Drought in New Mexico, May 1 to 31, 2011

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE ALBUQUERQUE NM
306 PM MDT SAT APR 30 2011

.DISCUSSION...

...A VERY COMPLEX WEATHER SCENARIO OVER THE NEXT 48 HOURS...

THE LATEST SATELLITE AND SURFACE OBSERVATION TRENDS COMPARED WITH
THE 12Z/18Z MODEL SUITE CONFIRMS THE DEVELOPING WINTER STORM SYSTEM
TONIGHT AND SUNDAY WILL DELIVER A WINTER PUNCH TO THE REGION THRU
MONDAY. AN UPPER LEVEL VORT AXIS CURRENTLY STRETCHING FROM THE
NORTHERN GREAT PLAINS SW ACROSS THE CENTRAL ROCKIES INTO THE GREAT
BASIN WILL SAG SOUTH THIS EVENING. MEANWHILE...AN 80-100 KNOT UPPER
LEVEL JET CORE AS EVIDENCED BY THE LATEST ACARS DATA IS DEVELOPING
SOUTHWARD OUT OF THE PACIFIC NW. THIS FEATURE WILL COUPLE WITH THE
SW TAIL OF THE CURRENT UPPER VORT AXIS AND DEEPEN BOTH THE 500 AND
700MB LOWS OVER WESTERN NM. A 30-40 KT EASTERLY 700MB JET WILL
DEVELOP IN RESPONSE ALONG THE CENTRAL HIGH PLAINS. SURFACE HIGH
PRESSURE WILL ALSO STRENGTHEN OVER SE COLORADO...SETTING THE STAGE
FOR A SERIOUS GAP WIND EVENT IN THE RIO GRANDE VALLEY TONIGHT.
INCREASING CONFIDENCE BASED ON THE 18Z NAM/12Z EURO/AND 2 LOCAL
STUDIES...WILL UPGRADE THE CURRENT HIGH WIND WATCH TO A WARNING
FOR THE AREA FROM KSAF SOUTH TO KABQ AND BERNARDO.

STRONG COLD ADVECTION AT 700MB FROM THE FRONT RANGE AND DEEP UPSLOPE
FLOW WILL FAVOR RAPID TOP-DOWN MOISTENING AFTER MIDNIGHT OVER THE
NORTHERN MTS. WILL UPGRADE THE CURRENT WINTER STORM WATCH TO A
WARNING AND ADD THE JEMEZ MTS WHERE LOW LEVEL SE FLOW WILL ENHANCE
SNOWFALL OVER THE HIGH TERRAIN THROUGH MONDAY MORNING. SNOW AMOUNTS
PER HPC QPF/SNOW GRAPHICS AND LOCAL MODEL SUGGEST AMOUNTS BETWEEN
6 TO 12 INCHES IN THE WARNING AREA. WILL HOLD OFF AN ISSUANCE OF
ADVISORIES FOR THE SURROUNDING HIGHLANDS SINCE THE BULK OF THE BEST
DYNAMICS AND QPF MAY OCCUR SUNDAY AFTERNOON...LIMITING SNOWFALL
ACCUMS IN THOSE AREAS. THE OTHER AREA FOR CONCERN IS ALONG THE
CONTINENTAL DIVIDE WHERE STRONG SURFACE CONVERGENCE WILL SIT BELOW
UPPER DIVERGENCE CREATING A BAND OF MODERATE TO POTENTIALLY HEAVY
SNOWFALL FOR A FEW HOURS SUNDAY NIGHT. AGAIN WILL LET FOLLOWING
SHIFTS EXAMINE THIS FURTHER.

PRECIP WILL LINGER OVER THE STATE INTO MONDAY AS THE STORM SYSTEM
BEGINS TO FILL AND MOVE EAST. TEMPS SUNDAY AND MONDAY WILL BE WELL
BELOW NORMAL WITH RECORD LOW MAX TEMPS AND RECORD LOW MIN TEMPS
LIKELY FOR SEVERAL LOCALES. THE BEST POTENTIAL FOR WIDESPREAD SUB
FREEZING TEMPS...INCLUDING THE ABQ METRO AREA...WILL BE TUESDAY
MORNING AS A 1029MB SETS UP OVER THE RIO GRANDE VALLEY.

CONDITIONS MODERATE VERY QUICKLY BY TUESDAY AFTERNOON AND ESPECIALLY
WEDNESDAY WHEN TEMPS WILL END UP ABOVE NORMAL AGAIN. EXPECT WARM TEMPS
AND LIGHT TO BREEZY WINDS THROUGH THE REMAINDER OF THE WEEK.

