DISCUSSION

Issued at 231 PM CST Wed Jan 14 2026

Tonight through early next week Wednesday...

A few lingering showers will be possible across southeastern portions of our CWA this evening as near term guidance shows the cold front pushing southeast across the Pine Belt. Rain chances will come to an end later tonight. Cloud cover will begin to clear from the north by midnight with mostly clear skies across our forecast area heading into early Thursday morning. With the clear skies expected across our area by midnight, radiational cooling will start to occur. This will help nighttime temperatures drop into the mid/upper 20s areawide. Some light patchy frost will be possible across a good portion of our CWA before sunrise on Thursday. Weather conditions will be generally quiet by Thursday afternoon with daytime highs peaking into the mid/upper 40s.

Guidance consensus is still showing a series of reinforcing cold fronts pushing across our area Thursday night through the late week which will help maintain dry air across the region. Conditions at this point still remain favorable for freezing/subfreezing overnight temperatures through at least early next week. With that in mind, dangerous cold is not anticipated for much of the area, however GTR will continued to be monitored for cold headlines. In the wake of this front, cold weather headlines/advisories may be needed for tonight and Saturday night. We will hold off on mentioning any HWO graphics for right now.

Some light scattered rain showers will be possible across portions of east and southeast MS by early Saturday morning and again across portions of the Pine Belt Saturday night (PoPs between 15-20%). The GFS has begun to hint at some form of possible wintry precip for parts of the Pine Belt around the Saturday night timeframe. There is not a lot of confidence at this time given that the GFS, in more recent runs, appear to be the outlier. We will continue to monitor conditions to see whether or not this is an outlier or a trend. If guidance starts to trend in the direction of the current GFS, then a mention of light snow may be introduced. GFS is beginning to show precip along the post frontal boundary that could interact with the sub-freezing cold air and introduce possible wintry precip over southwest portions of the area Monday night. Forecast confidence at this point is low given that this is several days out. Trends will continue to be monitored.

We will start to see a little break from the cold regime by mid next week as future guidance shows a 1028mb sfc high over the Tennessee Valley. This sfc high will help bring in southerly flow across much of our area allowing for nighttime lows to return to above freezing across our CWA. Scattered rain showers will make a return across our area heading into Wednesday, with slightly higher rain chances (PoPs around 30%) for areas west of I-55 including several of our northeast LA parishes. Rain will continue across our forecast area by Wednesday evening. /CR/
