Flash Flood Warning 17, NWS Albuquerque, NM

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE ALBUQUERQUE NM
252 AM MDT TUE JUL 20 2010

.DISCUSSION...
LITTLE CHANGE TO GOING FORECAST. SHOWERS AND THUNDERSTORMS TO
INCREASE IN COVERAGE MID TO LATE WEEK.

A FEW SHOWERS AND THUNDERSTORMS CONTINUE ACROSS THE CWA AGAIN THIS
MORNING. THEY MAY NOT COMPLETELY DIMINISH BEFORE THE LATE
MORNING/EARLY AFTERNOON CONVECTION BEGINS. CONVECTIVE COVERAGE WILL
BE SIMILAR TO OR A BIT MORE WIDESPREAD THIS AFTERNOON. WITH THE
CENTER OF THE UPPER HIGH SHIFTING EAST...STEERING FLOW SHOULD BE
MORE TOWARD THE NORTH OR NORTHEAST...BUT WILL REMAIN SLOW. DRIEST
AREA WILL ONCE AGAIN BE THE SOUTHEAST PLAINS.  BY LATE THIS
AFTERNOON OR EARLY THIS EVENING...BACK DOOR FRONT WILL SKIRT INTO
THE NORTHEAST PLAINS.  THIS WILL BE A FOCUS FOR THUNDERSTORM
DEVELOPMENT THIS EVENING. A FEW STRONG STORMS WILL BE POSSIBLE ALONG
THE BORDER WHERE THE NAM IS BOASTING UP TO 2000 J/KG OF CAPE.

BY WEDNESDAY AND THURSDAY...STORMS WILL BECOME MORE WIDESPREAD AS
THE DEEPER PLUME OF MOISTURE INCHES INTO WESTERN NEW MEXICO AS THE
UPPER HIGH CENTER CONTINUES TO SHIFT EAST. PRECIPITATION CHANCES
INCREASE ACROSS THE WESTERN TWO-THIRDS OF THE STATE. STEERING FLOW
WILL CONTINUE TO BE WEAK...THUS THE POTENTIAL FOR FLOODING PROBLEMS
WILL INCREASE AS WELL. HOWEVER...TEMPERATURES WILL MODERATE TO NEAR
SEASONAL NORMALS THANKS TO THE INCREASED CLOUD COVER AND PRECIP.

UPPER LEVEL PATTERN REMAINS MURKY INTO THE WEEKEND. STILL APPEARS
THAT THE HIGH WILL TRY TO RE-ESTABLISH ITSELF OVER OR NEAR THE
STATE...BUT WHERE THE CENTER WILL RESIDE REMAINS A MYSTERY.
REGARDLESS...RESIDUAL MOISTURE WILL BE SUFFICIENT FOR DAILY ROUNDS
OF THUNDERSTORM ACTIVITY.

34

&&

.AVIATION...
HIGH PRESSURE REMAINS OVER NEW MEXICO. DESPITE THE HIGH...ISOLATED
TO SCATTERED THUNDERSTORMS WILL AGAIN AFFECT NORTHERN AND CENTRAL
NEW MEXICO THIS AFTERNOON INTO TONIGHT. TERMINALS MOST LIKELY TO BE
AFFECTED BY THE THUNDERSTORMS ARE GUP...SAF...LVS AND IN THE EVENING
ABQ...ALTHOUGH FOR NOW ONLY GOING WITH VCTS AT THESE SITES. DESPITE
THE STORMS CONDITIONS WILL REMAIN MOSTLY VFR...WITH THE BEST CHANCE
FOR MVFR CONDITIONS FOUND ACROSS THE SOUTHWEST AND WEST CENTRAL
MOUNTAINS. OTHERWISE...LOOK FOR MTN TOP OBSCD. SHOWERS AND STORMS
WILL GRADUALLY DIMINISH AFTER MIDNIGHT TONIGHT...BUT A FEW SHOWERS
WILL LINGER UNTIL DAYBREAK. MORE WIDESPREAD ACTIVITY EXPECTED
WEDNESDAY.

