AREA FORECAST DISCUSSION...UPDATED
NATIONAL WEATHER SERVICE ALBUQUERQUE NM
1159 AM MDT WED JUN 17 2015

.AVIATION...
18Z TAF CYCLE
LESS COVERAGE OF SH/TS IS EXPECTED TODAY. THE GREATEST TS THREAT
OR IMPACT FOR TERMINAL SITES IS AT LVS AND TCC. CANT RULE OUT
IMPACTS AT ROW OR SAF AS WELL BUT WILL GO WITH VCSH AT THIS TIME.
THE DRIER VARIETY OF SH/TS WILL BE FOUND OVER CENTRAL AREAS SO
CANT RULE OUT GUSTY OUTFLOW WINDS. HAVE THAT BUILT INTO THE
AEG/ABQ/SAF FORECAST. COULD BE A LITTLE TOO BULLISH AT AEG/ABQ BUT
OUTFLOWS COULD TRAVEL A FAIR DISTANCE TODAY. PERHAPS SOME BRIEF
MTN TOP OBSCD ALONG THE CENTRAL MTNS BUT SHOULDNT LAST TOO LONG IF
IT EVEN OCCURS AT ALL. LOW CIG DVLP LIKE LAST NIGHT IS LESS LIKELY
FOR TONIGHT ACROSS THE FAR EAST BUT THERE IS A LITTLE BIT OF
INDICATION FROM ONE OF THE MODELS. WILL MONITOR ACCORDINGLY. MOST
OF THE SH/TS SHOULD HAVE DIMINISHED BY MIDNIGHT BUT CANT RULE OUT
CONTINUED CELLS ACROSS SC/SE AREAS AFTER MIDNIGHT.

.PREV DISCUSSION...336 AM MDT WED JUN 17 2015...
.SYNOPSIS...
HIGH PRESSURE OVER THE EASTERN PACIFIC WILL BEGIN TO EXTEND OVER
NEW MEXICO...PUSHING DRIER AIR INTO WESTERN PARTS OF THE STATE.
SUFFICIENT MOISTURE WILL LINGER OVER THE EASTERN HALF OF THE STATE
TODAY AND INTO THURSDAY...KEEPING ISOLATED TO SCATTERED SHOWERS
AND THUNDERSTORM IN THE FORECAST. HOWEVER...THE TREND OF DRIER
AIR PUSHING EASTWARD WILL GRADUALLY LOWER RAINFALL PROBABILITIES
BY THE WEEKEND WHILE TEMPERATURES BEGIN TO CLIMB SLIGHTLY ABOVE
AVERAGE. HIGH PRESSURE WILL ESTABLISH ITSELF DIRECTLY OVER THE
LAND OF ENCHANTMENT BY SUNDAY AND MONDAY.

&&

.DISCUSSION...
WITH THE EXTENSION OF THE EASTERN PACIFIC UPPER HIGH INCHING
CLOSER TO NEW MEXICO...THE DRIER AIR COMETH. THE DRYING OF SURFACE
DEWPOINTS AND PRECIPITABLE WATER VALUES HAS BEEN ADVERTISED TO
INVADE WESTERN NM TODAY...AND THIS MORNING'S MODEL RUNS ARE EVEN
MORE AGGRESSIVE WITH THIS DRY PUNCH. THE INTERFACE OF THIS DRY AIR
MEETING UP WITH THE REMNANT MOIST AIRMASS WILL ESTABLISH ITSELF
WEST OF THE RIO GRANDE EARLY IN THE AFTERNOON...LIKELY MIXING TO
THE SPINE OF THE CENTRAL MOUNTAIN CHAIN BY DAY'S END. THIS WILL BE
WHERE A FEW VIRGA SHOWERS OR PERHAPS DRY THUNDERSTORMS COULD
DEVELOP THIS AFTERNOON. FARTHER EAST...ISOLATED TO SCATTERED
SHOWERS AND STORMS WILL BE THE RULE. TEMPERATURES WILL RISE A FEW
DEGREES IN THE DRIER ATMOSPHERE WITH LESS CLOUD COVER.

A FAIRLY SIMILAR STORM COVERAGE PATTERN IS EXPECTED ON THURSDAY
WITH CELLS BEING MOST CONCENTRATED ALONG AND JUST EAST OF THE
CENTRAL MOUNTAIN CHAIN AND VIRTUALLY NO DEVELOPMENT ANTICIPATED TO
THE WEST. TEMPERATURES BY THURSDAY AFTERNOON WILL BE 5 TO 10
DEGREES ABOVE NORMAL IN CENTRAL TO WESTERN ZONES AND CLOSER TO
NORMAL IN THE EASTERN PLAINS OF NM.

