.AVIATION...
18Z TAF CYCLE
TRUSTED MESOSCALE MODELS DEPICT SLOW MOVING -SHRA/-TS FAVORING
THE CENTRAL MT CHAIN AND ADJACENT E SLOPES...AS WELL AS NEW
MEXICOS SOUTHERN HIGH TERRAIN TODAY. MOST OF THE ACTIVITY WILL
DRIFT TO THE SE AROUND 5 TO 15 MPH...WHICH SHOULD EVENTUALLY TRACK
CELLS NEAR KTCC AND KROW. MODELS ALSO SUGGEST A FEW CELLS WILL POP
UP NEAR KSAF...KABQ...KAEG AND KGUP...THOUGH TS PROBABILITIES
WERE LOW ENOUGH TO USE VCSH RATHER THAN VCTS IN THESE TAFS. A FEW
ISOLD CELLS COULD LINGER INTO THE LATE NIGHT HOURS MAINLY ALONG
AND S OF HWY 60. A MIXTURE OF WET AND DRY MICROBURSTS ARE EXPECTED
TODAY WITH LOCALIZED AND ERRATIC WIND GUSTS NEAR 45 KT.

.PREV DISCUSSION...346 AM MDT WED SEP 9 2015...
.SYNOPSIS...
BACK DOOR COLD FRONT HAS MADE IT TO A LITTLE WEST OF THE RIO
GRANDE AND HAS DRAGGED A MODEST AMOUNT OF ADDITIONAL LOW LEVEL
MOISTENING WITH IT WEST OF CENTRAL MOUNTAIN CHAIN...BUT A LITTLE
MORE SO TO ITS EAST. THUS SHOWERS AND THUNDERSTORMS WILL FAVOR
AREAS ALONG AND A LITTLE WAYS EAST OF THE CENTRAL MOUNTAIN
CHAIN...GENERALLY ISOLATED TO SCATTERED COVERAGE WITH THE BEST
COVERAGE SOUTH OF INTERSTATE 40. ALSO AREAS WEST OF CENTRAL
MOUNTAIN CHAIN AND SOUTH OF INTERSTATE 40 WILL SEE FAIR IF NOT
LIKELY POTENTIAL CENTERING ON...AS USUAL...THE GILA REGION.
ANOTHER BACK DOOR COLD FRONT LOOKS TO ARRIVE THURSDAY NIGHT INTO
FRIDAY. THIS WILL BRING COOLER CONDITIONS TO EASTERN NEW MEXICO
AS WELL AS AN INCREASED CHANCE FOR PRECIPITATION ONCE AGAIN.
THROUGH AT LEAST THIS NEXT WEEKEND HOWEVER THE NORTHWEST QUARTER
TO THIRD OF THE STATE AS WELL AS PORTIONS OF THE RIO GRANDE VALLEY
WILL SEE THE LOWEST CHANCES FOR SIGNIFICANT RAINFALL.

&&

.DISCUSSION...
RATHER MODEST BACK DOOR COLD FRONT LOCATED A LITTLE WEST OF THE
RIO GRANDE EARLY THIS MORN AND WILL NOT LIKELY MOVE TOO MUCH
FARTHER WEST TODAY AS IT SLOWLY WEAKENS. IT HAS IMPORTED A
MARGINALLY HIGHER AMOUNT OF ADDITIONAL LOW LEVEL MOISTURE INTO RIO
GRANDE VALLEY...BUT MUCH OF WHAT DID MAKE IT WEST OF CENTRAL MTN
CHAIN WILL MIX OUT TODAY WITH THE INCREASINGLY DRIER AIR FILTERING
IN FROM THE NW. WITH BETTER AND DEEPER MOISTURE NEAR AND ESPEC
EAST OF CENTRAL MTN CHAIN SHOWERS AND THUNDERSTORMS WILL FAVOR
THIS AREA...EVEN MORE SO TO SOUTH OF INTERSTATE 40. ALSO AREAS
WEST OF CENTRAL MOUNTAIN CHAIN AND SOUTH OF INTERSTATE 40 WILL SEE
FAIR IF NOT LIKELY POTENTIAL CENTERING ON THE GILA REGION.
ANOTHER BACK DOOR COLD FRONT...PROBABLY STRONGER THAN THE CURRENT
ONE...LOOKS TO ARRIVE LATER THU NIGHT INTO FRI. THIS WILL SWEEP
FAIRLY QUICKLY TO THE SOUTH AND WEST ACROSS THE STATE BRINGING
COOLING AND SOME DEGREE OF LOW LVL MOISTURE RECHARGE...AGAIN MORE
SO FOR EASTERN AND SOUTHERN AREAS...AS AN INCREASED CHANCE FOR
PRECIPITATION ONCE MORE. THROUGH AT LEAST THIS NEXT WEEKEND
HOWEVER THE NORTHWEST QUARTER TO THIRD OF THE STATE AS WELL AS
PORTIONS OF THE RIO GRANDE VALLEY WILL SEE THE LOWEST CHANCES FOR
SIGNIFICANT RAINFALL.

