Area forecast discussion, Aug 7, 3:44 AM CDT, 2 hours 2 minutes before
Area Forecast Discussion National Weather Service Tulsa OK 344 AM CDT Mon Aug 7 2023 ...New SHORT TERM, LONG TERM... .SHORT TERM... (Today) Issued at 344 AM CDT Mon Aug 7 2023 Scattered convection has been developing over the last hour or so in the vicinity of an elevated frontal boundary. While the better elevated instability axis remains across SE Ok and WC AR, ample shear across the area is supportive of strong to severe storms capable of producing large hail. Axis of convection will shift E-SE through mid to late morning before dissipating. Will leave low PoPs going across the south as isolated development near a diffuse surface boundary will be possible. Lower dewpoints working south into the area will help reinforce cooler temperatures today, making for a nice break from the recent heat. && .LONG TERM... (Tonight through Sunday) Issued at 344 AM CDT Mon Aug 7 2023 The W-NW flow pattern will continue over the next several days with additional chances for storms tonight through Wednesday. Storms developing to the west and northwest later today and evening will move east into the forecast area late tonight, with most activity decreasing/dissipating by mid morning Tuesday. A stronger upper wave moving from the Rockies into the central plains Tuesday night along with a strengthening low level jet will allow convection to initiate across KS and develop into an MCS as it moves southeast through KS and into NE OK and NW AR late Tuesday night and Wednesday morning. A surface boundary will move through later in the day Wednesday with additional storms possible Wednesday afternoon and evening. However, coverage and intensity will be dependent on the evolution of the late Tuesday night/Wednesday morning convection. Settled conditions are expected behind the front for Thursday. Without strong upper ridging in place towards the weekend, there will at least chances for diurnal convection with a hot humid airmass in place. Stayed close to NBM temps throughout the forecast cycle. && .AVIATION... (06Z TAFS) Issued at 1157 PM CDT Sun Aug 6 2023 Thunderstorms are expected to form within the first few hours of the valid TAF period in a warm advection zone in the vicinity of Highway 412 and I-40. Mid cloud development has been noted in this region in satellite trends. Confidence remains highest in on station impacts, including periods of IFR conditions, at RVS and FSM, followed by TUL and FYV on the northern edge with slightly better conditions. Expect a decrease in cloud cover through the morning and into the afternoon, with VFR conditions areawide thereafter. && .PRELIMINARY POINT TEMPS/POPS...
