SHORT TERM /THROUGH TONIGHT/
ISSUED AT 1216 PM MDT FRI JUL 11 2025
TONIGHT, MULTIPLE ROUNDS OF STORMS ARE EXPECTED TO MOVE THROUGH
THE AREA, ESPECIALLY OUR NORTHWEST AREAS OVERNIGHT INTO SATURDAY
MORNING. GENERALLY, SEVERE WEATHER IS FAVORABLE GIVEN THE
ENVIRONMENTAL CONDITIONS. INSTABILITY RIGHT NOW IS LIKELY THE
BIGGEST LIMITING FACTOR, BUT IT IS ADEQUATE. THE MAIN THREATS
FROM SEVERE WEATHER WILL BE DAMAGING WINDS AND A SECONDARY
THREAT OF LARGE HAIL. AS FAR AS TIMING, THE STORMS LOOK TO BE
APPROACHING OUR WESTERNMOST COUNTIES BY AROUND 00Z TO 01Z AND
PROGRESS EASTWARD THROUGH THE AREA QUICKLY. WE ARE OUTLOOKED IN
A SLIGHT RISK OF SEVERE WEATHER FROM SPC TO REFLECT THIS RISK,
ESPECIALLY FOR OUR NORTHWESTERNMOST AREAS. SOME BLOWING DUST
OUT AHEAD OF THESE STORMS WILL BE A CONCERN AGAIN TONIGHT, BUT
GENERALLY GIVEN THE RAINFALL YESTERDAY SHOULD BE IMPROVED
SLIGHTLY.
ONE LARGE CONCERN FOR ESPECIALLY THE OVERNIGHT HOURS FROM AROUND
10PM-MIDNIGHT MT THROUGH AROUND 6AM MT OR LATER WILL BE THE
FLASH FLOODING THREAT. THIS CONCERN IS MAINLY FOR THE
NORTHWESTERNMOST COUNTIES (YUMA, DUNDY, AND CHEYENNE), BUT COULD
EXTEND TO THE SURROUNDING COUNTIES TO THE EAST AND SOUTH OF
THAT LOCATION GIVEN SOME OF THE UNCERTAINTIES. ENVIRONMENTAL
CONDITIONS IN THIS AREA ARE QUITE FAVORABLE FOR FLASH FLOODING
WITH DECENT MOISTURE UP THE ATMOSPHERIC COLUMN, HIGH PWS, LONG
SKINNY CAPE, AND LOWER SHEAR. THERE IS A SMALL LOW LEVEL JET,
BUT IT IS QUITE WEAK AND IF IT DOES NOT MANIFEST, THIS COULD BE
THE BIGGEST LIMITING FACTOR TOWARD SEEING FLASH FLOODING. FOR
NOW IN RECENT MODELS, IT SEEMS ADEQUATE, BUT WILL NEED TO BE
MONITORED. THERE IS ALSO SOME UNCERTAINTY IN HOW MUCH TRAINING
WILL OCCUR WITH THESE STORMS, BUT RECENT MODEL TRENDS HAVE BEEN
INCREASINGLY HIGHLIGHTING THIS SCENARIO. IF THAT HAPPENS, FLASH
FLOODING IMPACTS WILL BE LIKELY.
