AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE POCATELLO ID
225 PM MDT SUN SEP 4 2011

.DISCUSSION...

MONSOONAL MOISTURE HAS MADE IT AS FAR NORTH AS CENTRAL NEVADA AND
CENTRAL UTAH THIS AFTERNOON. THIS MOISTURE SHOULD ARRIVE IN IDAHO
ON MONDAY. THIS PUSH OF MOISTURE IS NOT AS SIGNIFICANT AS OTHER
BATCHES THE AREA HAS SEEN THIS YEAR. SO...THUNDERSTORMS EXPECTED
TO REMAIN ISOLATED MONDAY AND TUESDAY.

SLIGHTLY DRIER AIR WILL ARRIVE ON WEDNESDAY BEHIND A WEAK
SHORTWAVE TROUGH. ALTHOUGH MOST OF THE MOISTURE WILL HAVE PUSHED
EAST OF THE REGION...ENOUGH MOISTURE WILL REMAIN OVER THE AREA TO
PRODUCE SOME SLIGHT CHANCES FOR THUNDERSTORMS FOR THE REMAINDER OF
THE WEEK.

VALLE

&&

.AVIATION...UPPER RIDGE OVER THE REGION WILL MAINTAIN SKC/VFR
CONDITIONS ACROSS THE REGION THROUGH MONDAY AFTERNOON. MESSICK

&&

.FIRE WEATHER...HAINES INDEX WILL RISE TO SIX OVER THE
SALMON-CHALLIS NF AREA BY MON.  WITH ONGOING FIRES...HAVE DECIDED TO
ISSUE RED FLAG WARNING FOR THE AFFECTED AREA...GOOD FOR ALL DAY.
OTHERWISE...UPPER LEVEL RIDGE IS STAYING STRONG AND KEEPING MOISTURE
OUT OF AREA UNTIL LATE MON AFTERNOON AND EARLY MON EVENING.  WEAK
LOW PRESSURE MOVING ACROSS THE SOUTHERN BORDER REGION OF IDAHO WILL
SPREADING MAINLY HIGH CLOUDINESS MON AFTERNOON AND FINALLY DEVELOP
SOME NOCTURNAL SHOWERS AND THUNDERSTORMS MAINLY IN AREAS SOUTH OF A
KETCHUM-IDAHO FALLS LINE. BY TUE...THE PRECIPITATION/THUNDERSTORM
PATTERN WILL BE ORIENTED MORE NORTH-SOUTH AND MAINLY EAST OF
ARCO-BURLEY.  THE LOW MAKES A FAST EXIT DURING THE DAY TUE AND THE
HIGH RETURNS OVERNIGHT TUE NIGHT.  WEAK TROUGHING OFF THE CALIFORNIA
COAST MAKES THE SECOND HALF OF THE FORECAST LOW IN CONFIDENCE.
CURRENTLY...IT APPEARS THAT BY FRI THIS LOW WILL HAVE MOVED ONSHORE
ENOUGH TO SHIFT THE FLOW FROM THE DRY WESTERLIES TO SOUTHERLY FLOW.
THIS WILL OPEN THE DOOR TO MOIST UNSTABLE AIR ADVECTING NORTHWARD
AND THE BIGGEST THREAT OF THUNDERSTORMS AND PRECIPITATION FOR THE
WEEK APPEARS TO BE SAT AND SUN.  VERY LITTLE IN THE WAY OF WIND.
THE HUMIDITY WILL RISE STRONGLY IN THE HIGHER ELEVATIONS ON MON
NIGHT FOR SOME BETTER RECOVERY...RATHER THAN THE POOR RECOVERY WE
HAVE EXPERIENCED LATELY.  STILL MOST LOCATIONS...ESPECIALLY CENTRAL
IDAHO...WILL STILL SEE AFTERNOON HUMIDITY AT 20 PERCENT OR BELOW.
