AVIATION...
FOR THE 00Z TAFS...GRADUALLY DETERIORATING WEATHER CONDITIONS
EXPECTED AT ALL TERMINAL SITES DURING THIS FCST CYCLE AS AN UPPER

AT KGUY AND KDHT NEAR 07Z SUNDAY...SPREADING SWD TO INCLUDE KAMA BY
12Z SUNDAY. THE PRECIPITATION SHOULD DIMINISH FROM NORTH TO SOUTH

PREV DISCUSSION... /ISSUED 341 PM CST SAT FEB 21 2015/
SHORT TERM...
STILL LOOKS LIKE TWO SEPARATE CHANCES FOR ACCUMULATING SNOW ACROSS
THE PANHANDLES FROM TONIGHT THROUGH MONDAY AFTERNOON. THE FIRST
CHANCE BEGINS TONIGHT WITH A COLD FRONT MOVING INTO THE OKLAHOMA
PANHANDLE. PRECIPITATION MAY BEGIN AS A RAIN/SNOW MIX...BUT IS
EXPECTED TO CHANGE OVER TO ALL SNOW FAIRLY QUICKLY FROM NORTH TO
SOUTH LATE TONIGHT. HI-RES MODELS CONTINUE TO DEPICT THE POSSIBILITY OF
MESOSCALE BANDING DEVELOPING ACROSS THE OKLAHOMA PANHANDLE BETWEEN
MIDNIGHT AND 6 AM WITH FAIRLY STRONG FRONTOGENETICAL FORCING IN THAT
AREA. BANDS WILL DRIFT SOUTH INTO THE NORTHERN TEXAS PANHANDLE...WITH
HIGHEST AMOUNTS GENERALLY NORTH OF A DALHART TO CANADIAN LINE.
PORTIONS OF THE OKLAHOMA PANHANDLE AND NORTHERN TEXAS PANHANDLE
COULD QUICKLY PICKUP 4 TO 6 INCHES DURING THIS FIRST BURST OF SNOW.
HAVE EXTENDED THE WINTER STORM WARNING TO THE FIRST TIER OF COUNTIES
IN THE NORTHWEST TEXAS PANHANDLE....BUT IF TRENDS IN THE MESOSCALE
BANDING CONTINUE TO PUSH FURTHER EAST...EASTERN COUNTIES MAY ALSO
NEED TO BE UPGRADED FROM ADVISORY TO WARNING AS WELL. HEAVIER SNOW
WILL DRIFT SOUTH AND DISSIPATE SOME THROUGH THE MORNING.THE BANDING
APPEARS TO LOSE ITS STRUCTURE AS IT DRIFTS FURTHER SOUTH...BUT A WEAK
SHORTWAVE SHOULD ALLOW FOR PERIODS OF LIGHT SNOW ACCUMULATION ACROSS
THE PANHANDLES THROUGH THE DAY SUNDAY. AS A RESULT...HAVE DECREASED POPS FOR
MUCH OF THE DAY ON SUNDAY TO JUST CHANCE.
THE NEXT OPPORTUNITY FOR PERIODS OF HEAVIER SNOW ACCUMULATIONS BEGIN
LATE SUNDAY NIGHT AND INTO EARLY MONDAY MORNING AS A SHORTWAVE EJECTS
OUT OF A DEVELOPING CUTOFF LOW OVER THE GREAT BASIN AND COLDER AIR
CONTINUES TO FILTER INTO THE PANHANDLES FROM AN ARCTIC AIRMASS OVER
THE CENTRAL PLAINS. HOWEVER...AS GREATER FORCING SHIFTS
EASTWARD...THERE IS A POTENTIAL FOR PORTIONS OF THE PANHANDLES TO BE
CUTOFF FROM THE BULK OF THE PRECIPITATION. HAVE KEPT HIGHEST POPS AND
AMOUNTS CONFINED TO THE SOUTHERN TEXAS PANHANDLE FOR NOW ON MONDAY
MORNING...WITH SNOW TAPERING OFF BY EARLY AFTERNOON.
ELSENHEIMER
LONG TERM...
MONDAY NIGHT THROUGH FRIDAY...
THE COLD SURFACE RIDGE WILL MOVE OFF TO THE EAST MONDAY NIGHT AND
TUESDAY AS ZONAL UPPER FLOW ALLOWS FOR DECREASING CLOUDINESS AND
DRIER CONDITIONS BRIEFLY. MODERATING CONDITIONS TUESDAY AND
WEDNESDAY. SURFACE TROUGH WILL PUSH ACROSS THE PANHANDLES LATE
TUESDAY SHIFTING THE WINDS AROUND TO THE NORTH AND NORTHWEST...THEN
WINDS BACKING AROUND TO THE WEST AND SOUTHWEST WEDNESDAY. BACKDOOR
COLD FRONT ARRIVES IN THE FORECAST AREA LATE WEDNESDAY OR WEDNESDAY
EVENING FROM NORTHEAST TO SOUTHWEST WITH WINDS SHIFTING TO THE EAST
BY WEDNESDAY NIGHT. MUCH COLDER AIR BEHIND THE FRONT ALONG WITH
GOOD ISENTROPIC LIFT WEDNESDAY NIGHT INTO LATE NEXT WEEK AND A FEW
UPPER TROUGHS APPROACHING THE PANHANDLES FROM THE WEST DURING THE
LATTER HALF OF NEXT WEEK WITH BRING GOOD CHANCES FOR MORE SNOW
ACROSS THE PANHANDLES.
