.DISCUSSION...

A STRONG TEMPERATURE INVERSION WILL PERSIST AT LEAST THROUGH EARLY
TO MID AFTERNOON TODAY WITH LOW TEMPERATURES THIS MORNING BOTTOMING
OUT TO 25 TO 35 BELOW ZERO SHORTLY AFTER SUNRISE THIS MORNING IN THE
VALLEYS. A POWERFUL WINTER STORM IS EXPECTED TO ENSUE LATE THIS
AFTERNOON THROUGH MID DAY SATURDAY AS A STRONG STEERING FLOW OFF
THE PACIFIC DELIVERS 6 TO 18 INCHES TO THE WESTERN VALLEYS AND
UPWARDS OF 18 TO 28 INCHES IN THE MOUNTAINS. SNOWFALL RATES OF 1/2
TO 3/4 OF AN INCH ARE EXPECTED DURING THIS TIME FRAME IN THE
MOUNTAINS WITH SOMEWHAT LESS INTENSITY OVERALL IN THE VALLEYS.
SNOWFALL WILL FIRST BREAK OUT IN THE MOUNTAINS LATE THIS AFTERNOON
AND WORK ITS WAY INTO THE VALLEYS BY SUNSET THIS EVENING. SNOWFALL
WILL INCREASE IN INTENSITY THIS EVENING AND PERSIST THROUGH THE
NIGHT TONIGHT. THERE WILL BE A SUBTLE DECREASE IN SNOWFALL
ACTIVITY FRIDAY, BUT WEST FACING SLOPES SHOULD MAINTAIN THERE
MODERATE TO HEAVY SNOWFALL FRIDAY. MODERATE TO HEAVY SNOWFALL WILL
ENSUE EVERYWHERE ONCE AGAIN FRIDAY NIGHT INTO SATURDAY MORNING. WE
SHOULD WITNESS ONE LAST SNOW SQUALL AS THE GRAND FINALE FOR THIS
EVENT AROUND MID DAY SATURDAY AS A PACIFIC COLD FRONT TRACKS
ACROSS FAR WEST WYOMING. LESS INTENSIVE SNOW SHOWERS WILL CONTINUE
SATURDAY AFTERNOON AND NIGHT, ESPECIALLY ON NORTHWEST FACING
SLOPES AS MOIST NORTHWEST FLOW ENSUES BEHIND THE FRONT. INCREASING
WIND WITH THIS SNOW EVENT WILL LEAD TO SIGNIFICANT BLOWING AND
DRIFTING SNOW.