.FIRE WEATHER...
NW FLOW ALOFT RESULTING IN A RELATIVELY WEAK BACKDOOR BOUNDARY
PUSHING WESTWARD INTO THE MIDDLE RIO GRANDE VALLEY EARLY THIS
MORNING. THIS FEATURE IS EXPECTED TO RESULT IN A SLIGHT UPTICK IN
THUNDERSTORM ACTIVITY TODAY...ESPECIALLY FROM THE SOUTHERN SANGRE DE
CRISTOS SOUTH TO THE CENTRAL HIGHLANDS FROM CLINES CORNERS TO
CORONA. MODELS AT ODDS AS TO THE DEPTH OF LOW LEVEL MOISTURE
THURSDAY. GFS SUGGESTING THE DRY AIR ALOFT WILL WIN OUT WHEREAS THE
NAM IS DEEPER WITH THE LOW LEVEL MOISTURE FROM THE EAST SLOPES OF
THE CENTRAL MOUNTAIN CHAIN EWD. LEANING TOWARD THE NAM SOLUTION
GIVEN THE GENERAL TENDENCY FOR THE MODELS TO UNDER FORECAST
CONVECTION IN NORTHWEST FLOW ALOFT WITH EAST OR SELY LOW LEVEL FLOW.

MUCH STRONGER BACKDOOR FRONT/BOUNDARY PLOWS THROUGH THE ERN PLAINS
FRIDAY MORNING AND INTO THE RIO GRANDE VALLEY AND POINTS WEST FRIDAY
AFTERNOON AND EVENING. GFS AND NAM IN GOOD AGREEMENT THAT CONVECTION
FRIDAY AFTERNOON AND EVENING WILL FAVOR THE AREAS ALONG AND NEAR THE
FRONT. ON SATURDAY...NORTHWEST WINDS SEND THE LOW LEVEL MOISTURE
BEHIND THE FRONT SEWD WITH SHOWERS AND THUNDERSTORMS FAVORING THE
SOUTHWEST MTNS AND AREAS ALONG AND EAST OF THE CENTRAL MOUNTAIN
CHAIN.

UPPER HIGH CENTER SLIDES SLIGHTLY EAST SUNDAY...CENTERED OVER SW
NM/SE AZ. SUNDAY NOW LOOKING LIKE A DOWN DAY FOR MOST AREAS WITH DRY
NW FLOW AT ALL LEVELS. GFS AND ECMWF IN GOOD AGREEMENT THAT A WEAK
UPPER LEVEL LOW/TROUGH WILL MOVE SLOWLY EWD TO NEAR SAN DIEGO ON
MONDAY. A RELATIVELY MOIST SOUTHWEST FLOW ALOFT AHEAD OF THE LOW
WILL BRING BACK CHANCES FOR SHOWERS AND THUNDERSTORMS TO WESTERN NEW
MEXICO MONDAY AND TO WESTERN AND NORTHERN NEW MEXICO TUESDAY. THE
LOW TRANSLATES EWD THROUGH AZ TOWARD MID WEEK...POSSIBLY TAPPING
SUBTROPICAL MOISTURE FROM NORTHERN MEXICO.

MAXIMUM VENT RATES BEHIND EACH BACKDOOR FRONT/BOUNDARY WILL LIKELY
REMAIN POOR TO FAIR OVER A LARGE PORTION OF THE AREA TODAY AND AGAIN
FRIDAY AND SATURDAY BEFORE IMPROVING TO GOOD TO EXCELLENT SUNDAY
INTO EARLY NEXT WEEK.
