NORTH TO SOUTH ORIENTED SURFACE FRONT WILL PROGRESS EASTWARD ACROSS
THE FORECAST AREA THIS AFTERNOON INTO EARLY THIS EVENING. AHEAD OF
THIS FRONT...STRONG SOUTH WINDS HAVE DEVELOPED. WINDS WILL BECOME
MORE SOUTHWEST BEHIND THE FRONT...BUT WILL REMAIN QUITE STRONG UNTIL
AFTER TROUGH PASSAGE LATE TONIGHT. WITH THIS STRONG FLOW AND FAST
STORM MOTION THE THUNDERSTORM OUTFLOWS WILL EASILY REACH WARNING

FOR THE ENTIRE FORECAST AREA THROUGH 5 PM MDT THIS EVENING. ALSO...
STRONG GRADIENT WINDS HAVE RESULTED IN GUSTS IN EXCESS OF 75 MPH OVER

THE HIGH WIND WARNING THAT WAS ISSUED EARLIER WILL CONTINUE THROUGH
MIDNIGHT TONIGHT.

SNOW LEVELS REMAIN QUITE HIGH TODAY WITH RAIN REPORTED ON RED
MOUNTAIN PASS AT 2 PM MDT WITH THE SNOW LEVEL AT 9500 FEET OR ABOVE.
THE SNOW LEVEL WILL LOWER ONCE THE COLD FRONT MOVES EAST OF
THE AREA. THE FRONT IS TIMED TO REACH THE RED MOUNTAIN AREA BETWEEN 4
AND 5 PM THEN EAST OF THE CONTINENTAL DIVIDE BY LATER THIS EVENING.
THE STRONG CONVECTION WILL PUSH SNOW LEVELS LOWER AT TIMES...HOWEVER
SNOW ACCUMULATIONS WILL BE LIGHT BELOW AROUND 10000 FEET UNTIL AFTER
THE COLD FRONT MOVES EAST.

MINOR FLOODING HAS BEEN REPORTED ON DRY CREEK IN THE HAYDEN AREA.
WITH THE WARM TEMPERATURES RESULTING IN GOOD SNOWMELT...AND
ADDITIONAL PCPN EXPECTED THROUGH THU...OTHER STREAMS MAY REACH
BANKFULL LEVELS. WILL KEEP PRESENT FLOOD WARNING FOR THE HAYDEN AREA

LEVEL FALLS LOW ENOUGH THE FLOW MAY DECREASE FOR A LITTLE WHILE.

LATE TONIGHT AND THURSDAY...SNOW ACCUMULATION WILL INCREASE ONCE THE
FRONT MOVES EAST AND THE MAIN UPPER LEVEL TROUGH MOVES OVERHEAD LATE
TONIGHT. BY MORNING THE SNOW LEVEL IS EXPECTED TO BE AROUND 6500
FEET. THE FLOW WILL SHIFT TO A MORE NORTHWESTERLY DIRECTION BY
EARLY THU...WITH THE FAVORED AREAS SHIFTING TO THE NORTH AND
CENTRAL MOUNTAINS. BOTH THE NAM AND THE GFS ROTATE ANOTHER LOBE
AROUND THE LOW AND ACROSS THE AREA THU THROUGH THU EVENING. THIS
WILL KEEP THE ACTION GOING MOST AREAS...DIMINISHING FROM THE FAR
SOUTHWEST. WILL LET PRESENT WINTER HILITES RIDE AT THIS TIME AS THEY
LOOK TO BE IN GOOD SHAPE.

THURSDAY NIGHT THROUGH FRIDAY...PCPN WILL DIMINISH FROM THE WEST
THU NIGHT AND FRI. BY FRI AFTERNOON SHOWERS WILL BE LIMITED TO
MAINLY THE NORTH AND CENTRAL MOUNTAINS. WITH SKIES CLEARING FROM THE
SOUTHWEST.

LONG TERM (FRIDAY NIGHT THROUGH WEDNESDAY)...DRY AND WARMER
CONDITIONS WILL DEVELOP FOR THE WEEKEND AS A RIDGE OF HIGH PRESSURE
MOVES OVER THE AREA AND THE NEXT TROUGH DEVELOPS OFF THE PACIFIC
COAST. THE WARMER TEMPS WILL RESULT IN INCREASED RUNOFF AND AREA
STREAMS AND RIVERS WILL HAVE TO BE MONITORED. THE RIDGE BEGINS TO
BREAK DOWN ON MON AS PIECES OF ENERGY GET EJECTED FROM THE TROUGH. AT
THIS TIME IT LOOKS LIKE MOST OF THIS ENERGY WILL REMAIN NORTH OF THE
