Quiet weather is expected to continue through the night ahead and linger for much of our Saturday ahead - temperatures will gradually dip toward the mid 20s overnight setting you up for a relatively pleasant, yet cool, start to the weekend. Unfortunately, those pleasant conditions aren't expected to last all that long; after seeing temperatures reach the mid to low 40s under increasing cloud cover tomorrow afternoon, a mixture of rain and snow will reach our westernmost counties between 6PM and 7PM Saturday evening. The rainfall is expected to last for a short period as temperatures quickly drop following the arrival of the precip - the transition over to a full-on snowfall event will occur by 9PM.
As the snow fall and temperatures at the surface dip, roadway temperatures will begin to cool and the snow will begin to stick to roads, sidewalks and other pavement in Evansville as early as 10PM. This will hold true for the entire Tri-State, as colder air filters further eastward, pavement temperatures will fall, delaying accumulation until later in the evening. Despite the delay, some areas are still expected to receive decent accumulations.
By the time it's all said and done (4AM Sunday), areas along and south of the Ohio may be faced with 0.5" to 1" of snowfall, whereas communities along and north of the Ohio River may see upwards of 2.5" of accumulation - the further north you go, you'll face a higher likelihood of receiving more than 2" of snow by the predawn hours Sunday. Areas such as Richland and Lawrence Counties in Illinois and Knox and Daviess Counties in Indiana stand to receive the greatest amount of snow. In addition to the shoveling many of us will be dealing with Sunday morning, we may also be weathering our coldest temperatures in a month and a half. The current forecast low for the River City of 15° will mark our lowest temperature since Christmas morning when we dipped to 13°. Worse yet, wind chill values may dip to and even below 0° at times that morning! Stay warm!
