AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE ALBUQUERQUE NM
308 AM MDT THU SEP 15 2011

.DISCUSSION...
ALTHOUGH IT CONTINUES TO WEAKEN THE UPPER LOW CONTINUED TO
MAINTAIN A CLOSED CIRCULATION AS IT PROPAGATED SLOWLY
NORTHEASTWARD THROUGH NW AZ OVERNIGHT. MEANWHILE...THE BACK DOOR
COLD FRONT ONLY BARELY SEEPED INTO THE RIO GRANDE VALLEY. NAM AND
GFS SEEM TO INDICATE THAT THE FRONT WILL MIX OUT OF THE CENTRAL
VALLEY THIS AFTERNOON AND BECOME QUASI-STATIONARY ALONG THE EAST
SLOPES OF THE CENTRAL MOUNTAIN CHAIN. THE FAR EASTERN PLAINS WILL
CONTINUE TO BE FAVORED FOR PRECIPITATION THIS MORNING AS MOIST SW
FLOW ALOFT CONTINUES TO OVERRUN PERSISTENT LOW LEVEL UPSLOPE FLOW.
HOWEVER...THIS AFTERNOON THE LOW LEVEL CONVERGENCE ZONE IN CENTRAL
PARTS OF THE STATE SHOULD MAKE THE CENTRAL MOUNTAIN CHAIN THE
FOCUS THE MOST NUMEROUS SHOWERS AND STORMS. HPC PROGS CONTINUE TO
INDICATE THAT THE AREA FROM THE CENTRAL MOUNTAIN CHAIN EASTWARD
WILL BE FAVORED FOR THE GREATEST RAIN ACCUMULATION TODAY...WITH
MOST LOCATIONS RECEIVING BETWEEN A TENTH AND A HALF INCH. HIGH
TEMPERATURES WILL VARY FROM A FEW TO 12 DEGREES BELOW NORMAL
CENTRAL AND WEST...AND 12 TO 25 DEGREES BELOW NORMAL ACROSS THE
EAST.

TEMPERATURES WILL REBOUND FRIDAY THROUGH THE WEEKEND...ESPECIALLY
IN THE EAST AND TO A LESSER EXTENT IN THE WEST. THE UPPER LOW WILL
CONTINUE TO FILL AND CROSS CO AS A WEAK TROUGH FRIDAY AS ANOTHER
UPPER LEVEL TROUGH CROSSES THE GREAT BASIN MORE RAPIDLY IN ITS WAKE.
THE TWO FEATURES WILL KEEP A SOMEWHAT DIFFLUENT FLOW ALOFT OVER
NM...WHICH WILL WORK WITH MOISTURE ALREADY IN PLACE TO CONTINUE TO
PRODUCE A CHANCE OF SHOWERS AND THUNDERSTORMS FRIDAY AND SATURDAY.
THE BEST CHANCES WILL BE FOUND FRIDAY AFTERNOON ACROSS THE
NORTHWEST THIRD OF THE STATE. SLIGHT CHANCES WILL FAVOR THE
MOUNTAINS SATURDAY...BUT IT WILL BE HARD TO RULE OUT CONVECTION AT
LOWER ELEVATIONS. THE BASE OF THE SECOND UPPER TROUGH WILL
PROPAGATE EAST OF THE ROCKIES SATURDAY NIGHT WITH DRIER AND MORE
STABLE AIR IN ITS WAKE. THIS WILL ONLY YIELD SPOTTY CONVECTION
FAVORING THE MOUNTAINS AND THE EAST SLOPES OF THE CENTRAL MOUNTAIN
CHAIN.

