136 FXUS64 KOUN 132002 AFDOUN Area Forecast Discussion National Weather Service Norman OK 302 PM CDT Thu Jun 13 2024 ...New SHORT TERM, LONG TERM... .SHORT TERM... (This evening through Friday) Issued at 241 PM CDT Thu Jun 13 2024 Thunderstorms are developing this afternoon along a cold front in Kansas and a weak surface trough in northeast New Mexico/western Kansas. Ahead of the front in Oklahoma and western north Texas, a capping inversion will prevent develop through the afternoon/evening. Storms that form to our west and north may move into northern (northwest) Oklahoma mainly after 6-7 pm. Weak mid-level flow and high-based clouds will support strong to damaging wind gusts with some of the storms this evening. Storms that reach north central Oklahoma will be later in the evening and should have a reduced risk of strong winds. Another hot day is in store for Friday, as the upper ridge builds over Oklahoma and western north Texas. Surface winds are expected to be lighter Friday afternoon, but dewpoint temperatures and humidity are expected to be slightly lower. Afternoon heat index values will approach 105 across northern Oklahoma, but should remain just below advisory levels. && .LONG TERM... (Friday night through next Wednesday) Issued at 241 PM CDT Thu Jun 13 2024 A shortwave trough will lift northeast across the southern/central Rockies Friday into Friday night. Increasing lift associated with this feature, and a stalled weak front across southern and western Kansas, should result in thunderstorm development. Thunderstorms that form should generally move northeast, so thunderstorm chances will remain rather low for Friday night into early Saturday. The timing of the shortwave trough lifting across the central Plains on Saturday may not be ideal for late afternoon or early evening storms. For now will keep mainly slight/chance PoPs in the forecast for northern Oklahoma. By late in the weekend into early next week, the synoptic pattern will place the southern Plains between a ridge over the eastern third of the U.S. and a developing trough to our west. This should favor a deep southerly flow through roughly 700 mb. This is expected to bring slightly cooler daytime temperatures with low chances of showers and storms. The thunderstorms should generally be confined to parts of western and southeast Oklahoma. && .AVIATION... (18Z TAFS) Issued at 1207 PM CDT Thu Jun 13 2024 Rather uniform southerly to south-southwesterly winds are expected throughout the TAF period. Those will peak this afternoon with many sites seeing 15+ knots sustained, and then most sites will drop near or below 10 knots tonight and remain that way through midday tomorrow. Skies will be VFR uniformly with the potential exception of northwest/northern Oklahoma this evening, where a cluster of storms may impact the area between about 0Z and 04Z. Gusty winds and reduced ceilings/visibilities are possible. Meister && .PRELIMINARY POINT TEMPS/POPS...