LOOKING AT THE MODELS, MULTIPLE ROUNDS OF RAINFALL WILL OCCUR
OVER THE AREA FROM 10/11PM MT THROUGH 6AM MT WITH 2-4" INCHES
EXPECTED. THIS COULD OCCUR OVER THE SAME AREAS, BASED ON RECENT
TRENDS, PRIMARILY FOR YUMA, DUNDY, AND CHEYENNE COUNTIES. THIS
RAINFALL COULD BE FAIRLY EFFICIENT AS WELL WITH 1-1.5" PER HOUR
RAINFALL RATES POSSIBLE. WE ARE OUTLOOKED IN A SLIGHT RISK OF
HEAVY RAINFALL FOR THESE AREAS TO REFLECT THIS RISK. GIVEN THE
FLASHY CREEKS AND RIVERS IN THIS AREA AND GENERAL HILLY TERRAIN,
THIS WILL BE A BIG CONCERN FOR FLASH FLOODING IMPACTS. MINOR TO
MODERATE FLOODING ON RURAL ROADS AND LOW LYING AREAS ARE ALL IN
THE REALM OF POSSIBILITY, ESPECIALLY NEAR CREEKS AND RIVERS. AS
A RESULT, A FLOOD WATCH HAS BEEN ISSUED FOR YUMA, DUNDY, AND
CHEYENNE COUNTIES TO HIGHLIGHT THE RISK AREAS AND POTENTIAL FOR
FLASH FLOODING. WE WILL CONTINUE MONITORING OVERNIGHT. MSW
LONG TERM /SATURDAY THROUGH FRIDAY/
ISSUED AT 1216 PM MDT FRI JUL 11 2025
SATURDAY THROUGH TUESDAY, UPPER LEVEL RIDGING WILL BUILD OVER
THE AREA. CONDITIONS WILL BE FAIRLY DRY OVERALL SATURDAY
AFTERNOON THROUGH TUESDAY AS A RESULT. WINDS WILL BE
PREDOMINANTLY SOUTHERLY. SO FIRE WEATHER CONCERNS SHOULD BE KEPT
TO A MINIMUM WITH RHS WELL ABOVE 20-30%. HIGH TEMPERATURES WILL
BE MILD IN THE MID 90S OVERALL WITH HEAT INDEX VALUES IN THE LOW
90S. GENERALLY, EXPECT SUNNY AND DRY WEATHER EARLY NEXT WEEK.
TUESDAY NIGHT THROUGH THE END OF THE WORKWEEK, MULTIPLE ROUNDS
OF RAINFALL AND SYSTEMS ARE POSSIBLE AS ZONAL FLOW DOMINATES THE
PATTERN AND 1-2 SHORTWAVES COULD INFLUENCE THE AREA. THERE IS
STILL A LOT OF MODEL UNCERTAINTY IN THESE SYSTEMS, ESPECIALLY
SINCE ONE WILL INFLUENCE THE OTHER AS WE GO TOWARD THE WEEKEND.
GENERALLY, LOOKING AT THE CURRENT MODEL TRENDS, ALL MODES OF
SEVERE WEATHER WILL BE POSSIBLE, ESPECIALLY DAMAGING WINDS. AND
FLASH FLOODING COULD ALSO BE A CONCERN IN HILLY OR URBAN AREAS
WHERE RAIN TRAINS OR FALLS MULTIPLE TIMES OVER THE SAME AREA. A
LOT OF WHAT HAPPENS AT THE END OF NEXT WEEK WILL BECOME MORE
CLEAR AS WE GET TO MONDAY AND TUESDAY TIMEFRAME. WE WILL KEEP
MONITORING CLOSELY FOR CHANGES. MSW
AVIATION /06Z TAFS THROUGH 06Z SUNDAY/
ISSUED AT 1010 PM MDT FRI JUL 11 2025
SHOWERS AND STORMS CONTINUE TO MOVE TOWARDS EACH TERMINAL. AN
OUTFLOW BOUNDARY IS FORECAST TO IMPACT KGLD JUST BEFORE THE
START OF THE PERIOD BUT SHOWER AND STORMS ARE ANTICIPATED TO
CONTINUE TO IMPACT THE TERMINAL THROUGH AROUND 09Z WITH PERIODS
OF MVFR CONDITIONS. THE PERHAPS MORE IMPACTFUL TERMINAL IMPACTS
LOOK TO BE FOR KMCK WITH HEAVIER RAINFALL AND THE POTENTIAL FOR
STRONGER WINDS AROUND 45KT. AN INCREASING SIGNAL FOR STRATUS TO
IMPACT KGLD STARTING AROUND 11Z, SOME FOG CAN'T BE RULED OUT BUT
THINK STRATUS IS MOST LIKELY. RAIN SHOULD END LATER AT KMCK THAN
AT KGLD SO NOT IMPACTING ANY IMPACTS. POTENTIAL FOR STRATUS MAY
LINGER AROUND UNTIL THE EARLY AFTERNOON FOR KGLD BEFORE FINALLY
CLEARING OUT.
