Once again, a slight chance for snow is in the forecast, but there's no need to stop what you're doing and make a run for bread and milk.
A cold front is moving out of the northern plains pushing southeast. This front will bring another shot of arctic air to the WMC Action News 5 coverage area Wednesday night, which is really the main issue with this system.
Just ahead of that front, a low pressure system in the Gulf of Mexico will be driving warm, moist air north into the Mid-South. Much of the day Wednesday will be mostly cloudy with afternoon temperatures reaching the mid-50s along with a south winds at five to 10 miles per hour. Then around midday the cold front will move from north to south through the area shifting the wind to the north and ushering in the cold.
As the cold air gradually filters in behind the front, temperatures will slowly fall with the coldest air set to arrive early Thursday morning. In the meantime, there may be just enough gulf moisture to produce a little light rain or drizzle in the late afternoon and evening hours just behind the front.
As the cold air continues to stream into the Mid-South and temperatures fall Wednesday night, there may be just enough moisture left that we see a transition to some light snow. The main time frame for snow would be between 8 p.m. Wednesday until 2 a.m. Thursday.
At this time, I think the amount of available moisture for snow will be minimal, but we could see a brief, but heavy, burst of snow or flurries around the area during that time period. Cold air has a tremendous ability to extract moisture from the atmosphere and with the steady flow from the south through the day Wednesday, there may be just enough moisture to produce a light dusting of snow for some parts of the Mid-South primarily in Wwest Tennessee and Eastern Arkansas.
Right now, forecast models are in pretty good agreement that any snowfall will be a quarter of an inch or less. With afternoon highs reaching the mid-50s Wednesday, the ground will still retain some of that heat, so any snow that falls will most likely melt on contact with streets and sidewalks. I don't expect any travel problems Thursday morning, and the only areas of accumulation would be on grass and elevated objects.
With that being said, it's still not a bad idea to allow for a little extra time for your Thursday morning commute just to be safe.
By Thursday morning, the sun should be shining but temperature will likely be in the 20s and only warm into the mid- to upper 30s during the afternoon. So, this likely won't be the one that gets the kids out of school and I don't think we'll need to dust off the sled, but winter isn't over yet.
