NATIONAL WEATHER SERVICE POCATELLO ID
226 AM MDT WED MAR 16 2011

.SHORT TERM...HAVE ADDED ZONE 23 TO SNOW ADVISORY WITH SNOW
CONTINUING INTO TONIGHT...THOUGH ONLY ABOVE 6500 FT LEVEL. RAN
WIND STUDY WHICH INDICATED STRONG 500MB...700MB AIRFLOW WERE
STRONG AND ACCOMPANIED BY 130KT-PLUS JET. WIND DIRECTION AT 700MB
LEFT ONLY ZONE 20 SO HAVE ONLY INCLUDED THE ONE ZONE...MAINLY OVER
THE ARCO DESERT. RAIN HAS ALREADY MOVED INTO MUCH OF THE AREA AND
TROUGH REMAINS OVER THE NORTHERN GREAT BASIN AND ROCKIES UNTIL
LATE TONIGHT WHEN IT EXITS TO THE EAST. HAVE BOOSTED POP AND CLOUD
COVER FOR TODAY AND FIRST HALF OF TONIGHT. WILL CONTINUE ALL OTHER
ADVISORIES FOR SNOW. A BRIEF BREAK IS POSSIBLE THU BUT LOW REMAINS
OFF COAST AND CONTINUES TO PUMP MOISTURE INTO NORTHERN
CA...OR...AND ID. POPS DROP OFF STRONGLY ON THU NIGHT AS WOUND UP
STORM APPROACHES COAST. CLOSED LOW TAKES ITS TIME AND ONLY LIGHT
PRECIPITATION EXPECTED THROUGH THE END OF THE PERIOD WITH LOW
STILL STRUGGLING TO MOVE ONSHORE EVEN BY SAT MORNING. COOLER
TEMPERATURES TODAY DUE TO CLOUD COVER...BUT FRONT PASSAGE DURING
THE EARLY EVENING THU NIGHT KEEPS COOLING TREND GOING UNTIL
SOUTHERLY FLOW RETURNS WITH APPROACH OF NEXT LOW ON FRI.  MESSICK

.LONG TERM...SATURDAY THROUGH WEDNESDAY. MODELS ARE IN MUCH
BETTER AGREEMENT...LEADING TO HIGHER CONFIDENCE IN THE EXTENDED
FORECAST.

BOTH MODELS SHOWING A LOW PRESSURE SYSTEM SITTING OFF OF THE COAST
OF WASHINGTON/OREGON ON SATURDAY. A SHORTWAVE TROUGH IS EXPECTED TO
EJECT FROM THE LOW AND MOVE THROUGH THE AREA ON SATURDAY. THIS WILL
PRODUCE A GOOD CHANCE OF PRECIPITATION THROUGH MUCH OF THE AREA.
HAVE TRIED TO TAPER CHANCES SOME TOWARDS THE UTAH BORDER AS THE GFS
SHOWS THAT MOST OF THE MOISTURE WILL REMAIN IN IDAHO.

A COUPLE MORE WAVES ARE EXPECTED TO SPIN OFF OF THE LOW AND ARRIVE
SUNDAY AND MONDAY RESPECTIVELY. HAVE INCREASED CHANCES BOTH DAYS. IF
MODELS REMAIN CONSISTENT...WILL LIKELY NEED TO INCREASE CHANCES MORE
ON BOTH DAYS...ESPECIALLY IN THE MOUNTAINS AND HIGHLANDS.

THE MODELS BEGIN TO DIVERGE ON TUESDAY. BEST GUESS IS THAT THE AREA
MAY HAVE A BRIEF TRANSITION TO ZONAL FLOW PRODUCING ISOLATED TO
SCATTERED SHOWERS.

VALLE

.AVIATION...WIDESPREAD PRECIPITATION WILL BE LIKELY ACROSS MUCH
OF THE AREA TODAY AS A COLD FRONT ARRIVES FROM THE WEST. THIS WILL
CREATE WIDESPREAD MVFR AND IFR CONDITIONS THROUGHOUT THE AREA.
GUSTY CONDITIONS WILL BE LIKELY OVER MUCH OF THE SNAKE PLAIN AS
WELL.

CONDITIONS MAY IMPROVE SOME TONIGHT AS THE COLD FRONT MOVES AWAY
FROM THE AREA AND PRECIPITATION BECOMES MORE SHOWERY AND GRADUALLY
MORE ISOLATED.
