(WYMT) - Friday and Saturday are both Severe Weather Alert Days as snow is expected to cause travel issues late Friday and into Saturday.
A Winter Weather Advisory goes into effect tonight for about half of the area and runs through noon Saturday. Lows tonight will drop into the upper 20s and low 30s. Snow showers will begin in the Cumberland Valley after midnight.
The expected time for the arrival of precipitation will be 1-3 AM as you work towards, London, Hazard, Jackson and most of the Kentucky River region.
The rest of the area can expect to see snowfall from 2-5 AM. Those locations would include southern Perry, most of southeastern Kentucky, and all of your Big Sandy locations.
Travel conditions will be rough for some, depending on how hard the snow falls. Ground temperatures should not be an issue and I think accumulation will happen where snow begins to fall. Snowfall will continue until the warmer air noses in on Saturday morning. As that warm air noses in, snow will quickly change to rain. Rain will help quickly eliminate snow accumulations in Eastern Kentucky. Southern locations will pick up on the transition first. Northern and northwest locations will be the last to transition to rain, this is the reason why they see higher totals from this event.
That rain/snow line will work just slightly north of I-64, hopefully transitioning to rain for all of the WYMT viewing area by Saturday. A slight shift south is expected back on Saturday night into Sunday morning. That looks to bring snow back to our northern counties, which could lead to some additional accumulations. Even then, snow that falls will have to overcome wet roads to stick.
As we head into Sunday, our main low-pressure system will weaken. In fact, a stronger low will begin to form to the east. This is common as the energy will begin to shift to the new and stronger low out to the east.
That new low will enhance colder air on Sunday. In fact, that will bring the possibility of more snow chances as we head throughout the day on Sunday and into Monday. Look for highs Sunday to reach the upper 30s before falling into the lower 30s on Sunday night. Snow showers will continue Monday morning, leading to some light accumulations.
Stay tuned to the WYMT Weather Team throughout the overnight hours for more information.
