NWS Tulsa, OK wrote its last area forecast discussion before the first event at Aug 7, 2:48 AM CST, 51 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE TULSA OK 348 AM CDT THU AUG 7 2014 .DISCUSSION... ONGOING CONVECTION TAKING UP A LOT OF TIME THIS MORNING. THE SOLUTION FOR THE MORNING POPS WILL BE A COMBINATION OF RADAR EXTRAPOLATION AND THE HRRR/RAP SOLUTION. BOTH THOSE MODELS LET THE PRECIP DIMINISH AROUND MID MORNING. THERE WILL BE A CHANCE OF ADDITIONAL STORMS THIS AFTERNOON AND INTO THE EVENING GIVEN THE PROXIMITY OF THE WEAK FRONT. ALL THIS WILL MAKE MAX TEMPS A PROBLEM TODAY. MADE SOME MINOR ADJUSTMENT FOR THIS MORNING PRECIP BUT STILL KEPT IT VERY WARM. PREFER NOT TO HIT THE HIGH TWICE. FRONTAL BOUNDARY HANGS IN THE AREA THROUGH MONDAY...THEN PUSHES SOUTH ON TUESDAY WITH HIGH PRESSURE BUILDING SOUTH FROM THE NORTHERN PLAINS. THAT SHOULD END PRECIP CHANCES FOR AT LEAST A SHORT PERIOD NEXT WEEK. WILL KEEP TEMPERATURES SEASONAL WITH HIGHS IN THE LOWER 90S...BUT SLIGHTLY DRIER AIR SHOULD MAKE IT PRETTY COMFORTABLE FOR THIS TIME OF YEAR.
