AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE POCATELLO ID
1257 PM MDT MON SEP 8 2014

.DISCUSSION...THE UPPER TROF DIGGING INTO NORTHERN CA TODAY IS
FORCING THE RIDGE TO BUILD OVER THE GREAT BASIN. THIS IS ALLOWING
THE FLOW OF TROPICAL MOISTURE INTO SOUTHERN ID. SHOWERS AND A FEW
TSTMS ARE EXPECTED THIS AFTN AND EVE OVER MAINLY THE SOUTHERN AND
EASTERN HIGHLANDS AND THE ADJACENT SNAKE RIVER PLAIN. ISOLATED
SHOWERS/TSTMS ARE ALSO POSSIBLE NEAR THE DIVIDE. ACTIVITY RETREATS
TO THE SE CORNER OF ID OVERNIGHT. A DRY COLD FRONT IS EXPECTED TO
MOVE THRU ID ON TUE...AS THE NORTHERN STREAM SAGS SOUTHWARD INTO
NORTHERN ID. THIS WILL PUSH THE TROPICAL MOISTURE OUT OF THE AREA
AS WELL AS BRINGING GUSTY WEST WINDS AND COOLER TEMPS. SHOWERS ARE
POSSIBLE IN THE EASTERN HIGHLANDS AND ALONG THE DIVIDE WHERE THE
STRONGER UPPER FLOW INTERACTS WITH THE TERRAIN. THE REST OF THE
PERIOD LOOKS DRY EXCEPT FOR A FEW SHOWERS ALONG THE DIVIDE DUE TO
THE FLOW INTERACTING WITH THE TERRAIN. ANOTHER SHOT OF COOLER AIR
WILL COME ON THU AS A BACK DOOR COLD FRONT SPILLS OVER THE DIVIDE
FROM A CANADIAN HIGH MOVING INTO MT AND WY. TEMPS BEGIN TO WARM
OVER THE WEEKEND AS UPPER RIDGING BUILDS BACK INTO THE WEST.

.AVIATION...MOISTURE CONTINUES TO WORK ACROSS EASTERN IDAHO TODAY
AHEAD OF TOMORROW'S PASSING COLD FRONT. WE HAVE INCLUDED VCTS OR
VCSH AT ALL TAF SITE THROUGH THIS EVENING. STRONGER ACTIVITY MAY
PRODUCE SMALL AND WINDS OVER 40KTS ALONG WITH BRIEF HEAVY RAIN. AS
MOISTURE BEGINS TO GET PUSHED TOWARD OUR FAR EASTERN AREAS...WE
SHOULD VCSH/VCTS END EXCEPT AT KPIH AND POSSIBLY KIDA OVERNIGHT. THE
FRONT SWINGS THROUGH TOMORROW...WITH STRONG WINDS BEHIND IT. WINDS
OF 20-25KT SUSTAINED ARE LIKELY AT ALL 3 VALLEY SITES. WE WILL HAVE
TO WATCH FOR OCCASIONAL SWITCHES FROM SOUTH TO WEST WINDS IN THIS
PATTERN AT KSUN...AS SOMETIMES THE WINDS BECOME DOMINANT THROUGH
CANYONS TO THE WEST OF THE AIRPORT VS. UP THE WOOD RIVER VALLEY.
KEYES

&&

.FIRE WEATHER...SHOWERS AND ISOLATED/WIDELY SCATTERED STORMS WILL BE
POSSIBLE THROUGH THIS EVENING AS MOISTURE STREAMS NORTHEAST AHEAD
OF TOMORROW'S PASSING COLD FRONT. MOST THIS WILL BE OCCURRING
ALONG/SOUTH OF THE SNAKE RIVER...WITH A FEW STORMS POSSIBLE ACROSS
THE CENTRAL MOUNTAINS AND TOWARD MONIDA PASS. STRONG WINDS OVER
45MPH...SMALL HAIL AND BRIEF HEAVY RAIN ARE EXPECTED. FOR OVERNIGHT
AND TUESDAY...DRIER AIR WORKS INTO THE AREA AND PUSHES ANY
PRECIPITATION CHANCES TO NEAR ISLAND PARK SOUTH TOWARD BEAR LAKE IN
THE MOUNTAINS. MEANWHILE...WINDS PICK UP DURING THE DAY WITH
10-20MPH SUSTAINED WINDS POSSIBLE FOR MANY AREAS WITH GUSTS OF
20-30MPH. FOR THE SNAKE PLAIN AND MAGIC VALLEY...WINDS UP TO 30MPH
AND GUSTS TO 40MPH ARE LIKELY. HUMIDITY VALUES WILL DROP TO THE
10-15 PERCENT RANGE FOR MANY OF THE CENTRAL MOUNTAIN VALLEYS AND ALL
OF THE SNAKE PLAIN/MAGIC VALLEY. SINCE FUELS ARE NOT CRITICAL..WE
WILL NOT BE ISSUING ANY RED FLAG WARNINGS THIS TIME AROUND. COOLER
NORTHWEST FLOW WILL TAKE OVER BEHIND THE FRONT. INITIALLY WE WILL
SEE HIGHER HUMIDITIES THROUGH THE END OF THE WEEK...AND POSSIBLE
SHOWERS ALONG THE DIVIDE. THE WINDS WILL BE BREEZY THROUGH THURSDAY
BUT NOT NEARLY AS STRONG AS TOMORROW. AFTER THAT...DRY WEATHER
CONTINUES AS HIGH PRESSURE BUILDS OVER THE REGION.  KEYES
