.PREV DISCUSSION...330 AM MDT MON MAY 25 2015...
.SYNOPSIS...
A WARMING TREND WILL START TODAY AND CONTINUE FOR THE NEXT COUPLE OF
DAYS. HOWEVER...TODAY WILL SEE MORE SHOWERS AND STORMS FAVORING THE
NORTH AND WEST BEFORE THE UPPER LOW OVER COLORADO LIFTS INTO THE
UPPER MIDWEST. DRIER TUESDAY AND INTO WEDNESDAY THEN SHOWERS AND
STORMS WILL BECOME MORE WIDESPREAD EAST AND CENTRAL WEDNESDAY NIGHT
THROUGH THE REST OF THE WEEK DUE TO SURGES OF LOW LEVEL MOISTURE
INTO THE REGION.

&&

.DISCUSSION...
SHOWERS DIMINISHING EARLY THIS MORNING AS ONE WAVE EXITS...BUT ANOTHER IS
UPSTREAM AND POISED TO START ANOTHER CYCLE OF INCREASING SHOWERS AND
STORMS WEST AND NORTH FOR TODAY. MODELS HAVE TAKEN THIS INCOMING WAVE
PROGRESSIVELY FARTHER SOUTH...SO STRETCHED AT LEAST SLIGHT CHANCE POPS
OVER THE ENTIRE CWA. GENERAL THEME FOR TUESDAY IS DRIER...AND POPS LIMITED
TO MAINLY MTS. WEDNESDAY WILL REMAIN MOSTLY DRY WEST BUT AS A TREND TOWARD
SLY FLOW DEVELOPS AHEAD OF AN INCOMING TROUGH...THE SOUTH CENTRAL AND
SOUTHEAST WILL SEE INCREASING CHANCES FOR CONVECTION...ESPECIALLY
WEDNESDAY NIGHT. FOR NOW IT APPEARS ANY STRONG TO SEVERE STORMS WILL STAY
TO OUR NORTHEAST WEDNESDAY.

THURSDAY INTO SATURDAY WILL FEATURE BEST CHANCES FOR CONVECTION CENTRAL AND
EAST...AS THE UPPER TROUGH PASSES AND A STRONGER FRONT PUSHES INTO THE
EASTERN PLAINS. THE GFS SEEMS SLOWER WITH THE FRONT THAN 24 HRS AGO. EARLY
NEXT WEEK LOOKS DRY AND POSSIBLY WINDY...BUT THE TROPICAL SYSTEM IS STILL A
FIXTURE NEXT WEEK...AND GFS PUSHES SOME MOISTURE UP TOWARDS THE BOOTHEEL
FROM IT. NEW ECMWF SIMILAR BUT SLOWER BY A DAY.

&&

.FIRE WEATHER...
UPPER LEVEL SHORTWAVE OVER SOUTHERN NM THIS MORNING WILL EXIT
EASTWARD...BUT ADDITIONAL ENERGY WILL SWING INTO NORTHWEST
NM TODAY. AS A RESULT...SHOWERS AND THUNDERSTORMS WILL DEVELOP OVER
THE NORTHWEST HALF OR SO OF THE AREA THIS AFTERNOON. WETTING RAINS
MAY BE MORE SPOTTY. ELSEWHERE...WINDS MAY BE BREEZY...ESPECIALLY
ACROSS THE CENTRAL HIGHLANDS. WINDS WILL DIMINISH AFTER SUNSET...AND
GOOD TO EXCELLENT RELATIVE HUMIDITY RECOVERIES ARE EXPECTED.

ZONAL FLOW IS EXPECTED ON TUESDAY...AND OVERALL...SHOWER AND
THUNDERSTORM ACTIVITY WILL BE LESS THAN TODAY. STILL EXPECTING
STORMS OVER THE NORTHERN MOUNTAINS...AND PERHAPS THE EAST SLOPES OF
THE SANGRE DE CRISTO MTNS IF A WEAK WIND SHIFT NUDGES UP TO THE
AREA. OTHERWISE...HUMIDITIES WILL TREND DOWNWARD...BUT WILL STAY
ABOVE 20 PERCENT FOR MOST AREAS.

AS THE NEXT SYSTEM APPROACHES NM FROM THE WEST ON WEDNESDAY AND WED
NIGHT...LOW LEVEL SOUTH TO SSELY FLOW ACROSS THE PLAINS WILL DRAW UP
GULF MOISTURE ONCE AGAIN...AND MAY RESULT IN STORMS ACROSS THE EAST
CENTRAL PLAINS AS EARLY AS WED EVE. AS THE UPPER LEVEL SYSTEM MOVES
ACROSS NM ON THURSDAY...MORE CONVECTION IS EXPECTED FROM THE CENTRAL
MTN CHAIN EASTWARD. MEANWHILE...MUCH DRIER AIR SHOULD FILTER INTO
WESTERN AND PERHAPS CENTRAL NM WED AND THURS. IN FACT...DAYTIME
HUMIDITIES SHOULD FALL BELOW 15 PERCENT. THOUGH WINDS WILL BE
BREEZY...ESPECIALLY WED...THEY WILL REMAIN BELOW CRITICAL CRITERIA.
NONETHELESS...HAINES VALUES OF 6 ARE EXPECTED EACH DAY.

ANOTHER BACK DOOR COLD FRONT WILL ENTER THE NORTHEAST PLAINS
FRIDAY...AND CONTINUE TO SLIDE SOUTHWARD THRU THE PLAINS FRIDAY
NIGHT. IT LOOKS LIKE IT WILL PUSH THRU THE GAPS OF THE CENTRAL MTN
CHAIN...IF NOT FRI NIGHT...THEN SAT NIGHT.  OTHERWISE...LOOK FOR
SHOWERS AND THUNDERSTORMS TO CONTINUE ACROSS AT LEAST THE EASTERN
PLAINS.

OTHERWISE...LOOK FOR TEMPERATURES TO REMAIN AT OR BELOW NORMAL FOR
THE NEXT 7 DAYS. WEDNESDAY LOOKS TO BE THE WARMEST DAY WITH MOST
AREAS WITHIN A FEW DEGREES OF NORMAL FOR LATE MAY. VENTILATION WILL
BE GOOD TO EXCELLENT...EXCEPT ON FRIDAY AND SATURDAY ACROSS THE
NORTHEAST WHERE POOR TO FAIR VALUES ARE EXPECTED BEHIND THE FRONT.

&&

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