MESOSCALE UPDATE

Issued at 732 PM CST Tue Feb 3 2026

A broad band of showers continues to shift across the region this evening in advance of an approaching cold front. The front itself lags a bit behind the main shield of precipitation, now extending from around Shreveport to El Dorado to Monticello to just east of Memphis. In areas with lingering sleet cover across our upper ArkLaMiss Delta, the rain and low level moist airmass over the very cold ground resulted in dense fog through much of the afternoon, and it has now continued into the evening. Additional fog has begun to develop in areas where rain is tapering off while the front still lags behind. A Dense Fog Advisory was posted for the areas with sleet cover earlier this afternoon and has since been expanded into southeast AR. With fog beginning to spread across more of north MS, additional expansion is possible this evening. As mixing increases along the front and drier air arrives, fog should quickly erode overnight. However, a brief window of fog will be possible for areas further south until the front passes. /DL/

DISCUSSION

Issued at 1229 PM CST Tue Feb 3 2026

Today...

A broad baroclinic leaf continues to effect the region, producing a broad field shallow of precipitation over all sites. This field of precipitation should work its way through the region in a southeasterly motion clearing out by early tomorrow morning. Lows tonight will range from 48 around Hattiesburg, to near freezing along the highway 82 corridor.

Wednesday & Thursday...

As the front associated with the aforementioned baroclinic leaf clears the area, temperatures will fall once again over the next couple of days. Highs will hover in the mid 40s in all but the furthest southern reaches of the CWA, where temps will hold in the mid 50s. No real significant weather is expected beyond another bout of cold lows, with Wednesday night being our coldest as temperatures tumble into the mid to high 20s. A slight rebound is expected Thursday night, with the western half of the CWA above freezing, and the eastern half just below.

Friday Onwards...

Highs rebound into the upper 60s, and lower 70s; temperatures warming the further south one goes within our forecast zones. Lows look to finally climb out of the 30s Saturday night and stay that way for the foreseeable future. No rain/thunder/fog or any other weather phenomena is expected for the remainder of the period, so it looks like it will be a great weekend to get out side and go for a hike./OAJ/

AVIATION

(00Z TAFS) Issued at 541 PM CST Tue Feb 3 2026

A broad area of light to moderate SHRA continues to move across the area in advance of an approaching cold front. Along and ahead of the front, ceilings are falling into the IFR/MVFR range. There are also periodic visibility reductions to IFR/MVFR in heavier precip. Rain is already ending around GLH/GWO and will end from west to east overnight, tapering off around PIB/HBG early Wed morning. Winds will shift to NW/N behind the front, and may be gusty at times through the day Wednesday. Ceilings will remain at IFR/MVFR in many areas through much of the day Wednesday, but improvement to VFR is increasingly likely by the afternoon hours. /DL/
