165 FXUS64 KTSA 082338 AFDTSA Area Forecast Discussion National Weather Service Tulsa OK 638 PM CDT Fri May 8 2026 ...New AVIATION... .KEY MESSAGES... Updated at 630 PM CDT Fri May 8 2026 - Scattered strong to severe storms from mid afternoon through evening. - Thunderstorm chances continue Saturday night into Sunday. - Temps near mid May normals forecast next week w/ low rain chances. && .SHORT TERM... (Through tonight ) Issued at 1245 PM CDT Fri May 8 2026 Cold front currently passing far NW OK and will continue eastward becoming a focus for thunderstorm development by mid afternoon. Guidance is in good agreement on increasing storm coverage through early evening as storms spread east and southeastward across the region. Forecast profiles maintain a drier subcloud layer as low level moisture return is meager with strong deep layer shear that remains near unidirectional through the evening. This will favor supercells with any sustained updrafts with efficient storm splits likely leading to multiple cell interactions with time. The initial storms will be capable of large hail and damaging winds with a transition to broken line segments and damaging winds becoming the primary hazard. The eastward extent of the instability axis will be confined within the forecast area with the high value corridor more favored across E OK and points south and westward. This should result in a lesser severe risk with eastward extent while also allowing a quick stabilization trend after sunset which keeps the severe weather confined to the evening hours. The composite cold front and outflow boundary will likely push through far SE OK by sunrise Saturday. && .LONG TERM... (Saturday through Friday) Issued at 1245 PM CDT Fri May 8 2026 The aforementioned boundary will be a focus for storm development and expansion late Saturday through Saturday night. Initial storms are likely to develop well west of the region Saturday afternoon and spread eastward into the forecast area Saturday night. Severe weather potential will be lower with this eastward progression with a limited risk hail risk Saturday night. A stronger wave approaches and passes through the region Sunday through Sunday night driving a cold front south of the area by Monday. Increased forcing in advance of the wave and along the advancing front is likely to sustain the early day convection with the storms spreading southward through Sunday. Dry and mild day Monday as sfc high pressure settles over the region. Northwesterly flow aloft continues through early next week with the next cold front passing Tuesday or Tuesday night with a chance of shower and storms. The remainder of the work week is forecast to maintain temperatures near seasonal normals and mostly dry conditions. The pattern aloft may trend toward a more unsettled state by next weekend into next week and more typical of mid May. && .AVIATION... (00Z TAFS) Issued at 638 PM CDT Fri May 8 2026 Potential for thunderstorm impacts during the first 3 to 6 hours of the valid TAF period exist for all terminals except BVO. Highest potential is TUL/RVS, where TEMPOs will continue. PROB30s included at MLC and the W AR sites, where impacts are less certain given the expectation of a decline in the coverage and intensity with time. A brief period of fog development with visibilities locally to a mile, low chance of less than that, expected, especially north of I-40. Light winds and generally clear skies should occur for much of the daylight hours tomorrow. && .PRELIMINARY POINT TEMPS/POPS...
