806 FXUS64 KOUN 110350 AFDOUN Area Forecast Discussion National Weather Service Norman OK 1050 PM CDT Mon Jun 10 2024 ...New AVIATION... .SHORT TERM... (This evening through Tuesday) Issued at 309 PM CDT Mon Jun 10 2024 This Evening: `Cool` temperatures, along with low-medium (20-40%) potential for showers/a few storms across the southwestern forecast area, are expected into the evening. Amidst a modified (dry continental) airmass, temperatures are running 5-15 degrees below average for mid-June. Coolest conditions are occurring across the Red River Valley, where cloud cover and scattered areas of precipitation have prevailed for much of the early afternoon. Early afternoon satellite imagery shows a pair of mesoscale convective vortices (MCVs) rotating across portions of the central Texas Panhandle/eastern New Mexico. Widely scattered precipitation development has been ongoing (associated with this feature) since the mid-morning and is expected across the far southwestern forecast area for another 2-4 hours. Late this evening (after ~7-8 PM), will monitor approach of a semi-organized storm cluster, which may skirt far southern portions of our Texas counties into the late evening. Severe weather potential is very low with any storm into/through the overnight, though brief periods of gusty wind/small hail potential with the strongest storms cannot be ruled out. Heavy rain and localized flooding may also emerge, especially where heaviest totals have occurred the past 24 hours (Knox/Foard/Baylor/Wilbarger counties). Tuesday: Seasonable temperatures (mid to upper-80s) return along with medium (40-60%) potential for precipitation across southwestern Oklahoma and north Texas through the evening. Short-range guidance highlights potential for a round of early to mid-morning precipitation across aforementioned areas, potentially aided by a remnant mesoscale vortex. A few thunderstorms may also develop in the period, though severe weather concern is expected to remain very low. Widely scattered precipitation cores/areas are expected into the afternoon/early evening, though forecast to become more confined (to the far southern forecast area) with time. Ungar && .LONG TERM... (Tuesday night through next Sunday) Issued at 309 PM CDT Mon Jun 10 2024 Rest of the Work Week: Hot and mostly dry weather is expected. Grand ensemble guidance highlights upper ridging across portions of the Intermountain West/Four Corners by the midweek. The impact on local sensible weather will be a transition towards hot temperatures (upper-80s to mid-90s) and dry weather, especially for Wednesday and Thursday. Weekend: The return of at least low/widely scattered precipitation chance is evident by late Friday into the upcoming weekend. Global deterministic/ensemble guidance shows a previous (cutoff) upper low across the Desert Southwest transitioning towards an open wave, while slowly progressing towards the central Plains by Friday. While uncertainty prevails relating to this feature, and resultant precipitation/storm coverage in our area, will maintain mention of at least low (20-30%) storm potential across northern/western Oklahoma by Friday night into the weekend. Ungar && .AVIATION... (06Z TAFS) Issued at 1047 PM CDT Mon Jun 10 2024 VFR conditions still expected to give way to MVFR cigs and scattered SHRA/TSRA toward and after 12Z, mainly across southwest Oklahoma and KSPS closer to moisture axis and slow moving mid level trough. At start of forecast, area of showers and embedded TSRA will likely impact KSPS but weaken to mainly showers. Most of the TSRA expected during the afternoon tomorrow near and south of KLAW/KSPS. && .PRELIMINARY POINT TEMPS/POPS...
