From National Weather Service, Amarillo, Texas, snow possible Tuesday and Wednesday
…SNOW POSSIBLE TUESDAY AND WEDNESDAY…
A STRONG LOW PRESSURE SYSTEM WILL TRAVERSE NORTHERN MEXICO TONIGHT…
THEN SLOWLY MOVE ACROSS WESTERN AND CENTRAL TEXAS TUESDAY AND
WEDNESDAY. PRECIPITATION MAY BEGIN AS EARLY AS TUESDAY MORNING
ACROSS THE SOUTHERN TEXAS PANHANDLE…BUT IS EXPECTED TO INCREASE IN
COVERAGE AND SPREAD NORTHWARD DURING THE AFTERNOON AND EVENING
HOURS. PRECIPITATION TYPE MAY BEGIN AS A MIXTURE OF LIGHT RAIN…
SNOW OR SLEET…BUT SHOULD QUICKLY CHANGE OVER TO ALL SNOW FOR
LOCATIONS ON THE CAPROCK. OFF THE CAPROCK…THE PRECIPITATION TYPE
SHOULD PERSIST AS RAIN THROUGH MOST OF THE DAY BEFORE CHANGING OVER
TO SNOW DURING THE EVENING HOURS.
A STRONG COLD FRONT WILL PUSH THROUGH THE TEXAS AND OKLAHOMA
PANHANDLES ON TUESDAY NIGHT…USHERING IN STRONG NORTH WINDS OF 20
TO 30 MPH…WITH HIGHER GUSTS. THIS MAY RESULT IN BLOWING AND
DRIFTING SNOW AS WELL AS DANGEROUS TRAVEL CONDITIONS. SNOW IS
FORECAST TO TAPER OFF FROM WEST TO EAST ON WEDNESDAY AS THIS UPPER
LOW MOVES OFF TO THE EAST. TOTAL SNOW ACCUMULATIONS OF 1 TO 3
INCHES ARE EXPECTED…MAINLY ACROSS THE SOUTHEAST HALF OF THE TEXAS
PANHANDLE. AMOUNTS OF LESS THAN 1 INCH ARE EXPECTED ELSEWHERE.
ANOTHER SYSTEM IS EXPECTED TO BRING LIGHT SNOW TO THE AREA WEDNESDAY
NIGHT AND THURSDAY…MAINLY IMPACTING THE WESTERN PORTIONS OF THE
TEXAS AND OKLAHOMA PANHANDLES. AT THIS TIME…ADDITIONAL SNOWFALL
AMOUNTS ARE FORECAST TO REMAIN BELOW 1 INCH.
PLEASE STAY TUNED TO NOAA WEATHER RADIO…OR THE NATIONAL WEATHER
SERVICE WEB SITE AT WWW.SRH.NOAA.GOV/AMA FOR THE LATEST WEATHER
FORECAST.
Looking ahead, Tuesday night, western portions of Oklahoma and Wednesday, for portions of southern Oklahoma
A MIX OF RAIN AND WET SNOW WILL BE POSSIBLE OVER THE WESTERN
PORTIONS OF OKLAHOMA AND NORTH TEXAS LATE TUESDAY NIGHT AND ACROSS
SOUTHERN OKLAHOMA AND NORTH TEXAS WEDNESDAY MORNING. HOWEVER…
LITTLE ACCUMULATION IS EXPECTED.
National Weather Service, Amarillo, Texas: Winter weather impact statement
PUBLIC INFORMATION STATEMENT
NATIONAL WEATHER SERVICE AMARILLO TEXAS
MON NOV 30 2009
…WINTER WEATHER IMPACT STATEMENT…
VALID THROUGH:
WEDNESDAY DECEMBER 2 2009
WINTER WEATHER EXPECTED:
MAINLY SNOW ON TUESDAY NIGHT THROUGH WEDNESDAY…ALTHOUGH A WINTRY
MIX OF RAIN…SNOW AND SLEET MAY BE POSSIBLY TUESDAY MORNING.
AFFECTED AREA:
THE MAIN AREA OF CONCERN IS THE SOUTHERN TWO ROWS OF THE TEXAS
PANHANDLE OR AREAS SOUTH OF THE CANADIAN RIVER VALLEY. LIGHTER SNOW
ACCUMULATIONS MAY OCCUR NORTH OF THE CANADIAN RIVER THOUGH.
FORECAST TIMING OF EVENT:
A LIGHT MIX OF RAIN…SLEET AND SNOW MAY DEVELOP TUESDAY MORNING
MAINLY ACROSS THE SOUTHWEST TEXAS PANHANDLE. LIGHT RAIN IS EXPECTED
ACROSS THE SOUTHEAST TEXAS PANHANDLE TUESDAY MORNING. DURING THE DAY
ON TUESDAY THE PRECIPITATION IS EXPECTED TO BECOME LIGHT RAIN.
HOWEVER…COLD AIR SHOULD MOVE INTO THE PANHANDLES TUESDAY NIGHT AND
BRING A TRANSITION TO SNOW. THE SNOW SHOULD DISSIPATE FROM WEST TO
EAST STARTING WEDNESDAY WITH THE SOUTHEAST TEXAS PANHANDLE SEEING THE
LAST FEW SNOW FLAKES WEDNESDAY AFTERNOON.
