Area Forecast Discussion National Weather Service Tulsa OK 114 PM CDT Sun Aug 28 2022 ...New SHORT TERM, LONG TERM... .SHORT TERM... (Thru Tonight) Issued at 114 PM CDT Sun Aug 28 2022 Persistent band of mid level cloudiness has slowed diurnal heating across much of NE OK into far NW AR so far today, but satellite trends are showing more breaks in the clouds. The latest CAMs are not all that excited regarding coverage of afternoon/evening storm development, and favor the area behind the mid-level cloud band to the west and the eastern/southern areas ahead of it where more insolation is occurring. Any storms that can develop should have 2-3k j/kg of cape, 2+" PWATs and around 20kts of 500mb flow near the base of a passing shortwave trough to work with. Water-loaded downdrafts could produce severe microbursts beneath the taller/stronger cells. The HREF PMM QPF continues to indicate the potential for locally heavy rainfall as well, which makes sense given the PWATs in place. Lacy && .LONG TERM... (Monday through Sunday) Issued at 114 PM CDT Sun Aug 28 2022 Locally heavy rainfall potential will linger thru Monday morning, though coverage should be low. The latest blended guidance has backed off from the likely PoPs for Monday afternoon, with the NAM again fairly sparse across our area and HRRR showing more spotty coverage. As was mentioned yesterday, a frontal boundary will still be to the north over KS during the afternoon, with storms expected to focus along it. Some of this activity may drop south into NE OK Monday evening. Storm chances will continue Tuesday as the boundary moves south across the region, lowest north highest south. Drier deep layer airmass behind the front will bring tranquil weather for the remainder of the week. Low rain/storm chances will return by next weekend as moisture returns from the south. Lacy && .AVIATION... (18Z TAFS) Issued at 1214 PM CDT Sun Aug 28 2022 Isolated to widely scattered RA/TSRA is expected to develop this afternoon, though coverage at any one TAF site will remain low. Will include VCTS at all sites early in the period except KBVO and KFSM. Otherwise, VFR elements will prevail at all sites through the valid period. && .PRELIMINARY POINT TEMPS/POPS...
