DISCUSSION
ISSUED AT 145 PM MDT TUE SEP 1 2026
LEFTOVER CONVECTIVE DEBRIS CLOUDS OVER SW NEW MEXICO HAVE MOSTLY
DISSIPATED, EXCEPT AROUND AN MCV IN THE GILA REGION. CONVECTION
HAS BEEN MOSTLY CONFINED TO THE SACRAMENTO MOUNTAINS, THOUGH WE
ARE SEEING SOME BUILDUPS IN THE BOOTHEEL AND EVEN OVER A FEW
DESERT MOUNTAIN RANGES.
STORMS OVER THE SACRAMENTOS HAVE HAD A SMALL FOOTPRINT, BUT HAVE
BEEN TRAINING AND ANCHORED TO THE TERRAIN A BIT. BUT INTENSITY IS
ON THE DOWNTURN. OVERALL, EXPECT FAIRLY ISOLATED THUNDERSTORMS
GOING FORWARD, BUT STILL FAVORING AREAS EAST OF THE RIO GRANDE,
AND MOSTLY SOUTHERN OTERO AND NEAR HIGHER TERRAIN IN HUDSPETH
COUNTY.
MODELS CONTINUE TO SHOW INCREASING MOISTURE FOR TOMORROW (WED),
BUT LOW LEVEL MOISTURE WILL BE LACKING IN NORTHERN AREAS, WITH
PWAT VALUES BY AFTERNOON RANGING FROM AROUND 1.00 INCHES IN
CENTRAL SIERRA COUNTY, TO 1.25 INCHES NEAR THE INTERNATIONAL
BORDER, WHERE MODEST INSTABILITY WILL ALSO BE PRESENT. UPPER
LEVEL SUPPORT WILL BE LIMITED, AS THE UPPER RIDGE WILL BE TRYING
TO REBUILD ITS WESTERN LIMB. BUT, ISOLATED THUNDERSTORMS WILL
STILL BE POSSIBLE, FAVORING SOUTHERN AREAS, AND ESPECIALLY THE
BOOTHEEL.
THURSDAY, PWAT VALUES CONTINUE TO INCREASE AND ADVECT NORTHWARDS.
TROUGHING OVER THE WESTERN US LOOKS TO TRY AND EDGE OUT THE
WESTERN LIMB OF THE RIDGE AGAIN. NO STRONG SHORTWAVE TROUGHS ARE
NOTED, BUT SOME POCKETS OF COOLER MID-LEVEL AIR ARE EVIDENT IN THE
GFS. ALSO, UPPER LEVEL DIFFLUENCE RETURNS AS THE RIDGE HIGH ALOFT
BREAKS DOWN. OVERALL, THURSDAY LOOKS LIKE AN UPTICK IN COVERAGE,
WITH SOUTHWESTERN NEW MEXICO MOST FAVORED IN THE EVENING.
THE SUBTROPICAL RIDGE CONTINUES TO HOLD ALL THE CARDS FOR PRECIP
CHANCES GOING FORWARD. SW NEW MEXICO AND ARIZONA LOOK MORE FAVORED
OVER THE WEEKEND AS THE RIDGE REBUILDS OVER THE AREA YET AGAIN.
BUT, THERE APPEARS TO BE PLENTY OF TRAPPED MOISTURE UNDERNEATH.
BUT 500MB TEMPS OF -3.5 TO -4C ARE NOT FAVORABLE FOR AREAS EAST OF
THE DIVIDE.
TEMPERATURES STILL LOOK TO HOLD BELOW 100 THROUGH THE WEEKEND,
THOUGH EARLY NEXT WEEK IS TRENDING TOWARDS A MORE SPRAWLING RIDGE
AGAIN.
AVIATION
(18Z TAFS)
ISSUED AT 145 PM MDT TUE SEP 1 2026
ISOLATED THUNDERSTORMS NOT COMPLETELY OUT OF THE QUESTION IN THE
LOWLANDS NEAR ELP THIS AFTERNOON, BUT PROBABILITY IS ONLY ABOUT
15-20 PERCENT. OTHERWISE, STORMS LOOK TO MOSTLY STAY OVER HIGHER
TERRAIN AREAS EAST AND NORTHEAST OF ELP. EXPECT GENERALLY LIGHT
WINDS WITH NO WIDESPREAD OUTFLOW LIKE LAST NIGHT. A DOWNTICK IN
THUNDERSTORM COVERAGE IS EXPECTED ON WEDNESDAY, WITH TERMINALS
EXPECTED TO STAY UNAFFECTED.
FIRE WEATHER
ISSUED AT 145 PM MDT TUE SEP 1 2026
ISOLATED SLOW MOVING THUNDERSTORMS OVER THE SACRAMENTO MOUNTAINS
WILL DIMINISH IN THE NEXT COUPLE OF HOURS, WITH VERY LOW COVERAGE
ELSEWHERE. EXPECT SIMILAR LOW COVERAGE ON WEDNESDAY AS UPPER LEVEL
RIDGING TRIES TO BUILD BACK IN. PRECIP CHANCES LOOK TO INCREASE
FROM THURSDAY AS ADDITIONAL MOISTURE AND SOME UPPER LEVEL SUPPORT
MOVES INTO THE PICTURE. PRECIP CHANCES WILL TEND TO SHIFT WESTWARD
THROUGH THE WEEKEND.
TEMPERATURES WILL BE NEAR NORMAL IN SW NEW MEXICO, AND A FEW
DEGREES ABOVE NORMAL EAST OF THE CONTINENTAL DIVIDE. MINRH VALUES
WILL BE ON THE UPSWING AS MOISTURE INCREASES OVER THE NEXT SEVERAL
DAYS.
