KEY MESSAGES
- RED FLAG WARNING IN EFFECT FOR EASTERN COLORADO THIS
AFTERNOON, WHERE HUMIDITY IN THE LOW TEENS AND WIND GUSTS UP
TO ~35 MPH ARE EXPECTED.
- A FEW NORTHERLY WIND GUSTS ~45 TO 55 MPH POSSIBLE DURING A
COLD FRONTAL PASSAGE THIS EVENING, MAINLY IN EASTERN CO.
- CONDITIONAL POTENTIAL FOR A BRIEF SEVERE STORM IN FAR EASTERN
PORTIONS OF THE AREA ON SATURDAY, MAINLY IN NORTON, GRAHAM
AND GOVE COUNTIES.
- A GREATER PORTION OF THE AREA WILL SEE A CONDITIONAL
POTENTIAL FOR SEVERE THUNDERSTORMS ON SUNDAY. LARGE HAIL AND
DAMAGING WINDS WOULD BE THE PRIMARY HAZARDS, SHOULD SEVERE
STORMS DEVELOP.
SHORT TERM /THROUGH SUNDAY NIGHT/
ISSUED AT 1220 AM MDT FRI APR 24 2026
HIGH PRESSURE IS PUSHING IN FROM THE WEST AND IS FORECAST TO
LEAD TO LIGHT WINDS ACROSS THE AREA OVERNIGHT. WITH DEW POINTS
IN PLACE WOULD NOT BE SURPRISED IF SOME FREEZING TEMPERATURES
COULD OCCUR ACROSS EASTERN COLORADO, ESPECIALLY ACROSS THE
HIGHEST ELEVATIONS. FRIDAY, THE SURFACE HIGH IS FORECAST TO MOVE
TO THE EAST ACROSS THE AREA. ACROSS COLORADO A SURFACE LOW IS
FORECAST TO DEVELOP AND TURN WINDS TO THE SOUTHWEST ACROSS THE
YUMA, KIT CARSON AND CHEYENNE (CO). THIS IS WHERE THE MOST
LIKELY AREA TO SEE SEVERAL HOURS OF CRITICAL FIRE WEATHER LIES.
WITH MIXING HEIGHTS OF 10,000-13,000 FEET AGL THERE SHOULD BE NO
ISSUE IN WINDS MIXING DOWN AND OVERLAPPING A RED FLAG WARNING
HAS BEEN ISSUED FOR THOSE 3 COUNTIES AS HUMIDITY IS FORECAST TO
FALL INTO THE LOW TEENS AND WIND GUSTS UP TO 30 MPH ARE FORECAST
TO OCCUR. AN HOUR OR TWO OF CRITICAL CONDITIONS IS FORECAST TO
OCCUR FROM DUNDY DOWN THROUGH WALLACE COUNTY AS THE LOW DEEPENS
A TIGHTER PRESSURE GRADIENT DEVELOPS AFTER 21Z. I OPTED TO NOT
ISSUE FOR THESE COUNTIES DUE TO CONFIDENCE BEING AROUND 60% IN 3
OR MORE HOURS OCCURRING. IF THE LOW CAN SET UP A LITTLE FURTHER
EAST AND WINDS BECOME MORE SOUTHWESTERLY SOONER THEN A SHORT
LEAD TIME WARNING MAY BE NEEDED AS DRY AIR WOULD INTRUDE
QUICKER. DURING THE LATE AFTERNOON SOME WEAK 500MB VORTICITY
MAXIMA ARE FORECAST TO MOVE THROUGH THE AREA ASSOCIATED WITH
WEAK SHORTWAVES. VIRGA IS POSSIBLE BUT WITH A DEEP LAYER OF DRY
AIR NO PRECIPITATION IS FORECAST TO MAKE IT TO THE SURFACE. 00Z
FORECAST SOUNDINGS INDICATE A FEW HUNDRED JOULES AND STEEP LAPSE
RATES INDICATING THAT SOME DRY LIGHTNING STRIKES CAN'T BE RULED
OUT.
A COLD FRONT IS FORECAST TO MOVE THROUGH DURING THE MID TO LATE
EVENING AND SHIFT WINDS TO THE NORTH. WIND GUSTS OF 40-55 MPH
ARE MOST LIKELY WITH MIXING HEIGHTS AROUND 1000 FEET AGL VIA
ALONG WITH SUSTAINED WINDS OF 25-35 MPH BUT THERE IS A 20%
CHANCE OF ISOLATED WIND GUSTS AROUND 60 MPH AS WELL. IF VIRGA IS
IN PLACE THEN THE CONCERN FOR 60+ MPH WIND GUSTS MIXING DOWN
WITH THE FRONT WITH INCREASE AS WELL. THIS WOULD ALSO RAISE THE
CONCERN FOR BLOWING DUST AND LOCALIZED DUST STORMS SIMILAR TO
WHAT OCCURRED ON THURSDAY; ALTHOUGH THE IMPACTS WOULD BE LESSER
DUE TO THE TIME OF THE DAY.
INTO THE DAY SATURDAY, BEHIND THE FRONT STRONG SIGNAL FOR
STRATUS IS SEEN FOR THE MORNING HOURS AND INCREASING LOW LEVEL
OMEGA WHICH MAY LEAD TO SOME LIGHT RAIN SHOWERS ACROSS THE AREA
DURING THE MORNING AND INTO THE EARLY AFTERNOON HOURS. CURRENTLY
THE FAVORED AREA FOR LIGHT RAIN IS ACROSS THE NORTH AND EASTERN
PORTIONS OF THE AREA. A CHILLIER DAY IS FORECAST FOR SATURDAY
WITH HIGHS IN THE UPPER 50S TO THE UPPER 60S ACROSS THE SOUTH.
