AREA FORECAST DISCUSSION...UPDATED
NATIONAL WEATHER SERVICE AMARILLO TX
1132 PM CST FRI DEC 21 2007
.AVIATION...
LIGHT PRECIPITATION HAS COMMENCED AT KDHT AND KGUY THIS HOUR...BUT
HAS BEEN SLOW TO CHANGEOVER TO SNOW AT KGUY. THIS SHOULD OCCUR IN THE
NEXT HOUR OR SO AS THE COLD AIR DEEPENS AS STRONG COLD ADVECTION IS
UNDERWAY. THE COLD FRONT HAS PASSED ALL THREE TAF SITES AND NORTHERLY
WINDS WILL REMAIN IN THE 20 TO 30 KT RANGE...WITH GUSTS AROUND 35
KTS. AT THIS TIME I DO NOT HAVE THE CONFIDENCE TO HOIST AN AVIATION
WEATHER WARNING FOR GUSTS OF 40 KTS OR GREATER AT KAMA...BUT THIS
WILL BE MONITORED BY THE NEXT SHIFT. WINDS WILL DIMINISH A BIT DURING
THE AFTERNOON BEFORE DROPPING OFF QUICKLY BY 00Z. MVFR CIGS HAVE ALSO
DEVELOPED AT KDHT/KGUY AND ARE APPROACHING KAMA. VSBYS ARE EXPECTED
TO TEMPORARILY DROP TO IFR AT KDHT/KGUY BUT SHOULD REMAIN MVFR AT
KAMA.
WINTRY PRECIPITATION CONTINUES TO BE THE OTHER SIGNIFICANT AVIATION
HAZARD TONIGHT. AS THE SHORTWAVE TROF APPROACHES...INCREASING LIFT
WILL RESULT IN MORE WIDESPREAD AND MORE INTENSE SNOWFALL. IN
ADDITION...THE STRONG WINDS WILL RESULT IN BLOWING SNOW. THE FALLING
AND BLOWING SNOW WILL RESULT IN WIDESPREAD MVFR VSBYS...WITH TEMPO
VSBYS OF IFR CRITERION OR LOWER. CONDITIONS ARE EXPECTED TO IMPROVE
BY 14/15Z AS THE SHORTWAVE PASSES. SOME MVFR VSBYS /DUE TO BLOWING
SNOW/ AND CIGS ARE POSSIBLE THROUGH 17/18Z BEFORE VFR CONDITIONS
TAKE OVER.

UPDATE...
COLD FRONT HAS MOVED THRU OK PNHDL AND NRN TIER OF COUNTIES OF TX
PNHDL. CURRENT FCST HAS GOOD HANDLE ON TIMING OF FROPA...WITH NO
ADJUSTMENTS TO WIND GRIDS NECESSARY. LIGHT RAIN WAS REPORTED BY
COOPERATIVE OBSERVER IN GUY...BEGINNING ABOUT 0215Z...SHORTLY AFTER
KGUY ASOS DETECTED -RA. ECHOES SEEN ON KAMA 88D OVER OK PNHDL HAVE
BEEN DECREASING IN INTENSITY DURING THE PAST HOUR...AS SUPPORT FROM
LEAD SHORTWAVE TROF DIMINISHES. STRONGER SHORTWAVE IS EXPECTED TO
MOVE OUT OF NERN NM INTO NWRN AND N-CENTRAL ZONES DURING THE NEXT FEW
HOURS. AS THIS OCCURS...EXPECT SNOW TO DEVELOP AND SPREAD SEWD INTO
REMAINING SECTIONS. CONTINUE SNOW AND BLOWING SNOW ADZY.
COCKRELL
PREV DISCUSSION... /ISSUED 542 PM CST FRI DEC 21 2007/
AVIATION...
THE INTITIAL COLD FRONT IS PUSHING INTO THE OK PANHANDLE AT THIS
TIME. THIS FRONT WILL PUSH SOUTH THROUGH THE EVENING AND IS PROGGED
TO ARRIVE AT KDHT BETWEEN 01/02Z AND KAMA BETWEEN 03/04Z. THE
STRONGER WINDS ARE EXPECTED TO LAG BEHIND THE INITIAL WIND SHIFT BY
ABOUT 2 HOURS AND EVENTUALLY INCREASING TO 25 TO 30 KTS...WITH GUSTS
APPROACHING 40 KTS...AREAWIDE BEFORE MIDNIGHT. WIND SPEEDS ARE
EXPECTED TO REMAIN FAIRLY STRONG THROUGH 18Z ON SATURDAY...BEFORE
GRADUALLY DIMINISHING DURING THE AFTERNOON AS THE SURFACE GRADIENT
WEAKENS.
