Hail and Damaging Wind in New Mexico, June 20, 2008

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE ALBUQUERQUE NM
303 PM MDT FRI JUN 20 2008

.DISCUSSION...MAIN CONCERN AGAIN TODAY IS ONGOING CONVECTION AND
WHERE CONVECTION WILL FIRE TOMORROW.

STORMS HAVE ALREADY DEVELOPED ALONG THE EASTERN SLOPES OF THE SANGRE
DE CRISTOS. LOW LEVEL MOISTURE IS NOT AS JUICY AS YESTERDAY...AND
THUS STORMS HAVE NOT REACHED THE INTENSITY THAT THEY DID YESTERDAY
BY THIS TIME. NONETHELESS...CAPE VALUES ON THE ORDER OF 1000-1500 J/KG
ARE NOTED ON THE LAPS ANALYSIS...WHICH IS MORE THAN SUFFICIENT FOR A
FEW SEVERE STORMS. HOWEVER...SHEAR IS LACKING...AS EVIDENCE BY THE
TUCUMCARI PROFILER SHOWING VERY LITTLE WIND. THOUGH MODEL GUIDANCE
SHOWS SOME INDICATION THAT SHEAR WILL INCREASE LATER THIS EVENING.
LIKE PREVIOUS EVENINGS...STORMS ARE EXPECTED TO MERGE AND FORM INTO
ONE OR MORE CLUSTERS AND SURGE SOUTH-SOUTHEAST THIS EVENING AND
OVERNIGHT. THIS WILL AGAIN SEND AN OUTFLOW BOUNDARY THROUGH THE GAPS
OF THE CENTRAL MOUNTAIN CHAIN. AT THIS TIME...DOES NOT APPEAR ABQ
EAST WIND WILL BE AS STRONG.  IT WILL ALSO BE FIGHTING OUTFLOW
BOUNDARIES FROM THE NORTH AND WEST FROM ONGOING CONVECTION ALONG THE
NORTHERN MOUNTAINS AND THE CONTINENTAL DIVIDE. FOR THE REMAINDER OF
THE EVENING...STORMS WEST OF THE CENTRAL MOUNTAIN CHAIN ARE EXPECTED TO
REMAIN SUB-SEVERE...AND WILL PROVE TO BE MORE OF A GUSTY WIND THREAT
AS THE STORMS ARE A MIX OF THE WET AND DRY VARIETY.

FOR SATURDAY...ALL INDICATIONS SUGGEST THAT A MCS...THAT IS EXPECTED
TO FORM OVER THE HIGH PLAINS OF COLORADO TONIGHT...WILL DIVE
SOUTH-SOUTHEAST OVER FAR EASTERN NM AND THE PANHANDLES SATURDAY
MORNING. THOUGH EXACT PLACEMENT OF THIS MCS IS STILL IN
QUESTION...AS UPPER HIGH AS MOVED WESTWARD A BIT...THIS WILL SEND
ANOTHER STRONG OUTFLOW BOUNDARY WESTWARD...BUT THIS TIME DURING THE
DAYTIME HOURS. THIS OUTFLOW BOUNDARY IS EXPECTED TO SURGE JUICIER
LOW LEVEL MOISTURE ACROSS THE EASTERN PLAINS.  THUS...CONVECTION
WILL LIKELY FIRE ALONG THE EAST SLOPES OF THE CENTRAL MOUNTAIN CHAIN
DURING THE AFTERNOON. ONCE AGAIN...STORMS MAY BE SEVERE ACROSS THE
EASTERN PLAINS...AND CAPABLE OF LARGE HAIL AND DAMAGING WINDS.  WEST
OF THE CENTRAL MOUNTAIN CHAIN...A MIX OF WET AND DRY STORMS ARE
POSSIBLE AGAIN.

ISOLATED TO SCATTERED STORMS WILL DEVELOP AGAIN ON SUNDAY...FAVORING
THE HIGHER TERRAIN BEFORE MOVING OFF TO THE SOUTHEAST.

AS MOISTURE REMAINS ACROSS THE EASTERN PLAINS...ISOLATED TO
SCATTERED THUNDERSTORMS ARE POSSIBLE THROUGH MID WEEK.

34

&&

.AVIATION...
ISOLATED AND SCATTERED THUNDERSTORMS WILL BE POSSIBLE AT OR NEAR ALL
SITES EAST OF THE CONTINENTAL DIVIDE THROUGH THIS EVENING WITH SOME
STORMS LASTING INTO THE OVERNIGHT HOURS. CB IN TAF GROUPS WITHOUT
VCTS USED TO INDICATED SMALLER PROBABILITY OF TS DEVELOPMENT AT OR NEAR
INDIVIDUAL TAF SITES. CIGS COULD DROP TO MVFR WITH BRIEF INCURSIONS
INTO IFR AT SITES EAST OF THE CENTRAL MOUNTAIN CHAIN DUE TO LOW
CLOUDS OVERNIGHT. THE HIGHEST CONFIDENCE OF DECREASED CIGS WOULD BE
AT SITES NORTH OF I40 AND EAST OF THE CENTRAL MOUNTAINS. CIGS SHOULD
RAISE TO VFR CONDITIONS BY EARLY TO MID MORNING. GAP WINDS WILL
AGAIN OCCUR ACROSS THE CENTRAL MOUNTAIN CHAIN AT OR AROUND 05Z
TONIGHT BRINGING WINDY CONDITIONS WITH GUSTS UP TO 35 KNOTS BELOW
CANYONS.

NEXT AVIATION DISCUSSION SCHEDULED FOR 09Z.

53/44

.FIRE WEATHER...
TONIGHT ANOTHER BOUNDARY WILL PUSH SOUTH AND WEST INTO THE FORECAST
AREA WITH ANOTHER STRONG EAST WIND BELOW CANYONS OPENING INTO THE
RIO GRANDE VALLEY. THIS BOUNDARY WILL CAUSE WINDS ACROSS THE EASTERN
PLAINS TO GUST AND SHIFT OUT OF THE NORTHEAST AND EAST FOR MUCH OF
THE NIGHT. AS A RESULT OF THE INCREASED MOISTURE...A DAILY MIX OF
ISOLATED TO SCATTERED THUNDERSTORMS IS EXPECTED EACH AFTERNOON AND EVENING
THROUGH THE WEEKEND. SOME THUNDERSTORMS WILL PRODUCE LITTLE OR NO
RAIN ALONG AND WEST OF CONTINENTAL DIVIDE WHERE THE HAINES INDEX
VALUES REACH LEVEL 6. GREATER THUNDERSTORM COVERAGE WILL OCCUR ACROSS
EASTERN SECTIONS OF THE STATE WHERE MOISTURE WILL BE DEEPER.

EARLY NEXT WEEK...THUNDERSTORM CHANCES WILL DECREASE ACROSS THE WEST
AS THE UPPER LEVEL HIGH PRESSURE CENTER SHIFTS TOWARD THE EAST.
