...SIGNIFICANT CHANGE IN WEATHER CONDITIONS TUESDAY THROUGH FRIDAY
AS A COLD AND POWERFUL STORM SYSTEM SWEEPS THROUGH THE REGION...

A STRONG LOW PRESSURE SYSTEM WILL WORK THROUGH THE GREAT BASIN ON
TUESDAY THEN DROP SLOWLY SOUTHWARD ACROSS EASTERN UTAH AND WESTERN
COLORADO TUESDAY NIGHT THROUGH WEDNESDAY NIGHT. THE STORM CENTER
WILL LINGER NEAR THE FORECAST AREA THROUGH MUCH OF THE WEEK
BRINGING PROLONGED COOL AND UNSETTLED WEATHER. THIS SYSTEM WILL
BRING AN END TO A PERIOD OF MILD AND DRY CONDITIONS ACROSS THE
REGION.

STRONG GUSTY WINDS WILL DEVELOP AHEAD OF THIS STORM ON TUESDAY.
SHOWERS AND THUNDERSTORMS MAY DEVELOP DURING THE AFTERNOON...
MAINLY OVER THE MOUNTAINS WHILE MOST VALLEYS WILL REMAIN DRY. A
FIRE WEATHER WATCH HAS BEEN ISSUED FOR MUCH OF WESTERN COLORADO
WHERE FUELS ARE CRITICALLY DRY.

THE ASSOCIATED STRONG COLD FRONT WILL PUNCH THROUGH THE FORECAST
AREA TUESDAY NIGHT BRINGING A CHANCE OF SNOW TO ALL MOUNTAINS AS
WELL AS HIGHER VALLEYS. SIGNIFICANT SNOW ACCUMULATIONS ARE
POSSIBLE...ESPECIALLY WEDNESDAY THROUGH FRIDAY.

AS COLDER AIR FILTERS OVER THE AREA ON WEDNESDAY...TEMPERATURES
WILL PLUMMET. WEDNESDAY NIGHT...WIDESPREAD SUB-FREEZING
TEMPERATURES ARE POSSIBLE WHICH WOULD THREATEN TENDER VEGETATION.

THERE IS HIGH CONFIDENCE ON THE TIMING OF THE ONSET OF THE STORM.
HOWEVER IMPORTANT DETAILS ARE STILL NOT RESOLVED...ESPECIALLY
STORM TOTAL SNOW AMOUNTS. CONTINUE TO MONITOR YOUR FAVORITE