POTENTIAL IMPACTS:
ON TUESDAY MORNING…ANY PRECIPITATION IS EXPECTED TO BE LIGHT WITH
VERY LITTLE SNOW OR SLEET ACCUMULATIONS. SNOW ACCUMULATIONS OF 1 TO
3 INCHES ARE POSSIBLE FROM TUESDAY NIGHT THROUGH WEDNESDAY MAINLY
ACROSS THE SOUTHERN HALF OF THE TEXAS PANHANDLE. IN ADDITION…NORTH
WINDS OF 15 TO 25 MPH WITH GUSTS NEAR 30 MPH ARE EXPECTED ON
WEDNESDAY. THIS MAY CREATE AREAS OF BLOWING SNOW WHICH MAY CAUSE
VISIBILITY RESTRICTIONS AND POOR DRIVING CONDITIONS.
THIS AMOUNT OF SNOW MAY ALSO CREATE SLICK ROADWAYS ESPECIALLY ON
BRIDGES AND OVERPASSES. US HIGHWAY 60…INTERSTATE 40 AND INTERSTATE
27 WILL BR THE PRIMARY AREAS OF CONCERN FOR THE SLICK ROADS.
DISCUSSION:
A LARGE UPPER LEVEL LOW PRESSURE SYSTEM CURRENTLY IN NORTHERN MEXICO
WILL MOVE EAST THROUGH WEDNESDAY. MOIST AIR ON THE NORTHERN SIDE OF
THIS SYSTEM MAY REACH THE PANHANDLES EARLY TUESDAY MORNING. NEAR TO
SLIGHTLY BELOW FREEZING TEMPERATURES IN PLACE TUESDAY MORNING MAY
CREATE MIXED PRECIPITATION MAINLY ACROSS THE SOUTHWEST TEXAS
PANHANDLE. A COLD FRONT WILL MOVE INTO THE PANHANDLES FROM THE
NORTH TUESDAY NIGHT INTO WEDNESDAY MORNING. THIS FRONT WILL BRING
COLDER AIR TO THE PANHANDLES. THE LOW PRESSURE SYSTEM WILL CONTINUE
MOVING TO THE EAST LEAVING THE PANHANDLES ON THE NORTH SIDE OF THIS
FEATURE. WHEN THE COLD AIR FROM THE FRONT INTERACTS WITH THE MOIST
AIR FROM THE LOW PRESSURE SYSTEM…THE POTENTIAL FOR SNOWFALL WILL
DEVELOP MAINLY ACROSS THE SOUTHERN TEXAS PANHANDLE.
THERE IS STILL SOME UNCERTAINTY WITH THE TRACK OF THE LOW PRESSURE
SYSTEM. IF THE LOW MOVES FURTHER NORTH THAN CURRENTLY ANTICIPATED…
THEN THERE WILL BE THE POTENTIAL FOR HEAVIER SNOW AMOUNTS OF 3 TO 6
INCHES. HOWEVER…THE FORECAST MODELS CONTINUE TO SUGGEST THAT
THIS SYSTEM WILL REMAIN ON ITS CURRENT TRACK AND THUS ONLY PROVIDE 1
TO 3 INCHES OF SNOW FOR PANHANDLE LOCATIONS.

——————————————————
Next few days:
SNOWFALL MAY BE HEADED TO THE PANHANDLES TODAY THROUGH TUESDAY…
A LARGE LOW PRESSURE SYSTEM IS CURRENTLY LOCATED OVER SOUTHWESTERN
ARIZONA AND IS HEADING SOUTHEAST INTO NORTHERN MEXICO. PRECIPITATION
IS EXPECTED TO DEVELOP OUT AHEAD OF THIS LOW PRESSURE SYSTEM AND
BEGIN TO IMPACT THE TEXAS AND OKLAHOMA PANHANDLES THIS MORNING.
INITIALLY…LIGHT RAIN IS EXPECTED ACROSS THE WESTERN TEXAS AND
OKLAHOMA PANHANDLES. HOWEVER…COLDER AIR SITUATED IN THE WESTERN
OKLAHOMA AND NORTHWEST TEXAS PANHANDLE MAY ALLOW FOR A RAIN AND SNOW
MIX WHICH SHOULD THEN TRANSITION TO LIGHT SNOW LATER IN THE MORNING.
THIS COLDER AIR MAY REACH THE SOUTHWEST TEXAS PANHANDLE AND BRING THE
RAIN AND SNOW MIX DURING THE MID MORNING HOURS.
AT THIS TIME…THE BEST CHANCE FOR SNOW ACCUMULATIONS ARE EXPECTED TO
OCCUR ACROSS THE WESTERN TEXAS AND OKLAHOMA PANHANDLES. HOWEVER…
SNOW ACCUMULATIONS SHOULD GENERALLY REMAIN BELOW 1 INCH. A FEW
LOCATIONS IN THE WESTERN TEXAS AND OKLAHOMA PANHANDLES MAY EXPERIENCE
SNOW ACCUMULATIONS OF 1 TO 2 INCHES.
ON TUESDAY…THIS LOW PRESSURE SYSTEM SHOULD BE POSITIONED IN
NORTHERN MEXICO TRACKING TO THE NORTHEAST TOWARD THE TRANS PECOS
REGION. AS THIS SYSTEM MOVES TO THE NORTHEAST…THERE WILL BE
ANOTHER CHANCE FOR SNOWFALL MAINLY ACROSS THE SOUTHERN TEXAS
PANHANDLE. ONCE AGAIN…SNOW ACCUMULATIONS ARE EXPECTED TO BE
LIGHT. HOWEVER…IF THIS LOW PRESSURE SYSTEM MOVES FARTHER NORTH
THAN CURRENTLY ANTICIPATED…THEN HIGHER SNOWFALL TOTALS WILL BE
POSSIBLE.
PLEASE STAY TUNED TO NOAA WEATHER RADIO…OR THE NATIONAL WEATHER
SERVICE WEB SITE AT WWW.SRH.NOAA.GOV/AMA FOR ANY UPDATES RELATED TO
THIS SYSTEM.
