555 PM MDT SUN JUL 20 2014

.AVIATION...
00Z TAF CYCLE
ISOLATED TO SCATTERED SHOWERS AND THUNDERSTORMS TO FAVOR WESTERN AND
CENTRAL AREAS THROUGH ABOUT 03Z WITH A FEW DEVELOPING BETWEEN 03Z
AND 06Z OVER THE EAST. UNCERTAINTY IN THE ABQ AREA WITH THUNDERSTORMS
CURRENTLY TO THE SOUTHWEST OF KABQ MOVING NORTH...THUS THINKING THAT
THE CHANCES ARE GREATER AT KAEG THAN AT KABQ. HOWEVER WELL DEFINED
BOUNDARIES ARE MOVING TOWARD KABQ FROM THE SOUTHWEST AND NORTHEAST
AND THUNDERSTORMS COULD DEVELOP AS THE BOUNDARIES INTERSECT. WILL
MONITOR FOR NOW. OUTSIDE OF CONVECTION...VFR CONDITIONS AND GENERALLY
LIGHT WINDS WITH PERSIST THROUGH AROUND 18Z MONDAY. THUNDERSTORMS
TO DEVELOP OVER THE HIGHER TERRAIN AND CENTRAL HIGHLANDS THEREAFTER...
WITH LOCAL MVFR CIGS AND VSBYS AND OCCASIONAL MOUNTAIN OBSCURATIONS...WITH
BEST CHANCES FOR THUNDERSTORMS LIKELY AROUND KLVS.

.PREV DISCUSSION...311 PM MDT SUN JUL 20 2014...
.SYNOPSIS...
SLOW MOVING SHOWERS AND THUNDERSTORMS WITH LOCALLY HEAVY RAINFALL
WILL CONTINUE THROUGH TUESDAY FOR PORTIONS OF CENTRAL AND EASTERN
NEW MEXICO. THE COVERAGE OF THIS ACTIVITY WILL BE MORE ISOLATED IN
NATURE THAN RECENT WEEKS. A STRONG AREA OF HIGH PRESSURE WILL THEN
SHIFT OVER THE STATE WEDNESDAY AND BRING THE HOTTEST TEMPERATURES
IN QUITE A WHILE FOR CENTRAL AND WESTERN NEW MEXICO. MANY LOWER
ELEVATION AREAS WILL TOP OUT IN THE MID 90S TO LOW 100S. THE HIGH
WILL THEN SHIFT WEST AND ALLOW SEVERAL MOIST BACK DOOR FRONTS TO
SHIFT WESTWARD INTO THE STATE. THIS WILL TAPER OFF THE HEAT AND
INTRODUCE ANOTHER ROUND OF MORE SCATTERED THUNDERSTORMS FRIDAY INTO
THE WEEKEND.

&&

.DISCUSSION...
FORECAST CONFIDENCE FOR THIS EVENING IS VERY LOW BUT WITH MODERATE
POTENTIAL IMPACT. SHORT-TERM MODEL GUIDANCE IS ALL OVER THE PLACE
WITH RESPECT TO PLACEMENT OF CONVECTIVE FEATURES THIS EVENING. THE
20Z SURFACE DEWPOINT VALUES ARE CRATERING OVER MUCH OF THE REGION
DESPITE ABUNDANT MID AND UPPER LEVEL MOISTURE. THE BEST MOISTURE IS
POOLING AROUND THE MIDDLE RIO GRANDE VALLEY AND OVER THE SE PLAINS.
THE LATEST HRRR AND 12Z GFS ARE PICKING UP ON A CONVECTIVE COMPLEX
MOVING FROM THE DIVIDE TO NEAR THE ABQ METRO THIS EVENING. THE 06Z
WRF AND NAM GUIDANCE SHOWED THIS EARLIER BUT BACKED OFF ON IT FOR
THE 12Z RUN. QPF VALUES COULD BE HIGH BENEATH A SLOW MOVING SOUTH
TO NORTH COMPLEX BUT PLACEMENT AND DURATION IS VERY QUESTIONABLE.
PLACED CHANCE POPS OVER A LARGE AREA OF CENTRAL NM AS A RESULT. THE
OTHER WRINKLE IS THE HRRR SHOWS A LARGE AREA OF PRECIP SHIFTING
NORTH AFTER 06Z UP THE LOWER RIO GRANDE VALLEY. WOULD NOT BE
SURPRISED TO SEE THIS OCCUR AS THE LATEST IR SHOWS SOME VIGOROUS
CONVECTION ERUPTING OVER NORTH CENTRAL MEXICO.

