413 FXUS64 KOUN 110812 AFDOUN Area Forecast Discussion National Weather Service Norman OK 312 AM CDT Sat May 11 2024 ...New SHORT TERM, LONG TERM... .SHORT TERM... (Today and tonight) Issued at 312 AM CDT Sat May 11 2024 Increasing clouds should spread northeastward across the FA today as the closed upper low pressure system approaches from the west. Arrival of precipitation has trended a bit later with the slow forward progression of the upper trough. Mostly rain showers should begin to overspread western north Texas by late afternoon as the upper low reaches the four corners region. Instability should be very low, but cannot rule out an isolated thunderstorm this afternoon. High temperatures should rise into the upper 70`s and low 80`s today and winds shift to the south as surface high pressure exits our area. Moisture return then begins tonight with dewpoint temperatures beginning to rise. This will keep overnight low temperatures in the mid to upper 50`s. While there is a chance of rain tonight, high POPs don`t move into our area until Sunday morning. Thompson && .LONG TERM... (Sunday through Friday) Issued at 312 AM CDT Sat May 11 2024 As the closed upper low exits the Rockies and approaches western Kansas on Sunday, showers become more numerous and continue throughout the day as WAA strengthens and isentropic lift deepens. This will lead to cooler temperatures, with highs in the 60`s and 70`s. The severe thunderstorm potential across our western counties appears to be diminishing on Sunday as latest model runs shift the instability axis more into the Texas panhandle. The closed upper low then slowly tracks across the Kansas and rain chances linger over much of Oklahoma on Monday with a marginal risk of severe storms over southeastern Oklahoma as a warm front approaches this area. A short respite is expected on Tuesday as the upper trough departs. Then, shower and thunderstorms appear likely on Wednesday afternoon and Wednesday night as a southern stream trough approaches. Due to timing differences among models, rain chances (though lower) continue into Thursday. Thompson && .AVIATION... (06Z TAFS) Issued at 1032 PM CDT Fri May 10 2024 VFR conditions will continue through the TAF period. Light and variable winds will continue through the night, gradually becoming more southerly (though still somewhat variable) through the day Saturday. && .PRELIMINARY POINT TEMPS/POPS...
