DISCUSSION

Issued at 254 AM CST Sun Dec 28 2025

Through Tonight: Blankets of low clouds have spread across much of south and east MS and areas west of the MS River early this morning. There is also much more limited coverage of patchy fog in spots. Coverage of low clouds and fog may expand further through daybreak. Looking ahead to today, clouds will increase ahead of our next storm system, and warm, muggy winds will be gusty at times through the day. Scattered warm advection showers will be possible mainly across south/east MS late this afternoon into early this evening, but the primary rain chances will come along and behind a cold front that advances across the area this evening into the overnight. Along the front there will be a narrow but gusty band of showers. Thunder cannot be ruled out but should be limited in scope. Additional scattered showers are expected to follow the front, but overall storm total amounts will be less than a quarter inch at most locations. Though there is some potential for limited impacts from wind gusts in the upper Delta ahead of the front this afternoon, stronger wind gusts are expected along and immediately following the cold front tonight. Given this, we will expand the limited wind threat to include the entire area and shift the timing focus into tonight and early Monday morning.

Monday through Saturday: Strong cold advection will move in behind the front. As showers taper off very early Monday, it will be blustery and increasingly cold. Wind chills in the teens are expected Monday night into Tuesday morning across much of the area. It will remain cold through the day Tuesday. However, wind will slack off as the surface ridge axis moves over the area Tuesday night into Wednesday morning, which might be the coldest morning at most locations with lows in the lower 20s possible, though apparent temps won't be as extreme due to the lighter wind.

Revelers can expect a cold night for New Years Eve festivities, though thankfully not as cold as previous nights. We'll see temps begin to rebound on New Years Day. Continued surface ridging will maintain dry conditions through Thursday, but a few showers may return late Friday into early Saturday as a southern stream system moves across the Deep South. Thunder cannot be ruled out with that system, but the current timing does not appear to favor any severe threat. /DL/

AVIATION

(18Z TAFS) Issued at 1210 PM CST Sun Dec 28 2025

VFR ceilings mostly prevail, but sporadic drops to MVFR can't be ruled out at times. Gusty winds will be the main concern, with southerly wind gusts of 30 to 35mph possible at GLH and up to 20 to 25mph at sites along and north of a line from HEZ to JAN/HKS to GTR. A strong cold front with some showers will move into the northwest at GLH around 29/02Z Monday and propagate southeast through around 29/08-12Z Monday. Gusty northwest winds will prevail in the wake (LLWS of 30kts at 2kft at times). Some gusts could exceed 40mph at times through daybreak Monday for northwest TAF sites of GLH, GWO and HEZ, while up to 30 to 35mph elsewhere through the end of the 18Z TAF cycle. /DC/