THE SURFACE PRESSURE GRADIENT STARTS TO TIGHTEN A BIT THURSDAY
NIGHT WITH HIGH PRESSURE TO THE LEE OF THE MOUNTAINS. THIS WILL
INDUCE AN EASTERLY SYNOPTIC WIND COMPONENT THAT COULD ADVECT SOME
OF THE HIGHER DEWPOINTS OVER THE PLAINS INTO THE CENTRAL PARTS OF
THE STATE BY FRIDAY MORNING. SOME SHOWERS AND STORMS COULD
DEVELOP IN THIS INCREASED MOISTURE FIELD WITH SUFFICIENTLY STEEP
TEMPERATURE LAPSE RATES TO SUPPORT GROWTH. NAM IS SOMEWHAT OF AN
OUTLIER TO BE PICKING UP ON THIS...BUT IT SEEMS VERY
PLAUSIBLE...SO SOME ISOLATED TO SCATTERED COVERAGE WAS INTRODUCED
OVER THE RIO GRANDE TO THE CONTINENTAL DIVIDE. TEMPERATURES STAY
ABOVE NORMAL FRIDAY...BUT DO NOT NECESSARILY RISE ANY HIGHER THAN
THE PREVIOUS DAY.

THE MOISTURE WOULD LIKELY RETREAT BACK EAST ON SATURDAY WITH LESS
STORM COVERAGE OVERALL DUE TO THE DRYING AND SUBSIDENCE FROM THE
APPROACHING UPPER HIGH. WITH THE DOME OF HIGH PRESSURE BUILDING
OVERHEAD ON SUNDAY AND MONDAY...TEMPERATURES WILL RISE A FEW MORE
DEGREES ABOVE AVERAGE. AT THIS TIME THERE DOES NOT APPEAR TO BE
ANY RECORD BREAKING HEAT...BUT THESE WILL BE THE HOTTEST
TEMPERATURES THUS FAR THIS YEAR.

52

&&

.FIRE WEATHER...
AN OVERALL DRYING AND WARMING TREND...WITH SOME RELATIVELY MINOR
SUBTLETIES...STILL EXPECTED TODAY AND GENERALLY THROUGH THE
WEEKEND. DESPITE SOME RECOVERY INTO THE RGV AND TO THE CONTDVD
DURING THE NIGHT...LOW LEVEL MOISTURE IS EXPECTED TO MIX OUT
DURING THE DAY TODAY. AS CAN OCCUR THIS TIME OF YEAR UNDER A RIDGE
OF HIGH PRESSURE ALOFT...IT MAY SLOSH BACK AND FORTH THURSDAY INTO
FRIDAY...AND COULD SEEP BACK INTO THE RGV AT TIMES DURING THE LATE
AFTERNOONS AND EVENINGS.

MODELS HAVE COME DOWN EVEN MORE WITH DEWPOINT FORECAST FOR THIS
AFTERNOON AND THURSDAY IN THE WEST. NAM TRIES TO SLOSH LOW LEVEL
MOISTURE BACK INTO THE RGV LATE THURSDAY AND FRIDAY...AND BOUGHT
INTO THIS AT LEAST PART WAY WITH DEWPOINT AND WIND FORECAST...AS IT
APPEARS SOME CONVECTION MAY DRIFT OFF THE MTS AND HUG THE EAST
SLOPES OF THE SANGRE DE CRISTOS IN THE UPPER HIGH CIRCULATION. IN
ANY EVENT...FORECAST MIN RH FOR THE WEST AND CENTRAL LESS THAN 10
PERCENT THURSDAY...SATURDAY AND SUNDAY...WITH A SLIGHT UPTICK
FRIDAY. OVERNIGHT RECOVERIES FAR WEST WILL BE POOR...AND IMPROVE
FARTHER EAST OF THE CENTRAL MT CHAIN.

WITH THE DRYING...HIGH HAINES WILL BE COMMON THROUGH THE WEEKEND AND
FORECAST HIGHS WILL BE ABLE TO SOAR TO ABOVE AVERAGE VALUES FOR THE
LATTER HALF OF JUNE...WHICH MEANS MANY LOWER TERRAIN AREAS WILL SEE
PREDOMINANTLY 90S TO LOWER 100S FOR HIGHS THURSDAY THROUGH THE
WEEKEND. WINDS WILL BE LIGHT HOWEVER...WITH THE EXCEPTION OF IN THE
VICINITY OF ANY CONVECTION THAT MANAGES TO DEVELOP. THAT WILL BE
MAINLY FROM THE CENTRAL MT CHAIN EASTWARD...ALTHOUGH ISOLATED
CONVECTION COULD SHIFT A BIT WESTWARD FRIDAY. SOME DRY CONVECTION IS
POSSIBLE TODAY FROM THE CONTDVD TO THE RGV. WETTING RAINFALL CHANCES
TAPER DOWN TO LITTLE OR NONE OVER THE WEEKEND THEN RAMP UP AROUND
THE MIDDLE OF NEXT WEEK...WITH MODELS SUGGESTING MOISTURE MAY RETURN
BY WAY OF SURFACE FRONTS OR FROM THE SOUTH.

GOOD TO EXCELLENT VENT RATES FAVOR THE CENTRAL AND WEST TODAY
THROUGH THURSDAY WITH IMPROVEMENT OVERALL ON FRIDAY.

.ABQ WATCHES/WARNINGS/ADVISORIES...
NONE.
