LOCALIZED SLICK SPOTS DUE TO FREEZING FOG CAN'T BE RULED OUT.
- RAIN SHOWERS ARE FAVORED ALONG AND NORTH OF INTERSTATE 70
TUESDAY.
- THURSDAY COULD SEE SOME FIRE WEATHER THREAT ALONG WITH THE
POTENTIAL FOR THUNDERSTORMS FOR PORTIONS OF THE AREA DURING
THE EVENING AND OVERNIGHT.
SHORT TERM /THROUGH THURSDAY NIGHT/
ISSUED AT 1231 PM MST MON MAR 2 2026
FOG AND STRATUS IS TAKING ITS SWEET TIME LEAVING GRAHAM AND NORTON
COUNTIES THIS MORNING BUT IS FORECAST TO DO SO A LITTLE AFTER 18Z AS
A DEVELOPING TIGHT PRESSURE GRADIENT ASSOCIATED WITH A SURFACE
LOW ACROSS COLORADO MOVES TOWARDS THE AREA. AS THE PRESSURE
GRADIENT TIGHTENS BREEZY WINDS ARE FORECAST TO DEVELOP ACROSS
THE AREA WITH WIND GUSTS AROUND 30 MPH FORECAST. A WIDE RANGE OF
HIGH TEMPERATURES REMAINS FORECAST ACROSS THE AREA FOR THE DAY
DUE TO THE LINGERING FOG AND STRATUS AND THE LOW ACROSS COLORADO
WITH HIGHS IN THE MID TO UPPER 40S ACROSS GRAHAM AND NORTON AND
TO THE UPPER 60S TO LOW 70S ACROSS EASTERN COLORADO.
TONIGHT AS THE LOW MOVES TOWARDS THE AREA, MOISTURE WILL BEGIN TO BE
ADVECTED INTO THE AREA LEADING TO FOG AND STRATUS ACROSS THE AREA.
FOG IS FORECAST TO MOVE INTO NORTON AND GRAHAM COUNTIES AS EARLY AS
11PM CT TONIGHT AND GRADUALLY EXPAND TO THE WEST INTO EASTERN
COLORADO. 12Z HREF AND REFS HAVE HIGH TO VERY PROBABILITIES FOR 1/2
MILE OR LESS VISIBILITIES WITH THE HREF AROUND 50-60% AND THE REFS
AROUND 80%. FOR WHAT IT IS WORTH THE REFS WAS LESS EXCITED ABOUT
DENSE FOG POTENTIAL FOR MONDAY MORNING SO SEEING PROBABILITIES THIS
HIGH IS FOR SURE EYE CATCHING. SOME FAIL POINTS TO THE DENSE FOG
POTENTIAL IS THE POTENTIAL FOR SOME DRIZZLE OR LIGHT RAIN TO DEVELOP
STARTING AROUND 09Z OR SO AS CROSS SECTION ANALYSIS SHOWS AROUND -4
MICROBARS OF OMEGA IN THE 925-850 MB LAYER FAVORING EASTERN PORTIONS
OF THE FORECAST AREA. ANOTHER FAIL POINT IS THE POTENTIAL FOR
LINGERING MOUNTAIN CIRRUS TO INTERFERE WITH RADIATIONAL COOLING
POTENTIAL; THIS ONE SEEMS LESS LIKELY AS THE MAJORITY OF THE
FOG LOOKS TO BE ADVECTION BUT IT COULD HAVE AN IMPACT ON THE
COVERAGE AND DURATION. AS WE ARE AWARE FOG FORECASTING IS VERY
FINICKY SO EVEN WITH SUCH HIGH PROBABILITIES WITH THE FEW FAIL
POINTS AM OPTING TO HOLD OFF ON ISSUING A DENSE FOG ADVISORY
THIS SHIFT BUT ONE MAY BE NEEDED IN UPCOMING SHIFTS. AS WHAT WAS
MENTIONED IN THE PREVIOUS DISCUSSION THE THREAT FOR FREEZING
FOG IS A BIT LOWER THAN LAST NIGHT BUT HAVE NOTICED A COOLING
TREND WITH GUIDANCE. I DON'T WANT TO COMPLETELY RULE OUT
FREEZING FOG WITH LOW TEMPERATURES NEAR OR WITHIN A DEGREE OR
TWO OF FREEZING BUT CONFIDENCE IS A BIT LOWER AT THIS TIME.
