AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE POCATELLO ID
848 PM MDT SUN APR 1 2007

.SHORT TERM...KSFX 88D SHOWING WIDESPREAD BATCH OF LIGHT
PRECIPITATION OVER EASTERN IDAHO...WITH ANOTHER BATCH UPSTREAM.
CURRENT POP/WX GRIDS HAVE THIS WELL IN HAND SO NO UPDATES NEEDED FOR
PRECIP TONIGHT. 00Z NAM RUN HAS COME IN...AND GIVEN STRENGTH OF
WINDS HAVE BEEN SOMEWHAT UNDERPLAYED LAST COUPLE DAYS AM CONCERNED
FOR WIND FORECAST FOR MON. UPPER PATTERN IS NOT IDEAL FOR STRONG
WINDS...ESPECIALLY GIVEN STRONG GRADIENT IN MID-LEVELS AND EXPECTED
POSITION OF UPPER JET ALONG SOUTHERN BORDER. HOWEVER...NAM CONTINUES
TO ADVERTISE 110KT JET ALONG WITH 70KT 500MB WINDS ALONG SOUTHERN
HIGHLANDS. CURRENT NAM NUMERICAL GUIDANCE NOT IN YET BUT FWC
GUIDANCE BRINGS WINDS VERY CLOSE TO ADVISORY CRITERIA. LOCAL WIND
STUDY RUN ON 00Z NAM ALSO SHOWS A MORE FAVORABLE SCORE FOR HIGH
WINDS. WILL UPDATE GRID PACKAGE TONIGHT TO INCLUDE WIND ADVISORY FOR
SNAKE RIVER VALLEY ZONES FOR MON.

UPPER LOW STILL PROGGED TO SLIP EAST MONDAY NIGHT WITH DRY NORTHWEST
FLOW AND A RELAXED GRADIENT MON NIGHT THROUGH TUESDAY. SOME CLOUD
COVER MOVING THROUGH SHORT WAVE BUILDING RIDGE TUESDAY. MINOR
DISTURBANCE TRICKLES THROUGH THIS FLOW PATTERN BUT DOUBT IT WILL
GENERATE SHOWERS. RS/DMH

.LONG TERM...WEDNESDAY THROUGH SUNDAY. A RIDGE OF HIGH PRESSURE WILL
BUILD OVER THE INTERMOUNTAIN REGION DURING THE EXTENDED PERIOD. THIS
WILL LEAD TO DRY CONDITIONS AND WARMING...WITH TEMPERATURES INTO THE
MID TO UPPER 60S IN VALLEY LOCATIONS LIKELY BY THE END OF THE WEEK.
FORECAST MODELS ARE INDICATING TWO DISTURBANCES THAT ARE EXPECTED TO
PASS THROUGH THE RIDGE. THE FIRST OCCURRING WEDNESDAY AND THE NEXT
SATURDAY. EACH OF THESE DISTURBANCES LACK SUBSTANTIAL MOISTURE...AND
WITH A RIDGE IN PLACE...IT WILL BE DIFFICULT FOR THEM TO GENERATE
ANYTHING SUBSTANTIAL IN THE FORM OF PRECIPITATION. THUS...HAVE DRIED
OUT MUCH OF THE EXTENDED PERIOD WITH THE LATEST FORECAST. CANTIN

&&

.AVIATION...EASTERN IDAHO WILL REMAIN UNDER THE INFLUENCE OF ZONAL
FLOW THROUGH THE EVENING...THEN AN UPPER-LEVEL DISTURBANCE WILL
CROSS OVER THE AREA OVERNIGHT. VFR CONDITIONS WILL BE THE RULE AHEAD
OF THIS DISTURBANCE...THEN BY 04Z MID AND LOW LEVEL MOISTURE WILL
INCREASE ENOUGH TO GENERATE POCKETS OF MVFR/IFR CONDITIONS. THIS
WILL GENERALLY OCCUR ALONG MOUNTAINOUS PORTIONS OF TWEB ROUTES...AND
FOR A BRIEF PERIOD AT KIDA AND KPIH. WINDS WILL CAUSE THE BIGGEST
IMPACT...WITH AFTERNOON WINDS MONDAY APPROACHING OR EXCEEDING 25KTS
SUSTAINED AT KBYI...KPIH...AND KIDA. CANTIN