NEXT AVIATION DISCUSSION SCHEDULED FOR 21Z. CHJ

&&

.FIRE WEATHER...
HOT CONDITIONS AND ISOLATED TO SCATTERED THUNDERSTORMS FAVORING THE
WESTERN HALF WILL CONTINUE TODAY. CONFIDENCE REMAINS VERY HIGH THAT
THE UPPER HIGH WILL MIGRATE TO THE EAST OF THE STATE AND ALLOW A
MORE CLASSIC MONSOON MOISTURE PUSH LATER TUESDAY AND LASTING THROUGH
AT LEAST THE REST OF THE WEEK. WETTING SHOWER AND THUNDERSTORM
COVERAGE WILL INCREASE...ESPECIALLY WEDNESDAY AND THURSDAY ACROSS
THE WESTERN HALF OF THE STATE. THERE IS ALSO A BETTER SHOT AT LONGER
DURATION OVERNIGHT RAINFALL AS WELL UNDER THIS TYPE OF PATTERN. THE
MAIN QUESTION MARK CONSISTS WITH HOW LONG THIS CLASSIC MONSOONAL
PATTERN WILL LAST OVER THE AREA.

IN THE NEAR TERM...SOME INCREASE IN WETTING THUNDERSTORMS TODAY AND
TONIGHT. STORMS WILL START OVER THE MOUNTAINS THIS AFTERNOON AND
MOVE SLOWLY OFF THE HIGHER TERRAIN IN ERRATIC DIRECTIONS AS HIGH
PRESSURE SHIFTS EASTWARD. THE WESTERN HALF OF THE FORECAST AREA
WILL BE FAVORED. TEMPERATURES WILL REMAIN HOT TODAY...ALTHOUGH
PERHAPS NOT AS EXTREME IN PLACES LIKE FARMINGTON AND ALBUQUERQUE.
LOOK FOR GOOD TO EXCELLENT HUMIDITY RECOVERIES TONIGHT WITH WARM
OVERNIGHT LOWS.

LOWER TEMPERATURES AND HIGHER HUMIDITIES WILL OCCUR WEDNESDAY AND
THURSDAY AS THE UPPER HIGH MIGRATES TO THE EAST OF NEW MEXICO.
CLOCKWISE CIRCULATION AROUND THE UPPER HIGH WOULD PULL ADDITIONAL
MOISTURE UP FROM THE SOUTH. ONCE AGAIN...CLOUD COVER...MODERATING
TEMPERATURES AND A LARGER WETTING RAIN COVERAGE WILL AFFECT THE
WESTERN HALF OF THE FORECAST AREA. AS A RESULT...MINIMUM RH VALUES
WOULD FINALLY CLIMB ABOVE 20 PERCENT WITH GOOD TO EXCELLENT
RECOVERIES OVERNIGHT. AS MENTIONED ABOVE...THERE IS A MUCH BETTER
SHOT AT A LONGER DURATION WETTING RAIN EVENT DURING THE OVERNIGHT
PERIOD SUCH AS WED AND THUR NIGHTS AS WELL.

DUE TO A PACIFIC WAVE PASSAGE TO THE NORTH...IT WILL BE POSSIBLE
THAT THE MAIN MONSOONAL CIRCULATION COULD GET SQUASHED OR INTERRUPTED
THIS WEEKEND. ALTHOUGH ENOUGH MOISTURE WOULD BE IN PLACE TO PROVIDE
DECENT CHANCES OF WETTING RAIN FOR MOST OF THE AREA DURING THE
WEEKEND PERIOD AS MOISTURE RECYCLES. IT DOESNT APPEAR THAT THE
MODELS ARE DEPICTING A SIGNIFICANT DRY AIR INTRUSION INTO NEW MEXICO
BEHIND THE WAVE PASSAGE SO THAT IS GOOD. AS IS TYPICAL WITH THESE
TYPES OF INTERRUPTIONS...THE WEATHER MODELS ARE DEPICTING A
DEFORMATION ZONE SETTING UP OVER THE STATE DURING THIS PERIOD. AS
TIME GOES ON...THE BETTER COVERAGE OF STORMS WOULD BE FOUND ALONG
AND TO THE SOUTH OF THIS DEFORMATION ZONE. EVENTUALLY DRIER AIR
WOULD TRY TO FIND ITS WAY INTO NORTHWEST NEW MEXICO FROM THE GREAT
BASIN LATER IN THE PERIOD BUT THAT APPEARS TO BE A LONG WAYS OFF.
ESPECIALLY IF THE UPPER HIGH WOULD ONCE AGAIN MIGRATE BACK OVER THE
STATE.

THE AREA WHICH STANDS TO SEE THE LEAST CHANCE OF WETTING
PRECIPITATION THROUGH THE NEXT SEVERAL DAYS WOULD BE ACROSS THE
SOUTHEAST. WIND DURING THIS PERIOD WOULD BE DOMINATED BY OUTFLOW
WINDS AND SOME OCCASIONAL BREEZINESS ACROSS THE EASTERN PLAINS.
ALSO LOOKING FOR PERIODS OF ENHANCED GAP WINDS ALONG THE CENTRAL
MOUNTAINS.
