FXUS64 KOUN 090646 AFDOUN Area Forecast Discussion National Weather Service Norman OK 146 AM CDT Fri May 9 2025 ...New NEAR TERM, SHORT TERM, LONG TERM... .KEY MESSAGES... Updated at 145 AM CDT Fri May 9 2025 - Low chance for showers and thunderstorms this afternoon. - Dry with very warm temperatures this week before rain chances return again towards the end of the week and into the weekend. && .NEAR TERM... (Today and tonight) Issued at 145 AM CDT Fri May 9 2025 Ridging in the west will continue to build and push the cut-off low over the Arklatex region towards the Gulf Coast. Daytime heating will bring highs in the 70s with a nice northeast breeze of 10 to 15 mph, along with increasing cumulus cloud development into the afternoon. Scattered showers and storms may develop this afternoon with MLCAPE values below 1500 J/kg. The main hazard would be lightning as weak northwesterly flow aloft will keep shear values low and unsupportive for severe weather. Mild and near-normal low temperatures in the upper 40s to 50s tonight with clearing skies and light north winds. && .SHORT TERM... (Saturday through Sunday night) Issued at 145 AM CDT Fri May 9 2025 As the ridge moves east with the northern stream flow, the cut-off low will become nearly stationary spinning over the Louisiana Coast. Moisture will become a problem over Oklahoma with decreasing chances for any additional rain chances. Weak subsidence, mostly sunny skies and light winds will give way to continued near normal highs in the 70s through the weekend. && .LONG TERM... (Monday through Thursday) Issued at 145 AM CDT Fri May 9 2025 By Monday, the cut-off low will start to be absorbed into the ridge in the northern stream as another trough digs into the western CONUS. Weak ridging aloft through mid-week ahead of the next wave, which may bring a return to rain chances towards the end of the week. Lee troughing will develop Tuesday and strengthen into Wednesday with a return to southerly surface flow. Warm air advection will give way to above normal surface temperatures rising into the 80s and 90s by mid-week. Very warm temperatures aloft will inhibit storm chances through much of the week. Timing, strength and track of the next trough axis will play a key role in the chances for storms to return to the forecast area towards the end of the week and into next week. && .AVIATION... (06Z TAFS) Issued at 1011 PM CDT Thu May 8 2025 Light north winds overnight with a few mid/high clouds. Outside chance of some stratus in the morning, mainly along and east of I-35. By mid-morning expect to see cumulus development and there could be a period during the afternoon of a ceiling, but conditions should remain VFR. North/northeast winds increase Friday morning with some gusts at or above 20kts, before diminishing again after 00Z tomorrow evening. Outside chance of isolated shower/thunderstorm across the south during the afternoon, but chances remain too low to include in forecast at this time. && .PRELIMINARY POINT TEMPS/POPS...
