AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE POCATELLO ID
234 AM MDT SUN SEP 25 2011

.DISCUSSION...WE WILL BE SEEING OUR RECENT SPELL OF VERY WARM
WEATHER COME CRASHING TO A HALT IN THE NEXT 24-36 HOURS. BREEZY
SOUTH TO SOUTHWEST WINDS WILL DEVELOP LATER TODAY WITH SUSTAINED
WINDS OF 15-25 MPH FORECAST. MOISTURE WILL INCREASE AS THE DAY
WEARS ON...WITH CLOUDS MOVING IN FROM THE WEST. THERE SHOULD JUST
BE ENOUGH INSTABILITY COMBINED WITH WHAT MOISTURE IS OUT THERE TO
KICK OFF AN ISOLATED AFTERNOON THUNDERSTORM IN WESTERN AREAS.
THERE IS STILL SOME DIFFERENCES IN HOW QUICKLY THE MODELS TRY AND
SWING THE SYSTEM THROUGH. THE NAM IS STILL SLOWER THAN THE OTHERS
BUT IS TRYING PLAY CATCH UP AT THE MOMENT. WE WILL SEE SHOWERS
SPREADING EASTWARD OVERNIGHT AS THE COLD FRONT RACES ACROSS
EASTERN IDAHO...WITH SOME LINGERING SHOWERS ACROSS THE NORTHERN
AND EASTERN MOUNTAINS MONDAY. THE FRONT WILL BE WELL EAST OF US
MONDAY BUT EXPECT BREEZY WEST TO SOUTHWEST WINDS IN SOME AREAS
ESPECIALLY THE SNAKE PLAIN. THE BIGGEST STORY SHOULD BE THE COOLER
TEMPERATURES TOMORROW...ALTHOUGH THAT MIGHT BE SOMEWHAT OF A
MISNOMER. HIGHS WILL BE IN THE 60S AND 70S FOR MORE POPULATED
AREAS AND 40S/50S IN THE MOUNTAINS. THAT IS ACTUALLY WHERE WE
SHOULD BE FOR THE END OF SEPTEMBER...COMPARED WITH THE 10-15
DEGREE ABOVE AVERAGE TEMPERATURES FROM THE PAST COUPLE OF DAYS.
MONDAY NIGHT WILL BE CHILLY WITH 30S AND 40S FOR THE MOST PART.
SOME OF THE HIGHER VALLEYS WILL LIKELY DROP INTO THE 20S. SOME
POCKETS OF FROST ARE ALSO POSSIBLE ACROSS PORTIONS OF THE SNAKE
PLAIN.

THE RIDGE REBUILDS ACROSS EASTERN IDAHO THROUGH MIDWEEK SIGNALING
THE RETURN OF ABOVE AVERAGE TEMPERATURES ALTHOUGH NOT QUITE AS
WARM AS THE RECENT SPELL. FOR TUESDAY AND WEDNESDAY...MOISTURE
WILL STREAM ACROSS NORTHERN AREAS FOR MAINLY SOME CLOUD
COVER...BUT A SHOWER IS NOT OUT OF THE QUESTION. BY THE END OF THE
WEEKEND AND INTO NEXT WEEKEND...ANOTHER SYSTEM MOVES THROUGH. THE
GFS IS SHOWING A LOT MORE MOISTURE AND MORE OF A DIRECT IMPACT
THAN WHAT THE ECMWF IS DOING. FOR NOW...THE FORECAST WILL REFLECT
A LITTLE COOLER WEATHER ALONG WITH SOME THREAT OF SHOWERS/STORMS
MAINLY OVER THE MOUNTAINS.  KEYES

&&

.AVIATION...VFR CONDITIONS ARE FORECAST TO CONTINUE THROUGH TONIGHT.
A COLD FRONT WILL PASS THROUGH THE REGION OVERNIGHT TONIGHT. WINDS
WILL BE ON THE INCREASE AHEAD OF THE FRONT AND WILL STAY ELEVATED
BEHIND THE FRONT. A FEW SHOWERS WILL BE POSSIBLE...BUT SHOULD REMAIN
IN THE CENTRAL MOUNTAINS AND ALONG THE DIVIDE. DMH

&&

.FIRE WEATHER...BREAKDOWN OF THE UPPER RIDGE WILL BEGIN LATE TODAY
AS A PACIFIC SYSTEM APPROACHES THE REGION. WINDS WILL INCREASE
ESPECIALLY THIS AFTERNOON AND EVENING. THE ELEVATED WINDS COMBINED
WITH DRY CONDITIONS AHEAD OF THE FRONT WARRANT A RED FLAG WARNING
FOR PORTIONS OF THE CENTRAL MOUNTAINS. A FEW SHOWERS AND
THUNDERSTORMS WILL BE POSSIBLE THIS AFTERNOON AND OVERNIGHT AHEAD OF
THE COLD FRONT...BUT LITTLE PRECIPITATION IS EXPECTED. COOLER AND
SLIGHTLY MORE MOIST CONDITIONS ARE FORECAST FOR MONDAY BUT BREEZY
WINDS WILL CONTINUE. DMH

&&

.PIH WATCHES/WARNINGS/ADVISORIES...
RED FLAG WARNING FROM 2 PM THIS AFTERNOON TO 9 PM MDT THIS
EVENING FOR IDZ475-476.
