.DISCUSSION... Issued at 140 PM CDT Wed Sep 17 2025
Tonight and Thursday: The blocking pattern that has been dominating our weather the last several days will continue to break down through Thursday. This will result in a continued light northwest to northerly flow across our region. Weak surface ridging will continue over our CWA as well resulting in a mostly light south to southwest wind. Although rain chances will remain very low and isolated afternoon shower or thunderstorm can`t be ruled out during peak heating. Our lows tonight and highs Thursday will continue to run warmer than normal. Our normal lows run in the lower 60s while our normal highs run in the mid 80s. /22/
Quiet conditions will prevail across the CWA for the rest of the week, with a slight chance of an isolated shower or two (and thunderstorm) mainly along northwestern portions of the area through the weekend.
Rain chances will begin to pickup starting next week to about 20-30% across all zones, due to a shift in the overall upper air pattern bringing a broad trough and northwest flow over AR/LA/MS. Expect diurnally driven convection for the afternoon through early next week which could have severe characteristics, so it is advised to stay apprised of all current updates regarding next week`s weather pattern./OAJ/
