LOCATIONS ARE FORECASTED NEAR OR BREAKING RECORD HIGHS AGAIN

HUMIDITIES...AND SOMEWHAT BREEZY WINDS WILL COMBINE TO ELEVATE THE
FIRE DANGER TO VERY HIGH THIS AFTN. CURRENTLY DO NOT HAVE AN AREA
FORECASTED WITH RED FLAG CRITERIA BUT A FEW LOCATIONS WILL BE
CLOSE... WITH THE BEST CHANCE IN PARTS OF CENTRAL OK. THIS IS
WHERE WIND SPEEDS HAVE THE BEST CHANCE OF MEETING CRITERIA FOR A
FEW HOURS BUT RIGHT NOW MIN RH VALUES ARE EXPECTED TO REMAIN ABOVE

THIS MORNING THEN DECREASE AROUND SUNSET. A COLD FRONT WILL MOVE
THROUGH THE AREA BRINGING MODERATE NORTH WINDS.

DISCUSSION...
ANOTHER HOT DAY TODAY WITH FORECAST MAX TEMPERATURES ROUGHLY 25 TO
30 DEGREES ABOVE AVERAGE. WIND WILL PICK UP THIS AFTERNOON AS WELL
/ESPECIALLY IN THE CENTRAL AND EAST/ WHICH WILL CREATE ELEVATED
FIRE WEATHER CONCERNS AGAIN TODAY. WE ARE CURRENTLY FORECASTING
HUMIDITY TO REMAIN ABOVE 20 PERCENT SO WILL NOT ISSUE FIRE WEATHER
HEADLINES... BUT WILL HIGHLIGHT THE CONCERN IN FWF AND OTHER
PRODUCTS.

A COLD FRONT MOVES THROUGH THE AREA TONIGHT BRINGING A RETURN TO
JANUARY. AN APPROACHING STORM SYSTEM WILL GIVE US HIGH CHANCES OF
PRECIPITATION FRIDAY INTO SUNDAY. TEMPERATURES WILL NOT BE TOO
COLD WITH THIS SYSTEM... BUT MAY DROP ENOUGH IN DIURNALLY COOL
TIMES OF NIGHT TO MIX WITH OR CHANGE TO SNOW IN THE NORTH. OVERALL
THERE WERE NO BIG CHANGES TO THE FORECAST PHILOSOPHY THIS MORNING.
