Area forecast discussion, Aug 29, 1:27 PM CDT, 15 minutes before
Area Forecast Discussion National Weather Service Tulsa OK 127 PM CDT Mon Aug 29 2022 ...New SHORT TERM, LONG TERM... .SHORT TERM... (This Afternoon and Tonight) Issued at 127 PM CDT Mon Aug 29 2022 Overachieving convection that has lingered from the morning hours continues to the west of Tulsa. Convection is advancing east with its outflow, given lack of flow aloft. None of the 12Z CAMs have modeled this well, and its taken till the 17Z run of the HRRR to finally start catching up. Basically a weakly capped and moderately unstable airmass in place over the region, and the 17Z HRRR gradually increases coverage across NE OK and NW AR thru this evening. An axis of 2+" PWATs are lying across NE OK into SE KS/SW MO where the bulk of the convection is currently. Current thinking is that one or more small clusters of storms will slide east and south across NE OK/NW AR thru evening with a damaging wind and locally heavy rainfall threat. Some indication in the 12Z CAMs that another round of convection developing near/along advancing cold front across KS will drop south into NE OK/NW AR late tonight as well. Lacy && .LONG TERM... (Tonight through Monday) Issued at 127 PM CDT Mon Aug 29 2022 A frontal boundary will advance south across the region Tuesday, in response to a strong shortwave trough sliding across the Midwest and Great Lakes. While the meteorological term for this boundary is a cold front technically, it will not feel "cold" behind this boundary. We will notice the much drier air, at least. Isolated to widely scattered storms are possible, mainly I-40 south. The much drier deep layer airmass behind the front will bring hot and tranquil weather from Tuesday evening thru the end of the week. Rain/storm chances will return by the latter part of the weekend, especially in the terrain, as moisture returns to the region from the southeast. Lacy && .AVIATION... (18Z TAFS) Issued at 1211 PM CDT Mon Aug 29 2022 Early in the period, convection will be focused primarily across parts of NE OK, with coverage remaining scattered through the afternoon. Will include VCTS and tempo groups KBVO. Will include VCTS for now at KTUL/KRVS sites through 00z. Elsewhere, Isolated convection will be possible across SE OK and NW AR, though coverage will likely remain too limited to include a TAF mention. Outside of TSRA, VFR elements will prevail. && .PRELIMINARY POINT TEMPS/POPS...
