Area forecast discussion, Aug 30, 3:20 PM CDT, 1 hour 17 minutes before
Area Forecast Discussion National Weather Service Tulsa OK 320 PM CDT TUE AUG 30 2016 .DISCUSSION... As in previous days...there is a weakly sheared unstable airmass in place...with scattered thunderstorms developing again across the area. The main concern with these storms is strong wind gusts and of course lightning. Any individual storm will be short lived and overall coverage will diminish this evening. Winds will remain light over the area...with lows overnight falling into the mid/upper 60s in some locations. A weak cold front will approach the area tomorrow...bringing increasing clouds and a better chance for showers/thunderstorms. Temperatures will have a chance to rise into the 90s across western AR and SE OK...while the northern portions of our area will have clouds and precipitation earlier in the day. Models hint that storms may persist into Wed night/overnight Thu across SE OK and wrn AR so left higher chances for rain there. By Thursday...airmass will be a bit cooler and drier. Mid level ridge begins to build back by Friday into Saturday...with hot and humid conditions expected by Sunday and Monday. && .PRELIMINARY POINT TEMPS/POPS...