TUESDAY, AS THE LOW PRESSURE SYSTEM CONTINUES TO MOVE EAST A
COLD FRONT IS FORECAST TO MOVE NORTHWEST TO SOUTHWEST THROUGH
THE AREA ENDING AND FOG AS IT MOVES THROUGH. IF THE FRONT IS A
BIT SLOWER THEN DENSE FOG POTENTIAL FOR EASTERN COUNTIES MAY
LINGER INTO THE EARLY AFTERNOON. THERE IS RAIN POTENTIAL WITH
THE FRONT AS WELL, BUT HAS TRENDED A BIT LESS WIDESPREAD THAN
WHAT WAS BEING SEEN YESTERDAY AND FAVORING THOSE NORTH OF THE
INTERSTATE. THIS APPEARS TO BE TIED TO THE BETTER MID LEVEL
FORCING REMAINING FURTHER TO THE NORTH. RAIN IS THE CURRENT
FORECASTED PRECIPITATION TYPE BUT WOULD NOT BE OVERLY SURPRISED
IF SOME SNOW COULD MIX IN OVER THE HIGHER ELEVATIONS OF YUMA
AND KIT CARSON COUNTIES. NOT EXPECTING ANY IMPACTS IF THIS WERE
TO OCCUR GIVEN THE WARM GROUND TEMPERATURES. HIGH TEMPERATURES
FOR DAY ARE CURRENTLY FORECAST IN THE 50S BUT COULD BE LOWER IF
CLOUDS/FOG WERE TO LINGER LONGER OR IF THE COLD FRONT MOVES
THROUGH QUICKER. TUESDAY NIGHT, FOG COULD AGAIN BE A CONCERN AS
A SURFACE HIGH MOVES IN WAKE OF THE DAY TIME FRONT AS WINDS
BECOME LIGHT AND VARIABLE; GUIDANCE DOES SHOW SOME LINGERING
MOISTURE ACROSS THE AREA AS WELL SO WILL BE SOMETHING TO KEEP AN
EYE ON. RAIN CHANCES ARE FORECAST TO CONTINUE ACROSS THE AREA
AS A SHORTWAVE OFF OF THE ROCKIES MOVES ACROSS THE AREA TUESDAY
NIGHT.
WEDNESDAY CONTINUES TO BE BE THE MOST UNEVENTFUL DAY OF THE WEEK AS
THE REGION IN BETWEEN SYSTEMS AS HIGHS IN THE 60S ARE FORECAST TO
RETURN. LINGERING CLOUDS COULD PERHAPS KNOCK A FEW DEGREES OFF OF
THE CURRENT FORECASTED HIGH TEMPERATURES BUT CONFIDENCE IS NOT
THERE TO MAKE ANY CHANGES AT THIS TIME.
