SHORT TERM /THROUGH FRIDAY NIGHT/
ISSUED AT 110 PM MDT THU APR 30 2026
REST OF TODAY AND TONIGHT..
SCATTERED SHOWERS REMAIN DRAPED ACROSS MUCH OF THE FORECAST
AREA. LIGHTNING IS NOT PRESENT YET, BUT THERE IS ENOUGH
CLEARING OVER FREMONT COUNTY AND THE NORTHERN SANGRES THAT WE
MAY BEGIN TO SEE LIGHTNING ACTIVITY AND HEAVIER PRECIPITATION
RATES WITHIN THE NEXT HOUR OR TWO. TEMPERATURES ARE MOSTLY IN
THE 40S ON THE PLAINS, WITH SPRINGFIELD AND ALAMOSA BOTH SITTING
AT 54F AS OF NOON, AND FAR NORTHEASTERN PORTIONS OF EL PASO
COUNTY SITTING IN THE UPPER 30S. THIS LULL IN PRECIPITATION
LOOKS TO PERSIST FOR ANOTHER COUPLE OF HOURS, BEFORE ENOUGH
CLEARING AND INSTABILITY PUSH OFF THE MOUNTAINS TO INITIATE OUR
STRONGER CONVECTION IN PLACES LATER THIS AFTERNOON AS BETTER
FORCING ARRIVES. THIS WILL INCREASE COVERAGE AND INTENSITY OF
PRECIPITATION ACROSS THE AREA THIS AFTERNOON THROUGH TONIGHT AS
THE TROUGH TO OUR WEST CONTINUES TO DIG SOUTH AND UPSLOPE
DEEPENS OVER OUR REGION. PRECIPITATION IS EXPECTED TO REMAIN ALL
LIQUID RAIN BELOW 8000 FEET THROUGH THE DAYTIME HOURS, WITH A
TRANSITION TO SNOW POSSIBLE DOWN TO 7000 OR EVEN BRIEFLY 6000
FEET OVERNIGHT AND INTO THE EARLY MORNING HOURS OF FRIDAY. FOR
THE THE LOWER ELEVATIONS THOUGH, ACCUMULATIONS ARE EXPECTED TO
REMAIN LIGHT AND MAINLY CONFINED TO GRASSY AND ELEVATED
SURFACES. TRAVEL IMPACTS ARE NOT EXPECTED TONIGHT ACROSS THE
PLAINS, BUT MAY BE POSSIBLE OVER THE PALMER DIVIDE AND THE SAN
LUIS VALLEY EARLY FRIDAY MORNING NEAR SUNRISE. ACCUMULATIONS IN
THESE AREAS MAY REACH 2 TO 4 INCHES AT MOST ON ELEVATED
SURFACES, BUT ROADS ARE EXPECTED TO STAY WET THROUGH MUCH OF THE
NIGHT.
TOMORROW..
NEAR FREEZING TEMPERATURES EARLY IN THE MORNING MAY HELP TO CHANGE
SOME RAIN OVER TO FLURRIES AND LIGHT SNOW FOR SOME AREAS, BUT TRAVEL
IMPACTS AND ACCUMULATIONS ARE EXPECTED TO REMAIN CONFINED TO THE
HIGHER TERRAIN. ANOTHER PUSH OF SHORTWAVE ENERGY IN THE TROUGH TO
OUR WEST PUSHES PAST US THROUGHOUT THE MORNING AND EARLY AFTERNOON
HOURS, KEEPING PRECIPITATION CHANCES ALIVE OVER THE HIGH COUNTRY
THROUGH MUCH OF THE DAY. WITH THE BETTER FORCING DRIFTING SOUTH
THOUGH, CHANCES COME TO AN END FROM NORTHEAST TO SOUTHWEST OVER THE
PLAINS THROUGHOUT THE MORNING AND EARLY AFTERNOON. THIS NEXT PUSH OF
ENERGY DOES BRING IN SOME BETTER SNOW CHANCES FOR THE SAN JUANS LATE
TOMORROW MORNING INTO SATURDAY MORNING THOUGH, WHICH WILL
DEFINITELY HELP THEM TO NOT FEEL SO LEFT OUT. QPF TOTALS HAVE
COME DOWN JUST SLIGHTLY OVER THE SAN JUANS WITH THIS MODEL RUN,
SO HAVE HELD OFF ON ADVISORIES ONCE AGAIN, BUT TOTALS LOOK TO
BE IN THE 6 TO 10 INCH RANGE OVER THE SAN JUANS FOR TOMORROW. AS
CLEARING HAPPENS ON OUR PLAINS THOUGH, DAYTIME HIGHS LOOK TO
CLIMB BACK INTO THE 50S AND LOW 60S WITH LIGHT WINDS. OVERNIGHT
LOWS TOMORROW NIGHT ARE ALSO EXPECTED TO DIP DOWN CLOSE TO
FREEZING UNDER CLEARING SKIES ON THE PLAINS. FOR NOW, HAVE HELD
OFF ANY FREEZE HIGHLIGHTS, GIVEN THAT TEMPERATURES LOOK TO ONLY
BRIEFLY APPROACH THE FREEZING MARK ACROSS THE PLAINS.
LONG TERM /SATURDAY THROUGH THURSDAY/
ISSUED AT 110 PM MDT THU APR 30 2026
SATURDAY..
RIDGING DEVELOPS FOR SATURDAY AND INTO THE BEGINNING OF NEXT WEEK.
REMNANTS OF THE WEAK SHORTWAVE LOOK TO LINGER OVER THE FOUR CORNERS
REGION FOR A BIT, HELPING TO KEEP CHANCES FOR ISOLATED TO SCATTERED
SHOWERS AND THUNDERSTORMS OVER THE HIGH COUNTRY AND OUR SOUTHERN
PLAINS. CONVECTION DOES NOT LOOK TO BE SEVERE, BUT ANY STORMS THAT
DO DEVELOP SHOULD MANAGE TO BRING WETTING RAINS. ON THE PLAINS,
PRECIPITATION IS NOT EXPECTED, AND DAYTIME HIGHS LOOK TO BE NEAR
NORMAL FOR THIS TIME OF YEAR. MOST LOWER ELEVATION LOCATIONS LOOK TO
WARM INTO 60S AND 70S WITH FAIRLY WEAK WINDS.
SUNDAY ONWARDS..
RIDGING CONTINUES INTO SUNDAY AND MONDAY, ALLOWING OUR WARMING AND
DRYING TREND TO CONTINUE. HIGHS LOOK TO RISE INTO THE 70S AND 80S ON
THE PLAINS FOR BOTH SUNDAY AND MONDAY. CHANCES FOR SHOWERS AND
THUNDERSTORMS CONTINUE, ESPECIALLY ON MONDAY, AS MODELS PUSH A LOW
ONSHORE OVER CALIFORNIA AND MOIST SOUTHWEST FLOW INCHES TOWARDS OUR
FORECAST AREA. MODELS STILL SHOW A LOT OF DISAGREEMENT ABOUT THE
TRACK AND PROGRESSION OF THIS SYSTEM, BUT IN GENERAL IT LOOKS TO
WEAKEN BEFORE MAKING ITS WAY TOWARDS THE FOUR CORNERS REGION TOWARDS
TUESDAY OR WEDNESDAY. AS IT COMES THROUGH, CHANCES FOR A COOLER AND
WETTER PATTERN WILL LIKELY EMERGE DEPENDING ON ITS TRACK AND TIMING.
