SHORT TERM /THROUGH THURSDAY/
ISSUED AT 148 AM MDT WED SEP 17 2025
ANOTHER WAVE OF VORTICITY IS CURRENTLY MOVING THROUGH THE AREA
LEADING TO MORE SHOWERS AND ISOLATED STORMS BUT NOT NEARLY AT
THE INTENSITY AS BEFORE. MUCAPE AROUND 500 J/KG REMAINS IN PLACE
SO SOME EMBEDDED STORM POTENTIAL STILL REMAINS BUT SEVERE
WEATHER IS UNLIKELY AT THIS TIME. THE BIGGEST CONCERN AT THIS
TIME WILL BE ADDITIONAL FLOODING ISSUES ESPECIALLY ACROSS
NORTHERN PORTIONS OF THE AREA WHERE SOME FLOODING HAS ALREADY
BEEN REPORTED. ADDITIONAL MINOR FLOODING DOES STILL REMAIN
POSSIBLE AS PWATS OF 1.2 TO 1.4 REMAIN IN PLACE ACROSS THE AREA.
THE BATCH OF RAINFALL THAT IS CURRENTLY ACROSS EASTERN COLORADO
WILL MOVE ACROSS THE AREA SLOWLY WANING IN INTENSITY AS SOME
DRIER MID LEVEL AIR PUSHES IN. ALSO WATCHING FOR THE POTENTIAL
FOR SOME FOG DEVELOPMENT ACROSS THE AREA, STRATUS SEEMS TO BE
THE MORE LIKELY OPTION DUE TO THE ONGOING SHOWERS AND ADDITIONAL
CLOUD COVER FROM THE SHOWERS BUT SOME PATCHES OF DENSE FOG
CAN'T BE COMPLETELY RULED OUT WHERE CLOUDS ARE ABLE TO BREAK FOR
PERIODS OF TIME.
FOR THE REMAINDER OF THE DAY OVERALL RAIN IS FORECAST TO BECOME LESS
WIDESPREAD. HOWEVER DO CONTINUE TO SEE SOME LOW LEVEL OMEGA IN PLACE
AROUND 5 MICROBARS WHICH MAY LEAD TO SOME SPOTTY LIGHT SHOWERS
AND/OR DRIZZLE MAINLY ALONG AND NORTH OF INTERSTATE 70. CLOUD COVER
DOES LOOK TO LINGER A BIT LONGER ACROSS THE NORTH SO HAVE LOWERED
HIGH TEMPERATURES INTO THE UPPER 60S TO LOW 70S; FURTHER SOUTH HIGHS
IN THE MID 70S TO LOW 80S ARE FORECAST DUE TO BREAKS IN THE CLOUDS
CONTINUING.
A LARGE LOW PRESSURE SYSTEM CURRENTLY SPINNING ACROSS WYOMING WILL
SEND ANOTHER BATCH OF ENERGY THROUGH THE AREA LATE THIS AFTERNOON
AND THROUGH THE EVENING LEADING TO ANOTHER ROUND OF SHOWERS AND
THUNDERSTORMS. THANKFULLY THIS BATCH LOOKS TO LIE ALONG AND SOUTH OF
INTERSTATE 70. THERE IS THE POTENTIAL FOR HAIL TO PING PONG BALL AND
DAMAGING WINDS TO 60 MPH MAINLY ALONG AND SOUTH OF INTERSTATE 70 AS
WIND SHEAR IS A BIT BETTER TODAY. THE BIG QUESTION FOR SEVERE
WEATHER IS IF STORMS WILL REMAIN DISCRETE OR AS STRONG AS THEY MOVE
INTO THE AREA AS THEY SHOULD CLUSTER INTO AN EASTWARD MOVING MCS. AT
THIS TIME NOT SEEING ANY CONCERNS FOR FLOODING AS CORFIDI
VECTORS APPEAR TO BE VERY HIGH AND PWATS ARE FORECAST TO BE LESS
THAN ONE INCH. SOME LIGHT SHOWERS REMAIN POSSIBLE ACROSS
NORTHERN PORTIONS OF THE AREA AS WELL OVERNIGHT BEFORE ENDING AS
WE HEAD INTO THURSDAY MORNING.