THURSDAY, HAS THE POTENTIAL TO BE THE MORE IMPACTFUL DAY OF THIS
PERIOD. LARGE TROUGHING DEVELOPS OVER THE WESTERN CONUS DURING THE
MORNING HOURS AS A SURFACE OW DEVELOPS ACROSS EASTERN COLORADO
DURING THE AFTERNOON AND THE EVENING HOURS. MOISTURE RETURN IS ALSO
FORECAST TO OCCUR DURING THE DAY AS WELL WHICH IS FORECAST TO LEAD
TO A DRYLINE ACROSS THE AREA. THE TRENDS WITH THE DRYLINE HAS BEEN
TO THE WEST WHICH WAS SEEN IN THE ECMWF YESTERDAY AND NOW THE GFS
AND ITS OVER MIXING BIAS MENTIONED YESTERDAY IS SHOWING THIS
SAME TREND AS WELL. THIS DOES RAISE THE CONCERN FOR SOME STRONG
TO PERHAPS EVEN SEVERE STORMS THURSDAY. THE TIMING IS STILL
BEING WORKED OUT BUT CURRENT FORECAST FAVORS THE EVENING AND
OVERNIGHT AS BETTER SYNOPTIC FORCING MOVES INTO THE AREA. GEFS
MEAN SPREAD AND ECMWF ENSEMBLES DO SHOW THE POTENTIAL FOR A
SLOWER PROGRESSION OF THE SYSTEM WHICH COULD LEAD TO
PRECIPITATION CHANCES STARTING THURSDAY AFTERNOON; THIS IS ALSO
WHEN SOME 700MB JET STREAK DIVERGENCE IS SEEN IN THE ECMWF AS
WELL WHICH WOULD ADD SOME ADDITIONAL FORCING AS WELL. THIS
SLOWER TREND IF IT WERE TO OCCUR WOULD INCREASE THE COVERAGE OF
STRONG TO SEVERE STORM POTENTIAL VERSUS THE CURRENT FORECAST
WHICH WOULD MAINLY FAVOR WICHITA, GOVE, GRAHAM AT THE LEAST.
WILL WAIT AT LEAST ONE MORE FORECAST PACKAGE BEFORE ADDING IN
THUNDER INTO THE FORECAST TO ENSURE THIS TREND CONTINUES.
BEHIND THE DRYLINE THURSDAY, CRITICAL FIRE WEATHER COULD BE A
CONCERN AS WELL AS THE 850 AND 700MB WIND FIELDS BOTH INCREASE WITH
THE INCOMING TROUGH. SUSTAINED WINDS OF 15-25 MPH AND GUSTS TO
40 MPH CURRENTLY APPEAR TO BE THE MOST LIKELY OUTCOME. STILL
WHERE DOES THE DRYLINE SET UP AT? WITH THE WESTERN TREND EASTERN
COLORADO COUNTIES WOULD BE THE MOST LIKELY TO SEE CRITICAL FIRE
WEATHER CONCERNS BUT COULD IMPACT DUNDY DOWN THROUGH GREELEY
COUNTIES AS WELL.
LONG TERM /FRIDAY THROUGH MONDAY/
ISSUED AT 1240 PM MST MON MAR 2 2026
A DEEP UPPER-LEVEL TROUGH LOOKS TO BE IN PLACE ACROSS THE WESTERN
UNITED STATES FRIDAY MORNING, WITH SOUTHWESTERLY FLOW OVERHEAD. A
500-MB SHORTWAVE SYSTEM AND JET STREAK MAY BE EMBEDDED IN THIS FLOW,
WHICH COULD ESTABLISH A SURFACE LOW PRESSURE ACROSS THE TRI-STATE
AREA. SEVERAL DIFFERENT SCENARIOS ARE POSSIBLE FOR THE WEATHER
CONDITIONS WE MAY EXPERIENCE FRIDAY AFTERNOON, AND VARY BETWEEN
THUNDERSTORMS (POSSIBLY SEVERE), CRITICAL FIRE WEATHER, AND COOLER
CONDITIONS DUE TO A COLD FRONT PASSAGE. THE TYPE OF WEATHER
EXPERIENCED ON FRIDAY WILL HIGHLY DEPEND ON THE EXACT LOCATION OF
