AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE NORMAN OK
312 AM CDT WED JUN 18 2008

.DISCUSSION...
THE PRESENT MCS MOVING INTO SOUTHERN KANSAS IS EXPECTED TO BRING
THE POTENTIAL FOR DAMAGING WINDS TO NORTHERN OKLAHOMA AROUND
SUNRISE. THIS COMPLEX WILL PROBABLY MOVE THROUGH CENTRAL OKLAHOMA
BEFORE 10 AM. AS YESTERDAY RESIDUAL BOUNDARIES WILL LIKELY BE THE
FOCUS OF ISOLATED THUNDERSTORMS THIS AFTERNOON IN WESTERN
OKLAHOMA. OVERNIGHT TONIGHT ANOTHER COMPLEX THAT DEVELOPS IN THE
WESTERN HIGH PLAINS WILL LIKELY AFFECT WESTERN AND CENTRAL
OKLAHOMA. LITTLE CHANGES FROM PAST CONDITIONS, OTHER THAN MINOR
CHANGES IN THE MOIST AXIS AND NOCTURNAL LOW-LEVEL JET, THROUGH
FRIDAY. ALTHOUGH MODEL CONFIDENCE IN MCS EVENTS FOR THE WEEKEND
ARE NOT HIGH, LITTLE CHANGES IN THE PATTERN THROUGH THAT TIME.
THE GFS IS AGAIN HOLDING ONTO MONDAY AS THE DAY THE UPPER RIDGE
SHIFTS SUFFICIENTLY EAST TO DIMINISH CHANCES FOR RAIN. QPF FOR
TODAY WERE TAKEN FROM HPC SINCE THE GFS DID NOT REPRESENT WELL THE
CURRENT MCS IN KANSAS.
