AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE POCATELLO ID
333 AM MDT SUN APR 28 2013

.SHORT TERM...INCOMING SHORT WAVE TODAY WILL INCREASE THE
WIND...AND A SECOND RE-INFORCING SHORTWAVE ON MON WILL CONTINUE
THE VERY WINDY CONDITIONS. LOCAL WIND STUDY INDICATES A WIND
ADVISORY TODAY FOR THE EASTERN MAGIC VALLEY AND THE LOWER SNAKE
RIVER PLAIN. ON MON...IT WILL SPREAD INTO THE UPPER SNAKE RIVER
PLAIN AND POSSIBLY SOME MOUNTAIN ZONES. BLOWING DUST MAY ALSO BE A
FACTOR AND WILL MAKE MENTION IN THE ADVISORY. A STRONG UPPER LEVEL
JET PLACED IN THE CORRECT LOCATION...STRONG 500MB WINDS...AND A
STRONG MSLP GRADIENT ALL CONTRIBUTE TO THE HIGH SCORE ON THE LOCAL
STUDY. WIND ADVISORY SHOULD BE OVER BETWEEN 29/00Z AND 29/03Z. THE
FACTORS ARE EVEN MORE FAVORABLE ON MON...AND WITH A SOUTHWESTERLY
GRADIENT...SPREAD INTO THE UPPER SNAKE RIVER PLAIN. STRONGER COLD
AIR ADVECTION AND STRONGER 700MB WINDS PUSH THE STUDY FORECAST TO
NEAR HIGH WIND WARNING. THE MAIN DIFFERENCE IS TIMING. THE MON
WIND EVENT WILL START LATER AND END LATER THAN TODAYS. THE COLDER
AIR WILL START DROPPING TEMPERATURES. HAVE SPLIT THE DIFFERENCE
BETWEEN A SLOWER COOLING GFS AND THE COLDER SCENARIO OF THE NAM.
EXPECT SOME HIGH ELEVATION SNOW...BUT NOT EXPECTING SIGNIFICANT
ACCUMULATION. CURRENT FORECAST KEEPS THE THREE DAY TOTAL TO LESS
THAN FIVE INCHES ANYWHERE...AND A PLACE LIKE STANLEY RECEIVING
LESS THAN HALF AN INCH.  MESSICK

.LONG TERM...WEDNESDAY THROUGH SUNDAY. WEDNESDAY SHOULD BE THE
COLDEST DAY OF THE WEEK BEHIND THE EXITING UPPER LEVEL TROF OF LOW

DRY CONDITIONS THURSDAY THROUGH SATURDAY WITH TEMPERATURES ABOVE
NORMAL BY LATE NEXT WEEK INTO THE WEEKEND. A WEEK DISTURBANCE IN

SHOWERS AND EVEN A THUNDERSTORM...BUT TIMING MAY BE OFF A LITTLE
SO WILL ONLY PLACE SOME RAIN SHOWERS OVER THE MOUNTAINS AT THIS
POINT. PRESTON
