AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE AMARILLO TX
655 AM CDT FRI APR 13 2007
.AVIATION...
MIXED PRECIPITATION OCCURRING ON RADAR ACROSS THE PANHANDLES. MOSTLY
SHOWERS AND THUNDERSTORMS IN THE EAST AND NORTHEAST PANHANDLES...WITH
PRECIP CHANGING OVER TO LIGHT SNOW IN THE NORTHWEST PANHANDLES. UPPER
LOW IS DIGGING FURTHER SOUTH THAN PREVIOUS MODELS INDICATED...WHICH
WILL LEAD TO THE SNOWFALL PUSHING FURTHER SOUTH ACROSS THE
PANHANDLES. TAFS INDICATE THE PRCIP CHANGE TO -SN IN DALHART AND
GUYMON IN A TEMPO GROUP THROUGH 16Z. THINKING THE PRECIP WILL THEN
BECOME PREDOMINANTLY -SN THROUGH THE REST OF THE DAY AS THE COLDER
AIR REACHES THE PANHANDLES. SNOW LINE WILL THEN REACH THE AMARILLO
AREA LATER THIS AFTERNOON AND EVENING...POSSIBLY AS EARLY AS 22Z BUT
MORE CONFIDENT ON THE -RASN BEGINNING CLOSER TO 00Z AS CURRENT TAFS
INDICATE. WINDS WILL ALSO BE AN ISSUE BEHIND THE FRONT AS NORTHERLY
FLOW WILL PICK UP INTO THE 18KT TO 25KT RANGE GUSTING TO AROUND 30KT.
THIS WILL LEAD TO AREAS OF BLSN AND REDUCED VIS. CIGS SHOULD STAY IN
THE LIFR TO IFR RANGE ACROSS THE PANHANDLES THROUGH MOST OF THE
DAY...WITH OCCASIONAL PERIODS OF VLIFR CONDITIONS WITHIN THE HEAVIER
SNOW BANDS. THINKING PRECIP WILL WIND DOWN AROUND 10Z TOMORROW WITH
THE CIGS SLOWLY LIFTING TOWARD THE MVFR RANGE.

.PREV DISCUSSION... /ISSUED 640 AM CDT FRI APR 13 2007/
DISCUSSION...
RUNNING WAY BEHIND DUE TO ACTIVE SVR WX EARLIER AND NOW MAJOR CHANGES
REQUIRED TO PREVIOUS PCKG DUE TO APCHG UPPER LOW...AND WHAT A MESS
IT IS. BOTTOM LINE...UPPER LOW WAS LOCATED OVER EXTRM SERN AZ AND
SWRN NM...EXTENDING INTO EXTRM NRN MEXICO...MUCH FURTHER S THAN ANY
MODEL HAD PROGGED YESTERDAY OR IN THE PAST FEW DAYS FOR THAT
MATTER. ALL SHORT RANGE MODELS INSIST IT WILL TAKE A SHARP NE TURN
TO CROSS ERN NM AND TX PNHDL LATER TODAY WHILE NGM ACTUALLY IS
FURTHER S WITH THE PATH. HAVE SOME CONCERN THE LOW MAY END UP A BIT
FURTHER S THAN 00Z MODELS PROG BASED ON CURRENT LOCATION.
NEVERTHELESS...THE FURTHER S LOCATION ALREADY SUGGESTS MORE OF THE
AREA WILL BE IN THE COLD AIR SECTOR WITH POTENTIAL FOR MORE
ACCUMULATING SNOWS THAN EARLIER PCKGS HAD...ESPECIALLY OK PNHDL AND
FAR NW TX PNHDL. LATEST DISCUSSION FROM HEAVY SNOW BRANCH AND
APPROPRIATE GRAPHICS BEAR THIS OUT...WITH OK AND PARTS OF NRN TX
PNHDL IN HIGH RISK OF GREATER THAN 4 INCH SNOWS...WITH MDT TO HIGH
RISK OF 8 INCH PLUS SNOWS AND LOW RISK OF 12 INCH PLUS ENDING 12Z
SAT. HAVE GONE WITH A WINTER STORM WARNING OK PNHDL AND NWRN TX
PNHDL TIL 11Z SAT...AND REPLACED SNOW ADVISORY WITH SNOW AND
BLOWING SNOW ADVISORY DUE TO BREEZY TO WINDY CONDITIONS...FOR MOST
OF NRN TX PNHDL AND PART OF WESTERN TEXAS PNHDL UNTIL 11Z SAT AS
WELL. IT MUST BE EMPHASIZED THAT IF THIS UPPER LOW CONTINUES ON A
MORE SRN TRACK..THEN MORE OF THE WESTERN...CNTRL..AND NERN TX PNHDL
WILL NEED TO BE CONSIDERED FOR HIGHLIGHTS...INCLUDING AMARILLO. THIS
WILL NEED TO BE CLOSELY MONITORED BY NEXT SHIFT AS PATH OF UPPER
LOW BECOMES MORE APPARENT AS IT APCHS SRN HIGH PLAINS.
RAPIDLY IMPROVING WX FROM SW TO NE LATER TNGT. DRY WX SAT THRU MON.
NEXT UPPER LOW SLATED FOR MON THRU TUE TIME FRAME...AND ALL MEDIUM
RANGE MODELS HAVE SPED UP THIS SYSTEM FOR EARLY NEXT WEEK...DUE TO
CLOSE PROXIMITY OF UPSTREAM KICKER. SO...WILL HAVE SLGT CHC POPS MON
NIGHT AND TUE...THEN DROP TO NON MENTIONABLE TUE NIGHT. DRY FOR WED
AND THU AT THIS TIME.
