Area Forecast Discussion National Weather Service Norman OK 1041 PM CDT Fri Aug 16 2019 .DISCUSSION... && .AVIATION... Gusty south wind and VFR conditions are expected until 172400. Thunderstorm chances remain too low for inclusion in TAFs for Saturday afternoon. && .PREV DISCUSSION... /issued 700 PM CDT Fri Aug 16 2019/ DISCUSSION... AVIATION... Gusty south wind and VFR conditions are expected until 172400. Thunderstorm chances remain too low for inclusion in TAFs for Saturday afternoon. PREV DISCUSSION... /issued 248 PM CDT Fri Aug 16 2019/ DISCUSSION... Most of the convection that developed across north central Oklahoma this morning has dissipated or moved into northeast Oklahoma. A diffuse outflow boundary from morning convection may help with the develop of a storm of two, mainly where higher dewpoint temperatures and slightly cooler mid-level temperatures remain. Othewise, upslope flow should result in an organized area of convection over the higher terrain this afternoon/evening. Most of this precipitation should remain north of the area given rather warm mid-level temperatures. A few models suggest that confluent mid-level flow over western Oklahoma and a rather strong low level jet may be sufficient for widely scattered showers/few storms by early Saturday morning. If this occurs, most of the precipitation should end by late morning. Another shortwave trough may help in the development of a few showers and storms Saturday afternoon and evening. Thereafter, slow height rises associated with a building ridge will bring very hot and dry weather through at least the middle of next week. Some relief from the heat may arrive by mid/late week. Models however differ on the strength and southward extent of the cooler air. Heat headlines will likely be needed over the weekend, perhaps early next week. && .PRELIMINARY POINT TEMPS/POPS...
