AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE POCATELLO ID
328 AM MST SAT MAR 2 2013

.SHORT TERM...TODAY THROUGH MONDAY. LOW STRATUS AND PATCHY FOG IS
CONTINUING THIS MORNING OVER THE SNAKE RIVER PLAIN AND EASTERN
HIGHLANDS. LEFT FREEZING DRIZZLE IN AS IT CAN NOT BE RULED OUT...BUT
WILL VERY ISOLATED. LOOK FOR STRATUS TO CONTINUE UNTIL EARLY
AFTERNOON.

THE NEXT SYSTEM WILL ARRIVE LATE SATURDAY INTO SUNDAY. EXPECT
MODERATE TO STRONG WINDS WITH THIS SYSTEM SUNDAY PARTICULARLY IN
THE AFTERNOON. THE NAM12 MODEL HAS MOVED THE UPPER LEVEL LOW
NORTH OVER CANADA AND AS RESULT HAS LIGHTER WINDS ACROSS THE AREA.
THE GFS MODEL HAS LOWERED WINDS SPEEDS SLIGHTLY AS WELL. HAVE
LEFT THE HIGH WIND WATCH OUT FOR NOW. WILL WAIT FOR ANOTHER MODEL
RUN TO SEE IF THE MODELS SWITCH BACK TO HIGHER WIND SPEEDS. MOST
LIKELY JUST A WIND ADVISORY WILL BE NEEDED ACROSS THE EASTERN
MAGIC VALLEY AND SNAKE RIVER PLAIN WITH SUSTAINED WINDS SPEEDS 30
TO 39 MPH WITH GUSTS NEAR 45 TO 56 MPH. SNOW AMOUNTS WILL BE LESS
THAN A INCH ACROSS THE SNAKE RIVER PLAIN AND 3 TO 6 INCHES ACROSS
THE CENTRAL MOUNTAINS AND UPPER SNAKE HIGHLANDS. SLIGHTLY MORE
SNOW MAY BE POSSIBLE FOR THE UPPER SNAKE HIGHLANDS ACROSS HIGHER
ELEVATIONS. ALSO...EXPECT BLOWING AND DRIFTING SNOW ACROSS THE
AREA. WYATT

.LONG TERM...MON NIGHT THROUGH FRI NIGHT.  500MB 5-WAVE PATTERN IS
FOR A HIGH AMPLITUDE TROUGH JUST TO THE EAST OF THE FORECAST
AREA...KEEPING EASTERN IDAHO IN CYCLONIC FLOW AND IN THE STORM
TRACK.  THERE IS SOME SLIGHT RETROGRADE MOVEMENT ON WED.  AT THIS
SAME TIME...A VIGOROUS SHORTWAVE MOVES THROUGH...BRINGING
PRECIPITATION AS EARLY AS TUE NIGHT TO THE WESTERN ZONES...BUT
COVERING ALL AREAS BY WED NIGHT.  THE SPEED OF THE EXIT IS THE MOST
UNCERTAIN THING...WITH THE ECMWF MUCH SLOWER TO CLEAR.  ALSO...THE
ECMWF IS MUCH WETTER FOR THE TUE NIGHT TO THU PERIOD. THE LONGWAVE
PATTERN STARTS SHIFTING TOWARDS THE EAST IN A MORE NORMAL
PROGRESSION.  THE PATTERN ALSO DE-AMPLIFIES AND SO AFTER THIS MAIN
FEATURE OF THE PERIOD THE ECMWF AND GFS DIVERGE STRONGLY WITH THE
TRACK OF THE LOW ONCE IT IS EAST OF THE CONTINENTAL DIVIDE.  WITH
LARGE DIFFERENCES...ESPECIALLY TOWARDS THE END...HAVE TRIED TO GO
FOR THE MIDDLE WITH APPROXIMATE AVERAGES.  VERY LOW CONFIDENCE AFTER
THU.  MESSICK
