DISCUSSION
ISSUED AT 958 PM MDT SUN AUG 30 2026
WESTERN AREAS WILL REMAIN FAVORED FOR STORMS TONIGHT AND ON
MONDAY AS THE MONSOON HIGH SHIFTS EAST OVER THE MID-MS RIVER
VALLEY. CAMS SHOW ISOLATED TO SCATTERED CONVECTION REDEVELOPING
OVERNIGHT ALONG THE AZ-NM BORDER BEFORE PUSHING NORTH BY MON AM.
PWS INCREASE A BIT ON MON AREA-WIDE (1-1.1" FOR KELP) AS THE
HEAVY RAIN THREAT PERSISTS W OF THE DIVIDE, MAINLY IN THE
BOOTHEEL. THERE IS SOME FORCING TOMORROW WITH A SHORTWAVE MOVING
INTO THE FOUR CORNERS WITHIN SW FLOW ALOFT. ISOLATED SHOWERS AND
STORMS ARE FORECAST DURING THE AFTERNOON FOR MUCH OF THE
LOWLANDS, INCLUDING EL PASO AND LAS CRUCES, WITH DRIER CONDITIONS
OUT EAST. A SFC CONVERGENCE ZONE LOOKS TO DEVELOP IN THE EVENING
NEAR THE RGV (BETTER SE FLOW TO THE EAST AND W FLOW TO THE WEST).
THIS COULD SPARK SCATTERED SHOWERS AND STORMS MON NIGHT AS
REFLECTED BY SEVERAL HRRR RUNS, PROGRESSING NORTHWARD BEFORE
FIZZLING TUE AM.
GLOBAL MODELS ARE IN AGREEMENT WITH THE UPPER HIGH FOCUSING OVER THE
CAROLINAS/TN VALLEY THROUGH MIDWEEK AND STRETCHING ACROSS THE
SOUTHERN PLAINS, KEEPING MUCH OF THE MONSOONAL MOISTURE SOUTH AND
WEST OF US. LOW MTN STORM CHANCES ARE FORECAST FROM TUE ONWARD AS
THE LOWLANDS STAY MAINLY DRY. WESTERN AREAS WILL BE FAVORED FOR
STORMS AND ISOLATED HEAVY RAINFALL THROUGH MIDWEEK.
THE HIGH LOOKS TO CENTRALIZE OVER THE CENTRAL/SOUTHERN PLAINS INTO
NEXT WEEKEND AND REINVIGORATE THE MOISTURE PLUME. AREAS TO THE
WEST APPEAR BEST SET UP FOR STORM CHANCES AND HEAVY RAINFALL TO
END THE PERIOD. FOR MUCH OF THE AREA, PWS LOOK TO BE SLIGHTLY
ABOVE NORMAL FOR NEXT WEEKEND WITH POTENTIAL INTRODUCTION OF
TROPICAL MOISTURE FROM A PACIFIC SYSTEM. THE PLACEMENT OF THE HIGH
WILL DETERMINE HOW MUCH MOISTURE GETS SCOOPED UP INTO THE REGION,
BUT BETTER RAIN CHANCES OVERALL ARE ANTICIPATED.
TEMPS WILL BE STEADY THROUGH THE WEEK WITH HIGHS 4-8 DEGREES
ABOVE NORMAL. LOWLAND HIGHS OF 95-100F ARE FORECAST EACH DAY WITH
SLIGHT COOLING ON TUE BEHIND THE SHORTWAVE. WINDS REMAIN LIGHT
THROUGH THE WEEK MAINLY FROM THE W.
AVIATION
(06Z TAFS)
ISSUED AT 958 PM MDT SUN AUG 30 2026
ISOLATED TS DEVELOP IN THE AFTERNOON, FAVORING KDMN AND KTCS WITH
~20% CHANCES. CONFIDENCE IS TOO LOW FOR ANY TS MENTION IN TAFS.
ADDITIONAL SHOWERS AND STORMS MAY DEVELOP LATE IN THE PERIOD FROM
KELP TO KTCS. GUSTS TO 30KTS FROM OUTFLOWS ARE POSSIBLE AFTER
20Z. OTHERWISE, WINDS AOB 10KTS FROM S AND W.
FIRE WEATHER
ISSUED AT 122 PM MDT SUN AUG 30 2026
UPPER LEVEL RIDGING WILL SLOWLY NUDGE EASTWARDS AS A TROUGH DIGS
IN OVER THE WEST COAST. THIS WILL SEND SOME INCREASING MOISTURE
OUT WAY, BUT WITH VARIABLE PRECIPITATION CHANCES THAT FAVOR
SOUTHWESTERN NEW MEXICO. TEMPERATURES WILL EASE UP A BIT, FALLING
TO NEAR NORMAL WEST OF THE DIVIDE, AND ABOUT 5 DEGREES ABOVE
NORMAL CLOSER TO THE RIO GRANDE. THE RIDGE WILL ATTEMPT TO REBUILD
ON WEDNESDAY, BUT PRECIP CHANCES LOOK BETTER LATE IN THE WEEK AS
TROUGHING NUDGES IN FROM THE WEST AGAIN.
MIN RH VALUES WILL AROUND 15 PERCENT IN THE LOWLANDS, AND 20 TO 25
PERCENT IN THE HIGHER ELEVATIONS THIS AFTERNOON AND AGAIN ON
MONDAY. EXPECT SLIGHT IMPROVEMENTS THROUGH THE WEEK AHEAD.