THE SURFACE LOW PRESSURE, WHICH IS QUITE UNCERTAIN AT THIS TIME. A
STRONG NORTH-TO-SOUTH ORIENTED DRYLINE LOOKS TO BE ATTACHED TO THIS
SYSTEM, WITH SOUTHERLY SURFACE WINDS AHEAD OF THE DRYLINE, AND
SOUTHWESTERLY BEHIND. SEVERE THUNDERSTORMS WOULD BE MOST LIKELY IF
THE SURFACE LOW CAN TRACK ACROSS NORTHEAST COLORADO AND SOUTHWEST
NEBRASKA DURING THE AFTERNOON HOURS. IN THIS CASE, CONVECTION COULD
INITIATE ALONG THE DRYLINE WHILE IT IS CENTERED IN THE FORECAST
REGION. A SIMILAR TRACK OF THE LOW COULD ALSO PRODUCE CRITICAL FIRE
WEATHER CONDITIONS, BUT WOULD NEED TO HAVE A FASTER PROGRESSION
EASTWARD THAN THE SEVERE CASE. THIS WOULD ALLOW SOUTHWESTERLY 15-20
KNOT WINDS BEHIND THE DRYLINE TO CREATE DRIER CONDITIONS, ESPECIALLY
FOR EASTERN COLORADO AND WEST-CENTRAL KANSAS. RELATIVE HUMIDITIES IN
THE MID-TEENS WOULD BE POSSIBLE, IN ADDITION TO WIND GUSTS UP TO 35
MPH, WHICH WOULD SUPPORT CRITICAL FIRE WEATHER. ALTERNATIVELY, FOR A
SCENARIO OF COOLER CONDITIONS, THE SURFACE LOW COULD TRACK FURTHER
SOUTH, OR PROGRESS EASTWARD MUCH QUICKER TO WHERE IT IS EAST OF THE
CWA BY FRIDAY AFTERNOON. THIS WOULD ALLOW THE COLD FRONT TO PASS
BEFORE OR DURING THE AFTERNOON HOURS. AT THIS TIME, THERE IS NOT A
CLEAR FAVORED SOLUTION.
SURFACE WINDS LOOK TO HAVE A MORE NORTHERLY COMPONENT BY MID TO LATE-
FRIDAY EVENING, WHICH WOULD BRING COOLER CONDITIONS INTO THE CWA.
LOW TEMPERATURES FRIDAY NIGHT ARE CURRENTLY FORECAST IN THE MID-20S
TO LOW-30S. IN ADDITION, PRECIPITATION MAY OCCUR FRIDAY EVENING AND
OVERNIGHT BEHIND THE COLD FRONT. PRECIPITATION TYPE IS UNCERTAIN AT
THIS TIME IN LARGE PART BECAUSE EXACT TIMING IS UNCERTAIN.
PRECIPITATION THAT FALLS EARLIER IN THE NIGHT MAY BE RAIN DUE TO
ABOVE FREEZING TEMPERATURES, THOUGH MAY TRANSITION INTO SNOW OR A
WINTRY MIX WHEN SURFACE TEMPERATURES DROP BELOW FREEZING. PORTIONS
OF EASTERN COLORADO SEEM TO BE MOST FAVORED TO RECEIVE THIS ROUND OF
PRECIPITATION.
THE REMAINDER OF THE FORECAST PERIOD LOOKS TO BE CHARACTERIZED BY A
SECLUDED 500-MB LOW IN THE SOUTHWEST UNITED STATES, AND A HIGHLY
DISTURBED JET STREAM ACROSS THE NORTHERN UNITED STATES AND SOUTHERN
CANADA. RIDGING DOWNSTREAM OF THE SECLUDED LOW AND SHORTWAVE TROUGHS
EMBEDDED IN THE JET STREAM FLOW TO THE NORTH LOOK TO BATTLE FOR
DOMINANCE, INTRODUCING ADDITIONAL UNCERTAINTY INTO THE FORECAST.
TEMPERATURES MAY FLUCTUATE HIGHER OR LOWER AS A CONSEQUENCE OF THIS
PATTERN, THOUGH TIMING OF THESE FLUCTUATIONS REMAIN AMBIGUOUS. EVEN
SO, NBM GUIDANCE SUGGESTS DRY, PRECIPITATION-FREE CONDITIONS
THROUGH MONDAY AFTERNOON.
