Area forecast discussion, Aug 4, 3:32 PM CDT, 1 hour 23 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE TULSA OK
332 PM CDT MON AUG 4 2008

.DISCUSSION...
THE HEAT WILL LAST AT LEAST ONE MORE DAY.  TOMORROW MAY A DEGREE
OR TWO COOLER THAN TODAY BUT THE HEADLINES IN PLACE ARE MERITED.

AFTER THAT THE RIDGE BREAKS DOWN SOME AND THE RIDGE AXIS SHIFTS
WEST.  LOW LEVEL TEMPERATURE PROFILES COOL SIGNIFICANTLY AFTER
TOMORROW.  IN ADDTION...THE MUCH ADVERTISED FRONT LOOKS LIKE IT
WILL BACK DOOR INTO THE AREA THURSDAY NIGHT AND FRIDAY.  THIS
SHOULD BRING A DECENT CHANCE OF RAIN.

FROM THIS WEEKEND ON THE FORECAST IS IN DOUBT.  THE 06Z GFS AND
00Z ECMWF ARE AT ODDS WITH THEIR LATER RUNS.  THE EARLIER RUNS
KEPT THE NORTHWEST FLOW AND FRONT IN THE NEIGHBORHOOD THROUGH
MONDAY.  THE NEW RUNS HAVE SOUTH WINDS RETURNING AROUND SUNDAY.
HAVE HEDGED IN MY FORECAST.  I RAISED TEMPERATURES SOME SUNDAY
AND MONDAY WHILE COOLING THEM SOME WITH THE BETTER RAIN CHANCE
FRIDAY.  I ALSO KEPT SLIGHT CHANCE POPS THROUGH THE WEEKEND AND
INTO MONDAY IN CASE THE MODELS FLIP FLOP AGAIN.
