AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE NORMAN OK
759 PM CDT THU OCT 4 2001

A FULL ZONE UPDATE PACKAGE WAS ISSUED ABOUT 2 HOURS AGO TO BRING SKY
CONDITION AND WIND INTO AGREEMENT WITH CURRENT OBSERVATIONS. COLD
FRONT IS FINALLY GETTING AN ASSIST FROM TSTORM OUTFLOW OVR NRN
OK..WITH NORTH WINDS NOW AT BOTH BUFFALO AND MAY RANCH MESONET SITES.
STORMS HAVE SO FAR HAD A HARD TIME BUILDING SWD INTO OKLAHOMA..BUT
BELIEVE CURRENT DOWNTREND IS TEMPORARY.  AREA PROFILERS/VAD WINDS
ALREADY INDICATE A 25 TO 30 KT LLJ IS IN PLACE..AND EXPECT THIS TO
INCREASE BETWEEN NOW AND 6-8Z.  LATEST RUC GUIDANCE SUGGESTS THAT
LLJ WILL INCREASE TO AOA 40 KTS AT 850 MB BY 6Z WITH PLUS 12 TO 14C
850 MB DEWPOINTS ALONG AND JUST NORTH OF THE SFC FRONT.  INCREASING
LOW LEVEL LIFT FROM INTENSE WAA SHUD BE MORE THAN SUFFICIENT TO
INCREASE RAIN/STORM COVERAGE AS WE APPROACH MIDNITE AND AFTER.
ELEVATED NATURE OF STORMS JUST NORTH OF SFC FRONT SHUD LIMIT ANY SVR
THREAT TO HAIL OVERNITE.  ADDITIONAL UPDATES WBIS AS NEEDED TO
ACCOUNT FOR FRONTAL MOVEMENT THRU THE REST OF THE NITE.
