After seeing heavy snowfall throughout much of region last night and this morning, another storm is brewing out to west. We will see a brief break tonight from the moisture before a rain/snow mix enters tomorrow afternoon. By tomorrow evening, pure snowfall is expected and now the models are starting to hint at accumulating snowfall.
Above is the NAM outlook. By the mid-afternoon, the NAM expects moisture to start creeping in from the west. Due to the proximity of the rain/snow line (temperatures will be in the mid 30s), it will likely be a cold rain and snow mix that pushes through initially. By Friday night, the rain/snow line should start to drift southward which will allow the mix to become all snow. Notice how the heaviest snowfall (darkest green colors) is expected over eastern Kentucky. By Saturday morning, the NAM expects the snowfall to become light. This will likely linger into the late morning, due to the northwest flow (upslope flow) which should develop.
Above is the GFS outlook. Similar to the NAM, the GFS also shows the initial moisture falling as a rain/snow mix in the afternoon. By Friday night, the GFS expects moderate snowfall to fall throughout most of the region, with an even heavier band setting up in eastern Kentucky. The GFS also expects lighter snow to fall in the morning; however, unlike the NAM, the GFS expects the snow to linger into the afternoon.
This snowfall is expected to be heavy and wet… once again.
For those of you that are sick of the cold, take a look at this…
By the end of next week, we start to see a shift in the pattern and a trough digs into the western half of the country.Thus, we will start to see a ridging pattern building into the southeast. With this pattern, warmer air and moisture from the southwest will be able to penetrate our region.
Have a great evening everyone!
