DISCUSSION

Issued at 110 PM CST Sat Nov 29 2025

Tonight:

Rainfall will continue tonight as a shortwave trough pushes through the region. Showers are likely with perhaps an isolated rumble of thunder not out of the question. Severe weather is not anticipated as instability/moisture are limited.

Sunday into Monday:

Primary concern for possibly heavy rain and a brief period of wintry weather continues for Sunday night through Tuesday morning as another shortwave trough moves across the area. Following tonight's front, cold air advection will become entrenched at the surface. By Sunday evening, warm air advection aloft is expected to lift moisture over the cold surface air which will bring increased clouds initially and by perhaps mid morning Monday mostly virga rainfall will have sufficiently moistened the low-levels to allow for rainfall to reach the ground. Should this moistening occur sufficiently quickly before we warm above temperatures hovering near freezing early Monday morning, portions of SE AR, NW MS Delta could see some risk for a brief period of trace freezing rain. However, meaningful accumulation isn't expected as surface/ground temps remain well above freezing. Vegetation or elevated surfaces could become briefly glazed but road surfaces are unlikely to be sufficiently cold for sufficient duration to result in meaningful road hazards. Regardless, caution should be exercised when travailing, particularly over overpasses and less-traveled areas, as roads will certainly be wet and slick regardless of ice potential. As the morning progress, any frozen precip in the NW parts of the area will transition to rain and widespread rainfall is expected through the rest of Monday and into Monday night.

Tuesday through Friday:

Cold temps are expected post-frontal passage as high range from the lower 40 in the north to lower 50 degrees in the south and lows reach the lower 20s to mid 30s Tuesday and Wednesday. Highs are expected to remain below seasonal averages; however; temps will gradually warm to where highs reach the mid/upper 50s and lows reach the mid/upper 30s. Next chances for rainfall is expected Thursday into the weekend as another shortwave trough traverse the area. Severe weather isnt currently expected with limited thermodynamic recovery anticipated and the pattern largely remaining suppressed. /SW/
