.SHORT TERM...COLD FRONT FROM THE NORTHWEST BROUGHT SCATTERED LIGHT
SNOW SHOWERS TO IDAHO MOUNTAIN ZONES DURING THE NIGHT.  WEB CAMS
SHOWED SNOW SHOWERS NORTH OF BOISE AT BOTH BOGUS BASIN AND HORSESHOE
BEND HILL...AND ALSO AT MCCALL/ID.  KCBX RADAR TRACKED SNOW SHOWERS
BOTH NORTH AND SOUTH OF THE SNAKE BASIN...AND EVEN A FEW FLAKES IN
THE TREASURE VALLEY.  BOGUS BASIN RECEIVED ABOUT AN INCH OF NEW SNOW
BUT OTHER MOUNTAIN SITES GOT A DUSTING AT MOST...ALTHOUGH RADAR
SUGGESTED A LITTLE MORE IN THE OWYHEE MOUNTAINS.  THE FRONT ALSO
BROUGHT SUSTAINED NORTHWEST WINDS 15 TO 30 MPH WITH GUSTS 35 TO 40
MPH.  AT 10Z BOTH THE FRONT AND STRONGEST WINDS WERE IN THE EASTERN
UPPER TREASURE VALLEY AND WESTERN MAGIC VALLEY.  THOSE AREAS WILL
HAVE THE STRONGEST WINDS TODAY...JUST BELOW ADVISORY LEVELS.  ERN-
MOST ZONES WILL ALSO HAVE A CHANCE OF LIGHT SNOW SHOWERS TODAY...
THESE SHOULD END BY SUNSET.  AIR MASS WILL BE DRIER TODAY UNDER
STRONG NORTHERLY FLOW ALOFT.  SURFACE WINDS WILL DECREASE TONIGHT
AND WITH CLEAR SKIES AND DRY AIR TEMPS WILL BE NOTICEABLY COLDER...
BUT NOT QUITE AS COLD AS FORECAST BY PREVIOUS MODELS.  MET MOS
GUIDANCE NOW LOOKS TOO COLD FOR TONIGHT...MAV GUIDANCE PREFERRED.
BRIGHT SUNSHINE AND CONTINUED COOL WEDNESDAY BUT WITH MUCH LESS
WIND AS COASTAL UPPER RIDGE BEGINS TO NOSE INLAND.

.LONG TERM...WEDNESDAY NIGHT THROUGH TUESDAY. UPPER LEVEL HIGH WITH
ITS AXIS STAYING ROUGHLY OVER CALIFORNIA WILL DOMINATE THE MID-LONG
TERM. A WEAK SHORTWAVE THAT THE ECMWF HAD BEEN HINTING AT FOR FRIDAY
IS NO LONGER VISIBLE IN THE LATEST RUN...WHICH IS MORE IN LINE WITH
THE DRIER GFS.  THEREFORE CONFIDENCE IS HIGH IN DRY CONDITIONS
THROUGH THE ENTIRE PERIOD. TEMPERATURES ARE EXPECTED TO GRADUALLY
RISE TO 10 PLUS DEGREES ABOVE NORMAL FOR SATURDAY AND BEYOND.

&&

.AVIATION...VFR WITH CLEARING SKIES. GUSTY WEST SURFACE WINDS TO
NEAR 30 KTS IN THE MAGIC VALLEY ARE EXPECTED TO CONTINUE THROUGH
04/06Z. GUSTY NORTHWEST SURFACE WINDS TO NEAR 25 KTS EXPECTED NEAR
KBKE AND THE REST OF THE LOWER SNAKE PLAIN BETWEEN 03/17Z AND
04/06Z. WINDS ALOFT NEAR 10K FT MSL...NORTH 15-20 KTS.