THE OTHER ISSUE WILL BE THE ONSET AND INTENSITY OF THE WINTRY PRECIP
TONIGHT. SOME LIGHT ECHOES CONTINUE TO APPEAR ON THE RADAR...BUT DUE
TO THE DRY LOW-LEVELS...MUCH OF THIS IS LIKELY EVAPORATING BEFORE
REACHING THE GROUND. THE COLUMN WILL QUICKLY MOISTEN OVERNIGHT AS THE
STRONG SHORTWAVE TROF APPROACHES. THIS WILL SUPPORT A RAPID
CHANGEOVER TO ALL SNOW AT KGUY/KDHT BY 03/04Z AND AT KAMA BY 06/07Z.
SNOW INTENSITY MAY BE MODERATE TO HEAVY AT TIMES...AND COMBINED WITH
THE VERY STRONG WINDS...VSBYS WILL BE QUITE THE PROBLEM. DUE TO THE
STRONG LIFT...I WOULD NOT COMPLETELY RULE OUT A STRAY LIGHTNING
STRIKE TONIGHT. THE LOWER VSBYS ARE EXPECTED IN THE NORTHERN AREAS
WHERE THE SNOW WILL LIKLEY BE MORE PREVALENT. SNOW WILL BEGIN TO
TAPER OFF BY 15Z OR SO ON SATURDAY...BUT BLOWING SNOW WILL CONTINUE
TO HINDER VSBYS THROUGHOUT MUCH OF THE DAY.
JOHNSON
PREV DISCUSSION... /ISSUED 319 PM CST FRI DEC 21 2007/
DISCUSSION...
WARM TEMPERATURES TODAY WILL DEPART RAPIDLY TNGT AS STRONG COLD FRONT
PASSES THROUGH. NLY SFC WINDS...COMBINED WITH LIFT AND COLD AIR ALOFT
FROM POTENT SHRTWV TROFS APPROACHING FROM THE W WILL HELP TO COOL THE
ATMOSPHERE QUICKLY...WITH ANY PRECIP CHANGING TO SNOW BY MIDNIGHT.
DYNAMIC LIFT WILL BE SUPPLEMENTED ACROSS NRN ZONES BY ISENTROPIC
LIFT. MODELS STILL APPEAR TO BE EXCESSIVE IN THEIR QPF FIELDS...AND
WILL CONTINUE WITH CONSERVATIVE SNOW AMT FCST. WILL NEED TO MONITOR
IN CASE UPGRADE TO WINTER STORM WARNING BECOMES NECESSARY. AT ANY
RATE...NEAR BLIZZARD CONDITIONS MAY ENSUE FOR BRIEF PERIODS TNGT AND
SAT MRNG WITH WIND GUSTS NEAR 50 MPH.
RAPID IMPROVEMENT EXPECTED AS UPR TROF EXITS SAT AFTN AND EVE. WINDS
WILL SUBSIDE AS SFC RIDGE MOVES IN...WITH COOL MINIMA TO RESULT EARLY
SUN.
NEXT UPR TROF WILL MOVE SE ACROSS THE FCST AREA SUN EVE AND MON.
GIVEN LACK OF MID AND UPR LVL MOISTURE...PASSAGE EXPECTED TO BE DRY.
STRONGER WAVE EXPECTED TUES AFTN AND EVE...WHICH WILL TAP MORE
MOISTURE AND MAY BRING LIMITED SNOW TO THE PANHANDLES TUES EVE. HAVE
REDUCED POPS TO SLGT CHC AREA WIDE GIVEN THAT BEST LIFT IS EXPECTED N
OF FCST AREA.
ANOTHER TROF DROPS SE WEDS THROUGH FRI. OPERATIONAL GFS CURRENTLY
MORE PROGRESSIVE THAN ENSEMBLES...AND SO HAVE OPTED FOR DRY FCST AT
THIS TIME UNTIL PARTICULARS CAN BE BETTER ASCERTAINED.
CONCERNING TEMPERATURES...PROGRESSIVE PATTERN EXPECTED TO ALLOW FOR
SERIES OF COLD FRONTS TO PASS THROUGH. THEREFORE...MEXMOS NUMBERS
SEEM REASONABLE /I.E. BLW AVG MAXIMA/ IN THE MEDIUM TO EXTENDED RANGE
AND WERE GENLY ACCEPTED.
