UPDATE
ISSUED AT 144 PM MST THU FEB 20 2025
AFTER A CLOSER LOOK AT THE SNOW FORECAST FOR TONIGHT, THERE DOES
LOOK TO BE A POTENTIAL FOR A NARROW STRIP OF SEVERAL INCHES;
MAYBE EVEN CLOSE TO 6 INCHES. DUE TO THE NARROW NATURE OF THE
SNOW FALL, AND A LACK OF CONFIDENCE OF WHERE THE BAND WILL SET
UP, WILL NOT BE ISSUING AN ADVISORY. THE FAVORED AREA FOR THE
SNOWBANDS TO FORM IS OVER THE WEST HALF OF THE FORECAST AREA.
SHORT TERM /THROUGH SATURDAY NIGHT/
ISSUED AT 124 PM MST THU FEB 20 2025
LATEST UPPER AIR ANALYSIS SHOWS A CLOSED LOW OVER THE GREAT BASIN.
AHEAD OF IT CLOUD COVER WAS MOVING SOUTHEAST OVER THE FORECAST
AREA. AT THE SURFACE BREEZY SOUTH WINDS WERE HELPING WARM
TEMPERATURES FROM WHAT WE HAD YESTERDAY.
TONIGHT CLOUD COVER WILL PERSIST OVER THE FORECAST AREA.
MEANWHILE THE CLOSED LOW WILL CONTINUE TO MOVE EAST, MOVING
TOWARD THE FORECAST AREA. AHEAD OF IT CORRIDORS OF LIFT WILL
FORM. WITHIN THE LAYER THE LIFT WILL OCCUR IN THE ENVIRONMENT
IS NEUTRAL TO SLIGHTLY UNSTABLE, ALLOWING THE ENVIRONMENT TO
MORE EFFICIENTLY USE THE LIFT. THE BIG QUESTION IS NOT IF, BUT
WHERE WILL THESE NARROW BANDS SET UP. THE CURRENT FORECAST IS
REFLECTIVE OF THE GENERAL MODEL CONSENSUS. HOWEVER THIS MAY NOT
BE THE CASE. THE BEST TIME FOR SNOW TO FORM WILL BE DURING THE
OVERNIGHT HOURS INTO THE EARLY MORNING. SNOW WILL END FROM WEST
TO EAST OVERNIGHT THROUGH FRIDAY MORNING.
GIVEN THE STABILITY OF THE ENVIRONMENT, THERE COULD BE WINDOWS OF AN
INCH AN HOUR SNOWFALL RATES, YIELDING A NARROW CORRIDOR OF AN
INCH OR SO OF SNOW.
OVERNIGHT THE WIND CHILLS WILL FALL TO AROUND 15 BELOW ZERO. THE
COLDEST WIND CHILLS WILL BE OVER THE EASTERN PART OF THE FORECAST
AREA. CLOUD COVER WILL HELP KEEP THE TEMPERATURES WARMER THAN
OTHERWISE. MOST OF THE FORECAST AREA WILL BE NEAR OR BELOW -15 FOR
A WIND CHILL. FOR SIMPLICITY HAVE PLACED THE ENTIRE FORECAST AREA
IN A COLD WEATHER ADVISORY, EVEN THOUGH SOME COUNTIES MAY APPROACH
BUT NOT MEET THE CRITERIA.
FRIDAY THE WIND CHILLS WILL IMPROVE MID MORNING. MEANWHILE THE SNOW
WILL SLIDE EAST THROUGH THE MORNING, EXITING THE FORECAST AREA
AROUND NOON.
LONG TERM /SUNDAY THROUGH THURSDAY/
ISSUED AT 124 PM MST THU FEB 20 2025
SATURDAY THROUGH THURSDAY WILL BE DRY. TEMPERATURES WILL REBOUND TO
POTENTIALLY RECORD VALUES MONDAY AS A SHORT WAVE RIDGE BUILDS
IN.
MID WEEK AN UPPER LEVEL SHORT WAVE TROUGH WILL MOVE ACROSS THE
NORTHERN PLAINS. AS IT DOES SO THE BASE OF THE TROUGH WILL MOVE
OVER THE FORECAST AREA. WINDS ROUNDING THE BASE OF THE TROUGH WILL
BE WINDY. LATEST MODEL PROBABILITY SHOWS 30% OR LESS FOR SUSTAINED
WINDS GREATER THAN 30 MPH. PROBABILITY FOR WIND GUSTS OF 50 MPH OR
HIGHER IS 20% OR LESS. THE PATTERN DOES LOOK FAVORABLE FOR STRONG
WINDS TO OCCUR, SO THE PROBABILITIES MAY INCREASE AS THIS DAY NEARS.
DURING THE LATTER HALF OF THE WEEK TEMPERATURES WILL BE CLOSER TO
NORMAL DUE TO A COLD FRONT PASSAGE BEHIND THE UPPER LEVEL SHORT WAVE
TROUGH. FORECAST CONTINUES TO LOOK DRY FOR THE FRONTAL PASSAGE.
AVIATION /00Z TAFS THROUGH 00Z SATURDAY/
ISSUED AT 354 PM MST THU FEB 20 2025
LATEST GUIDANCE SUGGESTS THAT MVFR CLOUD COVER IS FORECAST TO
PERSIST AT KGLD THROUGH AROUND 05Z WITH OCCASIONAL FLURRIES.
ANY BLOWING SNOW THAT WAS ONGOING AT THIS TIME LOOKS TO END AS
THE SUNSETS AS WELL SO WILL MAINTAIN A P6SM FOR NOW. ALSO AM
WATCHING FOR LIGHT SNOW TO MOVE AGAIN TOWARDS SUNRISE. THERE IS
ALSO THE POTENTIAL FOR A SNOW BAND TO FORM AND IMPACT THE KGLD
TERMINAL. GUIDANCE IS ALL OVER THE PLACE CURRENTLY WITH THE
LOCATION OF IT SO WILL GO WITH A PROB30 TO INTRODUCE THIS
POTENTIAL FOR NOW. AS FOR KMCK; VFR CONDITIONS ARE CURRENTLY
FORECAST TO PREVAIL AND NOT SEEING ANY THREAT FOR SNOW AT THIS
TIME.
