873 FXUS64 KTSA 140128 AFDTSA Area Forecast Discussion National Weather Service Tulsa OK 828 PM CDT Tue May 13 2025 ...New SHORT TERM... .KEY MESSAGES... Issued at 215 PM CDT Tue May 13 2025 - Near record high temps possible Wednesday. - Weak cold front passes Thursday with low thunderstorm chances far E OK / NW AR. - A more unsettled weather pattern develops by the end of the week and continues through the weekend into early next week. Severe weather potential likely increases. && .SHORT TERM... (The rest of tonight) Issued at 828 PM CDT Tue May 13 2025 The current forecast remains in good shape. No significant updates are expected through the night. Southeast winds will stay light, but elevated enough to prevent any type of fog formation overnight. Temperatures will stay mild and bottom out in the mid-60s by sunrise Wednesday for most locations. Mejia && .LONG TERM... (Wednesday through Tuesday) Issued at 215 PM CDT Tue May 13 2025 Low level thermal ridge expands across the region Wednesday and the dryline will attempt to mix into E OK by mid afternoon. Near record high temps are possible where winds can become west of south and dewpoints fall appreciably. The eastward extent of this airmass change is more uncertain with widely varying solutions. The forecast will trend slightly warmer generally along and west of Highway 75 for Wednesday afternoon and forecast temps will be near record highs for the day. Higher dewpoints further east will compensate for somewhat cooler temps and maintain an early season heat stress day area wide. Weak cold front passes Wednesday night through Thursday with the boundary likely extending from far NW AR into SE OK by late afternoon. Expect a broad fetch of thickening mid level moisture ahead of the boundary and isolated early day high based showers are possible. Conditions will become increasingly unstable and weakly capped along the boundary by mid afternoon however low level convergence will be weak. The bulk of guidance favors locations further east for storm development during the evening hours but at least a low chance should remain along the front through early afternoon before it pushes east of the forecast area. The Thursday boundary looses definition by Friday as another weak front is expected to move into the region by Friday afternoon. Storm chances will develop Friday primarily along and southeast of Interstate 44. Sufficient instability and shear will be present by Friday afternoon and evening to support a risk of severe weather with any storms that develop. The warm unstable sector expands north and westward by Saturday and largely remains in place into early next week. Multiple shortwave troughs are expected to cross the Plains during this time frame and daily thunderstorm chances will exist. It appears likely that several periods of severe weather potential will develop over the weekend through early next week. && .AVIATION... (00Z TAFS) Issued at 537 PM CDT Tue May 13 2025 VFR conditions will prevail thru the period. Some scattered low cloud is possible in and around the NE OK TAF sites around daybreak Wednesday, but a cig is not expected. Inserted TEMPO mention for an FYI to pilots. South to southeast winds will become southwest during the afternoon at the E OK sites on Wednesday and will be gusty. Some passing high cloud will be observed also.
