AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE POCATELLO ID
217 PM MDT FRI APR 1 2011

.SHORT TERM...TONIGHT THROUGH MONDAY. UPPER RIDGE IN PLACE TODAY
WITH MAINLY HIGH CLOUDS MOST AREAS. BIG CHANGE COMING AGAIN FOR
SATURDAY WITH STRONG PACIFIC TROUGH MOVING THROUGH THE REGION.
SURFACE COLD FRONT POISED TO PASS THROUGH DURING THE AFTERNOON
HOURS. AIRMASS AHEAD OF THE FRONT QUITE WARM. BOTH NAM AND GFS
PAINT WEAK INSTABILITY ACROSS EASTERN HALF OF THE FORECAST
AREA...ENOUGH TO WARRANT CONTINUATION OF SLIGHT CHANCE
THUNDERSTORMS. VERY STRONG TEMP AND PRESSURE GRADIENT BEHIND THE
FRONT INDICATES POTENTIAL FOR VERY STRONG WINDS ACROSS THE REGION.
250MB JET DIRECTLY OVERHEAD WITH FAVORABLE POSITIONING OF SURFACE
LOW AND GOOD MID LEVEL SUPPORT. ALL GUIDANCE POINTING TO HIGH
CONFIDENCE OF AT LEAST 30 MPH WINDS THROUGH MUCH OF THE SNAKE
PLAIN BUT SOME INDICATION THAT PORTIONS OF THE REGION WILL SEE 40
MPH OR GREATER SUSTAINED. WILL OPEN WITH A WIND ADVISORY FOR 18Z
TO 03Z DURING THE BEST TIME FOR STRONG WINDS...AND LEAVE TO
FOLLOWING SHIFTS TO UPGRADE SOME OR ALL TO HIGH WIND WARNING IF
NECESSARY. SYSTEM DOES MOVE THROUGH FAIRLY QUICKLY SO SNOW AMOUNTS
NOT REALLY A CONCERN ESPECIALLY GIVEN HIGH SNOW LEVELS TO START.
AIRMASS DOES COOL OFF ENOUGH TO KEEP SNOW LEVELS VERY CLOSE TO
VALLEY FLOORS INTO SUNDAY BUT PRECIP FOCUS MAY ONLY LINGER IN THE
HIGHER ELEVATIONS UNTIL UPPER TROUGH AXIS FINALLY PASSES THROUGH
THE REGION MIDDAY SUNDAY. REMAINDER OF THE SHORT TERM DOMINATED BY
COOL NORTHWEST FLOW WHICH WILL KEEP TEMPS BLOW NORMAL BUT
CONDITIONS SHOULD STAY RELATIVELY DRY. DMH

.LONG TERM...MONDAY NIGHT THROUGH NEXT FRIDAY. THE MODELS CONTINUE
TO SHOW LARGE VARIATIONS ON RESOLVING THE PATTERN FOR THE MIDDLE AND
END OF NEXT WEEK. FOR TUESDAY...THERE MIGHT BE SOME GOOD AGREEMENT
ON MORE FLAT AND ZONAL FLOW FOR THE STATE...PUTTING SOME CHANCE OF
RAIN/HIGH MOUNTAIN SNOW MAINLY ACROSS THE CENTRAL MOUNTAINS AND
UPPER SNAKE HIGHLANDS. IT WILL ALSO BREEZY ACROSS EASTERN IDAHO AS
WELL FOR THAT DAY. BEYOND THAT...HAVE PRETTY MUCH KEPT THE FORECAST
THE SAME AS PREVIOUS SHIFTS WITH SOME RAIN AND SNOW IN THE
PICTURE...RIGHT AROUND CLIMATOLOGY FOR EARLY APRIL. TEMPERATURES
LEANED TOWARD THE ECMWF WHICH WAS COOLER THAN THE GFS DUE TO THE
SYSTEM BEING MORE ON TOP OF US VERSUS ALONG THE WEST COAST.  KEYES

&&

.AVIATION...VFR CONDITIONS WILL PREVAIL THROUGH MOST OF TONIGHT. ON
SATURDAY...A SYSTEM WILL MOVE NORTHWEST TO SOUTHEAST ACROSS THE
AREA. WE WILL SEE GUSTY SOUTHERLY WINDS AHEAD OF IT...SWITCHING TO
VERY STRONG WESTERLY WINDS BEHIND IT WE COULD EASILY SUSTAINED WINDS
IN EXCESS OF 30 KTS. AS THE SYSTEM MOVES THROUGH...SHOWERS AND
AFTERNOON THUNDERSTORMS ARE LIKELY ACROSS THE AREA. CEILINGS WILL
LOWER BUT SHOULD REMAIN VFR UNLESS YOU ARE UNDER HEAVIER
PRECIPITATION THAT WOULD DROP THINGS INTO LIKELY MVFR. WITH STRONGER
STORMS TOMORROW...WE COULD SEE VERY STRONG WIND GUSTS AT TIMES. KEYES