GFS AND ECMWF ARE IN A LITTLE BETTER AGREEMENT ON A THIRD TROUGH
CROSSING MAINLY THE NORTHERN AND CENTRAL ROCKIES MONDAY AND MONDAY
NIGHT. THE WILL RESULT IN A BROADER FOOTPRINT OF ISOLATED SHOWERS
AND STORMS MOSTLY ALONG AND EAST OF THE CONTINENTAL DIVIDE. THE
SYSTEM SHOULD DRIVE A BACK DOOR COLD FRONT INTO EASTERN NM TUESDAY
AND TUESDAY NIGHT...SHIFTING THE FOCUS FOR CONVECTION TO LOCATIONS
ALONG AND EAST OF THE CENTRAL MOUNTAIN CHAIN AS THE BASE OF THE
TROUGH EXITS EASTWARD. AFTER HIGH TEMPERATURES MONDAY AND TUESDAY
SLIGHTLY ABOVE NORMAL IN THE EAST AND A FEW DEGREES BELOW NORMAL
CENTRAL AND WEST...THE FRONT WILL DROP EASTER READINGS A FEW DEGREES
BELOW NORMAL AGAIN ON WEDNESDAY.

.AVIATION...
ANOTHER ACTIVE 24 HOUR PERIOD ANTICIPATED ACROSS NORTHERN AND
CENTRAL NEW MEXICO. SURFACE COLD FRONT HAS PRESSED SOUTH THROUGH
MOST OF THE EASTERN PLAINS AND EASED INTO THE RIO GRANDE VALLEY.
SCATTERED TO NUMEROUS SHOWERS AND THUNDERSTORMS THROUGH THIS
EVENING. A FEW OF THE STORMS WILL BE STRONG WITH DOWNBURST WINDS AND
HAIL...BUT TORRENTIAL DOWNPOURS WITH LOCALIZED FLOODING WILL BE THE
MAIN THREAT. IFR TO LIFR CIGS AND VSBYS NEXT 24 HOURS DUE TO HEAVY
RAIN AND FOG WILL BE LIKELY ALONG WITH MOUNTAIN OBSCURATIONS. ALL
TAF SITES WILL BE IMPACTED WITH KLVS...KTCC AND KROW THE MOST
AFFECTED.

NEXT AVIATION DISCUSSION SCHEDULED FOR 21Z. CHJ

&&

.FIRE WEATHER...
RAIN AND A FEW EMBEDDED THUNDERSTORMS CONTINUE OVER THE EAST EARLY
THIS MORNING. SCATTERED TO NUMEROUS SHOWERS AND STORMS WILL IMPACT
ALL OF THE FORECAST AREA INTO TONIGHT WITH SIGNIFICANT WETTING RAINS
AT MANY LOCATIONS. ONLY WEAK EAST WINDS HAVE BEEN REPORTED INTO THE
RIO GRANDE VALLEY SO FAR THIS MORNING. MINIMUM RH VALUES TODAY WILL
BE HIGH...RANGING FROM THE 40S AND 50S IN THE WEST TO THE 60S TO
AROUND 80 IN THE EAST. RH RECOVERIES TONIGHT WILL BE EXCELLENT AREA
WIDE. VENTILATION RATES WILL BE POOR IN THE EAST TODAY.

FRIDAY WILL BE LESS ACTIVE AS DRIER AIR BEGINS TO WORK INTO THE
WEST. MINIMUM RH VALUES WILL PLUMMET TO THE 30S AND 40S EVERYWHERE
WITH STILL GOOD TO EXCELLENT RH RECOVERIES FRIDAY NIGHT. VENTILATION
RATES WILL BE MUCH IMPROVED OVER THE EAST FRIDAY.

AN OVERALL DRYING TREND WILL CONTINUE THIS WEEKEND WITH A RETURN TO
WARMER TEMPERATURES. A WEAK BACKDOOR COLD FRONT COULD EDGE INTO THE
FAR NORTHEAST PLAINS ON SUNDAY WITH ANOTHER ONE ON TUESDAY. BUT RAIN
CHANCES LOOK MINIMAL OVERALL THROUGH AT LEAST THE END OF NEXT WEEK.
