.DISCUSSION...

A WEAK RIDGE OF HIGH PRESSURE OVER THE GULF OF MEXICO WILL INTERACT
WITH A DEEPENING LOW PRESSURE SYSTEM OVER WESTERN KANSAS TO KEEP A
STRONG PRESSURE GRADIENT OVER THE SOUTHERN PLAINS FOR THE NEXT 12
HOURS.  SUSTAINED WINDS MAY DIMINISH SLIGHTLY TO 20 MPH AFTER
SUNSET HOWEVER WIND GUSTS ARE EXPECTED TO CONTINUE TO RANGE FROM
35 TO 40 MPH THROUGH MIDNIGHT TONIGHT.  AFTER MIDNIGHT THE APPROACH
OF A WEAK UPPER LEVEL TROUGH MAY CAUSE THUNDERSTORMS TO DEVELOP
IN AND AROUND THE METROPLEX.  CHANCE OF PRECIPITATION OVERNIGHT IS
ABOUT 30 PERCENT.  THE APPROACH OF A COLD FRONT ON FRIDAY WILL
EVENTUALLY BRING SOME RELIEF FROM THE STRONG SOUTHERLY WINDS.
RELATIVE HUMIDITY VALUES ARE EXPECTED TO REMAIN AROUND 50 PERCENT
THIS AFTERNOON...SO ORGANIC MATERIALS ARE NOT EXPECTED TO BURN
EFFICIENTLY.  REGARDLESS STRONG SOUTHERLY WINDS THROUGH MIDNIGHT
LOOK TO PROVIDE CONDITIONS THAT WILL MAKE CONTROLLING THIS FIRE
DIFFICULT.
