SHORT TERM
(This afternoon through Tuesday)
Issued at 1146 AM CST Mon Dec 8 2025

Cold air has been filtering in across the area this afternoon in the wake of a cold front that passed just after midnight last night. Because of this and the cloud cover that has been observed all day, temps have struggled to get to the mid-50s this afternoon. The cold air advection is expected to slack off around or just after midnight tonight as a surface high pressure filters into the area. This will set us up for a radiational cooling night on top of the colder airmass. However, high-resolution short-range models show that low-level clouds are going to stick around throughout the night tonight. Cloud cover during a radiational cooling night will lead to warmer temps than expected, so the NBM 75th and 90th percentile were blended with the deterministic NBM to raise the minimum temps. This keeps freezing temps confined to isolated areas in southwest MS and the Pearl River Basin. Meanwhile, most other places across the area should stay in the mid to upper 30s tonight.

The surface high is expected to continue sliding east during the day tomorrow and, due to that, will get onshore return flow across the area. Granite, this will only warm us up by a few degrees, but at least this will be the start of a warming trend heading into the middle of the week. Although we start getting onshore flow, our PW will be right at the 10th percentile for this time of year, so we will remain dry during the day tomorrow under the surface high and dry air aloft.

LONG TERM
(Tuesday night through Sunday)
Issued at 1146 AM CST Mon Dec 8 2025

The previously mentioned surface high pressure is expected to continue shifting eastward throughout the day on Wednesday.
Because of the continued onshore flow from this, we will warm up another 10 or so degrees from Tuesday as high temps are expected to get into the mid to upper 60s across the area.

Troughing across the mid MS valley is expected to break down that surface high late Wednesday evening. Models start to diverge here in the strength of the trough, therefore, they also disagree on the strength of the front itself. Regardless, it seem as though temps will drop by at least a few degrees on Thursday. This front will likely not have any rain associated with it as upper-level dry air hangs around and PW remains right at or just under the median for that time of year. So, just mainly expect a slight drop in temperature and dew point when the front passes through on Wednesday evening.

Model spread in the NBM and ensemble guidance really picks up towards the end of the week and into this weekend. The differences start in the strength and placement of the trough ejecting across the northeast CONUS. This leads to more differencing in the trailing ridging across the middle of the country and troughing coming onshore the western CONUS. Because of the amount of differences, opted to maintain NBM for the end of the week and into the weekend.

AVIATION
(00Z TAFS)
Issued at 630 PM CST Mon Dec 8 2025

Cloud deck with bases near FL025 across all terminals, but the cloud deck is not solid overcast. So, there will be periods where observations will cover the gamut from SKC to OVC during the night. Don't anticipate IFR conditions at this time. We should lose any ceilings Tuesday morning as thermal trough should be to our east.

MARINE
Issued at 1146 AM CST Mon Dec 8 2025

Cold air in the wake of a strong cold front will produce hazardous conditions over the waters through the daytime and evening hours today before gradually subsiding. High pressure moving into the coastal waters Tuesday and Wednesday will produce more favorable marine conditions. The next frontal system to affect the coastal waters will likely move through around Friday.
