Severe Thunderstorm Warning 261, NWS Norman, OK

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE NORMAN OK
355 PM CDT SUN MAY 9 1999

...WITH UPDATED CCF NUMBERS...

CONVECTIVE CONCERNS WILL ONCE AGAIN HIGHLIGHT THIS FORECAST PACKAGE.
FIRST ROUND ONGOING ACROSS WEST TEXAS JUST AHEAD OF DRYLINE...AND IS
IS EXPECTED TO AFFECT MUCH OF THE WESTERN AND CENTRAL AREAS THIS
EVENING AND OVERNIGHT. THE POTENTIAL FOR HEAVY RAIN WILL
EXIST...ALONG WITH THE SEVERE WEATHER...ACROSS NORTH CENTRAL THROUGH
SOUTHWEST PORTIONS OF THE FORECAST AREA. THIS WILL BE WORDED IN THE
ZONE FORECASTS.

AFTER TONIGHT...IT DOESNT GET MUCH BETTER. DRYLINE EXPECTED TO SET
UP ONCE AGAIN...FARTHER EAST THAN TODAY...WHICH WILL YIELD THE
THREAT OF SEVERE WEATHER ACROSS MOST OF OKLAHOMA AND WESTERN NORTH
TEXAS. THE AMOUNT OF CONVECTION THE NEXT TWO DAYS WILL PLAY A MAJOR
ROLE IN DETERMINING WHERE THE MAIN SURFACE BOUNDARY WILL SET UP LATE
MONDAY THROUGH TUESDAY. CONCENSUS OF MODELS IS THAT BOUNDARY SHOULD
BE LOCATED FROM SW TO NE ACROSS OUR FORECAST AREA...WHICH I CANT
ARGUE. THIS WILL NOT HAVE A SIGNIFICANT IMPACT ON TEMPS...BUT QPFS
WILL BE CRITICAL TOWARD MID WEEK.

WILL CONTINUE WITH CHANCE OF THUNDERSTORMS THROUGH THE EXTENDED
PERIODS...WITH POTENTIAL FOR STRONG CONVECTION ASSOCIATED WITH
DRYLINE EACH DAY.

WENT CLOSE TO MOS GUID ON TEMPS...AOA FAN GUID ON POPS.
