AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE POCATELLO ID
326 AM MDT WED JUN 12 2013

.SHORT TERM...TODAY THROUGH FRI NIGHT. UPPER LEVEL TROUGH AND
SURFACE LOW MOVING THROUGH FROM SOUTH TO NORTH DURING THE DAY
TODAY. COUPLED WITH HIGHER PRECIPITABLE WATER AND MODERATE TO
STRONG CAPE...SPC HAS PUT THE NORTHEAST CORNER IN AN AREA OF
SLIGHT RISK OF SEVERE WEATHER TODAY AND TONIGHT. THIS AREA
INCLUDES IDAHO FALLS...REXBURG...DRIGGS...SWAN VALLEY...CLARK
COUNTY...AND FREMONT COUNTY. HAVE INCLUDED GUSTY DAMAGING WIND
WORDING IN FORECAST FOR THE APPROXIMATE AREA OUTLINED BY SPC. ON
THU...THE CLOSED UPPER LEVEL LOW WILL MOVE FROM THE PACIFIC COAST
INLAND AND REACH IDAHO THU NIGHT. THE CLOSE LOW BECOMES AN OPEN
WAVE IN ITS SOUTHERN EXTENT AND IS EXPECTED TO MOVE THROUGH THE
FORECAST AREA FRI. TEMPERATURES BEHIND THIS TROUGH COOL ENOUGH
WHERE ABOVE 8000 FT IN THE CENTRAL IDAHO MOUNTAINS THERE COULD BE
SOME SNOW. THE LOW APPROACHING TODAY WILL ACTUALLY KEEP A
NORTHERLY COMPONENT TO THE WIND ALL DAY AND INTO THE EVENING.
STRONGER WIND IS EXPECTED THU WITH THE STRONGER LOW...AND COULD BE
A BORDERLINE SITUATION FOR A LAKE WIND ADVISORY ON THU. THE
STRONGER TROUGH ON FRI WILL VERY LIKELY MEAN A LAKE WIND
ADVISORY...PERHAPS EVEN A WIND ADVISORY FOR THE SNAKE RIVER PLAIN.
ON FRI NIGHT...TRANSITION TO A CLEARER AND DRIER PATTERN DEVELOPS.

THE GFS AND THE NAM HAVE DIFFERENT SOLUTIONS WHEN IT COMES TO
TEMPERATURE. FOR THU...NAM IS MUCH COLDER WITH GREATER CLOUD COVER
AND COLDER INCOMING AIR. GFS IS WARMER...SOME 6 TO 12
DEG...DESPITE PRODUCING MUCH MORE PRECIPITATION FOR THU THAN THE
NAM. HAVE TRIED TO SPLIT THE DIFFERENCE. GFS THEN CATCHES UP ON
FRI OR IS EVEN COLDER...ESPECIALLY IN THE CENTRAL IDAHO MOUNTAINS.
THUS LOW CONFIDENCE IN TEMPERATURES. HOWEVER...IT IS THE LEAST OF
PROBLEMS WITH THE WIND EXPECTED AND THE POTENTIAL FOR SEVERE
WEATHER.  MESSICK

.LONG TERM...SAT THROUGH TUE NIGHT. TROUGH COMPLETES ITS EXIT AND
BY SAT EXPECTING WEAK UPPER LEVEL RIDGING AS ANOTHER INTENSE
CLOSED LOW SLIDES INTO THE EASTERN PACIFIC. SWITCH TO SOUTHERLY
WIND AND WARMER AIR MEANS AFTERNOON HIGHS GOING BACK ABOVE NORMAL.
THIS CLOSED LOW WILL MOVE ONTO THE WEST COAST AT THE VERY END OF
THIS EXTENDED PERIOD...BUT STILL LEAVES THE BULK OF THE FORECAST
AREA DRY DURING THE LAST 12 HOURS OF THIS FORECAST.  MESSICK

&&

.AVIATION...AN UPPER LOW OVER THE PAC NW WILL KEEP ID UNDER A SW
FLOW ALOFT. THIS WILL BRING MORE MOISTURE INTO THE REGION...
RESULTING IN SCT AFTN/EVE TSTMS. SOME TSTMS WILL PRODUCE GUSTY SFC
WINDS. TSTM COVERAGE WILL DIMINISH OVERNIGHT. VFR CIG/VIS EXPECTED
TO PREVAIL. HEDGES

&&

.FIRE WEATHER...AN UPPER LOW OVER THE PAC NW WILL RESULT IN
SCATTERED SHOWERS AND THUNDERSTORMS TODAY AND THURSDAY. SOME OF THE
THUNDERSTORMS MAY PRODUCE GUSTY WINDS. TEMPERATURES WILL CONTINUE TO
COOL THROUGH THE END OF THE WEEK. HEDGES
&&

.PIH WATCHES/WARNINGS/ADVISORIES...
NONE.
