IT WAS A PLEASANT DAY ACROSS NORTHEASTERN COLORADO TODAY. SUNSHINE
RETURNED AND THE URBAN CORRIDOR ONLY SAW HIGHS IN THE UPPER 60S
TO NEAR 70. TONIGHT'S TEMPERATURES WILL FEEL LIKE FALL AS LOWS IN
THE 40S ARE EXPECTED IN THE PLAINS WITH MID 20S TO UPPER 30S IN
THE MOUNTAINS AND VALLEYS. THERE IS ALSO THE CHANCE FOR SOME
PATCHY FOG/LOW CLOUDS FRIDAY MORNING MAINLY IN THE EASTERN PLAINS,
CHEYENNE RIDGE, AND PALMER DIVIDE. A WEAK CYCLONE DEVELOPING
OVERNIGHT MAY ALSO SUPPORT A SLIGHT RISK OF FOG NORTH OF DENVER
ALONG THE I-25 CORRIDOR.
THIS WEEKEND A RIDGE IS STILL EXPECTED TO BUILD OVER EASTERN UTAH
AND WESTERN COLORADO BRINGING ABOVE AVERAGE TEMPERATURES. FRIDAY AND
SUNDAY WILL SEE SIMILAR TEMPERATURES WITH UPPER 70S/LOWER 80S ACROSS
THE I-25 CORRIDOR, DENVER METRO, AND EASTERN PLAINS. LINCOLN COUNTY
AND THE PALMER DIVIDE WILL BE SLIGHTLY COOLER IN THE UPPER 60S.
SATURDAY WILL BE A FEW DEGREES WARMER AREA WIDE IN THE LOW/MID 80S
WITH SOME LOCATIONS REACHING THE UPPER 80S. ADDITIONALLY, A WEAK
COLD FRONT APPEARS TO MAKES ITS WAY THROUGH THE NORTHEASTERN PLAINS
SATURDAY AFTERNOON CAUSING BREEZY CONDITIONS WITH GUSTS IN THE 20-30
KTS RANGE. THIS WILL NOT TAME TEMPERATURES AT ALL THOUGH AS MIXING
WILL STILL INDUCE TEMPERATURES IN THE LOW/MID-80S. IT IS ALSO WORTH
IT TO NOTE THAT ELEVATED FIRE WEATHER CONDITIONS ARE EXPECTED FOR A
FEW HOURS SATURDAY AFTERNOON IN THE CHEYENNE RIDGE REGION WITH THE
PASSAGE OF THE FRONT.
MONDAY TEMPERATURES HEAT UP TO NEAR RECORD FOR DENVER. CURRENT
FORECASTED TEMPERATURE IS 86 AND THAT WOULD PUT US JUST ONE DEGREE
SHY FROM THE DAILY RECORD SET IN 2024 AT 87 DEGREES. ELSEWHERE, WE
SHOULD REACH THE MID/UPPER 80S WHILE IT STAYS SLIGHTLY COOLER IN THE
UPPER 70S NEAR LINCOLN COUNTY AND THE PALMER DIVIDE. DETERMINISTIC
MODELS SHOWS A WEAK DISTURBANCE IN THE RIDGE THAT COULD MOVE ACROSS
OUR AREA TUESDAY, AND FORECAST SOUNDINGS DEPICT SOME MOISTURE MOVING
IN ALOFT. THIS SHOULD BE THE GREATEST CHANCE IN THE HIGHER TERRAIN
AS THE DISTURBANCE MOVES OVERHEAD AND MOISTURE FILLS IN. WE
CURRENTLY HAVE A 20-30% FOR AN ISOLATED SHOWER OR WEAK STORM ACROSS
THE HIGH COUNTRY. WITH A FOCUS ON THE CENTRAL MOUNTAINS, SUCH AS
CLEAR CREEK AND SUMMIT COUNTIES. THROUGH THE END OF NEXT WEEK THE
DRY STAGNANT PATTERN LOOKS TO RETURN AS THE RIDGE DEVELOPS OVERHEAD
ONCE AGAIN. ABOVE NORMAL TEMPERATURES ARE EXPECTED TO CONTINUE IN
THE UPPER 70S AND LOWER 80S.
AVIATION /12Z TAFS THROUGH 12Z SATURDAY/
ISSUED AT 539 AM MDT FRI OCT 2 2026
CURRENT OBSERVATIONS SHOW SOUTHERLY WINDS IN PLACE AT KDEN/KAPA,
WITH LIGHT AND MOSTLY VARIABLE WINDS REMAINING AT KBJC. SATELLITE
IMAGERY SHOWS FOG IN PLACE ALONG THE PALMER DIVIDE AND CHEYENNE
RIDGE, WITH THE SOUTHERLY WINDS/COMPRESSIONAL WARMING OFF THE
PALMER KEEPING THE FOG FROM PROGRESSING NORTHWARD INTO KAPA. WHILE
FOG IS STILL NOT EXPECTED TO DIRECTLY IMPACT THE AIRFIELDS, A FEW
OBSERVATIONS OVER THE NORTHERN URBAN CORRIDOR HAVE TWO TO THREE
DEGREE DEWPOINT DEPRESSIONS, WHICH COULD STILL PRODUCE ADDITIONAL
FOG DEVELOPMENT WITH ANY SLIGHT COOLING OR INCREASE TO RH IN THE
NEXT HOUR OR TWO. WITH NORTHERLY WINDS IN PLACE ALONG THE NORTHERN
I-25 CORRIDOR, IF FOG (OR EVEN SOME LOW CLOUDS) WERE TO FORM, THIS
COULD STILL GET ADVECTED SOUTHWARD TOWARDS KBJC/KDEN AND DISRUPT
VISIBILITY FOR PLANES LANDING FROM THE SOUTH. THEREFORE, HAVE KEPT
THE VCFG FROM 13Z-15Z AS THIS SCENARIO CANNOT BE COMPLETELY RULED
OUT DESPITE CONFIDENCE REMAINING LOW AT THIS TIME.
EXPECTING WINDS TO BECOME SLIGHTLY MORE SOUTH-SOUTHWESTERLY AND
DECREASE IN MAGNITUDE FOR A FEW HOURS EARLY THIS MORNING BEFORE
TURNING BACK TO THE SOUTH TO SOUTHEAST FOR THE AFTERNOON. THE
LATEST GUIDANCE HAS STARTED TO TREND SLIGHTLY MORE EAST-SOUTHEASTERLY
IN THE PAST FEW RUNS, BUT SPEEDS SHOULD REMAIN LIGHTER WITH THIS
SCENARIO (GENERALLY BELOW 7KTS) COMPARED TO THE SLIGHTLY HIGHER
SPEEDS WITH A MORE SOUTHEASTERLY WINDS PORTRAYED IN THE TAF. ANOTHER
ROUND OF ENHANCED SOUTHERLY WINDS IS EXPECTED THROUGH THE
EVENING, BEFORE SETTLING INTO DRAINAGE WINDS FOR THE OVERNIGHT
HOURS.
BOU WATCHES/WARNINGS/ADVISORIES
NONE.