LONG TERM /THURSDAY NIGHT THROUGH TUESDAY/
ISSUED AT 124 PM MDT TUE SEP 16 2025
THE LONG-TERM WILL START OFF WITH A LOW PRESSURE SYSTEM OVER THE
NORTHERN PLAINS EXTENDING INTO THE CWA. THIS WILL KEEP THURSDAY'S
TEMPERATURES FAIRLY COOL, IN THE 70S, AND GIVE US A MODERATE CHANCE
OF SEEING SHOWERS AND STORMS THROUGHOUT THE DAY. FRIDAY, A RIDGE
STARTS BUILDING INTO THE REGION FROM THE WEST, SLOWLY PUSHING THE
LOW OUT DURING THE DAY FRIDAY, BUT PUTTING US UNDER NORTHWESTERLY
FLOW. THIS PATTERN COULD LAST OVER THE WEEKEND, CONTINUING THE
UNSETTLED WEATHER WE'VE BEEN SEEING AND WARMING US INTO THE 80S, OR
A LOW OVER THE NORTHWESTERN CONUS WILL FLATTEN THE RIDGE AND LEAD TO
ZONAL FLOW. THE ZONAL FLOW WOULD EQUATE TO LESS PRECIPITATION
POTENTIAL, BUT TEMPERATURES WOULD LARGELY REMAIN IN 70S.
LONG RANGE GUIDANCE IS SHOWING A POTENT LOW COMING IN FROM THE
NORTHWEST CONUS SOME TIME BETWEEN SUNDAY EVENING AND TUESDAY
MORNING, LEADING TO OUR NEXT POTENTIAL FOR ORGANIZED CONVECTION.
THROUGHOUT THE LONG-TERM, LOWS LOOK TO COOL INTO THE LOW TO MID 50S,
ALTHOUGH THE WESTERN CWA COULD SEE SOME UPPER 40S.
AVIATION /06Z TAFS THROUGH 06Z THURSDAY/
ISSUED AT 1112 PM MDT TUE SEP 16 2025
SCATTERED SHOWERS AND ISOLATED THUNDERSTORMS WILL CONTINUE
THROUGH THE OVERNIGHT HOURS AND MAY BRIEFLY IMPACT EITHER KGLD
OR KMCK. LOW CEILINGS WILL ALSO DEVELOP WITH IFR LIKELY BY
SUNRISE AND THEN SLOWLY BURNING OFF WEDNESDAY MORNING. SOME FOG
IS POSSIBLE AROUND KMCK BUT CONFIDENCE IS LOW. A RETURN TO VFR
EXPECTED AT BOTH TERMINALS BY MID TO LATE MORNING AND CONTINUING
THROUGH THE REMAINDER OF THE TAF PERIOD.
HYDROLOGY
ISSUED AT 151 AM MDT WED SEP 17 2025
ANOTHER ROUND OF SHOWERS AND STORMS MOVING THROUGH EASTERN
COLORADO AS OF 2AM MT ARE MOVING TOWARDS AREAS OF SW NEBRASKA
AND NW KANSAS THAT HAS ALREADY SEEN SOME FLOODING THIS EVENING.
NOT ANTICIPATING ANY ADDITIONAL FLASH FLOODING CONCERNS WITH
THIS ACTIVITY BIT WILL NOT HELP THE SITUATION AS ADDITIONAL
EXACERBATION OF FLOODED AREAS ESPECIALLY ACROSS HITCHCOCK AND
RED WILLOW COUNTIES REMAIN. AM WATCHING CLOSELY RIVER GAUGES AS
WELL ACROSS ACROSS SW NEBRASKA AS SOME HAVE SHOWN SOME RISES BUT
CURRENTLY REMAIN BELOW MINOR FLOODING STAGE. PALISADE GAUGE IS
THE ONE OF CURRENT CONCERN AS OF TYPING THIS AS IT CONTINUES TO
RISE AND WOULD FLOW INTO THE REPUBLICAN RIVER.
WEDNESDAY EVENING, WE ARE EXPECTING ANOTHER ROUND OF EFFICIENT RAIN
PRODUCING STORMS IN THE SOUTHER CWA, MAINLY ALONG AND SOUTH OF U.S.
40. THE RISK FOR FLOODING WILL HEAVILY DEPEND ON HOW THE RAIN
TONIGHT PANS OUT. IF THIS LOCATION GETS 0.5-1 INCH OF RAIN,
CONFIDENCE IN FLOODING WOULD INCREASE TO ABOUT 35%, OTHERWISE IT WILL
HOVER AROUND 15-20%. THIS WOULD BE AN OVERNIGHT FLOODING EVENT, IF
IT WERE TO HAPPEN, POTENTIALLY EVOLVING INTO THURSDAY MORNING.
