AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE NORMAN OK
317 PM CDT THU JUN 14 2001

COLD FRONT/SURFACE BOUNDARY CURRENTLY RUNS FROM CHANDLER SOUTHWEST
TO NEAR WICHITA FALLS.  EXPECT THUNDERSTORMS TO INTENSIFY AS THEY MOVE
FARTHER EAST INTO SOUTH CENTRAL AND SOUTHEAST OKLAHOMA LATER THIS
AFTERNOON AND EVENING WHERE TEMPERATURES HAVE WARMED INTO THE UPPER
80S AND LOWER 90S.  REFER TO SWODY1 AND MCDS ON MORE DETAILS OF SEVERE
WEATHER POTENTIAL.  12Z ETA-KF HAS DONE FAIRLY NICE JOB ON SPATIAL
AND TEMPORAL ASPECTS OF CONVECTION TODAY.  EXPECT AS MAIN TROUGH AND
SHORTWAVE PUSH OUT THAT BROKEN LINE OF STORMS WILL CONTINUE TO
FILL.  THINK THAT STORMS SHOULD MOVE FAST ENOUGH EAST THAT TRAINING
AND POTENTIAL FLOODING SHOULD BE LOW.  FFG ACROSS SOUTH CENTRAL AND
SOUTHEAST ARE ROUGHLY 3-4 INCHES IN A 3 HOUR PERIOD.  WITH COOLER
AND DRIER AIR MASS IN PLACE TONIGHT...ESPECIALLY ACROSS THE WESTERN
COUNTIES TEMPERATURES WILL COOL DOWN NICELY.  WILL GENERALLY GO WITH
OR SLIGHTLY BELOW GUIDANCE FOR LOWS TONIGHT.  CONVECTION ALONG FRONT
TONIGHT SHOULD PUSH SURFACE BOUNDARY EAST AND SOUTH OF FA SO WILL
GO WITH A DRY FORECAST FOR FRIDAY.  FULL SUN AND DRIER AIRMASS SHOULD
ALLOW FOR TEMPERATURES TO WARM TO NEAR GUIDANCE NUMBERS FOR FRIDAY.

IN EXTENDED FORECAST...MODELS FAIRLY CONSISTENT IN BUILDING UPPER
RIDGE OVER AREA FOR THE WEEKEND.  FAST MOVING WAVE IN ZONAL FLOW TO
OUR NORTH WILL HELP PUSH ANOTHER FRONTAL BOUNDARY TOWARD THE NORTHERN
PART OF CWA SATURDAY BUT SHOULD REMAIN ACROSS KANSAS.  REST OF WEEKEND
INTO MIDDLE PART OF NEXT WEEK SHOULD REMAIN WARM TO HOT AND DRY.  MRF
SHOWS ANOTHER FRONT APPROACHING AREA AROUND THURSDAY SO MIGHT ADD IN
SOME SLIGHT POPS TO ACCOUNT FOR THIS.
