DISCUSSION /THROUGH FRIDAY/
ISSUED AT 240 PM MST FRI JAN 9 2026
SOME FLURRIES HAVE LINGERED FOR QUITE A WHILE ACROSS THE SOUTHERN
FOOTHILLS AND PALMER DIVIDE TODAY. THESE WILL COME TO AN END
AROUND SUNSET AS THE DAYTIME HEATING ENDS. CLOUDS WILL CLEAR
TONIGHT WITH DRY CONDITIONS. THIS WILL ALLOW TEMPERATURES TO FALL
BELOW NORMAL WITH TEENS ACROSS MOST OF THE URBAN CORRIDOR AND
PLAINS WITH SINGLE DIGITS ON THE PALMER DIVIDE AND IN THE USUAL
COLD SPOTS LIKE GREELEY AND LIMON.
FROM SATURDAY THROUGH THE FOLLOWING WEEK, COLORADO WILL BE ON THE
EASTERN EDGE OF AN ANOMALOUSLY STRONG RIDGE OVER THE WESTERN US.
THIS WILL LEAD TO AN EXTENDED PERIOD OF DRY WEATHER DUE TO
SUBSIDENT FLOW. TEMPERATURES ALOFT WILL INCREASE THROUGH TUESDAY
WITH TEMPERATURES WARMING ABOVE NORMAL. MONDAY AND TUESDAY WILL
HAVE HIGHS IN THE UPPER 50S TO 60S ACROSS THE I-25 CORRIDOR AND
PLAINS. WINDS WILL BE BREEZY EACH DAY BUT THERE ARE NOT EXPECTED
TO BE ANY SIGNIFICANT HIGH WIND EVENTS. SOME ELEVATED FIRE WEATHER
CONDITIONS MAY DEVELOP ACROSS THE NORTHEAST PLAINS ESPECIALLY ON
TUESDAY.
SHORTWAVE TROUGHS WITHIN THE NORTHWESTERLY FLOW ALOFT MAY MOVE
OVER COLORADO TUESDAY NIGHT AND AGAIN ON THURSDAY INTO FRIDAY. THE
TUESDAY NIGHT TROUGH MAY BRING VERY LIGHT PRECIPITATION TO OUR
FORECAST AREA. THE THURSDAY TROUGH MAY ALSO BRING LIGHT
PRECIPITATION AND COULD ALLOW COLDER TEMPERATURES TO SLIDE ACROSS
THE NORTHEAST PLAINS.

ISSUED AT 1051 AM MST FRI JAN 9 2026
SOME LINGERING LIGHT SNOW AND LOW CLOUDS WILL BE OVER APA AND BJC UNTIL

MAIN IMPACT WILL BE WINDS AT ALL TERMINALS. GUSTY NORTHERLY WINDS

DRAINAGE AROUND 06Z AND WINDS COULD GUST UP TO 24 KNOTS AT DEN OUT
OF THE SOUTHWEST GIVEN THE CURRENT SNOWPACK CONFIGURATION.
FOR THE FORECAST ON SATURDAY, MODELS ARE IN DISAGREEMENT AS TO
WHETHER THE WINDS WILL BE WESTERLY OR NORTHERLY AT ALL TERMINALS.
GIVEN THE NORTHWESTERLY FLOW ALOFT, IT MAY JUST END UP UP BEING
NORTHWEST WINDS BUT SOME UNCERTAINTY STILL EXISTS.
