AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE NORMAN OK
340 PM CDT WED JUL 10 2002

MAIN CONVECTION THIS AFTERNOON HAS DEVELOP ALONG OUTFLOW BOUNDARY
ACROSS EASTERN SECTIONS OF KANSAS AND TO A LESSER DEGREE ALONG
PREFRONTAL TROUGH ACROSS SOUTHERN KANSAS.  EXPECT THAT STORMS
ONGOING ACROSS FA WILL QUICKLY DISSIPATE THIS EVENING AND THAT BEST
CHANCE OF STORMS DURING THE OVERNIGHT WILL BE ACROSS NORTH CENTRAL
OKLAHOMA AS STORMS FROM EASTERN KANSAS APPROACH THE AREA.

OUTFLOW BOUNDARIES FROM OVERNIGHT CONVECTION ALONG WITH COLD FRONT
SHOULD PRODUCE SCATTERED TSRA ON THURSDAY WITH BEST COVERAGE DURING
THE AFTERNOON ACROSS CENTRAL PARTS OF FA AND POINTS SOUTH DURING THE
OVERNIGHT HOURS.  WILL GO WARMER THAN GUIDANCE FOR POPS ON THURSDAY
AS TEMPS AHEAD OF FRONT SHOULD BE SIMILAR TO TEMPS ACROSS SOUTHERN
KANSAS THIS AFTERNOON.

WILL ALSO GO WARMER OR ABOVE FWC NUMBERS FOR FRIDAY AS MAV NUMBERS
APPEAR MUCH TO LOW.  MAIN RESULT FROM FRONT WILL BE TO USHER IN
DRIER AIRMASS WHICH WILL ALLOW FOR COOLER NIGHTS BUT NEARLY AVERAGE
DAYTIME HIGHS.

MEDIUM RANGE MODELS (ECMWF AND MRF) CONTINUE TO SHOW SHORT WAVE
CURRENTLY OVER NORTHERN PLAINS DROPPING SOUTH AND SOUTHEAST INTO
MISSOURI VALLEY AND THEN EVOLVING INTO SHEAR AXIS EXTENDING FROM
EAST TEXAS INTO ILL/IN BY START OF EXTENDING PERIOD.  BY EARLY NEXT
WEEK BOTH MODELS DEVELOP CLOSED LOW ANYWHERE FROM SE KANSAS TO NORTH
TEXAS WITH RIDGING TO THE WEST AND EAST.  WOULD IMAGE THAT MOST IF
NOT ALL WEATHER ASSOCIATED WITH THIS WILL BE EAST OF LOW/SHEAR
AXIS...SIMILAR TO WHAT HAPPENED LAST WEEK.  THEREFORE WILL LIKELY GO
WITH SLIGHT/CHANCE POPS EASTERN THIRD/HALF AND MAYBE KEEP WESTERN
PARTS DRY AND WARMER.  OVERALL THIS WILL RESULT IN MINOR CHANGES TO
CURRENT EXTENDED.  WILL SEND EXTENDED GRIDS SOON.
