VALLE

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE POCATELLO ID
248 AM MDT TUE APR 30 2013

.SHORT TERM...TODAY THROUGH THURSDAY NIGHT. ONE MORE WAVE WILL
MOVE ACROSS THE REGION TODAY. IT WILL BE COOLER TODAY WITH A
CHANCE OF SHOWERS GENERALLY ALONG AND NORTH OF A LINE FROM BANNER
SUMMIT TO GALENA SUMMIT THROUGH THIS EVENING. IT WILL BE A MIX OF
RAIN AND SNOW THROUGH EARLY EVENING...WITH ANYTHING AFTER BEING
ALL SNOW. SOUTH AND WEST OF THAT LINE IT WILL BE DRY AND QUITE
BREEZY...ALTHOUGH QUITE A BIT LESS COMPARED TO YESTERDAY'S EVENT.
WINDS WILL BE RIGHT AT THE LOW END OF WIND ADVISORY
CRITERIA. WITH THE RISK OF BLOWING DUST DUE TO DRY WEATHER AND
RECENT PLOWING...WE ARE ISSUING AN ADVISORY FOR AREAS JUST WEST OF
THE POCATELLO AIRPORT BACK THROUGH THE MAGIC VALLEY. WE ARE ALSO
INCLUDING PORTIONS OF THE SOUTH CENTRAL HIGHLANDS ESPECIALLY FROM
GENERALLY I-84 WESTWARD. WE WILL QUICKLY DRY OUT EXCEPT FOR SOME
LINGERING SHOWERS ALONG THE WYOMING BORDER. TONIGHT/EARLY
WEDNESDAY WILL BE COLD FOR PRETTY MUCH EVERYONE. THE MOUNTAINS
WILL BE IN THE SINGLE DIGITS AND TEENS WITH 20S TO NEAR FREEZING
FOR THE LOWER VALLEYS. THERE WILL BE SOME LINGERING WIND
OVERNIGHT...WHICH MAY BE ENOUGH TO KEEP SOME AREAS LIKE THE SNAKE
PLAIN FROM GETTING QUITE COLD. EVEN WITH ANY WIND...IT WILL BE AT
OR BELOW 32F AND WITH THE GROWING SEASON STARTING TOMORROW WE WILL
BE ISSUING A FREEZE WATCH FOR ALL OF THE SNAKE PLAIN AND MAGIC
VALLEY.

THE REST OF THE SHORT TERM WILL BE DRY AS WE WILL BE ON THE
EASTERN EDGE OF A BUILDING RIDGE. THIS WILL PLACE US UNDER
NORTHWEST FLOW. THIS WILL ACT TO SLOW THE PACE OF THE UPCOMING
WARMUP. WITH DRY AIR AND LIGHTER WINDS TOMORROW NIGHT...IT WILL BE
COLD ONCE AGAIN. THE TREND WILL BE IN MOUNTAINOUS AREAS FOR
TEMPERATURES TO WARM UP...WITH THE SNAKE PLAIN/MAGIC VALLEY
REMAINING THE SAME OR BEING COLDER WHEN YOU COMPARE IT TO TONIGHT.
THIS WILL LIKELY MEAN ANOTHER FREEZE EVENT...EVEN WHERE WE SHOULD
SEE SOME ELEVATED DRAINAGE WINDS ACROSS THE MAGIC VALLEY. AFTER
SITTING AROUND 10 DEGREES OR SO BELOW AVERAGE...HIGHS FOR THURSDAY
REBOUND TO 50S AND 60S FOR MOST OF US WHICH IS RIGHT AT
CLIMATOLOGY.  KEYES

.LONG TERM...FRIDAY THROUGH NEXT TUESDAY. GFS/ECMWF MODELS CONTINUE
TO SHOW AN UPPER RIDGE ALONG THE COAST EARLY IN THE PERIOD WITH A
SHORT-WAVE DISTURBANCE WORKING OVER THE RIDGE AND DROPPING SOUTH
THROUGH THE NRN ROCKIES FRIDAY/SATURDAY. DETAILS...TIMING AND TRACK
OF THIS PARTICULAR FEATURE SHOW CONSIDERABLE RUN TO RUN
INCONSISTENCY AMONG THE MODELS WITH THE ECMWF TRENDING FURTHER
WEST AND WETTER WHEREAS THE GFS IS TRENDING FURTHER EAST AND DRIER.
THUS WILL LEAVE CURRENT CHANCE/SLIGHT CHANCE MENTION OF
PRECIPITATION ALONE UNTIL THE MODELS SHOW BETTER AGREEMENT. FOR
SUNDAY...THE ECMWF HAS SHIFTED STRONGLY TOWARD THE GFS SOLUTION IN
PORTRAYING A CUT-OFF LOW DRIFTING AROUND THE GREAT BASIN. HAVE
NUDGED THE PRECIPITATION POTENTIAL UPWARDS SLIGHTLY WITH LITTLE
CONFIDENCE THAT THE MODELS WILL ACTUALLY GET THE PLACEMENT OF THE
LOW CORRECT THIS FAR OUT. BY MONDAY...FAIRLY SIGNIFICANT DIFFERENCES
ARISE BETWEEN THE MODELS AS THE GFS CONTINUES TO MAINTAIN A CUT-OFF
LOW OVER THE GREAT BASIN WHILE THE ECMWF FAVORS A SECOND PAC
DISTURBANCE TOPPING THE RIDGE AND DIGGING SE INTO/THROUGH THE NRN
ROCKIES. GENERALLY FAVOR THE ECMWF SOLUTION HERE ALTHOUGH CONFIDENCE
IS LOW CONCERNING EITHER SOLUTION. HUSTON

.AVIATION...UPPER TROUGH SHEARING SE THROUGH THE REGION TODAY/TONIGHT
TRIGGERING SCATTERED MAINLY MOUNTAIN SNOW SHOWERS...POTENTIALLY
IMPACTING KIDA AND KPIH WITH LOWER VFR CIGS IN TEMPORARY SHOWERS.
BREEZY WEST WINDS ANTICIPATED AT KBYI AND KPIH LATE THIS MORNING
THROUGH EARLY EVENING. HUSTON
