AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE POCATELLO ID
905 AM MDT TUE APR 6 2010

.SHORT TERM...TODAY THROUGH THURSDAY NIGHT. ONGOING LIGHT SNOW
CONTINUING ACROSS THE ERN FOOTHILLS/HIGHLANDS THIS MORNING AS THE
SRN BRANCH OF THE UPPER LOW WAS PUSHING INTO SE WYOMING. REMAINS OF
NRN BRANCH OF UPPER LOW ARE PROGGED TO SHEAR SE ACROSS THE REGION
THIS AFTERNOON/EVENING AND MAY YET TRIGGER A SNAKE PLAIN CONVERGENCE
EVENT. THE MODELS HAVE BEEN ON AGAIN/OFF AGAIN WITH THIS FEATURE THE
LAST COUPLE OF DAYS AND THE LATEST 12Z MODEL CYCLE WAS SHOWING THE
POTENTIAL FOR A WEAK-MODERATE EVENT STARTING AROUND 3 PM THIS
AFTERNOON. IF THE EVENT DEVELOPS WE WILL COVER IT WITH A SHORT-FUSED
ADVISORY OR SPECIAL STATEMENT (SPS) WITH THE EXPECTATION THAT WE
COULD SEE 1-3 INCHES OF NEW SNOWFALL AS THE CONVERGENCE ZONE TARGETS
MAINLY BLACKFOOT WITH IDAHO FALLS AND POCATELLO TRENDING TOWARD THE
LOWER END OF THAT RANGE.  FOR NOW...ADVISORIES WILL CONTINUE ACROSS
THE ERN HIGHLANDS AND A WIND ADVISORY HAS BEEN ISSUED FOR THE
SOUTH-CNTRL HIGHLANDS. MAY YET SEE WINDS RAMP UP TO ADVISORY LEVELS
IN BURLEY AND POCATELLO THIS AFTERNOON. WE WILL CONTINUE TO MONITOR
THIS POTENTIAL DEVELOPMENT AS WELL AS THE AFOREMENTIONED CONVERGENCE
EVENT SITED ABOVE. SEE PREVIOUS DISCUSSION BELOW. HUSTON

RAN THE ADVISORIES AND WARNINGS OUT THROUGH 10 AM THIS MORNING FOR
EASTERN ZONES INCLUDING THE UPPER SNAKE RIVER PLAIN WHICH I ADDED
TO THE ADVISORY AFTER MIDNIGHT. HEAVY SNOW HAS BEEN FALLING IN
IDAHO FALLS FOR SEVERAL HOURS NOW AND EXPECT UP TO 5 INCHES IN THE
UPPER SNAKE PLAIN THROUGH MID MORNING. CANCELED THE ADVISORY FOR
THE CENTRAL MOUNTAINS AS PRECIPITATION HAS MOVED EAST AND HAS BEEN
FOCUSED IN THE UPPER SNAKE PLAIN THIS MORNING AS CONVERGENCE
PATTERN HAS EMERGED AS THE INVERTED UPPER TROF PUSHES EAST.
SATELLITE INDICATING DEEP MOISTURE WITH THE COLD CLOUD TOPS MOVING
SLOWLY NORTHEAST THIS MORNING. EXPECT THE STEADY SNOW TO TAPER OFF
BY MID MORNING IN THE FAR EAST AND EXPECT CONVECTIVE SNOW SHOWERS
THIS AFTERNOON WITH STEEP LOW LEVEL LAPSE RATES SETTING UP WITH
HIGHEST POPS ALONG THE WYOMING BORDER. STRONG WINDS TODAY IN THE
SNAKE RIVER PLAIN AS WELL AND EXPECT SUSTAINED 20 TO 30 MPH WINDS
FROM BURLEY THROUGH POCATELLO. RIDGE BEGINS BUILD IN TONIGHT AND
WEDNESDAY AND EXPECT MAINLY DRY WEATHER ACROSS THE REGION. NEXT
SYSTEM OFF THE PACIFIC MOVES THROUGH THURSDAY AND THERE WILL BE A
CHANCE FOR MOUNTAIN PRECIPITATION WITH A COLD FRONTAL PASSAGE.
SHOULD BE MILD THURSDAY AHEAD OF THE FRONT. GK

.LONG TERM...FRIDAY THROUGH MONDAY. NOT MANY CHANGES TO THE LONG
RANGE AS CONTINUITY LOOKS REASONABLE FOR THE MOST PART. SOME UPSLOPE
SHOWERS MAY LINGER ACROSS THE FAVORED AREAS IN THE HIGHER ELEVATIONS
BUT MAINLY DRY CONDITIONS ARE EXPECTED FOR THE SNAKE PLAIN. SHORT
WAVE RIDGING SHOULD BRING MAINLY DRY CONDITIONS FOR FRIDAY NIGHT.
STILL LIKE THE IDEA OF THE DEEPENING TROUGH ALONG THE WEST COAST OF
THE US THAT WILL MOVE ONSHORE FOR SUNDAY AND INTO MONDAY.
TEMPERATURES LOOK TO BE BELOW NORMAL FOLLOWING THE FRONTAL PASSAGE
FRIDAY WITH A GRADUAL WARMING TREND THROUGH THE WEEKEND AS SOUTHERLY
FLOW INCREASES AHEAD OF THE NEXT TROUGH. POPS MAY INCREASE FOR EARLY
NEXT WEEK WITH THE NEXT SYSTEM APPROACHING FROM THE WEST BUT TIMING
IS STILL A BIT UNCERTAIN. CH
&&

.AVIATION...EXPECT MOSTLY VFR CONDITIONS FOR ALL SITES EXCEPT KIDA
THROUGHOUT THE PERIOD. TROUGHING BEHIND COLD FRONTAL PASSAGE IS
CONTINUING TO BRING SNOW SHOWERS AND IFR/LIFR CONDITIONS TO KIDA.
LOOK FOR THESE SNOW SHOWERS TO CONTINUE THROUGH EARLY MORNING. BY
EARLY TO MID MORNING LOOK FOR LOW STRATUS CIGS TO LIFT AT KIDA.
EXPECT MOSTLY VFR CONDITIONS FOR KIDA THE REMAINDER OF THE PERIOD
WITH AFTERNOON VICINITY SHOWERS.  KPIH WILL SEE VICINITY SNOW
SHOWERS EARLY THIS MORNING TEMPORARILY BRINGING MVFR CONDITIONS OFF
AND ON. LOOK FOR SLIGHTLY ELEVATED WINDS THROUGH THE NIGHT ACROSS
THE SNAKE RIVER PLAIN WITH WINDS TO INCREASE IN THE AFTERNOON.
WINDS WILL DIE OFF TOMORROW NIGHT WITH HIGH PRESSURE BUILDING IN THE
AREA. WYATT
