The forecast is still on track, with rain heading our way after midnight tonight with a rumble of thunder possible through noon tomorrow. Then, snow mixes in by the evening as temperatures rapidly drop. After seeing highs in the 70s this afternoon, here is a look at the big temperature changes we are expecting...
Tonight's lows are expected to stay in the 50s for most of the region. It will be mild temperature wise through 11 AM (top image), with projected temperatures in the mid to upper 50s. Then, a cold front advances into our region, and by the early evening (middle image), temperatures quickly drop into the 30s. This is when we will start to see the snow transition; however, keep in mind that the ground will still be relatively warm (ground temperature changes slower than air temperature) so it will be difficult to get an accumulation at first. Progressing into the overnight and into early Thursday morning, snowfall chances will continue with a northwest upslope flow established, Temperatures will continue to drop, with Thursday morning temperatures in the upper teens (bottom image). This coldness will support the development of ice on the roadways in addition to the accumulation of snowfall.
As mentioned in my last post, snowfall accumulations will not be huge- with a general coating to 3 inches expected. The higher elevations in West Virginia could see upwards of 4 inches due to the enhanced upslope snow they are expecting.
Have a good evening!
