405 AM MDT SUN MAR 9 2014

.SHORT TERM...TODAY THROUGH WEDNESDAY NIGHT. THE LATEST SATELLITE
IMAGERY WAS SHOWING A WARM AND VERY MOIST PACIFIC STORM SYSTEM
ADVANCING THROUGH THE PAC NW STATES THIS MORNING. THE LEADING EDGE
OF THE SYSTEM WILL OVERSPREAD THE NORTHERN AND CNTRL MOUNTAINS TODAY
WITH SNOW LEVELS RANGING FROM AROUND 6500 TO 7000 FEET WELL INTO THE
NIGHT. SOUTHWEST FACING ASPECTS WILL RECEIVE THE BULK OF THE
PRECIPITATION WITH A STRONG BURST OF ACCUMULATION ANTICIPATED
OVERNIGHT AS THE MAIN STORM TRACK BEGINS TO SETTLE INTO THE CNTRL
MOUNTAINS. THUS HAVE CONVERTED THE WINTER STORM WATCH TO A WARNING
ABOVE 7000 FEET IN THE CNTRL MOUNTAINS STARTING THIS AFTERNOON AND
ENDING MONDAY AFTERNOON...AND THE UPPER SNAKE HIGHLANDS TONIGHT
THROUGH MONDAY EVENING. BELOW 6500 FEET...MODERATE TO HEAVY RAINFALL
OVER EXISTING SNOWPACK WILL CREATE THE POTENTIAL FOR AREAL FLOODING
WITH SMALL STREAMS AND LOW LYING AREAS AT GREATEST RISK (MORE
INFORMATION BELOW IN THE HYDROLOGY SECTION). THUS HAVE INTRODUCED
AN AREAL FLOOD WATCH FOR THE WOOD RIVER REGION STARTING TONIGHT AND
CONTINUING THROUGH MONDAY...AND THE LOWER ELEVATIONS OF THE UPPER
SNAKE HIGHLANDS STARTING LATE TONIGHT AND CONTINUING THROUGH MONDAY
EVENING. PRECIPITATION WILL BEGIN TO OVERSPREAD THE SNAKE RIVER
VALLEY/PLAIN LATE TONIGHT CONTINUING THROUGH MONDAY AFTERNOON AS THE
STORM TRACK CONTINUES TO SINK SOUTH THROUGH THE REGION. NEAR
ADVISORY LEVEL WINDS ARE ANTICIPATED WITHIN THE SNAKE PLAIN MONDAY
AFTERNOON ALONG WITH A CHANCE OF THUNDERSTORMS ACROSS THE REGION AS
THE ATMOSPHERE DESTABILIZES. SNOW LEVELS WILL DROP SIGNIFICANTLY
MONDAY NIGHT WITH ACCUMULATIONS ANTICIPATED ACROSS THE UPPER AND
LOWER SNAKE RIVER PLAIN LATE MONDAY NIGHT/TUESDAY MORNING IN A
QUASI-CONVERGENT/UPSLOPE EVENT. HUSTON

EXPECT LINGERING MOUNTAIN SNOW OF 1 TO 2 INCHES ABOVE 6500 FEET
ASSOCIATED WITH AN EXITING SYSTEM ACROSS THE CARIBOU HIGHLANDS AND
THE WASATCH MOUNTAINS TUESDAY. WEDNESDAY AND THURSDAY LOOK FOR DRY
CONDITIONS ACROSS THE AREA AS UPPER LEVEL HIGH PRESSURE RIDGING
BUILDS BACK INTO THE AREA. LOOK FOR NEAR NORMAL TEMPERATURES ON
TUESDAY RISING SLIGHTLY ABOVE NORMAL WEDNESDAY AND EVEN MORE ABOVE
NORMAL ON THURSDAY. WYATT

.LONG TERM...THURSDAY THROUGH SUNDAY. BOTH THE GFS AND ECMWF HAVE
TRENDED TO A DRIER SOLUTION FOR THE LONG TERM. THURSDAY AND FRIDAY
LOOK THE DRIEST WITH A FEW PASSING CLOUDS ALONG THE DIVIDE. ON
FRIDAY MODELS ARE ALSO IN GOOD AGREEMENT OF BUILDING IN A RIDGE OFF
OF THE COAST LEAVING SE ID IN A NW FLOW. AT THIS POINT...ANY
SHORTWAVES THAT MOVE THROUGH WILL GO UP AND OVER OUR AREA AND SKIRT
PAST ALONG THE DIVIDE. THEREFORE...LEFT IN LOW CHANCE POPS ALONG THE
DIVIDE AND WY BORDER FOR FRIDAY AND SATURDAY BUT GENERALLY DRIED
THINGS OUT FOR SUNDAY AS THE RIDGE AXIS MOVES CLOSER OUR AREA.
TEMPERATURES STILL LOOK TO REMAIN ABOVE NORMAL THROUGH THE PERIOD. EP
&&

.AVIATION...AT VALLEY SITES...EXPECT CEILINGS TO BEGIN LOWERING
THROUGH THE DAY TODAY BUT REMAINING VFR. EXPECT BREEZY CONDITIONS
THIS AFTERNOON. THINGS WILL DETERIORATE MORE TO MVFR CONDITIONS
BEGINNING AROUND 10/09Z AS ANOTHER SYSTEM MOVES IN TONIGHT AND STAYS
THROUGH MUCH OF TOMORROW. FOR KSUN...RAIN SHOWERS EXPECTED TO BEGIN
MID DAY TODAY AND PERSIST THROUGH THE PERIOD WITH MVFR/IFR
CONDITIONS LIKELY. EP
&&

.HYDROLOGY...MODERATE TO HEAVY RAINFALL BELOW 6500 FEET COMBINED
WITH MELTING SNOW WILL CREATE AN INCREASED THREAT OF FLOODING FOR
SMALL STREAMS AND LOW LYING AREAS IN THE BIG AND LITTLE WOOD RIVER
REGION AND THE UPPER SNAKE HIGHLANDS. THESE AREAS INCLUDE THE CITIES
OF KETCHUM...HAILEY...ASHTON AND ST ANTHONY. A FLOOD WATCH HAS BEEN
ISSUED FOR THESE AREAS. FLOODING IS NOT EXPECTED FOR THE MAIN STEM
