DISCUSSION
ISSUED AT 1035 PM MDT FRI SEP 4 2026
A LARGE UL RIDGE IS COVERING MUCH OF THE CONUS WITH ITS CENTER
JUST OFF THE GULF COAST OF TX AND LA. THIS PATTERN HAS STEERED A
RICH MOISTURE PLUME OUR WAY WITH THE 00Z EPZ SOUNDING SHOWING
1.56" OF PW. LACK OF UL FORCING (POSSIBLY EVEN A LITTLE BIT OF
BACKGROUND SUBSIDENCE) AND MORNING CLOUD COVERAGE DID A GOOD JOB
OF LIMITING CONVECTIVE COVERAGE THIS AFTERNOON, ESPECIALLY ALONG
AND EAST OF THE RIO GRANDE. SATELLITE IMAGERY HINTS AT A WEAK
DISTURBANCE OVER NORTHERN CHIHUAHUA, WHICH WILL SLOWLY LIFT NORTH
OVERNIGHT TONIGHT AND INTO THE MORNING. GUIDANCE IS NOT
PARTICULARLY HELPFUL ON WHETHER THIS DISTURBANCE WILL BRING
SHOWERS AND STORMS NORTH OF THE BORDER. THE HRRR HAS GIVEN A
DIFFERENT SOLUTION WITH EVERY ITERATION. NEVERTHELESS, IT WILL
BRING CLOUDS, AND THAT MAY WORK TO HINDER OUR STORM CHANCES AGAIN
FOR SATURDAY. REGARDLESS, OUR PATTERN LOOKS TO BE LARGELY THE SAME
OTHERWISE, VERY MOIST (~1.5" PW) WITH THE WESTWARD EXTENSION OF
THE RIDGE OVERHEAD, SO EXPECT A FORECAST SIMILAR TO TODAY WITH
SCATTERED MOUNTAIN STORMS AND ISOLATED TO SCATTERED COVERAGE IN
THE LOWLANDS, LARGELY DEPENDING ON HOW MUCH CLOUD/RAIN LINGERS
INTO THE MORNING. HEAVY RAIN WILL BE THE MAIN CONCERN.
BY SUNDAY WE BEGIN A SLOW DRYING TREND AS THE SUBTROPICAL RIDGE'S
INFLUENCE INCREASES OVER THE CWA. PW VALUES WILL DROP TO AROUND
1.25" WITH H500 TEMPS AROUND -4 DEGREES C. CONVECTIVE COVERAGE
WILL DROP, ESPECIALLY FOR THE LOWLANDS, BUT EVERYONE WILL CONTINUE
TO SEE AT LEAST MODEST RAIN/STORM CHANCES WITH MOUNTAINS AND
WESTERN LOWLANDS FAVORED, AND THIS PATTERN WILL HOLD STEADY
THROUGH AT LEAST THE MIDDLE OF NEXT WEEK. THE UL HIGH WILL
CONTINUE TO EXTEND ITS INFLUENCE INTO NM WITH THE HEALTHIEST
MOISTURE PLUME WEST OF THE CONTINENTAL DIVIDE. AS WE GET INTO
WEDNESDAY AND BEYOND THE GFS AND EURO DIVERGE WITH THE EURO
BUILDING THE RIDGE OVER THE DESERT SW WITH MOISTURE TRAPPED
BENEATH IT WHILE THE GFS SENDS THE RIDGE WELL TO OUR EAST WITH A
TROUGH INFLUENCING OUR WEATHER. THE EURO WOULD CONTINUE THIS
PATTERN OF SCATTERED MOUNTAIN AND ISOLATED LOWLAND STORMS WHILE
THE GFS WOULD BRING WIDESPREAD RAIN/STORM CHANCES. LOOKING AT THE
LREF 500 MB HEIGHTS, I'D SAY THE TRUTH WILL LIE SOMEWHERE IN THE
MIDDLE THOUGH PROBABLY MORE RIDGY THAN TROUGHY (NOT A REAL WORD).
TEMPERATURES THROUGHOUT THE PERIOD LOOK TO MORE OR LESS HOLD
STEADY, RUNNING ABOUT 5 DEGREES ABOVE NORMAL, WHICH IS UPPER THE
80S TO NEAR 90 THIS TIME OF YEAR FOR THE LOWLANDS.
AVIATION
(06Z TAFS)
ISSUED AT 1035 PM MDT FRI SEP 4 2026
MOSTLY VFR CONDITIONS WILL CONTINUE WITH VARIABLE SKIES WITH BASES
AROUND 100. OTHERWISE, IT IS A BIT OF A LOW CONFIDENCE FORECAST,
ESPECIALLY THROUGH 12Z. RADAR SHOWS A CLUSTER OF SHOWERS AND
STORMS OVER MEXICO, AND FORECAST GUIDANCE HAS BEEN UNHELPFUL IN
DETERMINING HOW FAR NORTH THESE STORMS WILL MOVE, INCLUDING IF
THERE WILL BE ANY IMPACTS AT ELP.
AFTER 18Z, ADDITIONAL SHRA/TSRA IS EXPECTED TO DEVELOP, BUT
CONFIDENCE ON TIMING AND OCCURRENCE HAS PRECLUDED MENTION OF TSRA
IN TAF SITES.
OUTSIDE OF STORMS, WINDS WILL BE LIGHT, MOSTLY FROM THE SW AT ELP
AND W TO NW AT OTHER SITES WITH SPEEDS UNDER 10 KNOTS.
FIRE WEATHER
ISSUED AT 1014 AM MDT FRI SEP 4 2026
FIRE WEATHER CONCERNS WILL BE LOW THROUGH THE MIDDLE OF NEXT WEEK.
FOR THIS AFTERNOON, STORM CHANCES WILL BE LIMITED TO AREA MTNS WITH
STORM MOTION TO THE NE AS CLOUDS SLOWLY ERODE. ANY STORMS THAT
DEVELOP WILL BE CAPABLE OF PRODUCING HIGH RAIN RATES AND GUSTS TO 30
MPH. PREVAILING WINDS WILL BE LIGHT FROM THE W-SW TODAY. BETTER
STORM COVERAGE IS FORECAST FOR THE LOWLANDS TONIGHT, FAVORING FAR
WEST TX. OVERNIGHT RECOVERIES WILL BE VERY GOOD TO EXCELLENT.
FOR SAT, ISOLATED STORM COVERAGE IS EXPECTED DEPENDING ON HOW MUCH
CLOUDS STICK AROUND IN THE AM. GUSTY OUTFLOW WINDS AND BRIEF
DOWNPOURS ARE THE MAIN THREATS FOR SAT. LIGHT AND VARIABLE WINDS
EXPECTED OTHERWISE. FROM SUN ONWARD, STORM CHANCES AND HEAVY
RAINFALL FAVOR WESTERN AREAS WITH MORE ISOLATED COVERAGE ELSEWHERE.
MOISTURE LEVELS REMAIN ABOVE NORMAL FOR EARLY SEP NEXT WEEK. WINDS
STAY LIGHT, SHIFTING MORE E-SE THIS WEEKEND.
MIN RHS RANGE FROM 25-35% IN THE LOWLANDS INTO NEXT WEEK, 35-60% IN
THE MTNS. VENT RATES WILL BE POOR TO GOOD THROUGH SAT, THEN MOSTLY
FAIR TO GOOD.
