AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE POCATELLO ID
157 PM MDT MON MAY 25 2015

.SHORT TERM...TONIGHT THROUGH THURSDAY MORNING. AS ANOTHER CLOSED
UPPER LOW MOVES THRU THE PAC NW...SCATTERED SHOWERS AND TSTMS ARE
AGAIN DEVELOPING AS THE AIRMASS DESTABILIZES THIS AFTERNOON. THE
GREATEST COVERAGE WILL BE OVER THE MTNS. SMALL HAIL CAN BE
EXPECTED WITH SOME TSTMS. ACTIVITY WILL DIMINISH THIS EVE...BUT
PICK UP AGAIN TUE AFTN AND EVE AS THE UPPER LOW MOVES SLOWLY OVER
THE ID PANHANDLE. THE UPPER LOW REMAINS NEARLY STATIONARY INTO
THU...SO THE THREAT OF SHOWERS AND TSTMS WILL CONTINUE MAINLY
DURING THE AFTN AND EVE INTO THU. HEDGES

.LONG TERM...THURSDAY AFTERNOON THROUGH NEXT MONDAY. THE SLOW MOVING
LOW WILL FINALLY BE MOVING TO THE SOUTHEAST OF THE STATE AT THE END
OF THE WEEK. WE WILL STILL BE PRETTY STORMY ON THURSDAY WITH THE
STORM OVERHEAD. HIGH PRESSURE BEGINS TO BUILD IN BEHIND IT...BUT IT
STILL DOESN`T LOOK THAT DRY ACROSS THE AREA. FRIDAY AND SATURDAY
STILL HAS PLENTY  OF RESIDUAL MOISTURE FOR SHOWERS AND FEW STORMS
EXCEPT ACROSS THE MAGIC VALLEY AND SOUTH CENTRAL HIGHLANDS. THE
MODELS ARE NOW TRENDING TOWARD A WEAKER RIDGE AS A SYSTEM MOVES
ALONG THE US/CANADA BORDER AND KNOCKS IT DOWN QUICKLY. THIS KEEPS
SHOWERS AND STORMS GOING ESPECIALLY ACROSS THE NORTH. BY EARLY NEXT
WEEK...ANY RIDGE OVER IDAHO QUICKLY SHIFTS EAST AS THE NEXT STORMS
MOVES INLAND AND PUTS US UNDER SOUTHWEST FLOW. THIS WILL STREAM MORE
MOISTURE IN FOR YET MORE RAIN AND THUNDER. IT DOES THOUGH LOOK LIKE
WE WILL FINALLY WARM UP...WITH 80S FOR LOWER ELEVATIONS BY A WEEK
FROM NOW. KEYES

&&

.AVIATION...SHOWERS AND STORMS HAVE FIRED OFF AGAIN BUT COVERAGE SO
FAR HAS BEEN LESS TODAY. WE ARE CARRYING AT VCTS AT THE THREE VALLEY
TAF SITES...BUT -SHRA VCTS AT KSUN SINCE MOST OF THE ACTIVITY WILL
BE IN THE MOUNTAINS. AS USUAL...SMALL HAIL AND LOCALLY HEAVY RAIN IS
POSSIBLE AND DEFINITELY COULD AFFECT ANY OF OUR TAF SITES. BY THIS
EVENING...WE SHOULD SEE A BAND OF SHOWERS MOVING ACROSS WHICH
WARRANTS VCSH FOR THE OVERNIGHT HOURS AND TOMORROW MORNING. BY
AFTERNOON...YET ANOTHER ROUND OF THUNDERSTORMS IS LIKELY ESPECIALLY
ACROSS EASTERN AREAS MEANING KIDA AND KPIH MAY SEE A HIGHER
LIKELIHOOD. HOWEVER...ALL TAF SITES ARE IN LINE TO SEE SOMETHING.
EXPECT HAIL AND HEAVY RAIN...ALTHOUGH TOMORROW`S STORMS MAY HAVE A
BETTER POTENTIAL FOR GUSTY WINDS THAN THE PAST FEW DAYS. KEYES

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