350 FXUS64 KOUN 121646 AAA AFDOUN Area Forecast Discussion...UPDATED National Weather Service Norman OK 1146 AM CDT Fri Jul 12 2024 ...New UPDATE... .UPDATE... Issued at 1144 AM CDT Fri Jul 12 2024 Isolated elevated showers continue across portions of central OK late this morning. Isolated showers/storms will remain possible through the afternoon across the fa so added a low chance (~15%). Most locations will still remain dry but a few could see some rain this afternoon. If storms get strong enough, gusty winds will also be possible. && .SHORT TERM... (Today and tonight) Issued at 307 AM CDT Fri Jul 12 2024 The heat will continue today across the Southern Plains as the mid-level ridge slowly expands eastward in tandem with a low-level thermal ridge. High temperatures will range from the mid 90s to mid 100s deg F. A shortwave trough is resulting in showers and thunderstorms across southeast Kansas, southwest Missouri, and northeast Oklahoma this morning. The greatest ascent from this wave should remain to our northeast, so kept the forecast dry this morning (but trends will be monitored). A few showers and thunderstorms may develop late this afternoon across northern Oklahoma in a weakly capped environment (~10 to 15% chance at a given location-- so most will remain dry). If thunderstorms develop, gusty winds is the primary hazard. Any thunderstorms should dissipate during the evening with the loss of daytime heating. Mahale && .LONG TERM... (Saturday through Thursday) Issued at 307 AM CDT Fri Jul 12 2024 Hot weather will continue through the middle part of next week as the mid-level ridge and attendant low-level thermal ridge continue expand farther to the east. Heat indices by Sunday and Monday will likely reach 105 deg F or higher in some locations, which would result in Heat Advisories. The center of the ~595 dam mid-level is expected to remain across the southwest U.S., so high temperatures should remain well-below any records. While the chance for showers and thunderstorms during this period is very low, it is not zero as a weakly capped environment in southeast Oklahoma may result in daytime convection (the probability is <10%) Monday and Tuesday afternoons. By the latter part of next week (Wednesday and beyond), deterministic and ensemble guidance indicate the mid-level ridge will likely amplify and retrograde to the west. As a result, the Plains would transition to northwest flow aloft. This synoptic- scale pattern is favorable for MCSs and/or cold fronts to advance southward into Oklahoma and north Texas. Probabilistic guidance indicates a reasonable chance that high temperatures will lower into the upper 80s and low 90s deg F with at least a moderate chance of showers and thunderstorms by Thursday. Mahale && .AVIATION... (12Z TAFS) Issued at 555 AM CDT Fri Jul 12 2024 VFR conditions are expected for the next 24 hours. Winds will increase somewhat during the day today with a southerly direction. For the most part expect 10-13 knot sustained winds both today and tonight. There is an outside chance of a shower or thunderstorm across north central Oklahoma this afternoon; however, the probabilities are low enough that they did not warrant outright messaging within the TAFs.
