AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE POCATELLO ID
319 AM MDT TUE JUN 5 2012

.SHORT TERM...TODAY THROUGH THU NIGHT. FIRST BRUSH WITH STORM THAT
IS MOVING MORE SOUTH-NORTH THAN WEST-EAST WITH A STRONG OUTFLOW
BOUNDARY LAST NIGHT. THE GUST FRONT DID PUSH IN COLD TEMPERATURES
AND HIGH HUMIDITY ALONG WITH THE STRONG WIND THAT FIRST KICKED UP
A FIRE IN THE RAFT RIVER VALLEY...BUT THE MUCH HIGHER HUMIDITY
VERY NEARLY PUT IT OUT. THE LOW WILL TAKE ITS TIME TO AFFECT THE
EASTERN ZONES OF THE FORECAST AREA. HEAVIEST PRECIPITATION SHOULD
OCCUR TONIGHT. AIR ON THE WEST SIDE OF THE LOW IS COLD ENOUGH TO
GENERATE SNOW DOWN TO 6000 FEET IN THE CENTRAL IDAHO MOUNTAINS.
HOWEVER...IT IS NOW LOOKING AS IF WIDESPREAD ACCUMULATIONS BETWEEN
6000 AND 8500 FEET WILL BE AN INCH OR LESS...THEN HIGHER SNOW
ACCUMULATIONS ABOVE THAT ELEVATION. NAM AND GFS ARE FAR APART ON
HIGHS AND LOWS FOR MANY LOCATIONS...SO HAVE USED SREF GUIDANCE
WITH A FUDGE TOWARDS MOS OUTPUT AVERAGES BETWEEN THE TWO PRODUCT
SUITES. NAM CONTINUES TO BE THE MUCH COLDER AS IT KEEPS EVEN THE
POCATELLO AIRPORT BELOW 60 DEGREES. GFS HAS TRENDED COLDER BUT IS
9 DEG F WARMER IN ITS FORECAST. NEVERTHELESS...WE ARE CERTAINLY
NOT GOING TO BE TYING RECORDS FOR WARMTH AS WE DID YESTERDAY.
PRECIPITATION ENDS FROM SOUTH TO NORTH OVER THE FORECAST AREA ON
WED...AND BY WED NIGHT WE ARE BACK TO A FEW CLOUDS AND DRY
CONDITIONS. THU AND THU NIGHT APPEAR TO BE TRANQUIL UNDER DRY
SOUTHWESTERLY FLOW. THIS ALLOWS A STRONG WARMING...BUT STILL
COOLER THAN NORMAL ON AFTERNOON HIGHS FOR THIS PERIOD.

THIS BRINGS US TO THE MAIN FORECAST CONCERN...WHICH IS THE
OVERNIGHT LOW TEMPERATURES. FOR AGRICULTURAL AND HORTICULTURAL
INTERESTS...THE TEMPERATURES BOTH TONIGHT AND WED NIGHT WILL FLIRT
WITH THE FREEZING POINT. THIS WILL BE WIDESPREAD IN THE HIGHLANDS
AND CENTRAL IDAHO MOUNTAINS...WHERE AT LEAST SOME PLACES ARE USED
TO IT BEING BELOW FREEZING. HOWEVER...EVEN THOSE PLACES WILL BE
WELL BELOW FREEZING...SUCH AS STANLEY BEING SOLIDLY IN THE MIDDLE
20S AND EVEN SOME TEENS IN PLACES SUCH AS COPPER BASIN. FOR
TONIGHT...THE EASTERN MAGIC VALLEY IS THE MOST AT RISK AS THE
SKIES SHOULD CLEAR LATE TONIGHT AND WINDS CALM DOWN FIRST THERE.
ALTHOUGH BURLEY IS NOT EXPECTED TO GO BELOW FREEZING...AREAS IN
THE NORTHERN HALF OF THIS ZONE...SUCH AS CAREY AND SHOSHONE...ARE
MOST LIABLE TO REACH THE FREEZING MARK. WITH CLOUD COVER AND
PRECIPITATION STILL GOING ON IN THE EASTERN HALF OF THE FORECAST
AREA...DO NOT EXPECT FREEZING TEMPERATURES IN THAT AREA.
HOWEVER...ON WED NIGHT...WITH THE WIND FINISHED AND THE SKIES MUCH
CLEARER...AREAS NORTHWEST OF THE POCATELLO-BLACKFOOT-IDAHO FALLS
CORRIDOR...SUCH AS ABERDEEN...ATOMIC CITY...ROCKFORD...AND
MORELAND...WILL BE AT RISK OF SEEING TEMPERATURES SINK BELOW
FREEZING. THUS...HAVE ISSUED A FREEZE WATCH AT THIS TIME.

FINALLY...WIND IS BREEZY ENOUGH TODAY TO MAKE BOATING HAZARDOUS ON
THE AMERICAN FALLS RESERVOIR AND WILL BE ISSUING A LAKE WIND
ADVISORY FOR TODAY IN ADDITION TO THE FREEZE WATCHES.  MESSICK

.LONG TERM...FRI THROUGH TUE NIGHT. ANOTHER UPPER LEVEL LOW WILL
HAVE REACHED THE COAST BY FRI AND WILL SPREAD PRECIPITATION INTO
THE FORECAST AREA BY FRI AFTERNOON. BOTH THE ECMWF AND GFS
INDICATE ANOTHER TROUGH MOVING IN SAT. BOTH APPEAR EQUALLY
WET...ALTHOUGH THE TRACK OF THE STORM IS SLIGHTLY FARTHER NORTH
ON THE ECMWF. THUS AFTERNOON HIGH TEMPERATURES SHOULD PEAK ON FRI
WITH ANOTHER COOL DOWN ON A WET WEEKEND. WINDY CONDITIONS WITH
SHOWERS AND THUNDERSTORMS ARE EXPECTED FOR THEN. DRYING SHOULD
DEVELOP BY SUN AFTERNOON AND CONTINUE INTO THE FIRST TWO DAYS OF
THE WORK WEEK AT LEAST.  MESSICK

&&

.AVIATION...SHOWERS ARE LIKELY FOR THE MOUNTAINS AND HIGHLANDS
TODAY. LOW CEILINGS ARE LIKELY FOR ALL TAF SITES...BUT SHOULD REMAIN
VFR THROUGHOUT THE DAY. EXPECT GUSTY CONDITIONS TODAY AT SNAKE RIVER
TAF SITES.

VALLE

&&

.FIRE WEATHER...A STRONG COLD FRONT HAS MOVED THROUGH THE AREA.
EXPECT COOLER TEMPERATURES AND HIGHER RELATIVE HUMIDITIES THROUGHOUT
THE REGION TODAY. THERE IS A GOOD CHANCE FOR SHOWERS AND A FEW
THUNDERSTORMS...WITH THE BEST CHANCES IN THE MOUNTAINS AND
HIGHLANDS. GUSTY WINDS ARE ANTICIPATED...MAINLY IN THE SNAKE RIVER
PLAIN AND RIDGETOP LEVEL. DRY BUT COOL WEATHER IS EXPECTED FOR
WEDNESDAY AND THURSDAY DUE TO HIGH PRESSURE. BREEZY CONDITIONS WILL
PERSIST INTO WEDNESDAY BUT SHOULD DIMINISH FOR THURSDAY.

VALLE

.PIH WATCHES/WARNINGS/ADVISORIES...