GUYER

&&

.AVIATION...
VFR CONDITIONS WILL PREVAIL AT AIRPORTS IN THE NORTHERN TWO THIRDS
OF NEW MEXICO THROUGH SATURDAY EVENING. A BACK DOOR COLD FRONT WILL
THEN PLUNGE SOUTH THROUGH THE NORTHEAST CORNER OF THE STATE...MOVING
FURTHER SOUTH AND WEST OVERNIGHT. GUSTY NORTH TO NORTHEAST WINDS
BEHIND THE COLD FRONT WILL BRING AREAS OF LOW CLOUDS ALONG WITH MUCH
COLDER AIR. BY DAYBREAK SUNDAY STRONG EAST CANYON WINDS WILL HAVE
SURGED INTO THE MID RIO GRANDE VALLEY...GUSTING ABOVE 40 KTS MOST
AREAS. RAIN AND SNOW SHOWERS ARE LIKELY SUNDAY MORNING IN THE
NORTHERN MOUNTAINS WITH PATCHY IFR CONDITIONS...ESPECIALLY OVER THE
MOUNTAINS. MVFR TO IFR CONDITIONS ARE LIKELY SUNDAY MORNING ALONG
INTERSTATE 40 BETWEEN LAS VEGAS AND RATON IN LOW CLOUDS AND PRECIP.

NEXT AVIATION DISCUSSION SCHEDULED FOR 09Z.

&&

.FIRE WEATHER...
MAY IS SET TO BURST INTO NORTHERN NEW MEXICO LOOKING MORE WINTER
LIKE THAN ANYTHING WE HAVE SEEN IN MONTHS. A STRONG BACK DOOR COLD
FRONT OVER SOUTHEAST COLORADO SATURDAY EVENING WILL SURGE SOUTH
THROUGH THE NEW MEXICO PLAINS OVERNIGHT AND WEST TO THE RIO GRANDE
VALLEY. MEANWHILE A COLD CORE LOW ALOFT SINKS SOUTH TO THE FOUR
CORNERS REGION. THE FRONT AND LOW WILL COMBINE TO GENERATE MUCH
COLDER AND WETTER CONDITIONS FOR MUCH OF NORTHERN NEW MEXICO
STARTING LATE TONIGHT AND PERSISTING THROUGH SUNDAY NIGHT. THIS
COULD BE ONE OF THE BETTER WINTER STORMS OF 2011 FOR THE JEMEZ
MOUNTAINS...EVEN IF IT IS THE FIRST DAY OF MAY.

GUSTY NORTH TO NORTHEAST WINDS BEHIND THE COLD FRONT WILL USHER IN A
MUCH COLDER AND MORE MOIST AIRMASS. STRONG EAST CANYON WINDS ARE
EXPECTED TO INVADE THE MID RIO GRANDE VALLEY LATE TONIGHT AND
PERSIST THROUGH ABOUT NOON SUNDAY.

DAYTIME TEMPERATURES SUNDAY WILL BE 20 TO 30 DEGREES COLDER THAN
THEY WERE SATURDAY IN THE NORTHERN MOUNTAINS AND THE EASTERN HALF OF
NEW MEXICO BEHIND THE COLD FRONT. THE COLDER AIR WILL GRADUALLY WORK
ITS WAY FURTHER WEST TO THE CONTINENTAL DIVIDE DURING THE DAY SUNDAY.
THIS OBVIOUSLY WILL RESULT IN HIGHER HUMIDITIES AND TEMPORARILY
SQUASH ANY THREAT FOR CRITICAL FIRE WEATHER CONDITIONS INTO MONDAY.
VENTILATION RATES WILL TAKE A HIT ON MONDAY ALSO.

A RETURN TO DRIER CONDITIONS WILL TAKE PLACE TUESDAY AS ZONAL FLOW
ALOFT RETURNS...WHILE DAYTIME TEMPERATURES WARM TO WITHIN A FEW
DEGREES OF NORMAL BY TUESDAY AFTERNOON. SURFACE AND 20 FOOT WINDS
TUESDAY EAST OF THE CENTRAL MOUNTAIN CHAIN WILL ALSO RETURN TO A
BRISK SOUTHERLY REGIME.

WEDNESDAY AND THURSDAY LOOK TO BE DRY AND SEASONABLY WARM ACROSS OUR
AREA.
