AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE POCATELLO ID
253 AM MDT MON APR 14 2014

.SHORT TERM...TODAY THROUGH WEDNESDAY NIGHT. HIGH PRESSURE THROUGH
TONIGHT...ALTHOUGH THE RIDGE BEGINS TO FLATTEN OUT AS IT MOVES THE
STATE. THERE WILL BE A SLOW INCREASE IN HIGHER CLOUDS AS
WELL...WHICH MAY PROVE TO BE A POTENTIAL ISSUE FOR THOSE VIEWING
THE LUNAR ECLIPSE. IT SHOULDN`T BE A TOTAL BUST AT THIS POINT
THOUGH. DUE TO DRY AIR IN PLACE...IT WILL BE A COLD ONE FOR A
WHILE THIS MORNING. HOWEVER...THE DRY AIR WILL ALLOW FOR A DECENT
REBOUND IN TEMPERATURES THIS AFTERNOON. WE WILL BE RUNNING RIGHT
AROUND NORMAL FOR MID APRIL AND 5-10 DEGREES WARMER THAN SUNDAY.

TUESDAY AND WEDNESDAY WILL BRING A RETURN TO ACTIVE WEATHER ACROSS
EASTERN IDAHO. A COLD FRONT WILL SWING ACROSS OUR AREA TOMORROW
AFTERNOON. BREEZY SOUTHERLY WINDS WILL GIVE WAY TO WEST TO
NORTHWEST WINDS DURING THE DAY. WE WILL ALSO SEE SHOWERS AND
POTENTIAL THUNDERSTORM DEVELOPING MAINLY ACROSS THE CENTRAL AND
EASTERN MOUNTAINS. WE MAY SEE A BIT OF ACTIVITY ACROSS THE SOUTH
AND EVEN WITH THE FRONT...BUT THE POTENTIAL IN THOSE AREAS WILL BE
PRETTY LIMITED. THE BIGGER CONCERN WILL BE THE WINDS ESPECIALLY
ACROSS PORTIONS OF THE SNAKE PLAIN...MAGIC VALLEY AND PORTIONS OF
THE SOUTH CENTRAL HIGHLANDS. THE UPPER PLAIN APPEARS TO MISS OUT
ON THE STRONGEST WINDS FOR THE MOST PART. THERE MAY BE A BRIEF
PERIOD OF STRONGER WINDS WITH THE FRONT BUT OTHER THAN
THAT...IMPACTS RELATED TO WIND WILL BE PRETTY LOW THERE INCLUDING
BLOWING DUST. WE ARE LOOKING A LIKELY LOW-END WIND ADVISORY EVENT
FOR THOSE AREAS LISTED ABOVE. IF IT`S LIKE PREVIOUS
EVENTS...BLOWING DUST MAY END UP BEING MORE LOCALIZED AND NOT MUCH
OF AN IMPACT OVERALL. THAT WILL NEED TO BE MONITORED THOUGH. AS
THE STORM PASSES...IT APPEARS THAT A CONVERGENCE EVENT WILL DROP
SOUTHWARD ACROSS THE SNAKE PLAIN IN ADDITION TO A BAND ACROSS THE
EASTERN HIGHLANDS TOMORROW NIGHT. THE CONVERGENCE BAND SHOULDN`T
MAKE ANY FARTHER SOUTHWEST THAN A CRATERS TO POCATELLO LINE.
OVERALL PRECIPITATION AMOUNTS WILL BE LIGHT...WITH SNOW LEVELS
DROPPING TO 4500-5300 FEET BY WEDNESDAY MORNING. AS THE TAIL END
OF A STORM ACROSS THE NORTHERN PLAINS SWINGS SOUTH INTO
MONTANA...THIS WILL HELP KEEP SHOWERS GOING AREAWIDE ON WEDNESDAY
WITH HIGHER CHANCES CLOSER TO THE MONTANA BORDER AND DIVIDE AREAS.
TEMPERATURES WILL BE ABOUT 5 DEGREES COOLER ACROSS THE CENTRAL
MOUNTAINS TOMORROW...AND ABOUT 5 DEGREES WARMER ACROSS EASTERN
AREAS DUE TO THE FRONT ARRIVING LATER IN THE DAY. BY
WEDNESDAY...WE WILL BE RUNNING 5 DEGREES OR SO BELOW NORMAL AND
3-8 DEGREES COOLER THAN TUESDAY.  KEYES

.LONG TERM...THURSDAY THROUGH MONDAY.

SYSTEM PULLS AWAY FROM THE AREA ON THURSDAY WITH JUST A FEW ISOLATED
SHOWERS POSSIBLE IN THE EASTERN HIGHLANDS. TRANSITORY RIDGE WILL
BRING DRY WEATHER TO THE AREA FOR FRIDAY. A WEAK SYSTEM WILL ARRIVE
FRIDAY NIGHT AND SATURDAY. LOOKS LIKE A FEW ISOLATED TO SCATTERED
SHOWERS POSSIBLE DURING THIS TIME BUT NOTHING SIGNIFICANT. DRY AND
WARM WEATHER RETURNS FOR SUNDAY AS A RIDGE SLIDES THROUGH THE AREA.
PERHAPS ANOTHER SYSTEM ARRIVES FOR EARLY NEXT WEEK BRINGING
SCATTERED SHOWERS TO THE AREA.
