FXUS64 KTSA 072312 AFDTSA Area Forecast Discussion National Weather Service Tulsa OK 612 PM CDT Tue Jul 7 2026 ...New AVIATION... .KEY MESSAGES... Updated at 606 PM CDT Tue Jul 7 2026 - Isolated afternoon storms today and Wednesday, particularly in SE OK and NW AR. - Temperatures near normal today, then rising above normal for the remainder of the week. Heat indices in the low-mid 100s possible Wednesday onward. - Thunderstorm chances trend higher late week through the weekend. - The Arkansas River near Muskogee remains in action stage but below flood stage. && .SHORT TERM... (Through tonight ) Issued at 1150 AM CDT Tue Jul 7 2026 Isolated to widely scattered thunderstorms are possible again this afternoon with a mid-level low lingering over Arkansas. Storm coverage should be less than yesterday and focused more across SE OK and into NW AR. Locally gusty winds, brief heavy rainfall, and cloud-to-ground lightning will remain the primary hazards with any storms today. Convection is likely to decrease after sunset as the atmosphere stabilizes. A few isolated storms may linger into the night near the aforementioned area of low pressure/upper trough axis, but much of this is likely to remain east and south of the forecast area. Otherwise, conditions similar to last night are expected with decreasing clouds and lows within a few degrees of 70. && .LONG TERM... (Tomorrow through Tuesday) Issued at 1150 AM CDT Tue Jul 7 2026 CAMs suggest at least low potential for isolated precip near the Red River again Wednesday morning. Additional isolated showers and pulse thunderstorms will be possible again during the afternoon, with the most focus across higher terrain of SE OK and W-Central AR. Warmer afternoon temperatures are likely across the area tomorrow, especially E OK, as upper level ridging expands into the area. Wednesday night into Thursday, a shortwave ejects out of the Rockies and moves into the C Plains. This is not currently expected to impact our area much, though temperatures Thursday will likely warm slightly given an increase in southwest sfc winds. Will need to monitor dew point trends tomorrow and especially Thursday as heat indices may once again flirt with advisory-criteria...mainly for the typical parts of NE OK and the AR River Valley. Thursday night into Friday, another wave moves east into the plains and forces a frontal boundary south into or near northern portions of the CWA. Renewed thunderstorm chances occur as a result, mainly along and north of Hwy 412. The front will tend to remain nearby in some form as the upper level pattern becomes more favorable for more widespread diurnal convection this weekend. Ridging is forecast to become displaced to the west with weak troughing moving into the S Plains Saturday and Sunday. By early next week, upper ridging re-intensifies across the northern plains with the aforementioned wave sliding along the southern and western periphery. Heights generally increase over our area through midweek with warmer and drier conditions returning. && .AVIATION... (00Z TAFS) Issued at 612 PM CDT Tue Jul 7 2026 Aside from the potential for a storm in or around the KFSM terminal in the near term, VFR conditions will prevail through the period with some morning mid cloud across eastern OK and afternoon cu at all sites. The main exception will be potential for fog at KFYV. There was dense fog there last night but that was also following rain. Guidance is a lot less bullish with the fog forecast for tonight, but to hedge the going forecast for TEMPO light MVFR fog will be kept. Lacy && .PRELIMINARY POINT TEMPS/POPS...
