(WYMT) - Cold temperatures will stick around as our next system continues to slowly move into the region. Right now, that low-pressure system can be found out in the Central Plains. So what can we expect before the actual system?
Mostly clear skies will be the main story tonight as temperatures continue to dive into the upper teens and lower 20s. Expect another cold night in the mountains. That means the winter coat will be needed for your Friday morning commute.
There should not be any problems on Friday. Friday looks a little better temperatures wise. After that frigid start, we will see highs reach the upper 30s to lower 40s. Mostly sunny skies will give way to sun and clouds later in the afternoon. As we head into the overnight hours, expect clouds to increase. Snow chances will arrive late Friday and into Saturday morning.
This system has been a tough one for snow lovers. The northward trend continues, even if it is slightly to the north. So what can we expect? Snow chances will arrive late Friday and into Saturday morning as mentioned above. The first initial round of snowfall could cause some problems in Eastern Kentucky. Light accumulations will be the main story for Saturday morning before rain chances work into the area.
The track of the low pressure will work warm air into the region. That will increase rain chances from south to north and end the snow chances sometime on Saturday. Look for afternoon highs to climb into the mid-upper 30s depending on your location. The main question continues to be: where will the rain/snow line end? Right now, models like the line being along I-64. Areas north look to receive more snowfall. Areas south should transition to rain by the afternoon.
We are still 36 hours away and a southern track is still possible. Models have done crazier things. There is also the chance that this thing could go further north, eliminating snowfall totals for some entirely.
We will expect a slight shift south in the rain/snow line Saturday night and into Sunday morning but I do not expect it to be a huge shift. Even then, snow that falls will have to overcome wet roads to stick. That could be the challenge.
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 late on Sunday. In fact, that will bring the possibility of more snow chances late Sunday and into Monday. Look for highs Sunday to reach the upper 30s to lower 40s. Lows will drop back below freezing Sunday night.
What We Know
The main impacts at this time look to be early Saturday.
Snow will be the start of this system with rain following sometime Saturday, once again, it depends on temperatures.
The further north you are, the better chances for accumulating snow.
The further south you are, the better the chances for a quicker transition to rain. Rainfall will eliminate snow totals quickly.
What We Don't Know
How long will the air temperatures remain below freezing?
How cold will the ground temperatures be?
The low-pressure track.
How much warm air surges northward?
Stay tuned for more updates throughout the rest of the week.
