AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE POCATELLO ID
306 AM MDT WED JUN 10 2015

.SHORT TERM...TODAY AND THURSDAY. WE ARE STILL ON TAP FOR A WET
AND STORMY DAY ACROSS EASTERN IDAHO. LINGERING SHOWERS AND STORMS
REMAIN OVER THE CENTRAL MOUNTAINS EARLY THIS MORNING. WITH
MOISTURE STILL ON THE INCREASE...THE THREAT FOR HEAVY RAINFALL AND
POTENTIAL FLOODING IS A LITTLE MORE WIDESPREAD TODAY. THE FORECAST
WILL BE COMPLEX THOUGH. THE HIGHEST CHANCES WILL BE IN THE
CENTRAL MOUNTAINS AND UPPER SNAKE HIGHLANDS FOR MOST OF
TODAY...AND THE HIGHEST LIKELIHOOD OF HEAVY RAINFALL. OTHER AREAS
WILL SEE A LOWER CHANCE OF STORMS BUT THAT DOESN'T MEAN THOSE
AREAS WON'T SEE HIGHER RAINFALL AMOUNTS. IT MAY TAKE A LITTLE MORE
FOR THAT TO HAPPEN THOUGH...SUCH AS STATIONARY OR MULTIPLE STORMS
MOVING OVER A PARTICULAR LOCATION. THE OVERALL THEME THROUGH THIS
EVENING NEEDS TO BE THIS...BE MINDFUL THAT STORMS MAY DEVELOP OVER
YOUR AREA AND THE THREAT OF HEAVY RAINFALL IS THERE EVEN IF YOUR
CHANCE OF RAIN IS 20 PERCENT VS 60 PERCENT. WE SHOULD SEE SOME
SMALL HAIL AND EVEN A SMALL SHOT AT GUSTY WINDS WITH STRONGER
STORMS. AS THE LOW SLOWLY MOVES TO OUR EAST IN THE NEXT 36
HOURS...THE MAIN FOCUS FOR SHOWERS AND STORMS WILL SHIFT FAIRLY
QUICKLY TOWARD THE SOUTHERN AND EASTERN HIGHLANDS. THERE MAY BE
SOME SHOWERS/STORMS REDEVELOP OVER PORTIONS OF THE CENTRAL
MOUNTAINS TOMORROW BUT THE CHANCE IS SMALL. TEMPERATURES WILL BE A
FEW DEGREES COOLER BUT STILL AT OR JUST ABOVE AVERAGE FOR EARLY
JUNE. KEYES

.LONG TERM...THURSDAY NIGHT THROUGH NEXT WEDNESDAY. AS WE ROUND
OUT THE WEEK...OUR FLOW BECOMES WESTERLY AGAIN AS LOW PRESSURE
DEVELOPS OVER SOUTHERN CANADA AND SETTLES SOUTHWARD A BIT. WE
SHOULD BE MOSTLY DRY ON FRIDAY...EXCEPT FOR SOME SHOWERS/STORMS
REDEVELOPING FROM MACKAY TO ISLAND PARK AND SOUTH FROM THERE
CLOSER TO THE WYOMING BORDER. IT WILL BE A BIT MORE BREEZY WITH
HIGHS IN THE 80S FOR THE VALLEYS AND 60S/70S FOR THE HIGH COUNTRY.
THE MODELS HAVE SOME DIFFERENT IDEAS ON HOW TO HANDLE SOME OF THE
FINER FORECAST POINTS FOR THE WEEKEND AND NEXT WEEK. THEY BOTH DO
SHOW SOME SEMBLANCE OF WEST OR SOUTHWEST FLOW NEXT WITH THE
OCCASIONAL UPTICK IN DEVELOPING SHOWERS AND STORMS. IT IS JUST A
MATTER OF TIMING THE INDIVIDUAL STORMS EMBEDDED IN THE PATTERN AND
HOW FAR NORTH OR SOUTH THE MOVE ACROSS THE WESTERN US AND CANADA.
WE WILL LIKELY BE A BIT COOLER AS THE PATTERN IS MORE FROM THE
PACIFIC BUT STILL PRETTY CLOSE TO EARLY-MID JUNE AVERAGES. KEYES

&&

.AVIATION...A WEAK COLD FRONT WILL MOVE THROUGH THE AREA TODAY. THIS
WILL PRODUCE A FEW THUNDERSTORMS WHICH COULD AFFECT TAF SITES THIS
AFTERNOON. OTHERWISE WINDS WILL REMAIN RELATIVELY LIGHT EXCEPT NEAR
STORMS AND CONDITIONS WILL REMAIN VFR.

VALLE

&&

.FIRE WEATHER...A COLD FRONT WILL MOVE THROUGH THE AREA TODAY. THIS
WILL PRODUCE A GOOD CHANCE FOR SHOWERS AND THUNDERSTORMS TODAY. MOST
OF THE AREA WILL EXPERIENCE DRY WEATHER THURSDAY AND FRIDAY. SHOWERS
AND THUNDERSTORMS WILL REMAIN POSSIBLE ON THURSDAY ACROSS EXTREME
SOUTHEAST IDAHO AS LOW PRESSURE MOVES THROUGH UTAH.

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