A QLCS/SQUALL LINE CONTINUES TO MOVE QUICKLY S/SEWRD ACROSS OKLAHOMA
THIS MORNING...AND CONTINUES TO BE THE MAIN FORECAST CONCERN. ON ITS
PRESENT TIMING/TRACK...THE QLCS WILL REACH THE OKC METRO BETWEEN
0230 AND 0300 AM CDT. THE OVERALL LINE OF CONVECTION IS FAIRLY
VAST...EXTENDING FROM JUST S OF AMARILLO OFF THE CAPROCK...EWD TO I-
40 ALONG THE OK/TX BORDER...NE THROUGH PONCA CITY...AND N INTO SRN
KS. MESONET OBS ALONG THE PATH HAVE CONTINUED TO REPORT 45 TO 55 MPH
WINDS ALONG THE LINE...HOWEVER...WINDS IN EXCESS OF 60 MPH ARE
POSSIBLE...AND CONTINUE TO BE THE PRIMARY HAZARD. GIVEN ITS
OVERNIGHT HOURS...REPORTS HAVE BEEN SPARSE...BUT THERE WAS A REPORT
OF POWERLINES KNOCKED DOWN IN THE TOWN JET IN ALFALFA COUNTY AS THE

MAINTENANCE...WITH GOOD SHEAR/COLD POOL BALANCE WITH 0-3KM SHEAR 0F
20 TO 35 KTS AND MUCAPES 1900 TO 2800 J/KG. THE N/NERN PORTION OF
THE LINE AS IT MOVES THROUGH CENTRAL OK WILL BE THE SECTION TO WATCH
AS CONDITIONS WILL BE MOST FAVORABLE FOR WINDS GREATER THAN 60 MPH.
SFC-600MB THETA E DIFFS WILL BE 20 TO 25 K...WITH THE BEST POCKET OF
MUCAPES RESIDING SWRN THROUGH CENTRAL OK.

AS THE LINE APPROACHES THE RED RIVER VALLEY THROUGH DAWN...IT WILL
BEGIN TO MOVE INTO A LESS FAVORABLE ENVIRONMENT. HOWEVER...RAIN AND
GUSTY WINDS WILL CONTINUE.

THUNDERSTORM CHANCES WILL CONTINUE THROUGH THIS AFTERNOON AS A SFC
FRONTAL BOUNDARY STALLS FROM THE TX PANHANDLE THROUGH SOUTHERN OK.