THE GFS ENSEMBLE AND SREF SHOW WITH VERY GOOD AGREEMENT THE CURRENT
594DM H5 HIGH CENTERED OVER SOUTHEAST NM SHIFTING NORTH MONDAY AND
TUESDAY AND BUILDING TO 599DM OVER SOUTHERN COLORADO. THIS INTRODUCES
ANOTHER TOSS UP AS HEIGHTS RISE WELL ABOVE NORMAL BUT AN AXIS OF MID
LEVEL MOISTURE ROTATES WEST FROM WEST/CENTRAL TX. SEVERAL DAYS AGO
MODELS WERE CONSERVATIVE WITH CONVECTIVE DEVELOPMENT BUT TRENDS HAVE
BEEN FOR MORE COVERAGE...PARTICULARLY TUESDAY. MADE ONLY SUBTLE POP
CHANGES TO INCREASE VALUES OVER THE PLAINS. OTHERWISE...EXPECT AT
LEAST HOT TEMPS.

BEYOND WEDNESDAY THE UPPER HIGH WILL TREND TOWARD THE WEST WHILE YET
ANOTHER VERY STRONG SUMMER UPPER LOW SLIDES INTO THE GREAT LAKES.
THE TRANSITION PERIOD FOR THURSDAY/FRIDAY IS ALSO LOW CONFIDENCE
DEPENDING ON HOW THE HIGH WARPS AND DRIFTS WESTWARD. A STRONG BACK
DOOR FRONT IS THEN DEPICTED SATURDAY THROUGH EARLY NEXT WEEK AS A
FOCUS MECHANISM FOR MORE CONVECTION OVER NM. THIS IS MOST CERTAINLY
NOT ANYWHERE NEAR THE TYPE OF PATTERN THAT ONE WOULD EXPECT TO SEE
OVER THE CONUS DURING LATE JULY.

.FIRE WEATHER...
WHILE TODAYS SHOWER AND STORM CROP HAS BEEN A SLOW STARTER...IT MAY
END UP TO BE NEARLY AS GOOD OR BETTER COVERAGE IN CENTRAL AND
SOUTHERN PORTIONS OF THE FORECAST AREA BY LATE AFTN OR EVE. THE BULK
OF THE BURN SCAR AREAS WILL CONTINUE TO HAVE SOME RISK OF HEAVY
RUNOFF OR WORSE THROUGH THE EVE. THE AMOUNT AND LOCATION OF THE
MAXIMUM SHOWER AND THUNDERSTORM ACTIVITY WILL VARY A FAIR DEGREE
FROM DAY TO DAY ACROSS THE NEXT 5 TO 7 DAYS...PROBABLY SHIFTING A
LITTLE WAYS TO THE EAST AND SOUTH MON AND THEN BACK TO THE WEST AND
NORTH TUE AND WED. IT BECOMES A LITTLE LESS CERTAIN THEREAFTER...AS
TO LOCATION AND DEGREE OF COVERAGE...BUT LONGER RANGE FORECAST MODEL
DATA SEEMS TO AGREE PRETTY WELL THAT A MODERATE TO STRONG BACK DOOR
COLD FRONT FOR THIS TIME OF YEAR WILL PUSH INTO AND ACROSS AT LEAST
EAST AND CENTRAL NM AND PERHAPS EVEN FARTHER WEST SAT NIGHT INTO
SUN. THIS SHOULD GENERATE A MODERATE TO ROBUST INCREASE IN SHOWERS
AND STORMS NEAR AND BEHIND ITS PASSAGE BETWEEN LATE SAT AND MON.
UNTIL THEN HOWEVER...ABOVE NORMAL TEMPERATURES AND AT LEAST SLIGHTLY
BELOW NORMAL THUNDERSTORM ACTIVITY FOR MID TO LATE JULY CAN BE
EXPECTED DUE TO A DOMINANT UPPER HIGH OVER THE REGION.

NO CRITICAL WIND SPEEDS ARE EXPECTED OVER THE NEXT 5 TO 7 DAYS AT
LEAST...COMMON FOR THIS TIME OF YEAR...BUT MINIMUM RHS HAVE REACHED
MARGINALLY CRITICAL LEVELS ACROSS A FEW SITES ACROSS NORTH NM AND
EVEN THE LOWER RIO GRANDE VALLEY. THIS MAY EXPAND SOMEWHAT BETWEEN
MON AND WED...BUT SUBSIDE SOME AGAIN BY LATE WEEK OR THE WEEKEND
HAINES INDICES ARE FORECAST TO TREND UP SOME MON AND PERHAPS
TUE...THEN DROP SOME WED AND THU BEFORE TRENDING BACK UP NEAR END OF
WEEK. OVERNIGHT RH RECOVERIES WILL VARY FROM FAIR TO VERY
GOOD...DEPENDING IN LARGE PART ON WHERE THE MORE SIGNIFICANT
RAINFALL HAS FALLEN ON A PARTICULAR DAY.
