105 FXUS64 KTSA 180843 AFDTSA Area Forecast Discussion National Weather Service Tulsa OK 343 AM CDT Wed Sep 18 2024 ...New SHORT TERM, LONG TERM... .SHORT TERM... (Today) Issued at 329 AM CDT Wed Sep 18 2024 Showers and thunderstorms in northwest Oklahoma early this morning are expected to dissipate before reaching our area today. Temperatures should be warmer today due to less cloudiness, with afternoon highs generally ranging from the upper 80s to mid 90s. && .LONG TERM... (Tonight through Tuesday) Issued at 329 AM CDT Wed Sep 18 2024 The warming trend will continue Thursday and Friday as an upper ridge builds overhead, with unseasonably hot afternoon high temperatures and unseasonably warm overnight lows. Afternoon heat index values will reach near 105 in some places both Thursday and Friday afternoon, so it is possible that heat headlines may be required. A few "sunrise surprise" showers and thunderstorms may develop late tonight and Thursday morning across parts of northeast Oklahoma, and the CAMs suggest the potential for robust convection to develop across northeast Oklahoma late Thursday afternoon, with these storms possibly propagating south as far as southeast Oklahoma Thursday evening before dissipating. As such, have added pops for both of these time frames despite the dry NBM. Low shower and storm chances will remain possible in the northern part of the forecast area this weekend, and temperatures will lower slightly as the upper ridge over the area begins to break down. Better shower and storm chances look to occur Sunday night as a cold front sweeps across the area. There remains considerable model spread in the magnitude of the cooling behind this fromt for early next week, with some models...UKMET and ICON in particular...indicating a far more significant cooldown than what is shown in the current forecast. We will just have to wait and see how this all plays out. && .AVIATION... (06Z TAFS) Issued at 1240 AM CDT Wed Sep 18 2024 Scattered to broken high clouds associated with ongoing convection over the Oklahoma/Texas Panhandles to Western Kansas will continue to spread eastward into the CWA overnight tonight. At this time...the greater precip potential should remain west and northwest of Northeast Oklahoma. Also overnight...patchy areas of reduced visibility are possible and will add a tempo group to KFYV. During the day Wednesday...scattered diurnal cumulus clouds are again forecast to develop over the CWA and then dissipate Wednesday evening. There may be period as clouds develop that MVFR ceilings are possible before lifting to around 5kft for the afternoon hours. Mostly clear to scattered high clouds are then forecast Wednesday evening/night. Winds through the period should vary between east and south. VFR conditions are forecast for the majority of the TAF period. && .PRELIMINARY POINT TEMPS/POPS...
