DISCUSSION /THROUGH WEDNESDAY/
ISSUED AT 1120 PM MDT WED MAY 6 2026
BACK TO OUR REGULARLY SCHEDULED PROGRAMMING. SUB-FREEZING
TEMPERATURES ARE ANYTHING BUT UNIFORM CURRENTLY AND THAT'LL
CONTINUE TO BE THE CASE THROUGH SUNRISE, ESPECIALLY FOR THE I-25
CORRIDOR WHERE FINGERS OF DOWNSLOPE WINDS WILL PERSIST. THE
FREEZE WARNING WILL BE MAINTAINED FOR NOW, AS THE MAJORITY OF THE
PLAINS, AND SOME PATCHY URBAN CORRIDOR LOCATIONS WILL REMAIN BELOW
FREEZING THROUGH THE EARLY MORNING HOURS. LATER TODAY, RISING
HEIGHTS UNDER NORTHWEST FLOW ALOFT WILL ALLOW TEMPERATURES TO
RETURN TO NEAR SEASONAL AVERAGES. DURING THE LATTER HALF OF THE
DAY, A SUBTLE SHORTWAVE WILL ZIP OVER NORTHEAST COLORADO, AND
BRING ISOLATED TO SCATTERED HIGH- BASED SHOWERS LATE AFTERNOON
INTO THE EVENING HOURS FOR THE MOUNTAINS AND THE NORTHERN PLAINS.
MOST OTHER AREAS, INCLUDING THE URBAN CORRIDOR, WILL LARGELY REMAIN
DRY.
THE HIGH COUNTRY WILL WARM FARTHER INTO FRIDAY, WHILE TEMPERATURES
LOOK TO STABILIZE FOR THE LOWER ELEVATIONS. MOISTURE ALOFT WILL BE
LIMITED AND THUS ALL AREAS SHOULD REMAIN DRY.
ANOTHER SHORTWAVE IS SLATED TO TRAVERSE THE REGION SATURDAY,
ALONG WITH A WEAKENING FRONT AND ADVECTION OF HIGHER DEWPOINTS
INTO THE PLAINS IN THE LATE AFTERNOON AND EVENING. THIS WILL BRING
A SHOT AT SCATTERED SHOWERS IN THE LATE AFTERNOON AND EVENING AND
PERHAPS ACCOMPANIED BY A FEW THUNDERSTORMS WITH LINGERING MARGINAL
ML CAPE. MORE NOTABLY, PRE-FRONTAL WINDS WILL BE HEFTY IN THE HIGH
COUNTRY WITH GUSTS 35-50 MPH, AND BREEZY CONDITIONS WILL EXTEND
INTO THE LOWER ELEVATIONS AS WELL WERE GUSTS MAY APPROACH 40 MPH.
OUR AREA WILL DRY BACK OUT BY SUNDAY AS THE WARMING TREND IS
REINFORCED AND TEMPERATURES CLIMB INTO THE 70'S. UPPER-LEVEL
RIDGING WILL INCH CLOSER NEXT WEEK AND KEEP US IN A DRY AND
SUBSIDENT PATTERN, LEADING TO CONSIDERABLY WARMER TEMPERATURES (IN
THE 80'S) DURING THE WEEK. MONDAY LOOKS WARMEST AT THIS TIME, WHEN
HIGHS COULD APPROACH 90F FOR THE WARMEST PLAINS AND I-25 CORRIDOR
LOCATIONS.
AVIATION /18Z TAFS THROUGH 18Z FRIDAY/
ISSUED AT 1147 AM MDT THU MAY 7 2026
WE ARE STARTING TO SEE DRAINAGE WINDS FINALLY TURN TO THE WSW/W
ACROSS THE DENVER TAF SITES LATE THIS MORNING. AS SURFACE HEATING
CONTINUES, WE SHOULD SEE MORE W TO WNW WINDS MIX DOWN WITH GUSTS
BETWEEN 20-25KTS POSSIBLE THROUGH THE AFTERNOON. STILL ANTICIPATE
SOME HIGH-BASED SHOWERS DEVELOPING THIS EVENING, THOUGH CONFIDENCE
IS LOW ON WHETHER THEY WILL PASS DIRECTLY OVER THE TAF SITES, WITH
HIGHER CONFIDENCE IN THEM STAYING NORTH AND NORTHEAST OF THE
AIRFIELDS, THOUGH HAVE HIGH ENOUGH CONFIDENCE TO WARRANT VCSH FOR
KDEN/KAPA THROUGH ROUGHLY 6Z THIS EVENING. WITH THE PASSING
SHOWERS TO THE NORTH, EXPECTING WINDS TO TRANSITION TO A MORE
NORTHERLY COMPONENT FOR A FEW HOURS AFTER 0Z. A FEW HI-RES
SOUNDINGS INDICATE POTENTIAL FOR SOME LOW CLOUDS DEVELOPING EARLY
FRIDAY MORNING (BETWEEN ROUGHLY 12-15Z) THOUGH CONFIDENCE IS NOT
HIGH IN THIS OUTCOME (10-15%), AS DRAINAGE WINDS ARE EXPECTED TO
EVENTUALLY SETTLE IN BEFORE THEN THAT WOULD LIMIT THIS POTENTIAL.
WINDS ARE EXPECTED TO TURN CLOCKWISE FROM DRAINAGE BY THE LATE
MORNING, TURNING TO THE NORTHEAST BY THE AFTERNOON.
BOU WATCHES/WARNINGS/ADVISORIES
NONE.
