822 FXUS64 KOUN 301148 AFDOUN Area Forecast Discussion National Weather Service Norman OK 648 AM CDT Thu May 30 2024 ...New AVIATION... .SHORT TERM... (Today and tonight) Issued at 220 AM CDT Thu May 30 2024 MCS season continues. Two different complexes of storms are organizing on radar and are set to move through our forecast area over the next several hours into the morning. The first originates with the storms currently over southwest Kansas, moving them through northwest Oklahoma between 3 and 7 am. These would be supported by a low level jet extending over the panhandles into western Kansas, eastern flank of the jet over northwest Oklahoma. These storms could be initially strong to marginally severe (damaging winds being the main threat), but should diminish quickly as they move east of the low level jet. The second round originates with the storms northeast of Lubbock and would pass southeast through western north Texas / southwest Oklahoma. Instability and moisture are more ample through this region, but the low level jet appears weaker. This environment would seem to be a bit more supportive of marginally severe storms (again, mainly a wind threat, with an additional concern for localized flooding with training storms). Daytime showers and storms will largely consist of the remnants of these two MCS`s making their way eastward. Behind them, we should see a lull in activity until the next round starts over the panhandles late in the afternoon, though a few CAMs do produce some isolated to scattered convection in western Oklahoma this afternoon. Models are fairly consistent about bringing together storms off the dryline this afternoon into an MCS that will traverse our area this evening and overnight. Instability and low level shear (with upper level support of a shortwave) should be supportive of severe wind gusts with this complex. With the multiple rounds of storms, heavy rain will also be a concern. Day && .LONG TERM... (Friday through Wednesday) Issued at 220 AM CDT Thu May 30 2024 Models suggest that the MCS pattern will continue into the weekend, albeit with lower confidence (20-30% PoPs). These low rain chances continue into next week through the end of the forecast period under more or less zonal flow. Temperatures start to gradually increase this weekend into early next week as the upper ridge tries to nudge back into the area and daytime precipitation chances diminish. Day && .AVIATION... (12Z TAFS) Issued at 647 AM CDT Thu May 30 2024 Areas of showers and thunderstorms are moving across western Oklahoma and western north Texas moving east. This is just the first wave of a few waves of storms that will affect the area today, tonight and overnight. Some severe weather will be possible, especially with the complex of storms this evening and overnight. Areas of IFR ceilings have developed in southern Oklahoma (KDUA, KADH, KDUC, KSNL). The IFR ceilings are expected to become less widespread with ceiling heights lifting in general today, but MVFR and potentially IFR ceilings will likely redevelop overnight. && .PRELIMINARY POINT TEMPS/POPS...
