(This evening through next Tuesday) Issued at 1232 PM CDT Wed Apr 15 2026 High pressure both at the surface and aloft continue to dominate the weather pattern across the southeastern U.S. today. A few, light streamer showers have been developing across southeast Texas and western Louisiana where the ridging is a bit weaker and deeper moisture exists. These have not amounted to more than just a brief period of drizzle and this isn't expected to change through the afternoon. Breezy southerly flow will maintain warm and humid conditions across the region through Saturday with afternoon highs in the mid to upper 80s and overnight lows in the mid to upper 60s. A cold front will move through the region Saturday night into early Sunday morning accompanied by a broken swath of showers and thunderstorms. A narrow swath of deep moisture along and ahead of the front will support periods of heavy rainfall. WPC has introduced a marginal risk of excessive rainfall roughly along and north of the HWY 190 corridor for the possibility of nuisance flooding from high rainfall rates. Storm totals are still expected to range between a quarter and three quarters of an inch which wont be enough to put a significant dent in the ongoing drought, but every little bit helps. Cooler, drier and much more pleasant air will advect into the region in the wake of the frontal passage Sunday with highs Sunday afternoon in the low to mid 70s. A couple of chilly nights are expected Monday and Tuesday mornings with lows in the low to mid 50s. Winds will turn back out of the south Tuesday afternoon initializing a gradual warmup through the second half of next week. Jones && .AVIATION...
