Area forecast discussion, Sep 30, 3:22 PM CDT, 5 hours 45 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE TULSA OK
322 PM CDT SUN SEP 30 2007

.DISCUSSION...
MUCH ADVERTISED COOL FRONT IS RAPIDLY APPROACHING THE AREA AND
EXTENDED FROM ABOUT WICHITA TO ENID TO GRANITE. SATELLITE
EXTRAPOLATION PLACES FRONT TO NEAR TULSA BY 00Z WITH A RAPID DROP
IN LOW LEVEL MOISTURE IMMEDIATELY BEHIND IT. NARROW LINE OF STRONG
STORMS HAS DEVELOPED ALONG THE FRONT FROM NE KANSAS BACK TO NEAR
I-35 CORRIDOR IN NC OKLAHOMA. ANALYSIS OF CONVECTIVE GRIDS SHOWS
FRONT WILL BE ENCOUNTERING A WEAKLY CAPPED AIRMASS NORTH OF I-40
THROUGH THE LATE AFTERNOON WITH SFC BASED CAPES 2000-2500 THROUGH
MUCH OF EASTERN OK.

BOUNDARY WILL EVENTUALLY BECOME MORE EAST-WEST ORIENTED LATER
TONIGHT AS UPPER SYSTEM LIFTS NE TOWARD THE GREAT LAKES. WILL SEE
A CONTINUED THREAT OF THUNDERSTORMS OVERNIGHT ACROSS SOUTHERN
SECTIONS BUT WITH A REDUCED SEVERE THREAT. DRY AIR AND CLEARING
SKIES WILL BRING COOLER OVERNIGHT LOWS TO NORTHERN SECTIONS...AND
GENERALLY UNDERCUT GUIDANCE LOW TEMPS A LITTLE OVER NE OKLAHOMA.

MODELS HAVE COME INTO SOMEWHAT BETTER AGREEMENT IN HANDLING THE
AIRMASS CHANGE MONDAY WITH MOISTURE LURKING NEAR THE RED RIVER AND
GRADUALLY SURGING NORTH AGAIN BY EARLY TUESDAY AS NEXT SYSTEM
APPROACHES IN PROGRESSIVE UPPER PATTERN. MOISTURE ASSOCIATED WITH
THIS SYSTEM APPEARS DEEPER AND THUS A BETTER OPPORTUNITY FOR SIG
RAINFALL LATE TUESDAY. AGAIN THOUGHT THE AIRMASS CHANGE IN THE
WAKE OF FRONT IS NOT GREAT AND WILL REMAIN WARM THROUGH THE
REMAINDER OF TE WEEK.

ALL MEDIUM RANGE PROGS INDICATE THE UPPER PATTERN BECOMES MORE
AMPLIFIED WITH TIME BY LATE IN THE WEEK. THIS WILL BRING THE FIRST
REAL COLD FRONT OF THE SEASON POSSIBLY AS EARLY AS SUNDAY AS A
STRONG TROUGH MOVES INTO THE PLAINS.
