AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE NORMAN OK
525 PM CST TUE DEC 15 2009

.AVIATION...SKIES WILL REMAIN CLEAR EXCEPT FOR A FEW CIRRUS...
MAINLY IN NORTHWEST OKLAHOMA LATE WEDNESDAY. THIS EVENING A BROAD
PRESSURE RIDGE WILL BUILD DOWN THE INTERSTATE 44 CORRIDOR...
RESULTING IN LIGHT OR CALM WINDS AT SEVERAL TAF SITES THROUGH
EARLY WEDNESDAY. THE RIDGE WILL THEN DRIFT TO THE EAST...AND A
WEAK LEE TROUGH WILL PROMOTE DEVELOPMENT OF SOUTHERLY WINDS...
GUSTIEST IN WESTERN OKLAHOMA.

.PREV DISCUSSION... /ISSUED 322 PM CST TUE DEC 15 2009/ 

DISCUSSION...
THE SURFACE HIGH PRESSURE SYSTEM THAT BROUGHT THE CURRENT CHILLY
WEATHER TO THE SOUTHERN PLAINS WILL MOVE OFF TO THE EAST LATER
TONIGHT... AND DURING THE NEXT COUPLE OF DAYS. THIS WILL CAUSE
WINDS TO SWITCH TO SOUTHERLY DIRECTIONS AND WILL BRING MILDER
WEATHER BACK INTO OUR FORECAST AREA.

THE NEXT SIGNIFICANT WEATHER FEATURE SHOULD BE A SMALL MID-LEVEL
WAVE THAT WILL BRING A SLIGHT CHANCE OF LIGHT RAIN OR SNOW TO THE
NORTHEAST QUARTER OR SO OF OUR FORECAST AREA FRIDAY AFTERNOON AND
NIGHT. NO SIGNIFICANT RAIN OR SNOWFALL IS EXPECTED FROM THIS
SYSTEM.

SOMEWHAT COOLER WEATHER WILL THEN RETURN FOR THE WEEKEND AND EARLY
NEXT WEEK AS SEVERAL COLD FRONTS MOVE SOUTH ACROSS OKLAHOMA AND
NORTH TEXAS. MODEL GUIDANCE BECOMES INCREASINGLY UNRELIABLE AS THE
WEEK PROGRESSES... AND IT IS DIFFICULT TO DRAW MANY CONSISTENT
CONCLUSIONS FROM GUIDANCE AFTER THE WEEKEND. HOWEVER... THE ONE
THING THAT HAS REMAINED FAIRLY CONSISTENT IS THE MESSAGE OF A
COLDER-THAN-AVERAGE WEEK AHEAD OF... AND INCLUDING... CHRISTMAS
DAY. WHETHER OR NOT THERE WILL BE ANY KIND OF MEANINGFUL
PRECIPITATION IS VERY DIFFICULT TO SAY... GIVEN THE RUN-TO-RUN AND
MODEL-TO-MODEL DIFFERENCES.
