AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE NORMAN OKLAHOMA
254 PM CDT WED JUL 9 2003

COLD FRONT CONTINUES TO MOVE ACROSS THE PLAINS TODAY...WITH SHOWERS
AND THUNDERSTORMS BEGINNING TO DEVELOP ALONG THE FRONT IN CENTRAL
KANSAS THIS AFTN. THE FRONT WAS LOCATED ACROSS CENTRAL KANSAS...TO
EASTERN OKLAHOMA PANHANDLE...INTO THE TEXAS PANHANDLE. THE COLD
FRONT WILL MOVE INTO NORTHWEST OK IN THE NEXT FEW HOURS AND CONTINUE
TO MOVE THRU PORTIONS OF THE FA OVERNIGHT. THE FRONT AND A SHORTWAVE
MOVING ACROSS THE CENTRAL U.S. SHOULD PROVIDE ENOUGH LIFT OF THE
MOIST AIRMASS THAT IS AHEAD OF THE FRONT FOR THUNDERSTORMS TO
DEVELOP THIS EVENING AND AFFECT THE AREA THRU THE DAY THURS. THE
BEST CHANCES TONIGHT WILL BE ACROSS EASTERN PORTIONS OF FA. A FEW
SEVERE THUNDERSTORMS ARE POSSIBLE THIS EVENING. DRIER AIR WILL MOVE
INTO THE AREA BEHIND THE FRONT WHICH COULD CAUSE LOWS TONIGHT TO BE
COOLER...ESPECIALLY ACROSS NORTHWEST ZONES.

THERE IS A CHANCE OF SHOWERS AND THUNDERSTORMS FRIDAY AND SATURDAY
NIGHT AS UPSLOPE FLOW CAUSES THUNDERSTORMS TO DEVELOP IN THE HIGH
PLAINS AND WITH NORTHWEST FLOW ALOFT...MOVE INTO THE FA AS AN MCS.
MODELS PROG THE RIDGE BUILDING BACK INTO THE AREA EARLY NEXT WEEK.
DUE TO THE RIDGE...CONDITIONS ARE EXPECTED TO REMAIN DRY UNTIL
MIDDLE OF NEXT WEEK WHEN ANOTHER FRONT IS EXPECTED TO MOVE ACROSS
THE PLAINS BRINGING ANOTHER CHANCE OF THUNDERSTORMS TO PORTIONS OF
THE AREA...WITH THE BEST CHANCES ACROSS NORTHEAST ZONES.

60 MPH. THUNDERSTORM MOTION WILL BE SOUTH SOUTHEAST AT 25 MPH.
