AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE POCATELLO ID
131 PM MST SUN JAN 18 2015

.SHORT TERM...WARM MOIST PACIFIC FLOW WITH EMBEDDED ENERGY
CONTINUES TO SPREAD OVER THE REGION THIS AFTERNOON. RECORD AND
NEAR RECORD TEMPERATURES OCCURRED AT SOME LOCATIONS IN SOUTHERN
IDAHO. DUE TO THE WARMING...RAIN SHOWERS HAVE BEEN AS HIGH AS 8000
FEET. WITH THE MAIN FLOW SAGGING SOUTH OVERNIGHT AND A WEAK COLD
FRONT SLIDING BY OVERNIGHT WILL LIMIT THE OVERALL AMOUNT OF MID
AND UPPER LEVEL SNOWFALL. HAVE DECIDED TO LET THE TWO WINTER
ADVISORIES EXPIRE BEFORE 3 PM. THE BIGGEST IMPACT AREA THROUGH
EARLY THIS EVENING WILL BE GOING OVER MONIDA PASS. SOME LINGERING
SHOWERS POSSIBLE TOMORROW IN THE UPPER SNAKE HIGHLANDS...TETON
RANGE AND ISLAND PARK REGION. OTHERWISE FORECAST CONFIDENCE
REMAINS STRONG FOR A RIDGE OF HIGH PRESSURE TO DOMINATE OUR
PATTERN. THERE IS A POTENTIAL FOR FOG TO REFORM IN THE SNAKE RIVER
VALLEY BY MONDAY NIGHT INTO TUESDAY SO WILL MONITOR THIS FOR
IMPACT CONCERNS.  PRESTON

.LONG TERM...TUESDAY NIGHT THROUGH SUNDAY NIGHT. MODELS
CONTINUE TO SHOW HIGH PRESSURE RIDGING BRINGING DRY CONDITIONS
WEDNESDAY AND THURSDAY. A VERY WEAK SYSTEM WILL MOVE THROUGH THE
AREA FRIDAY INTO SATURDAY BRINGING LIGHT MOUNTAIN SNOW. EXPECT
SLIGHTLY COOLER THAN NORMAL TEMPERATURES ON WEDNESDAY BEFORE
BECOMING SIGHTLY ABOVE NORMAL BY THE WEEKEND. WYATT

&&

.AVIATION...A WEAK SYSTEM WILL MOVE THROUGH THIS AFTERNOON INTO
TOMORROW MORNING. LOOK FOR MVFR/IFR CONDITIONS FOR KSUN WITH RAIN
AND A RAIN/SNOW MIX THIS AFTERNOON INTO EARLY EVENING BEFORE
BECOMING VFR AND STAYING VFR THROUGHOUT THE REMAINDER OF THE PERIOD.
LOOK FOR BREEZY WINDS ACROSS THE SNAKE RIVER PLAIN AND EASTERN MAGIC
VALLEY WITH THIS SYSTEM. MODELS ARE STILL SHOWING RAIN FOR KIDA AND
TO AN LESSER EXTENT FOR KPIH EARLY THIS EVENING AND CONTINUING OFF
AND ON THROUGH MOST OF THE EVENING. EXPECT MVFR CONDITIONS DURING
RAIN SHOWERS AND IFR CONDITIONS DURING HEAVIER RAIN SHOWERS. MODELS
SHOW KIDA KEEPING MVFR CIGS UNTIL EARLY TOMORROW AFTERNOON. KPIH
WILL LIKELY BECOME VFR BY EARLY TO MID TOMORROW MORNING. KBYI WILL
LIKELY STAY VFR THROUGHOUT THE PERIOD THOUGH MODELS ARE HINTING
BRIEF MVFR CIGS IN THE EVENING. WYATT
