WPSD meteorologists have activated a Climate Authority Alert for Monday night into Tuesday morning for the primary doubtlessly impactful winter climate occasion of the season.
We at present have a Winter Climate Advisory in place for many of West Kentucky, Northwest Tennessee, and the Missouri Bootheel starting at 6 p.m. this night. The Nationwide Climate Service is engaged on including counties to that advisory.
We expect some mild blended precipitation to start transferring into the world from the west between 4-6 p.m. Initially, this can be some chilly rain, blended with occasional sleet and snow. As temperatures cool via the night, a few of this mild rain might start to freeze, forming a glaze on some surfaces and untreated roads. Ultimately, extra of it will change to snow, particularly for areas alongside and north of the Ohio River. Some areas of Southern Illinois might see as much as an inch of snow, presumably 1-2″ close to I-64. Areas of Kentucky and Tennessee are more likely to see lower than an inch of snow — and a few areas might not see any.
It’s doable that some areas, particularly over Kentucky and Tennessee, might not see greater than some flurries or freezing drizzle. Freezing drizzle may be fairly misleading, as a result of whereas it does not appear like a lot, it does not take a lot to trigger issues — particularly on bridges and overpasses. With temperatures within the 20s tomorrow morning, any areas of sunshine icing may very well be fairly slick.
Whereas this isn’t a significant winter storm, it’s the first potential winter climate impacts of the season and we wish to alert people to be further cautious. Enable further time for journey tonight and tomorrow morning. Decelerate, and be vigilant of potential black ice. With sunshine returning tomorrow afternoon, we’ll see a fast enchancment in circumstances.
