DISCUSSION
ISSUED AT 1042 PM MDT MON JUN 8 2026
NEW FIRE STARTS AND A DANGEROUS FIRE WEATHER PATTERN SETTING UP
FOR TUESDAY INTO WEDNESDAY ARE THE FORECAST HIGHLIGHTS FOR THIS
PACKAGE. A CLIMATOLOGICAL FAVORED PATTERN FOR EXTREME FIRE
CONDITIONS HAS SET UP WITH A LARGE WESTERN TROUGH DIGGING INTO
AN UPSTREAM RIDGE. OUR CWA IS IN THE INTERFACE OF THESE FEATURES
WHICH IS WHERE SOME OF THE STRONGEST WINDS WILL RESIDE. DROUGHT
CONDITIONS HAVE CREATED A VERY DRY BOUNDARY LAYER WHICH WILL
ADD AN ELEMENT OF HEIGHTENED CONCERN TO THE WIDESPREAD RED FLAG
CONDITIONS THAT WILL BE IN PLACE AGAIN TOMORROW. GOES ALPW SHOW
A BATCH OF ELEVATED MOISTURE TO OUR SOUTH THAT WILL ADVECT
THROUGH SOUTHWEST COLORADO EARLY THIS MORNING. THIS MOISTURE
OVER-RUNNING THE DRY LOW LAYERS UNFORTUNATELY MEANS MINIMAL
MOISTURE WILL BE MAKING TO THE GROUND...WITH WIND AND LIGHTNING
THE MORE LIKELY THREATS. PROBABLY DON'T NEED TO SAY ANY NEW FIRE
STARTS AHEAD OF STRONG WINDS AND LOW HUMIDITY ARRIVING LATER IN
THE MORNING/EARLY AFTERNOON IS NOT OPTIMAL. GRADIENT WINDS WILL
BE STRONG ENOUGH OVER MANY OF OUR VALLEY LOCATIONS THAT
ADVISORIES ARE IN PLACE AS WINDS COULD GUST UP TO 50 MPH DURING
THE PEAK HEATING HOURS. THE MAIN TROUGH AXIS WILL BEGIN TO SWING
THROUGH TOMORROW EVENING ALONG WITH A CYCLONICALLY CURVED JET
PROVIDING LARGE SCALE ASCENT OVER OUR NORTHERN ZONES. MOISTURE
MOVING IN WITH THE TROUGH AND LOWER LEVEL FORCING FROM A COOL
FRONT MOVES THE THREAT OF LIGHTNING AND GUSTY WINDS TO OUR
NORTHERN ZONES THROUGH EARLY WEDNESDAY MORNING. THIS OF COURSE
IS FOLLOWED BY ANOTHER ROUND OF STRONG WINDS APPROACHING
ADVISORY LEVELS ACROSS THE NORTHERN VALLEYS WEDNESDAY AFTERNOON.
WIDESPREAD RED FLAG WARNINGS CONTINUE AS A RESULT. ANY
LINGERING MOISTURE WILL BE WIPED OUT BEHIND THE TROUGH AND IF
THERE IS ANY GOOD NEWS THE THREAT OF LIGHTNING WILL BE
ELIMINATED AS WE HEAD INTO THE LATE WEEK PERIOD.
WINDS DIMINISH ON THURSDAY, BUT FIRE WATCHES HAVE BEEN ISSUED
FOR SOME AREAS WEST OF THE DIVIDE. THIS TREND LIKELY CONTINUES
INTO THE WEEKEND, AS TEMPERATURES SURGE IN EXCESS OF 10 DEGREES
OVER NORMAL AGAIN. THIS HOT AND DRY PATTERN WILL PRODUCE AREAS
OF CRITICAL FIRE WEATHER AGAIN. MODELS ARE HINTING AT SOME
RETURN MOISTURE WORKING NORTHWARD BENEATH THE HIGH FRIDAY AND
BEYOND. WHETHER THIS YIELDS ANY SHOWER ACTIVITY OVER THE
WEEKEND, REMAINS A LOW CONFIDENCE FORECAST. IT IS LOOKING LIKELY
THAT WE REMAIN HOT AND DRY FOR MUCH OF THE REGION, HOPING FOR A
FEW CLOUDS AND A SHOWER TO CHIP AWAY AT THE HEAT A BIT.
AVIATION /00Z TAFS THROUGH 00Z WEDNESDAY/
ISSUED AT 525 PM MDT MON JUN 8 2026
WIND WILL BE THE BIG STORY IN THE TAF FORECASTS OVER THE NEXT 24
HOURS. A STRONG JET ALOFT WILL LEAD TO AREAS OF LLWS AS THE
LOWER LAYERS REMAIN CUTOFF DURING THE OVERNIGHT AND MORNING
HOURS. AS HEATING KICKS IN THIS WIND WILL MIX DOWN WITH
WIDESPREAD GUSTS OF 35 TO 50 MPH ACROSS THE BOARD BY EARLY
AFTERNOON. A BATCH OF MOSITURE IN THIS FLOW WILL ALSO LEAD TO
SOME LOWER PROBABILITY OF SHOWERS/VIRGA OVER KDRO TOMORROW
MORNING. VFR IS EXPECTED OVER THE NEXT 24 HOURS...HOWEVER SMOKE
FROM NEW FIRES AND BLOWING DUST MAY LEAD TO LOWER VISIBILITY BUT
CONFIDENCE NOT HIGH ENOUGH TO PUT IN THE FORECAST ATTM.
FIRE WEATHER
ISSUED AT 1042 PM MDT MON JUN 8 2026
CRITICAL FIRE WEATHER PERSISTS THROUGH AT LEAST THURSDAY AND IS
LIKELY TO CONTINUE INTO THE WEEKEND AS TEMPERATURES SURGE 10
DEGREES OVER NORMAL. WINDS INCREASE TOMORROW WITH GUSTS UP TO 50
MPH POSSIBLE IN MANY VALLEY LOCATIONS WHERE HUMIDITY WILL BE
NEAR THE SINGLE DIGITS. FIRE ZONES WITH CRITICAL FUELS HAVE BEEN
PLACED UNDER RED FLAG WARNINGS THROUGH WEDNESDAY. FIRE WEATHER
WATCHES ON THURSDAY HAVE A HIGH PROBABILITY OF BEING UPGRADED IN
LATER FORECASTS.
ISOLATED SHOWERS AND THUNDERSTORMS ARE POSSIBLE AT TIMES FOR
THE NEXT SEVERAL DAYS, WHICH INCREASES THE POTENTIAL FOR NEW
FIRE STARTS. WINDS DIMINISH THURSDAY, BUT REMAIN GUSTY AGAINST
THE DIVIDE, PROMPTING ANOTHER FIRE WEATHER WATCH THURSDAY
AFTERNOON. THIS HOT, DRY, WINDY PATTERN SHOWS NO SIGNS OF
ABATING THIS WEEKEND WITH THE RETURN OF WARMER TEMPERATURES.
