AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE TULSA OK
1020 AM CST TUE DEC 23 2014

...UPDATE...

.DISCUSSION...
AT MID MORNING A LONGWAVE TROF AXIS WAS POSITIONED FROM THE TEXAS
PANHANDLE NORTHEASTWARD TO NORTHERN MICHIGAN...PER LATEST WATER
VAPOR IMAGERY. TO THE SOUTH AND EAST OF THIS TROF AXIS...UPPER
LEVEL WEST SOUTHWESTERLY FLOW WAS STREAMING CLOUD COVER OVER
EASTERN OKLAHOMA AND WESTERN ARKANSAS. WITHIN THIS FLOW...SOME
LIGHT RAIN SHOWERS HAD DEVELOPED WITHIN AN AREA OF WARM AIR
ADVECTION OVER SOUTHEAST OKLAHOMA AND WEST CENTRAL ARKANSAS THIS
MORNING BEHIND A SURFACE BOUNDARY WHICH MOVED THROUGH YESTERDAY.

LIGHT RAIN/AREAS OF DRIZZLE WILL REMAIN POSSIBLE OVER FAR
SOUTHEAST OKLAHOMA INTO WEST CENTRAL ARKANSAS THIS AFTERNOON
BEFORE THE SURFACE BOUNDARY PUSHES OUT OF THE SOUTHERN PLAINS.
CLOUD COVER IS EXPECTED TO REMAIN OVER THE CWA TODAY AS THE TROF
AXIS MAKES ITS WAY INTO THE REGION. THESE CONDITIONS SHOULD KEEP
AFTERNOON TEMPS SOMEWHAT IN CHECK WITH MOST LOCATIONS REMAINING IN
THE 40S.

THE TROF AXIS IS FORECAST TO PUSH INTO THE CWA THIS EVENING AND
OVERNIGHT TONIGHT. PRECIP CHANCES WILL BECOME POSSIBLE OVERNIGHT
ONCE THE AXIS MOVES IN. NORTHERLY FLOW AND COLDER TEMPS IN THE
WAKE OF THE TROF AXIS WILL ALLOW FOR PRECIP TO POTENTIALLY CHANGE
OVER TO LIGHT SNOW LATE TONIGHT INTO WEDNESDAY MORNING. AT THIS
TIME...ANY ACCUMULATIONS CONTINUE TO LOOK LIKE LESS THAN ONE
INCH...WITH THE HIGHER ACCUMULATIONS OVER THE HIGHER TERRAIN
LOCATIONS OF NORTHWEST ARKANSAS.

MORNING UPDATE WILL BE TO ADJUST AFTERNOON POP/SKY/WIND/TEMP GRIDS
BASED ON THE MENTIONED ABOVE. OTHERWISE...THE REST OF THE
FORECAST SEEMS IN GOOD SHAPE AT THIS TIME.
