late tonight and early tomorrow morning. The first of the scattered precipitation will reach our westernmost counties shortly after dinnertime before spreading eastward across the region during the ensuing hours. Surface temperatures lingering in the mid to upper 30s this evening will keep any precip before midnight from transitioning into ice or snow. That transition however, will begin to occur during the predawn hours on Wednesday.

Temperatures north of Evansville will dip as low as the upper 20s and low 30s as the system passes through Wednesday morning. As a result, areas along and north of I-64 and west of the Wabash River will see the greatest risk for ice and snowfall. Obviously, the periodic wintry mixture and snowfall will make for a hazardous travel tomorrow morning and early afternoon, especially for the areas north of Evansville. The last of the organized wintry precipitation will pass east of the region around our lunch hour Wednesday, leaving the northern third of the Tri-State with minor accumulation up to an inch.

However, it's likely that much of the accumulation we see Wednesday won't linger much longer than that night - temperatures on Thursday will creep back up to 40° and above area-wide and Friday looks even warmer. In fact, after reaching 46° on Friday afternoon, temperatures will continue to surge throughout the Tri-State. By the time Monday rolls around (the official beginning of the winter season) temperatures will have reached the mid to low 50s!

Sure, yesterday's passing cold front and lingering rainfall made for a cooler-than average, fall-like day across the Tri-State - today on the other hand, was a bit more summer-like. The core of high pressure flowing in behind that cold front has now settled to our east and is actively pumping southerly winds, more heat and gulf humidity back into the Ohio valley. As a result, temperatures pushed back into the mid 80s for the majority of the region; the added humidity even made it feel a few degrees hotter as well. As for the rest of the evening, conditions will remain dry with temperatures gradually falling from 80° around dinnertime into the mid to low 70s by 10PM. The combination of added cloud cover overnight and those aforementioned southerly winds will help keep temperatures mild tonight - we'll only dip as low as 67° early Friday morning in the River City.
