Another round of rainfall will reach the Tri-State just as we ring in the New Year, making the first few hours of 2021 pretty interesting. Temperatures throughout the region will be in the mid 30s around midnight as the first raindrops begin to fall across our westernmost counties. With temperatures near the freezing mark, it's possible that some of us could see a period of icing overnight, especially for those of us west of the Wabash River. The National Weather Service has issued a Winter Weather Advisory for Hamilton, White, Wayne, Edwards, Wabash, Richland and Lawrence Counties that will go into effect at 9PM this evening - the primary timeline for ice potential will be between 12AM and 4AM.
As January 1st rolls on, temperatures will begin to rise, any ice we see will likely melt quickly and we can start talking about the possibility of heavy rainfall spreading across the remainder of the area. Showers and even thunderstorms look as though they will be likely through at least 9AM or so. in fact, between the hours of 5AM and 9AM, there's a slim possibility that some of the heavier bursts of rainfall could generate not only a few rumbles of thunder, but also broad tornadic rotation as well. Now, I'll tell you here and now, the likelihood of this occurring remains quite low and any significant threat of Severe Weather will remain well to our southeast, but there remains a slim possibility nonetheless.
So, remember, the fist 9 hours of 2021 could be a little on the bumpy side - first, rain and ice between 12AM and 4AM for some of us and second, potentially rotating thunderstorms for the rest of us between 5AM and 9AM - Let's just hope this isn't a harbinger of things to come during the year ahead.
