AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE POCATELLO ID
211 PM MDT FRI JUN 4 2010

.SHORT TERM...TONIGHT THROUGH SUNDAY NIGHT.

MOIST ZONAL FLOW CONTINUES ACROSS THE REGION. SATELLITE SHOWS AN
UPPER LEVEL JET STREAK MOVING THROUGH THE AREA WHICH IS CAUSING
WIDESPREAD PRECIPITATION. EXPECT THIS PRECIPITATION TO GRADUALLY
DIMINISH THROUGHOUT THE NIGHT. LATEST MODEL RUNS SHOW A BIT OF A
REPRIEVE FOR SATURDAY. HOWEVER...WITH THE AMOUNT OF MOISTURE
AROUND...STILL CANT ENTIRELY RULE OUT A STRAY SHOWER. NEXT HEALTHY
DISTURBANCE MOVES THROUGH THE REGION ON SUNDAY. THE NAM/EUROPEAN
ARE BRINGING WIDESPREAD PRECIPITATION TO THE CENTRAL MOUNTAINS AND
UPPER SNAKE HIGHLANDS. WHILE THE GFS IS CARRYING THIS SYSTEM
FURTHER NORTH. FOR NOW...AM LEANING TOWARDS THE EUROPEAN/NAM
SOLUTIONS.

.LONG TERM...MONDAY THROUGH NEXT FRIDAY.

MODELS CONTINUE TO BE AT ODDS THROUGH THE LONG RANGE. GFS BRINGS
A RIDGE INTO THE GREAT BASIN MONDAY THROUGH TUESDAY NIGHT WHILE
THE ECMWF PERSISTS WITH THE CURRENT MOIST ZONAL PATTERN. BOTH
MODELS DO INDICATE THAT A DEEPER WAVE MOVES INTO THE AREA FROM THE
PACIFIC NORTHWEST ON WEDNESDAY AND THURSDAY. HAVE ADJUSTED POPS
UPWARDS ACROSS THE BOARD FOR MIDWEEK NEXT WEEK. WITH BOTH MODELS
SHOWING A WETTER PATTERN LATE WEEK AND THEREFORE HAVE ALSO TRENDED
LOWER ON HIGH TEMPS.

&&

.AVIATION...RAIN SHOWERS WILL CONTINUE ACROSS THE FORECAST AREA
THROUGH LATE THIS EVENING...DIMINISHING AFTER MIDNIGHT. ISOLATED
THUNDERSTORMS ARE POSSIBLE THIS EVENING. OCCASIONAL MVFR CEILINGS
CAN BE EXPECTED IN THE SHOWERS...OTHERWISE VFR WILL BE THE
PREDOMINANT CONDITION.  SHOWERS ARE EXPECTED TO BE MORE ISOLATED ON
SATURDAY.

&&

.HYDROLOGY...WIDESPREAD RAINFALL TODAY AND TONIGHT WILL CONTINUE TO
PRODUCE ELEVATED RIVER AND STREAM LEVELS ACROSS MUCH OF EASTERN
IDAHO THIS AFTERNOON AND THIS WEEKEND. AREAS OF PARTICULAR CONCERN
ARE THE CENTRAL MOUNTAINS AND THE HENRYS FORK AND TETON RIVER
BASINS. THE TETON RIVER NEAR ST. ANTHONY IS EXPECTED TO REACH
BANKFULL LEVEL LATE TONIGHT AND THE HENRYS FORK RIVER NEAR REXBURG
IS EXPECTED TO REACH BANKFULL BY SUNDAY. TRIBUTARIES FLOWING INTO
THESE RIVERS WILL ALSO BE RUNNING HIGH.

STREAM GAGES ON THE SALMON RIVER NEAR SUNBEAM AND THOMPSON CREEK AND
SQUAW CREEK IN THE CENTRAL MOUNTAINS INDICATE SHARP RISES IN WATER
LEVELS...AS WELL AS GAGES ALONG UPPER PORTIONS OF THE BIG LOST
RIVER. REPORTS OF FLOODING DUE TO CREEKS BEING OUT OF THEIR BANKS
AND WATER OVER SOME ROADS IN AND AROUND STANLEY HAVE BEEN
RECEIVED.

FLOODING OF LOW LYING AREAS ADJACENT TO SOME STREAMS AND RIVERS WILL
REMAIN POSSIBLE INTO THE WEEKEND. SOILS IN SOME AREAS HAVE BECOME
SATURATED WHICH WILL INCREASE THE RISK OF FLOODING AS WELL AS MUD
AND DEBRIS SLIDES IN AREAS OF STEEP TERRAIN AND NEAR OLD FOREST FIRE
BURN SCARS.
