AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE NORMAN OK

.DISCUSSION...
THE BLIZZARD-GENERATING STORM SYSTEM WHOSE SURFACE CENTER IS NOW
OVER ARKANSAS WILL CONTINUE TO MOVE NORTHEAST OVERNIGHT...
GRADUALLY RELEASING ITS GRIP ON OKLAHOMA AND NORTH TEXAS. THE
ENHANCED SNOW BAND THAT HAS BROUGHT THE HEAVIEST SNOW ALONG AN
AXIS FROM STILLWATER TO OK CITY TO DUNCAN AND WICHITA FALLS WILL
GRADUALLY WEAKEN AND SHIFT EAST. IT APPEARS THAT IT WILL STILL BE
CAPABLE OF PUTTING DOWN SEVERAL MORE INCHES OF SNOW OVER OUR
EASTERN COUNTIES... ROUGHLY FROM I-35 ON EAST... WITH LESSER
AMOUNTS OVER OUR SOUTHEAST COUNTIES.

GIVEN THE CURRENT PROGRESS OF THE STORM SYSTEM... AND THE
CONTINUING STRONG PRESSURE GRADIENT BEHIND IT... HAVE OPTED TO
EXTEND THE BLIZZARD WARNING/WINTER STORM WARNING A FEW MORE HOURS
ALONG OUR EASTERN PERIPHERY.

WIND CHILLS REACH BORDERLINE LEVELS FOR AN ADVISORY LATE TONIGHT...
BUT GIVEN THE BIGGER-FISH-TO-FRY SITUATION... WILL NOT WORRY TOO
MUCH ABOUT THAT YET.

TEMPERATURES WILL BE HELD DOWN QUITE DRAMATICALLY BY THE NEW SNOW
COVER... AND THE NAM12 NUMBERS LOOK MORE REASONABLE THAN THOSE
FROM THE VARIOUS MOS GUIDANCE SOURCES FOR THE NEXT DAY OR TWO.
HAVE ONLY MADE CHANGES TO THE FIRST COUPLE OF PERIODS...
HOWEVER... DUE TO THE OVERALL WORKLOAD WITH THIS STORM. LATER
SHIFTS CAN FINE-TUNE THE NUMBERS AS NEEDED.
