AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE POCATELLO ID
144 PM MDT SAT MAY 17 2014

.SHORT TERM...TONIGHT THROUGH MONDAY NIGHT.

A DEEP LOW PRESSURE SYSTEM IS SITUATED OFF THE COAST OF WASHINGTON
THIS AFTERNOON. A COLD FRONT EXTENDS SOUTHEAST OF THE LOW INTO
SOUTHEAST OREGON. THIS FRONT WILL SLOWLY MARCH EASTWARD THROUGH
THE NIGHT AND ARRIVE IN EASTERN IDAHO EARLY SUNDAY MORNING. COOLER
TEMPERATURES ALONG WITH STRONG WINDS WILL FOLLOW THE FRONT. WINDS
LOOK STRONG ENOUGH THAT A WIND ADVISORY WILL BE ISSUED FOR PARTS
OF THE SNAKE PLAIN ON SUNDAY WHERE SUSTAINED 25 TO 30 MPH WINDS
ARE LIKELY WITH GUSTS TO 40 TO 45 MPH. SCATTERED SHOWERS AND
ISOLATED THUNDERSTORMS WILL BE POSSIBLE SUNDAY...MAINLY IN THE
CENTRAL MOUNTAINS. EXPECT MUCH LIGHTER WINDS FOR MONDAY AS THE
LOW SINKS SOUTH ALONG THE COAST AND ENTERS THE WESTERN GREAT
BASIN. EXPECT MOISTURE TO STREAM INTO THE AREA FROM THE LOW. THIS
WILL PRODUCE ISOLATED TO SCATTERED SHOWERS ALONG WITH SOME ISOLATED
THUNDER. BEST COVERAGE WILL OCCUR DURING MONDAY AFTERNOON AND
MAINLY IN THE MOUNTAINS AND HIGHLANDS.

VALLE

.LONG TERM...TUESDAY AFTERNOON THROUGH SATURDAY. UNSETTLED WEATHER
CONTINUES THROUGH MOST OF NEXT WEEKEND. THE MODELS ARE STILL
STRUGGLING AMONGST THEMSELVES EACH RUN WITH WHERE TO PLACE BANDS OF
SHOWERS AND STORMS EACH FORECAST PERIOD. IT STILL APPEARS MIDWEEK
MAY BE THE WETTEST.  THAT WILL BE AS THE FIRST CLOSED LOW ACROSS THE
SOUTHWEST WEAKENS AND ACTUALLY BEGINS TO LIFT NORTHEAST TOWARD UTAH
AND IDAHO. BEYOND THAT...WE SHOULD SEE SOME PROGRESSION IN THE
PATTERN ACROSS THE WEST. THE FLOW IS STILL SPLIT...WITH A LARGE
CLOSED LOW SLOWLY TRACKING CLOSER TO THE US/MEXICO BORDER AND IDAHO
IN MORE ZONAL FLOW BY THE WEEKEND. THE ECMWF IS SHOWING A LITTLE
MORE PRECIPITATION ON SATURDAY VS THE GFS AS IT PUSHES A LITTLE
STRONGER WAVE ACROSS THE STATE. WE ELECTED TO NOT MAKE A WHOLE LOT
OF CHANGES IN THE EXTENDED BASED ON CONTINUED UNCERTAINTY IN THE
MODELS. IT APPEARS THE ONLY REAL STRONG AND CONSISTENT TREND IS WITH
TEMPERATURES. WE SHOULD START OUT WITHIN A COUPLE OF DEGREES FROM
AVERAGE AND EVENTUALLY PUSH TO AROUND 5-10 DEGREES ABOVE BY NEXT
WEEKEND. OVERNIGHT LOWS WILL STILL BE MILD EVEN FOR SOME OF OUR
MOUNTAINOUS AREAS. KEYES

&&

.AVIATION...VFR WEATHER IS LIKELY THROUGH TOMORROW ACROSS EASTERN
IDAHO. WE ARE STILL EXPECTING SHOWERS AND STORMS ESPECIALLY TOMORROW
AFTERNOON. FOR TODAY...STORMS SHOULD NOT AFFECT ANY OF OUR TAF
SITES...BUT IT IS NOT A ZERO PROBABILITY SITUATION. FOR
SUNDAY...KSUN WOULD MOST LIKELY BE AFFECTED BY LATE MORNING AND
AFTERNOON. THERE IS A SMALL CHANCE FOR KBYI/KIDA/KPIH IN THE
AFTERNOON.  THE BIGGER ISSUE FOR THOSE SITES MAY BE STRONG WEST TO
SOUTHWEST WINDS ACROSS THE PLAIN. SUSTAINED WINDS OF 20-30KTS WITH
HIGHER GUSTS ARE FORECAST. KEYES

&&

.FIRE WEATHER...UPPER RIDGING OVER THE NORTHERN ROCKIES TODAY WILL
MOVE EAST...ALLOWING FOR ISOLATED THUNDERSTORMS THIS AFTERNOON AND
EVENING MAINLY ALONG THE DIVIDE. A MAJOR UPPER TROF SYSTEM MOVES
INTO THE PACIFIC NORTHWEST ON SUNDAY BRINGING INCREASED CHANCES FOR
SHOWERS AND THUNDERSTORMS MAINLY OVER THE CENTRAL IDAHO MOUNTAINS
AND UPPER SNAKE HIGHLANDS. WINDS WILL ALSO PICK UP ON SUNDAY. COOLER
TEMPERATURES AND HIGHER HUMIDITY WILL BE THE TREND FOR NEXT WEEK AS
THE UPPER SYSTEM CONTINUES TO DOMINATE THE WEST. HEDGES
