.SHORT TERM...TONIGHT THROUGH SUNDAY.

FIRST MAJOR WAVE OF MOISTURE IS MOVING THROUGH THE REGION AT THIS
TIME. TEMPERATURES HAVE WARMED AS EXPECTED TODAY. TEMPERATURES ARE
NOT QUITE AS WARM UNDER THE HEAVIER AREAS OF PRECIPITATION DUE TO
EVAPORATIVE COOLING EFFECTS. PRELIMINARY AMOUNTS ARE FAIRLY LIGHT
SO FAR. HAVE RECEIVED SOME REPORTS OF UP TO 4 INCHES IN THE ISLAND
PARK AREA AND IN THE CENTRAL MOUNTAINS FROM KETCHUM TO STANLEY.
EXPECT THE BETTER SNOW AMOUNTS TO LAST FROM THIS AFTERNOON THROUGH
FRIDAY WHEN THE COLD FRONT BLASTS THROUGH THE AREA. A FOOT OR MORE
OF SNOW REMAINS LIKELY IN THE WARNING AREAS ABOVE 5500 FEET FROM
KETCHUM TO STANLEY...IN THE UPPER SNAKE HIGHLANDS AND IN THE
EASTERN HIGHLANDS INCLUDING THE WASATCH. CONSEQUENTLY...HAVE
EXTENDED THE WARNING SOUTH FROM THE ISLAND PARK AREA TO THE
WASATCH. THE VALLEYS WILL PROBABLY SEE MUCH LOWER ACCUMULATIONS
DUE TO CONSIDERABLE WARM AIR THAT IS BEING PUMPED INTO THE REGION.
BREEZY CONDITIONS WILL ACCOMPANY THIS SYSTEM AS WELL SO EXPECT
CONSIDERABLE BLOWING AND DRIFTING SNOW IN THE WARNING AREA.
CONDITIONS ARE EXPECTED TO BE WINDY IN THE SNAKE PLAIN AS WELL AND
A WIND ADVISORY MAY BE NEEDED LATER THIS EVENING AND FOR FRIDAY
FOR THE UPPER SNAKE PLAIN. EXPECT TEMPERATURES TO HOLD STEADY OR
EVEN RISE THROUGHOUT THE NIGHT AS 850MB WET BULB TEMPERATURES
CLIMB TO NEAR +4C BY MORNING. ONCE THE SYSTEM MOVES AWAY FROM THE
AREA FRIDAY NIGHT...VERY COLD AIR USHERS INTO THE REGION WHICH
WILL PERSIST THROUGH THE WEEKEND.

DNV

.LONG TERM...SUNDAY NIGHT THROUGH THURSDAY.  AN ACTIVE WEATHER
PATTERN IS EXPECTED FOR EARLY NEXT WEEK. EASTERN IDAHO WILL REMAIN
IN A RATHER FAST MOVING NW FLOW ALOFT AS RIDGE BUILDS ALONG THE WEST
COAST.  IT APPEARS THAT THE WITH THIS PATTERN...THE MTNS WILL GET
MOST OF THE PRECIP. IN THIS PATTERN...THE FAR WESTERN PART OF THE
CENTRAL MTNS AND SOUTHERN/SE MTN RANGES WILL SEE THE BEST HIGHEST
AMTS.  WITH THE SYSTEM COMING THROUGH ON MONDAY...WE WILL SEE A
LITTLE BETTER CHANCE OF PRECIP IN THE SNAKE PLAIN...ESPECIALLY ALONG
THE SOUTHERN AND EASTERN FRINGES. WITH COLD TEMPS IN PLACE...EXPECT
AN ALL SNOW EVENT.  FOR TUESDAY AND WEDNESDAY...PRECIP CHANCES DROP
OFF IN THE SNAKE PLAIN WITH CONTINUE HIGHER CHANCES IN THE MTNS. THE
NEXT BEST CHANCE FOR THE ENTIRE AREA INCLUDING THE SNAKE PLAIN WILL
BE STARTING THURSDAY. AS FAR AS WINDS...BREEZY CONDITIONS CAN BE
ANTICIPATED THROUGHOUT THE WEEK. DESPITE NW FLOW ALOFT...SOME
WARMING CAN BE EXPECTED DURING THE DAYTIME. WITH MANY AREAS GETTING
ABOVE FREEZING BUT TRYING TO STAY UNDER 40.
