AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE NORMAN OK
258 PM CDT SAT AUG 7 2010
.DISCUSSION...
MAIN FOCUS THIS AFTERNOON IS WHAT TO DO WITH THE HEAT ADVISORY.
CALCULATED MAXIMUM HEAT INDICES AND OVERNIGHT LOWS SUPPORT CRITERIA
BEING MET OVER NEARLY ALL BUT OUR FAR W/SW THROUGH SUNDAY, WITH THE
AREA OF 105+ HEAT INDICES GRADUALLY EXPANDING OVER MOST OF THE AREA
EACH DAY THROUGH NEXT WEEK. AFTER COLLABORATION WITH OUR
NEIGHBORING OFFICES TO OUR N AND E... WE WILL EXPAND THE ADVISORY
WESTWARD ANOTHER ROW OF COUNTIES IN OK AND EXTEND IT ANOTHER 24
HRS THROUGH MONDAY EVENING. RATHER THAN ISSUE A WATCH BEYOND THAT
FOR AN EVENT ALREADY STARTING TO UNFOLD... WE WILL KEEP IT A
SINGLE HEADLINE AT THIS POINT AND EMPHASIZE CONTINUED HEAT INTO
NEXT WEEK WITH POSSIBLE ADJUSTMENTS TO THE ADVISORY AREA AND
PROBABLE EXTENSIONS IN TIME. THERE ALSO IS THE POSSIBILITY OF
UPGRADING TO A HEAT WARNING FOR PARTS OF THE AREA LATER ON...
GIVEN CURRENT HEAT INDEX FORECASTS NEAR OR SLIGHTLY ABOVE 110 IN A
FEW AREAS MOST AFTERNOONS THROUGH FRIDAY. BY KEEPING THE
EXPIRATION OF THE ADVISORY AT 03Z TUESDAY... WE SHOULD MAINTAIN A
BIT MORE FREEDOM TO ADJUST THE HEAT HEADLINES WITH TIME AS NEEDED.
OTHER ISSUE TODAY IS POSSIBLE EFFECTS OF THE UPPER LOW NOW OVER THE
NW GULF. MODELS AGREE ON BRINGING THIS FEATURE NW-N TOWARD THE AREA
THROUGH MONDAY... THEN N-NE ACROSS THE AREA MON-TUE AS THE
SUBTROPICAL HIGH RELOCATES EASTWARD TO TN AREA. ECMWF IS A BIT
FASTER THAN MOST OTHER MODELS TO PICK THIS SYSTEM UP AND ACCELERATE
IT OUT OF THE AREA BY TUE. REGARDLESS OF THE SPEED/TIMING... THE AIR
MASS APPEARS LIKELY TO REMAIN RELATIVELY HOMOGENEOUS OVER THE AREA
AND SO PRECIP CHANCES WILL REMAIN FAIRLY LOW. WE WILL INVOKE
STANDARD INITIALIZATION FOR MON NIGHT AND BEYOND... WHICH KEEPS ANY
POPS IN THE SLIGHT-CHANCE RANGE FOR MOST AREAS.
