AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE POCATELLO ID
129 PM MDT SAT JUL 14 2012

.DISCUSSION...SAT IMAGERY SHOWS WRAPPED UPPER LOW OVER NORTHWEST
OREGON THIS MORNING ALONG WITH DEEP SOUTHERLY FLOW THROUGH THE GREAT
BASIN AND ANOTHER LOW ROTATING NORTH ALONG THE NEVADA/UTAH BORDER.
AMPLE MOISTURE KEEPING CLOUD COVER ACROSS MUCH OF EASTERN IDAHO
WHICH HAS HELPED TO LIMIT TEMPS AND INSTABILITY FOR TODAY. ROUND OF
STRONGER CONVECTION ASSOCIATED WITH GREAT BASIN LOW BEGINNING TO
MOVE INTO SOUTHERN IDAHO. BETTER INSTABILITY EXISTS OVER CENTRAL
MOUNTAINS BUT HIGH LEVEL BLOW OFF FROM SOUTHERN CONVECTION MAY LIMIT
POTENTIAL DEVELOPMENT ACROSS THE CENTRAL MOUNTAINS. WILL CONTINUE
CHANCE OR BETTER POPS FOR TONIGHT ACROSS THE REGION. MOST CELLS
SHOULD BE CAPABLE OF PRODUCING WETTING RAINS. PW VALUES ARE HIGH
ENOUGH TO BE CONCERNED ABOUT POTENTIAL FOR FLASH FLOODING OVER
RECENT BURN AREAS. OREGON LOW OPENS UP AND EJECTS EAST ACROSS
PANHANDLE INTO MONTANA LATE TONIGHT INTO SUNDAY. THIS WAVE WILL DRAG
DRIER MID LEVEL AIRMASS INTO THE REGION BUT ALSO PROVIDE ENOUGH
DYNAMICS TO CONTINUE THE THREAT OF STORMS GIVEN LOW LEVEL MOISTURE.
MODELS REDEVELOP THE LOW OVER THE PACNW ON MONDAY...WHICH WILL AGAIN
ENHANCE SOUTHERLY FLOW ACROSS THE REGION AND MAINTAIN POTENTIAL FOR
MONSOONAL CONVECTION. THERE ARE SOME MODEL DIFFERENCES BY MID TO
LATE WEEK AS NEW UPPER LOW EJECTS NORTHEAST ACROSS THE PANHANDLE.
00Z ECMWF THE SLOWEST OF THE MODELS IN EJECTING OUT THE LOW THURSDAY
THROUGH FRIDAY...AND GFS DEVELOPS A THIRD UPPER LOW ALONG THE PACNW
COAST BY SATURDAY MORNING. GIVEN THE DIFFERENCES...OPTED FOR A NUDGE
TOWARD CLIMO ON THE POPS AND A BLEND OF GUIDANCE TEMPS FOR WEDNESDAY
AND BEYOND. DMH
&&

.AVIATION...MONSOONAL MOISTURE CONTINUES TO STREAM INTO THE AREA.
THIS WILL RESULT IN SHOWERS AND ISOLATED THUNDERSTORMS ACROSS THE
AREA. WITH PWAT VALUES OF AROUND 1.25 INCHES...SOME RAINFALL MAY BE
HEAVY ENOUGH TO PRODUCE MVFR CONDITIONS AT TIMES AROUND THE
TERMINALS...BUT EXPECT OVERALL VFR TO PREVAIL. DRIER AIR IS EXPECTED
TO PUSH INTO SOUTHERN IDAHO OVERNIGHT WHICH WILL MARK THE END OF
SHOWER ACTIVITY AT THE TAF SITES. AN UPPER TROUGH WILL PASS THROUGH
TOMORROW AFTERNOON WHICH COULD INCREASE WIND SPEEDS NEAR 20 KTS.

.FIRE WEATHER...CONTINUED MOIST SOUTHERLY FLOW IS EXPECTED TO
CONTINUE PAST MIDNIGHT TONIGHT. AS A RESULT...SHOWERS AND ISOLATED
THUNDERSTORMS WILL ALSO CONTINUE. THUNDERSTORM COVERAGE MAY BE
WIDELY SCATTERED AROUND MORE ORGANIZED CONVECTION...BUT CONTINUE TO
HOLD THAT FUELS AND ATMOSPHERE REMAIN MOIST ENOUGH TO CURTAIL NEW
FIRE STARTS...OR AT LEAST INHIBIT EXTREME FIRE BEHAVIOR. MOISTURE
WILL BEGIN TO SHIFT EASTWARD AS AN UPPER DISTURBANCE PASSES THROUGH
EARLY TOMORROW. WINDS WILL INCREASE TOMORROW AFTERNOON WITH GUSTS TO
20 TO 25 MPH IN SOME AREAS. SHOULD SEE LESS WIDESPREAD SHOWERS
TOMORROW WITH MOST OF THE ACTIVITY FOCUSED ON THE EASTERN HIGHLANDS.
A DRYING TREND IS EXPECTED AFTER MONDAY WITH PRECIPITATION CHANCES
MAINLY OVER THE MOUNTAINS. MODELS INDICATE THAT REMNANTS OF
HURRICANE FABIO COULD MAKE ITS WAY OVER THE NORTHWEST NEXT
WEEKEND...BUT THERE ARE SOME DISCREPANCIES IN THE TIMING AND TRACK
OF THE MOISTURE PLUME.  HINSBERGER
