DISCUSSION
ISSUED AT 1135 AM MDT FRI JUL 10 2026
AN ELONGATED UL HIGH EXTENDS FROM OFF THE COAST OF BAJA/SOCAL TO
NM WITH LOW-AMPLITUDE, ZONAL FLOW ACROSS THE REST OF THE CONUS. A
SUBTROPICAL/MONSOONAL PLUME OF MOISTURE IS ON THE EAST SIDE OF THE
HIGH,EXTENDING UP THROUGH NORTHERN MEX INTO THE SOUTHERN HALF OF
NM AND FAR WEST TEXAS. THERE ARE ALSO A FEW SMALL SWIRLS NOTED ON
WV. DEWPOINTS ACROSS THE CWA GENERALLY RANGE 45-55, SO THERE IS
ENOUGH MOISTURE FOR THUNDERSTORMS THIS AFTERNOON AND EVENING.
STORMS WILL START OFF IN THE MOUNTAINS BEFORE N TO NE'LY FLOW
CARRIES THEM SOUTH AND SOUTHWEST INTO THE LOWLANDS. GIVEN THE
DEGREE OF MOISTURE AND WARMTH FROM HIGH PRESSURE ALOFT, COVERAGE
WILL BE SCATTERED IN THE MOUNTAINS AND ISOLATED TO POSSIBLY
SCATTERED IN THE LOWLANDS WITH THE GREATEST COVERAGE WEST OF THE
RIO GRANDE VALLEY. FIFTY TO 60 DEGREE T-TD SPREADS SUGGEST GUSTY
OUTFLOWS WILL BE THE MAIN CONCERN WITH AREAS OF BLOWING DUST. SPC
HAS AREAS NEAR THE AZ BORDER WITH A MARGINAL RISK FOR SEVERE
STORMS. INDEED, THE HRRR SHOWS GUSTS IN EXCESS OF 50 KNOTS. GIVEN
THE SIGNAL FOR STRONG OUTFLOW WINDS AND THE DUST ISSUES WE'VE HAD
ACROSS LUNA AND HIDALGO COUNTIES, A DUST ADVISORY IS IN EFFECT
FROM 3PM TO 8PM THIS AFTERNOON AND EVENING. THUNDERSTORM COVERAGE
WILL GRADUALLY DIMINISH AFTER DARK WITH LOSS OF DAYTIME HEATING.
WE ESSENTIALLY REPEAT TODAY'S PATTERN FOR SATURDAY IN TERMS OF
SENSIBLE WEATHER EXPECTATIONS. THE UL HIGH WILL BE IN TRANSITION,
MOVING TOWARD THE CENTRAL AND NORTHERN PLAINS, REACHING WY/SD/ND
BY SUNDAY. THE NORTHERN PLACEMENT OF THE HIGH WILL OPEN SOUTHERN
NM AND FAR W TX TO A HEALTHY MOISTURE TAP FROM THE GULF OF
MEXICO/AMERICA, AND THAT WILL REMAIN THE CASE FOR MUCH OF NEXT
WEEK. THE WILD CARD WILL BE WHAT AND WHEN INVERTED TROUGHS PUSH
INTO THE AREA AS THESE WILL BRING AN UPTICK IN SHOWER AND
THUNDERSTORM ACTIVITY. MEAN NBM PW VALUES START OFF CLOSE TO AN
INCH TODAY, PEAKING TO AROUND 1.3" BY MONDAY AND TUESDAY WITH A
SLIGHT REDUCTION FOR THE LATTER PART OF NEXT WEEK. THUS, HEAVY
RAIN AND FLASH FLOODING WOULD BE THE MAIN CONCERN WITH ANY STORMS
NEXT WEEK. WITH THE INCREASED MOISTURE AND CLOUD COVERAGE,
AFTERNOON HIGHS WILL DECREASE, DROPPING BELOW NORMAL.
AVIATION
(00Z TAFS)
ISSUED AT 553 PM MDT FRI JUL 10 2026
SHOWERS AND THUNDERSTORMS ONGOING THIS EVENING AND WILL CONTINUE
THE NEXT COUPLE HOURS BUT WILL BE ON THE DOWNTREND AFTER SUNSET.
BIGGEST THREATS CONTINUE TO BE SUDDEN WIND SHIFTS FROM GUSTY
WINDS FROM OUTFLOWS AND BLDU. VCTS POSSIBLE FOR ALL TERMINALS
EXCEPT KTCS, BUT MAYBE SOME SPRINKLES WILL BE POSSIBLE AT KTCS
TONIGHT. CALM AND QUIET CONDITIONS OVERNIGHT. ANOTHER ROUND OF
THUNDERSTORMS TOMORROW ACROSS THE AREA.
FIRE WEATHER
ISSUED AT 1135 AM MDT FRI JUL 10 2026
WE CONTINUE IN A HOT AND RELATIVELY DRY PATTERN FOR TODAY AND
SATURDAY, BUT THERE WILL BE ENOUGH MOISTURE FOR SCATTERED MOUNTAIN
AND ISOLATED LOWLAND STORMS. GUSTY WINDS ALONG WITH A LOW RISK FOR
DRY LIGHTNING WOULD BE THE MAIN CONCERNS. MIN RH VALUES WILL RANGE
FROM THE MIN TO UPPER TEENS IN THE LOWLANDS. WINDS, APART FROM
THUNDERSTORMS, WILL BE LIGHT, TOPPING OUT NEAR 10 MPH. AS WE GO
INTO SUNDAY AND INTO NEXT WEEK, MOISTURE WILL INCREASE WHILE
AFTERNOON HIGHS DECREASE. AFTERNOON MIN RH VALUES WILL ONLY DROP
INTO THE MID AND UPPER 20S. THUNDERSTORM CHANCES, INCLUDING A
THREAT FOR HEAVY RAINFALL AND FLASH FLOODING, WILL ALSO INCREASE.
