FXUS64 KJAN 240616 AFDJAN Area Forecast Discussion National Weather Service Jackson MS 116 AM CDT Fri Oct 24 2025 ...New DISCUSSION, AVIATION... .KEY MESSAGES... - Potential for heavy rainfall across portions of our forecast area will be focused from Saturday evening through Sunday morning. && .DISCUSSION... Issued at 104 AM CDT Fri Oct 24 2025 The influences of high pressure at the surface and ridging aloft will keep conditions drier and warmer today. A low pressure system moving eastward across the southern US Saturday and Sunday will bring our next chance for rain. Associated with a 60-70 kt southern jet, this system will advect deep moisture (PWATS of 1.7-2.0 inches) northward into the Interstate 20 corridor. Lift, anomalously deep moisture, and the slow-moving system will set up heavy rainfall mainly to our west Friday night into Saturday, and then over portions of our forecast area Saturday night into Sunday. We'll maintain the current Limited flash flood threat for northeast Louisiana, southeast Arkansas, and southwestern and southern Mississippi Saturday night and Sunday. The greatest threat for heavy rain and flooding is likely to be overnight and early Sunday morning. As this system continues eastward into the new week, cloud cover and lingering light rain may continue into Monday. Then an amplifying ridge over the western CONUS will drive a series of reinforcing cold fronts toward our region through the end the week. Afternoon highs will be in the 60s and overnight lows in the 30s and 40s to end the week. Thursday night could actually pose the risk for the first frost in a few spots for this season - especially protected areas if winds go calm. /NF/ && .AVIATION...
