AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE TULSA OK
1028 AM CDT MON JUN 12 2006

.UPDATE...
WILL SEND A QUICK UPDATE TO POP FORECAST TO REFLECT CURRENT
TRENDS. ELEVATED THUNDERSTORMS CONTINUE TO DECREASE ACROSS
NORTHEAST OKLAHOMA...WHILE ANOTHER LINE OF STORMS CONTINUES TO
MOVE ACROSS WESTERN/CENTRAL OK. THIS LINE OF STORMS IS EXPECTED TO
GRADUALLY WEAKEN THE REMAINDER OF THE MORNING HOURS AS LOW LEVEL
JET SUPPORT DECREASES...BUT WILL LIKELY IMPACT MUCH OF THE AREA
WEST OF TULSA BEFORE DOING SO.

SYNOPTIC FRONT NEAR I-40 ALONG WITH OUTFLOW FROM MORNING ACTIVITY
MAY SERVE AS FOCUS FOR ADDITIONAL STORMS DURING THE AFTERNOON.
SKIES REMAIN CLEAR TO THE SOUTH AND THIS SHOULD ALLOW SUFFICIENT
INSTABILITY FOR ANY STORMS THAT DO DEVELOP TO BE SEVERE. FORECAST
HIGH TEMPS APPEAR REASONABLE THOUGH A FEW LOCATIONS MAY ULTIMATELY
NEED TO BE LOWERED. UPDATED PRODUCTS WILL BE OUT SHORTLY.
