.DISCUSSION...
THE STORMS THIS MORNING SHOULD BE ONE LAST HOORAH FOR CONVECTION
FOR A FEW DAYS. STORMS WILL AT LEAST PERSIST ACROSS NORTH CENTRAL
OKLAHOMA WHILE THE HRRR AND RAP SHOW THE CHANCE OF STORMS
DEVELOPING FARTHER SOUTH AS WELL. DID EXPAND THE SLIGHT CHANCE
POPS FARTHER SOUTH GIVEN THE HRRR AND RAP SIGNAL. EXPECT STORMS TO
HAVE MOVED EAST OF THE AREA AND/OR DISSIPATED BY EARLY THIS
AFTERNOON.
FOCUS REMAINS ON HEAT OVER THE NEXT FEW DAYS. GFS INITIALIZED
DEWPOINTS WAY TOO LOW THIS MORNING OVER THE AREA SO BLENDED WENT
WELL ABOVE BLENDED INITIALIZATION FOR DEWPOINTS. TEMPERATURES WILL
BE HIGH THIS AFTERNOON ALTHOUGH NOT CRAZY HIGH... BUT DEWPOINTS
EXPECTED TO REMAIN IN THE LOW TO MID 70S WILL BRING HEAT INDEX
VALUES OVER 110 IN SOME AREAS. HAVE ISSUED A HEAT ADVISORY FOR THE
NORTH CENTRAL... CENTRAL AND SOUTHEAST FOR THIS AFTERNOON. HEAT
WILL CONTINUE TO BE THE PRIMARY WEATHER STORY OVER THE NEXT FEW
DAYS.