IF CLOUD COVER IS THICK ENOUGH THEN HIGH TEMPERATURES MAY STILL
BE 5-10 DEGREES TO WARM. MOISTURE RETURN IS THEN FORECAST TO
OCCUR SATURDAY EVENING AND AGAIN INCREASE RAINFALL CHANCES AS
WINDS TURN MORE EASTERLY DUE TO THE POSITIONING OF A SURFACE
LOW. THE BETTER POTENTIAL FOR RAINFALL LOOKS TO OCCUR DURING THE
EVENING AND OVERNIGHT HOURS. THERE IS SMALL AND CONDITIONAL
CHANCE FOR A SEVERE STORM OR TWO MAINLY ALONG AND EAST OF A
DECATUR TO GOVE COUNTY LINE AS SYNOPTIC FORCING INCREASES AHEAD
OF A LARGER SCALE TROUGH. A LOT OF MESOSCALE FACTORS SUCH AS DRY
LINE LOCATION AND IF EARLIER DAY RAINFALL AND STRATUS POTENTIAL
CAN INTERFERE WITH THE ENVIRONMENT. SHOULD A STORM DEVELOP
LARGE HAIL AND DAMAGING WINDS WOULD BE THE MAIN CONCERNS WITH
MIXED LAYER CAPE RANGING FROM 900-1600 J/KG DEPENDENT ON THE
QUALITY OF MOISTURE PRESENT, STEEP LAPSE RATES AND SURFACE-6KM
SHEAR AROUND 35- 45 KNOTS WHICH WOULD BE SUPPORTIVE FOR SEVERE
WEATHER. STRAIGHT LINE HODOGRAPHS ARE ALSO SEEN AS WELL WHICH
WOULD SUPPORT SPLITTING OF CELLS. AM NOTICING A CAP AROUND 700MB
WHICH WOULD LIMIT COVERAGE AND IF STORMS EVEN OCCUR AT ALL.
CONFIDENCE IN STORMS FORMING IS AROUND 10% AND SEVERE WEATHER IS
LESS THAN 5% CURRENTLY. ECMWF DOES INDICATE A WEAK SHORTWAVE IN
THE AREA WHICH WOULD SERVE AS LIFT BUT IS CURRENTLY THE OUTLIER
AT THIS TIME.
LONG TERM /MONDAY THROUGH FRIDAY/
ISSUED AT 219 PM MDT FRI APR 24 2026
STARTING OFF THE WORK WEEK, A SURFACE LOW IS FORECAST TO SET UP IN
EASTERN KANSAS AND THERE IS A CLOSED LOW DEVELOPING OFF THE COAST OF
CALIFORNIA. OUR REGION IS IN A MOSTLY SOUTHWEST UPPER-LEVEL FLOW.
HIGH TEMPERATURES ARE FORECAST IN THE 60S WITH LOWS IN THE 30S. AS
THE DAY PROGRESSES, SEVERAL EMBEDDED SHORTWAVES PASS THROUGH THE
REGION BRINGING AFTERNOON CHANCES FOR PRECIPITATION. PROBABILITY OF
PRECIPITATION (POPS) ARE AROUND 30-40% FOR THE WESTERN AND NORTHERN
PORTIONS OF THE COUNTY WARNING AREA (CWA). RAIN SHOWERS ARE MOST
LIKELY, BUT SOME WEAK INSTABILITY COULD INITIATE A COUPLE
THUNDERSTORMS. WHETHER STORMS FORM OR NOT, WINDS WILL BE A CONCERN
MONDAY AS A JET STREAK SETS UP OVER OUR CWA. WINDS ARE FORECAST FROM
THE NORTH/NORTHWEST WITH GUSTS OF 25-40 MPH POSSIBLE NORTH OF THE I-
70 CORRIDOR.
TUESDAY, SOUTHWEST FLOW ALOFT REMAINS IN PLACE OVER THE REGION WITH
A JET STREAK OVERHEAD. THE FORECAST REMAINS FAIRLY CONSISTENT FROM
YESTERDAY. WIND GUSTS ARE FORECAST AROUND 30 MPH FOR THE NORTHWEST
CWA AND RELATIVE HUMIDITY VALUES (RH) ARE FORECAST IN THE 20S. THE
STRONGEST WIND GUSTS DO NOT ALIGN WITH THE LOWEST RH VALUES, SO FIRE
WEATHER CONCERNS ARE MINIMAL FOR TUESDAY.
PRECIPITATION CHANCES REMAIN FOR THE NORTHWEST CWA TUESDAY AFTERNOON
WITH POPS RANGING FROM 30-50% DUE TO PASSING SHORTWAVES AND JET
SUPPORT ALOFT. LOW CONFIDENCE ON SPECIFIC HAZARDS AT THIS TIME, BUT
SPORADIC, WEAK CAPE PRESENT IN THE ECMWF AND GFS FOR EASTERN
COLORADO. IF A THUNDERSTORM IS ABLE TO FORM, HAIL COULD BE POSSIBLE.
WEDNESDAY ON, WE HAVE POTENTIAL FOR A MORE ACTIVE PATTERN. EXPECT
AFTERNOON AND EVENING CHANCES FOR SHOWERS AND THUNDERSTORMS AS THE
CWA REMAINS UNDER SOUTHWEST FLOW ALOFT WITH JET SUPPORT AND PASSING
SHORTWAVES.
