.SHORT TERM...TONIGHT THROUGH MONDAY...WINDS REMAIN GUSTY THIS
AFTERNOON...ESPECIALLY IN THE WESTERN MAGIC VALLEY WHERE A WIND
ADVISORY REMAINS IN EFFECT. WINDS HAVE ALREADY DECREASED
CONSIDERABLY IN THE TREASURE VALLEY AS SURFACE HIGH PRESSURE MOVES
IN FROM OREGON. THE STRONGER WINDS IN TWIN FALLS/JEROME WILL
WEAKEN THROUGH THE REMAINDER OF THE AFTERNOON. A HIGH PRESSURE
RIDGE WILL BUILD INTO THE REGION TONIGHT THROUGH MONDAY...
RESULTING IN DRY CONDITIONS AND LIGHT WINDS. THIS WILL ALSO LEAD
TO A WARMING TREND...WITH HIGHS UP 4-8 DEGREES ON SUNDAY AND
ANOTHER 4-8 DEGREES ON MONDAY. TEMPERATURES MAY APPROACH RECORDS
AT A FEW LOCATIONS ON MONDAY.

.LONG TERM...MONDAY NIGHT THROUGH SATURDAY...THE LONG TERM IS
EXPECTED TO BE FAIRLY ACTIVE WITH A SERIES OF TROUGHS THAT WILL
EACH BRING A COLD FRONT...GUSTY WINDS...AND A CHANCE OF PRECIP.
MONDAY NIGHT IS EXPECTED TO REMAIN DRY AHEAD OF THE FIRST OF THESE
TROUGHS MOVING THROUGH ON TUESDAY. WITH THE COLD FRONT EAST OF
MOST AREAS BY MID DAY TUESDAY...GUSTY WINDS IN THE AFTERNOON ARE
EXPECTED FOR MOST AREAS...ESPECIALLY THE TREASURE AND MAGIC
VALLEYS. PRECIP CHANCES WILL EXIST MAINLY FOR THE MOUNTAIN
AREAS...WITH NO SIGNIFICANT ACCUMULATIONS OF RAIN/SNOW EXPECTED. A
QUICK BREAK IN ACTIVITY ON WEDNESDAY WILL STILL HAVE COOLER/NEAR
NORMAL TEMPERATURES. MODELS ARE SHOWING A STRONGER TROUGH/FRONT
MOVING IN EARLY THURSDAY WITH PRECIP ONCE AGAIN POSSIBLE IN THE
MOUNTAINS. CURRENT MODEL RUNS ARE SUGGESTING STRONGER WINDS AND A
GREATER POTENTIAL FOR THUNDERSTORMS THURSDAY AFTERNOON...BUT
CONFIDENCE IS LOW AT THIS TIME. FOR FRIDAY AND BEYOND...BOTH THE
GFS AND ECMWF ARE SHOWING A LARGER CLOSED LOW DIGGING SOUTH ALONG
THE PACNW COAST...BUT THE GFS IS MORE PROGRESSIVE AND SWIFT WITH
