AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE POCATELLO ID
140 PM MDT THU JUN 23 2011

.DISCUSSION...UPPER TROUGH BEARING DOWN ON IDAHO PER WV SAT
IMAGERY THIS AFTERNOON WITH SOUTHWEST FLOW ALOFT OVER EASTERN
IDAHO. BAND OF MOISTURE MOVING INTO THE REGION PER SATELLITE BUT
GOOD LOW LEVEL MOISTURE IN PLACE WITH SURFACE DEWPOINTS RANGING
FROM THE 40S AT HIGHER ELEVATION TO THE LOWER AND MID 50S IN THE
SNAKE PLAIN...AMPLY MOIST FOR THIS REGION. ATMOSPHERE BEGINNING TO
DESTABILIZE WITH LAPS ANALYZED LIFTED INDICES IN THE -2 TO -4
RANGE AND CAPE OVER 1500J/KG ACROSS THE SNAKE PLAIN. A FEW WEAK
STORMS HAVE ALREADY FIRED AT THE LEADING EDGE OF THE MID LEVEL
MOISTURE AND SURFACE FRONT ACROSS THE CENTRAL MTNS WITH THE
REMAINING AREA QUIET FOR NOW. EXPECT STORMS TO DEVELOP ACROSS THE
REGION THIS AFTERNOON AND CONTINUE THROUGH THIS EVENING AHEAD OF
SURFACE FRONT. STRONGEST STORMS LIKELY TO STAY NORTH OF FCST AREA
BUT COULD SEE A FEW RATHER STRONG CELLS WITH DAMAGING WINDS AND
LARGE HAIL.

SURFACE FRONT AND UPPER TROUGH SHIFT NORTHEAST INTO CENTRAL AND
EASTERN MONTANA OVERNIGHT WITH CENTER OF UPPER LOW REMAINING AT
THE BC CANADA/ALBERTA BORDER. A LINGERING TAIL OF MOISTURE REMAINS
ACROSS THE REGION AND NAM IS VERY FAVORABLE IN CONTINUING
CONVECTION THROUGH THE DAY FRIDAY. HAVE NUDGED POPS UPWARD
SLIGHTLY. SFC GRADIENT TIGHTENS SOMEWHAT BEHIND FRONT AND WILL
ISSUE LAKE WIND ADVISORY FOR BREEZY CONDITIONS ACROSS AMERICAN
FALLS RESERVOIR. MODELS SHIFT UPPER LOW CENTER EAST BUT LEAVE
BASE OF TROUGH THROUGH MONTANA TOWARD EASTERN IDAHO WHILE UPPER
RIDGE TRIES TO BUILD ALONG COAST. CANNOT RULE OUT THE POSSIBILITY
OF ISOLATED THUNDERSTORMS EACH DAY THROUGH THE WEEKEND ESPECIALLY
OVER HIGHER TERRAIN. NEXT PACIFIC LOW CONTINUES TO DEVELOP OFF THE
PACNW COAST WITH BROAD RIDGE MOVING INTO THE NORTHERN ROCKIES FOR
MONDAY. SHOULD SEE CONDITIONS QUIET DOWN SOME EARLY NEXT WEEK BUT
THERE HAVE BEEN SOME DIFFERENCES IN THE EXTENDED MODEL RUNS. EARLY
LOOK AT 12Z ECMWF BRINGS SOLUTION IN LINE WITH 12Z GFS WHICH
STRENGTHENS SOUTHERLY FLOW ACROSS THE REGION BY TUESDAY AND HOLDS
STRONG UPPER LOW OFF NORTHERN CALIFORNIA COAST. THIS WOULD IMPLY A
DRIER SOLUTION FOR LATE IN THE EXTENDED PERIODS BUT GIVEN
UNCERTAINTY HAVE LEFT WEAK POPS JUST UNDER CLIMO FOR THE PERIOD. DMH

&&

.AVIATION...AN UPPER LEVEL LOW WAS SHIFTING EAST INTO CANADA THIS
AFTERNOON WITH A MOIST AND UNSTABLE SW FLOW OBSERVED ACROSS SRN
IDAHO. SCT-BKN CONVECTION IS EXPECTED ACROSS THE REGION THIS
AFTERNOON/EVE WITH GUSTY WINDS THROUGH 04Z. THE LOW SHIFTS EAST
INTO THE CANADIAN ROCKIES FRIDAY AFTERNOON WITH A SECOND ROUND OF
CONVECTION EXPECTED NEAR THE MONTANA/WYOMING BORDER. VFR
CONDITIONS ARE EXPECTED THROUGHOUT THE PERIOD. HUSTON

&&

.FIRE WEATHER...A STRONG LOW PRESSURE SYSTEM WAS OBSERVED MOVING
INTO WRN CANADA THIS AFTERNOON AND IS FORECAST TO MOVE SLOWLY EAST
THROUGH THE WEEKEND. WARM AND UNSTABLE CONDITIONS WILL PROMOTE
SCATTERED THUNDERSTORM ACTIVITY THIS AFTERNOON AND EVENING. COOLER
TEMPERATURES WILL FILTER INTO THE REGION TONIGHT AS THE LOW MOVES
SLOWLY EAST TOWARD THE CANADIAN ROCKIES. BREEZY CONDITIONS ARE
EXPECTED FRIDAY WITH INSTABILITY SHOWERS EXPECTED ALONG THE
MONTANA/WYOMING BORDER. A SECONDARY DISTURBANCE WILL DIG SE ALONG
THE DIVIDE SUNDAY AFTERNOON WHICH WILL LIKELY PROMOTE ANOTHER ROUND
OF CONVECTIVE ACTIVITY ALONG THE MONTANA/WYOMING BORDER. HUSTON

&&

.HYDROLOGY...HAVE CONTINUED FLOOD STAEMENT FOR HENRYS NEAR REXBURG
WITH CONTINUED HIGH FLOWS DUE TO SNOWMELT. OTHER RIVERS IN THE
REGION REMAIN HIGH BUT BELOW FLOOD CONCERN. TEMPERATURES FOR THE
NEXT WEEK EXPECTED TO REMAIN ONLY SLIGHTLY BELOW NORMAL SO
SNOWMELT SHOULD CONTINUE. PRECIPITATION THREATS AT THIS TIME
REMAIN CONVECTIVE AND NOT WIDESPREAD SO BASINS WILL LIKELY
EXPERIENCE HIT OR MISS RAINFALL TOTALS. GROUND IS SATURATED
ESPECIALLY AT HIGHER ELEVATIONS BUT BELIEVE STORMS WILL BE MOVING
QUICK ENOUGH SO FLASH FLOOD THREAT SHOULD BE MINIMIZED. DMH

.PIH WATCHES/WARNINGS/ADVISORIES...
LAKE WIND ADVISORY FROM 11 AM TO 9 PM MDT FRIDAY IDZ021.
