506 FXUS64 KTSA 021744 AFDTSA Area Forecast Discussion National Weather Service Tulsa OK 1244 PM CDT Mon Jun 2 2025 ...New AVIATION... .KEY MESSAGES... Issued at 314 PM CDT Sun Jun 1 2025 - Storm chances increase Monday night across northeast OK, spreading through the entire area Tuesday. Severe weather is possible. - Daily shower and storm chances continue most days through the next week. - Heavy rain is expected at times over the next week, with multiple inches of rainfall. This will lead to an increasing flash and mainstem river flooding threat. && .UPDATE... Issued at 1106 AM CDT Mon Jun 2 2025 Convection has remained south of the Red River this morning and is already on a downward trend as a shortwave trough continues lifting east across the region. We will wait for the next impulse to kick out ahead of the closed low over AZ before more showers and storms arrive late this evening and overnight. For the remainder of today expect occasionally breezy south winds with highs climbing well into the 80s. Increasing moisture on the southerly flow will aid cu development most notably across the western portions of the CWA otherwise sunny to mostly sunny skies will prevail. && .SHORT TERM... (Today) Issued at 148 AM CDT Mon Jun 2 2025 Very warm weather continues Monday, with high temperatures again surging into the mid to upper 80s as southerly flow brings warm and moist air into the region. An upper level low will begin to impinge on the area late this evening. CAM guidance shows the potential for showers and thunderstorms to move into northeast OK this evening as upper level dynamics improve. For now, the probability of severe weather is low. && .LONG TERM... (Tonight through Sunday) Issued at 148 AM CDT Mon Jun 2 2025 The better upper level dynamics arrive Tuesday with a surface front also moving in. Forecast soundings show sufficient instability and wind shear to support some severe weather potential, particularly Tuesday afternoon or evening. Wind profiles would support fairly quick upscale growth of any convection, so wind will most likely be the primary severe hazard, though instances of hail and a tornado or two are possible. Of additional concern, is very high PWAT content (exceeding 2"), which is near the climatological max for this time of year (99th percentile). Considering the amount of rainfall of late, flood concerns will definitely be on the rise. EPS EFI for precipitation shows values peaking around 0.8 with some SOT, a definite heavy rain signal. The cold front will slowly slog south into Wednesday, with rain chances ending behind the cold front northwest of I-44. Southeast of there, rain chances will diminish, but not totally end, with a few scattered showers holding on into Wednesday. High temperatures will only reach the mid 70s with lows into the upper 50s to mid 60s (warmest south). Low level flow will reverse Thursday with very humid air surging back into the area. Meanwhile, upper level flow will become westerly and strengthen. With plenty of moisture and instability, any minor upper level wave will have the potential of kicking off showers and thunderstorms. Model guidance shows just that, with nocturnal rounds of showers and thunderstorms Thursday night into Friday and again Friday night into Saturday. By Sunday the flow becomes more northwesterly, but daily nocturnal MCS activity appears poised to continue into early next week. Moisture levels will remain elevated, and the daily heavy rain chances will likely result in flash and main stem river flood potential. The main uncertainty for this period is the exact MCS trajectory. The positioning of the upper level trough to the northeast, or the high to the west, will ultimately impact how stormy this period is. && .AVIATION... (18Z TAFS) Issued at 1230 PM CDT Mon Jun 2 2025 Gusty southeast winds and VFR ceilings will be the main flight impacts this afternoon across the OK terminal with fewer cu but still breezy conditions in AR. Winds calm some overnight with LLWS possible at KBVO ahead of approaching storms. Latest guidance brings a bit more confidence to convection impacting northern OK terminals between 06-09Z. More uncertainty leads to a less confident forecast after that with the possibility of additional showers or storms impacting those sites after 12Z. Have included MVFR ceilings in Prob30 group between 12Z-15Z with the likelihood of some low clouds forming across northern OK into northwest AR. Later updates may need to add a more definite MVFR period to the pre- and post-dawn hours on Tuesday. Stronger south winds than today will return by mid morning Tuesday morning. && .PRELIMINARY POINT TEMPS/POPS...
