DISCUSSION...
SURFACE TROUGH/WIND SHIFT LOCATED ACROSS FAR NORTHWEST OKLAHOMA
WILL NOT MAKE MUCH MORE PROGRESS TO THE SOUTH THIS AFTERNOON.
PRESSURE FALLS ASSOCIATED WITH APPROACHING SYSTEM JUST OFF
SOUTHERN CALIFORNIA WILL KEEP WINDS UP TONIGHT. THIS ALONG WITH
CIRRUS...AND MID LEVEL CLOUDS WILL RESULT IN VERY MILD TEMPS
OVERNIGHT.
CHANCES FOR RAIN OR STORMS STILL APPEAR MINIMAL FOR TONIGHT INTO
SATURDAY. DRYLINE/PACIFIC FRONT WILL PUSH INTO WESTERN/CENTRAL
SECTIONS OF FA SATURDAY. HOT DRY AIR BEHIND BOUNDARY AND STRONG
GUSTY WINDS WILL CREATE VERY HIGH TO EXTREME FIRE WEATHER CONDITIONS.

CORRIDOR. MORE EXTREME CONDITIONS ARE EXPECTED TO BE ACROSS
WESTERN OKLAHOMA AND WESTERN NORTH TEXAS. WIND GUSTS WITH THIS
SYSTEM APPEAR TO BE ON THE LOWER SIDE COMPARED WITH LAST TWO
EVENTS WHEN FREQUENT WIND GUSTS WERE OVER 50 MPH.
COLD FRONT IS FORECAST TO STALL ACROSS SOUTHEAST OKLAHOMA ON SUNDAY
BEFORE LIFTING NORTHWARD MONDAY AS NEXT PACIFIC SYSTEM MOVES ACROSS
CENTRAL AND NORTHERN ROCKIES. THIS SYSTEM WILL HELP PUSH ANOTHER
COLD FRONT ACROSS THE SOUTHERN PLAINS ON TUESDAY AND HELP COOL
TEMPERATURES BACK TO NEAR NORMAL. REINFORCING COOL FRONT MAY PUSH
INTO AREA ON THURSDAY. GFS INDICATES SOME PRECIPITATION WILL
BE POSSIBLE WITH THIS SYSTEM...ESPECIALLY SOUTHERN LOCATIONS. FOR
NOW WILL LEAVE EXTENDED PERIOD DRY.
