KEY MESSAGES

- Cooler and drier weather will develop this weekend into next week, with frost or a light freeze possible in some areas.

DISCUSSION

Issued at 154 PM CST Thu Nov 5 2026

Through Friday: Continued dry and cooler. Mid afternoon surface analysis had a nearly stationary front well to our southeast and a cold front over the mid Mississippi river valley with a weak surface high in between. Mid afternoon satellite imagery/RAP analysis showed a shortwave trough over the central Plains that will continue swinging east tonight and help send the cold front towards our CWA. Under clear skies and a near calm wind strong radiational cooling will lead to a cooler night where most sights will bottom out in the 40s. The cold front will move through the CWA as a dry cold front. Due to its timing, most sites will top out warmer than normal in the 70s. /22/

Through mid next week (Wednesday)...As the upper trough phases over the Great Plains into the upper low, it will swing east into the weekend, with subtle shortwave ridging moving in by late weekend. This will be in advance of an upper low over the Rio Grande Valley into central Mexico, with increased isentropic ascent and clouds into the weekend. 1025mb surface high will build in late weekend into the Mid South, bringing much cooler temperatures (low to upper 60s north of Interstate 20 Saturday and Sunday, while low 70s Saturday and mid to upper 60s Sunday). Seasonably cool lows, some 5F to 10F below, will be the norm (39F to 50F Friday night and 35F to 42F Saturday and Sunday nights). Patchy frost may be a concern across the region Saturday and Sunday nights. There will be some gradient wind Saturday night and more calm Sunday night, but winds should remain light enough to support some frost potential, especially in low-lying and sheltered areas. Now is a good time to ensure plants, pets, and people are considered with more routine lows nearing frost to light freeze potential. Considering adding a Limited graphic in HWO for frost during these nights, mainly in north to northeast MS.

Early to mid next week: Quiet, partly cloudy and mostly dry pattern will persist into the following week. Upper low parked over west- central TX will eject eastward, keeping moist ascent across the Gulf Coast states. Some clouds will persist during that time and cannot rule out isolated rain shower during this time. With some thermal temps warming, highs will moderate from seasonable early week to seasonably warm mid week (65F to 75F Monday to 70F to 78F by Wednesday). Lows will remain seasonably cool but gradually less cold. /DC/
