FORECAST CONCERNS THIS AFTERNOON...INCLUDE THE HIGH FIRE DANGER
THREAT THROUGH THE EARLY EVENING...FOLLOWED BY THE CHANCE FOR
MIXED PRECIPITATION STARTING LATE FRIDAY AND PERSISTING INTO
SUNDAY.

WINDS AND LOW HUMIDITY VALES WILL CONTINUE THIS AFTERNOON. A RED

A COLD FRONT WILL PUSH INTO THE AREA THIS EVENING...SHIFTING WINDS
OUT OF THE NORTHWEST AND LOWERING TEMPERATURES BACK NEAR NORMAL
FOR LATE JANUARY. WINDS WILL REMAIN STRONG BEHIND THE FRONT...WITH
GUSTS AGAIN REACHING BETWEEN 25 AND 30 MILES PER HOUR ACROSS
NORTHEAST OKLAHOMA TOMORROW AFTERNOON.

AN UPPER LEVEL LOW PRESSURE SYSTEM WILL DEVELOP AND DEEPEN OVER
THE SOUTHWEST US OVER THE NEXT COUPLE DAYS...DIRECTING MOISTURE
NORTHEAST INTO THE SOUTHERN PLAINS FOR THE END OF THE WEEK.
PRECIPITATION WILL SPREAD INTO THE SOUTHERN PLAINS STARTING
FRIDAY...MAINLY FALLING AS RAIN AS TEMPERATURES WILL REMAIN TOO

OVER TO ALL RAIN DURING THE DAY SATURDAY...WITH AMOUNTS RANGING
BETWEEN A HALF INCH TO AN INCH OF TOTAL LIQUID. AN UPPER LEVEL
WAVE AND COLD FRONT WILL THEN DROP INTO THE AREA EARLY

EAST BY THIS TIME...HOWEVER A SWITCH OVER TO A WINTRY MIX OF
RAIN...SLEET...AND SNOW WILL LIKELY OCCUR ON THE BACK SIDE OF THE
PRECIPITATION FIELD SUNDAY MORNING INTO EARLY SUNDAY AFTERNOON.

AND SLEET ACCUMULATIONS OCCURRING ACROSS NORTHEAST OKLAHOMA AND
NORTHWEST ARKANSAS. THE PRECIPITATION WILL COME TO AN END BY LATE
SUNDAY AFTERNOON...WITH A PERIOD OF DRY AND SEASONAL WEATHER
PERSISTING THROUGH THE REST OF THE FORECAST PERIOD.
