AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE BOISE ID
250 PM MDT FRI MAR 30 2012

.SHORT TERM...TONIGHT THROUGH SUNDAY...AN ACTIVE WEEKEND IS ON TAP
WEATHERWISE WITH A COUPLE MORE SYSTEMS TO MOVE THROUGH THE AREA. THE
LONG PLUME OF HIGH PWAT MOISTURE FROM THE PACIFIC IS FORECAST TO
REDIRECT NORTHWARD TONIGHT AS A STRONG SHORT WAVE DIGS SOUTH ALONG
THE WEST COAST. THIS REORIENTATION OF MOISTURE WILL BRING DRIER AND
WARMER CONDITIONS TO THE REGION TEMPORARILY TONIGHT AND SATURDAY AS
SOUTHEAST OREGON AND SOUTHWEST IDAHO GET INTO THE WARM SECTOR OF AN
POTENT OPEN WAVE SYSTEM. WITH GOOD WARMING EXPECTED SATURDAY AND
COOLING ALOFT SATURDAY AFTERNOON...POTENTIAL FOR THUNDERSTORMS IS
INCREASING. MEANWHILE...A STRONG JETSTREAM WILL PUNCH NORTHEAST FROM
CALIFORNIA PLACING THE FORECAST AREA IN A FAVORABLE LOCATION FOR
CONVECTIVE DEVELOPMENT. LATEST MODELS SHOW LI/S AS LOW AS MINUS 3
AND CAPE AROUND 400 J/KG OVER THE WEST CENTRAL MOUNTAINS SOUTH TO
THE SNAKE RIVER. AT THE PRESENT TIME THE STORM PREDICTION CENTER
ALSO HAS THE AREA OUTLINED FOR GENERAL THUNDERSTORMS. THIS
CONVECTIVE ACTIVITY WILL OCCUR JUST AHEAD OF A STRONG SHORT WAVE AND
SURFACE COLD FRONT WHICH WILL MOVE THROUGH EARLY SUNDAY MORNING.
ABUNDANT RAINFALL IS EXPECTED TO FALL ALONG AND AHEAD OF THIS FRONT
WHILE SNOW LEVELS REMAIN QUITE HIGH. ONCE THE FRONT
PASSES...TEMPERATURES WILL DROP AS MUCH AS 20 DEGREES OFF SATURDAY
HIGHS AND THE AIR MASS WILL DESTABILIZE INTO A COLDER SHOWERY REGIME
WITH RAPIDLY FALLING SNOW LEVELS. A WIND ADVISORY HAS BEEN HOISTED
FOR SATURDAY AFTERNOON IN SOUTHEAST OREGON AND SOUTHWEST IDAHO NEAR
THE NEVADA BORDER AS STRONG UPPER WINDS WORK NORTHEAST OVER THE
AREA. THUNDERSTORM DEVELOPMENT MAY PROVIDE ADDITIONAL MECHANISMS FOR
STRONG DOWNDRAFTS. ANOTHER WIND ADVISORY MAY BE NEEDED IN THE MAGIC
VALLEY SUNDAY POST COLD FRONTAL.

.LONG TERM...SUNDAY NIGHT THROUGH FRIDAY...TYPICAL SPRING TIME
WEATHER PATTERN CONTINUES OVER IDAHO FOR THE EXTENDED PERIOD AS THE
AREA WILL SEE A ROLLER COASTER RIDE IN TEMPERATURES. THE WEEKEND
TROUGH PUSHES OUT SUNDAY WITH YET ANOTHER STORM OFF THE COAST. AS
THE LOW PINWHEELS OFF THE COAST...A RIDGE AMPLIFIES OVER THE AREA
MONDAY AND TUESDAY. TEMPERATURES WILL START OFF NEAR NORMAL THEN
WARM TO WELL ABOVE NORMAL FOR THE FIRST PART OF THE WEEK. MODELS ARE
SHOWING SOME MID LEVEL MOISTURE MOVING INTO SOUTHEAST OREGON AND
INTO WESTERN IDAHO TUESDAY AFTERNOON AHEAD OF THE NEXT COLD FRONT.
SO SLIGHT CONCERN AT THIS TIME FOR A MENTION OF THUNDERSTORMS
TUESDAY AFTERNOON. NONE OF THE GRIDDED MODELS SHOW THIS AT THIS TIME
BUT WILL HAVE TO BE WATCHED OVER THE WEEKEND. BOTH THE GFS AND ECM
SHOW THIS NEXT COLD FRONT TO PUSH INTO THE REGION ON WEDNESDAY AND
THE UPPER LOW BY THURSDAY MORNING. SNOW LEVELS START NEAR VALLEY
FLOORS SUNDAY THEN MONDAY AND TUESDAY RANGE FROM 5-6000 FEET IN THE
NORTH AND 6-7000+ FEET IN THE SOUTH THEN LOWER TO AROUND 4000 FEET
BY THE END OF THE WEEK.

&&

.AVIATION...FOR THE REMAINDER OF THIS AFTERNOON THROUGH EARLY
EVENING SCATTERED MVFR CONDITIONS IN -RA AND LOW CLOUDS EXPECTED...
OTHERWISE VFR CONDITIONS WILL PREVAIL. STRONG SW-SE WINDS WILL ALSO
CONTINUE THROUGH THE EARLY EVENING HOURS ACROSS EASTERN OREGON WITH
GUSTS 25-45 MPH. SHOWER ACTIVITY WILL BEGIN TO PUSH NORTH OVERNIGHT.
WINDS IN THE 8-10KFT LEVEL SW 10-15 KTS OVER IDAHO AND 25-30 KTS
OVER EASTERN OREGON.

FOR SATURDAY...WINDS IN THE 8-10KFT LEVEL WILL BE INCREASING INTO
THE 40-50KTS RANGE...SO ONCE THE MORNING INVERSION BREAKS EXPECT
SURFACE WINDS OVER THE OREGON ZONES TO BE 30-40 MPH WITH HIGHER
GUSTS. OVER THE IDAHO ZONES SURFACE WINDS AROUND 15-25 KTS. LIGHTER
WINDS SUNDAY AREA WIDE BUT SHIFTING TO THE NORTHWEST.

&&

.HYDROLOGY...AREA STREAMS AND CREEKS ARE EXPECTED TO SHOW RISES
THROUGH THE WEEKEND DUE TO WARM TEMPERATURES THROUGH SATURDAY AND
ADDITIONAL RAINFALL OVER ALREADY WET SOILS. MAINSTEM RIVERS AT
PRESENT SHOULD REMAIN BELOW FLOOD STAGE BUT THE WEISER RIVER AT
WEISER WILL BE BANKFULL AND CREST JUST BELOW FLOOD STAGE OF 9.5 FEET
ON SATURDAY. THIS COULD CHANGE WITH HIGHER QPF AMOUNTS FROM HEAVY
CONVECTIVE SHOWERS. THE PAYETTE AT EMMETT IS EXPECTED TO CREST AT
9.0 FEET SATURDAY AFTERNOON...BELOW FLOOD STAGE OF 10.5 FEET. ROCK
AND MUDSLIDES ARE ALSO A POSSIBILITY THIS WEEKEND ALONG WITH RUNOFF
ALONG MOUNTAIN HIGHWAYS AND SECONDARY ROADS.
