AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE POCATELLO ID
304 AM MDT TUE APR 27 2010

.SHORT TERM...TODAY THROUGH THURSDAY NIGHT.
QUITE AN ACTIVE PERIOD ON TAP. THE UPPER RIDGE THAT BROUGHT THE
RELATIVELY TRANQUIL WEATHER THIS WEEKEND AND MONDAY IS NOW MOVING
TO THE EAST. A POTENT STORM THAT HAS MOVED ONSHORE IN THE PACIFIC
NORTHWEST IS NOW MOVING TOWARD IDAHO. WE EXPECT PRECIPITATION TO
SPREAD INTO THE CENTRAL MOUNTAINS AROUND NOON AND THEN SPREAD WEST
TO EAST ACROSS THE CWA THIS AFTERNOON AND EVENING. AHEAD OF THE
SYSTEM WE SHOULD SEE ONE MORE WARM DAY ACROSS THE SNAKE PLAIN.
WITH SOUTHERLY FLOW AND DOWNSLOPING MANY PLACES SHOULD SEE HIGHS
IN THE 70S ESPECIALLY IN LOWER SNAKE PLAIN.

THE FIRST ISSUE FOR LATE TODAY AND INTO THIS EVENING WILL BE FOR
WINDS. LOCAL WIND STUDY SCHEMES SHOW ADVISORY LEVEL WINDS FOR LATE
THIS AFTERNOON INTO THIS EVENING. MAIN DRIVING FACTORS ARE STRONG
700 AND 500 MB WINDS ALONG WITH AN 140 KNOT JET AND GOOD COLD
ADVECTION. THEREFORE WE HAVE ISSUED A WIND ADVISORY FOR THE SNAKE
PLAIN ALONG WITH SOUTH CENTRAL AND CARIBOU HIGHLANDS ESPECIALLY IN
NORTH TO SOUTH ORIENTED VALLEYS.

THE SECOND ISSUE IS FOR THE POSSIBILITY OF THUNDERSTORMS. THERE
WILL BE GOOD DIVERGENCE ALOFT WITH THE AREA IN THE LEFT FRONT QUAD
OF THE 140 KNOT JET STREAK THIS AFTERNOON. LIFTED INDICES ARE
PROGGED TO BE AROUND -2 WITH GOOD FORCING FROM THE APPROACHING
COLD FRONT THAT WILL MOVE THROUGH AT THE TIME OF MAXIMUM HEATING.
THE SPC HAS THE CWA IN A SEE TEXT AREA. WITH STRONG WINDS ALOFT
ALONG WITH SHEAR IT WOULD NOT SURPRISE ME TO SEE SOME STRONG WIND
GUSTS OR SMALL HAIL WITH ANY THUNDERSTORM LATE TODAY.

THE THIRD ISSUE IS FOR SNOW. PRECIPITATION WILL SPREAD INTO THE
CENTRAL MOUNTAINS LATE THIS MORNING AND CONTINUE THROUGH THE DAY
AND INTO THE NIGHTTIME AND WEDNESDAY. WITH MUCH COLDER AIR MOVING
IN WE HAVE ISSUED A WINTER WEATHER ADVISORY BEGINNING AT NOON FOR
LOCATIONS ABOVE 7000 FEET FOR THE POSSIBILITY OF 5 TO 10 INCHES OF
SNOW ALTHOUGH THE BEST CHANCE OF 10 INCHES WILL BE AT THE HIGHEST
ELEVATIONS.

FOR WEDNESDAY THROUGH THURSDAY NIGHT THE WEATHER WILL REMAIN
RATHER CHILLY BLUSTERY AND UNSETTLED WITH A BROAD TROUGH OVER THE
REGION THAT WILL BRING SOME ROUNDS OF SHOWERS WITH THE BEST
CHANCES IN THE CLIMATOLOGICALLY FAVORED UPSLOPE REGIONS. WINDS
WILL REMAIN STRONG THROUGH THE PERIOD AND ADDITIONAL WIND
ADVISORIES MAY BE NEEDED WEDNESDAY OR THURSDAY ESPECIALLY FOR THE
SNAKE PLAIN. HATTINGS

.LONG TERM...RIDAY THROUGH MONDAY. FRIDAY MORNING A BROAD LOW
PRESSURE TROUGH WILL BE OVER THE WESTERN HALF OF THE CONUS WITH
UNSETTLED NORTHWEST FLOW INTO IDAHO. MODEL DIFFERENCE DEVELOP
QUICKLY. CURRENT FORECAST LEANS TOWARDS THE HPC SOLUTION WITH MORE
POLAR JET BRANCH ENERGY CROSSING THE GULF OF ALASKA AND FLATTENING
THE EASTERN PACIFIC RIDGE SUBSTANTIALLY SATURDAY THROUGH MONDAY.
THAT LEAVES TEMPERATURES BELOW NORMAL AND UNSETTLED CONDITIONS
THROUGH THE PERIOD. CLIMATOLOGY WAS USED EXTENSIVELY AS TIMING OF
EMBEDDED FEATURES WILL BE DIFFICULT. RS

&&

.AVIATION...PACIFIC COLD FRONT WILL REACH KSUN NEAR 22Z AND KPIH
NEAR 01Z. INCREASING AND LOWERING CLOUDS WILL BE THE RULE TODAY WITH
A SLIGHT CHANCE OF THUNDERSTORMS NEAR FRONTAL PASSAGE. AT
KSUN...MVFR CEILINGS FIRST EXPECTED NEAR 02Z...SNOW LEVELS WILL
LOWER TO NEAR 7000 FT MSL BY 06Z AND VALLEY FLOORS BY WEDNESDAY
MORNING. AT KIDA AND KPIH...MVFR CEILINGS FIRST EXPECTED NEAR
06Z...SNOW LEVELS WILL LOWER TO NEAR 5000 FT MSL BY WEDNESDAY
MORNING. RS
