AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE POCATELLO ID
219 PM MDT SUN SEP 9 2012

.DISCUSSION...LEADING SHORTWAVE MARCHING ACROSS EASTERN IDAHO
EARLY THIS AFTERNOON. EARLIER CONVECTION OVER WESTERN IDAHO HAS
WANED AS SHORTWAVE EJECTS ACROSS MORE STABLE AIR MASS WITH DRY LOW
LEVELS OVER EASTERN IDAHO. WILL KEEP POPS LOW MOST AREAS WITH
EXCEPTION OF SLIGHTLY HIGHER SCATTERED POPS ALONG THE SOUTHERN
HIGHLANDS WHERE SLIGHTLY BETTER MOISTURE PROFILES EXIST. SFC COLD
FRONT DRAPES ACROSS FCST AREA TONIGHT THROUGH EARLY MONDAY THEN
SHIFTS EAST MID MORNING.  AIRMASS STABILIZES OVERNIGHT BUT LEFT
WEAK POPS INTO MONDAY ESPECIALLY ACROSS THE SOUTHEAST AHEAD OF
LINGERING SFC TROUGH. SFC GRADIENT TIGHTENS INTO MONDAY FOR WINDY
CONDITIONS BUT WILL CONTINUE TO HOLD WINDS BELOW ADVISORY
CRITERIA. GOOD MIXING POSSIBLE BEHIND FRONT BUT STILL UNDER
INFLUENCE OF BROAD UPPER TROUGH SO THIS CONTINUES TO HAVE
IMPLICATIONS FOR FIRE CONCERNS...SEE DISCUSSION BELOW. WINDS
DECREASE LATE IN THE DAY...LEAVING COOL AND DRY CONDITIONS IN
PLACE OVER EASTERN IDAHO. LATEST MODELS PAINT TROUGH MORE SHALLOW
THAN PREVIOUS RUNS SO TEMPS SLIGHTLY WARMER THAN PREVIOUSLY
EXPECTED. HELD TEMPS NEAR OR SLIGHTLY WARMER THAN PREVIOUS FCST IN
MOST CASES. RIDGE REBOUNDS BY LATE IN THE WEEK. HOWEVER LATEST GFS
RUN FLATTENS RIDGE LATE FRIDAY INTO SATURDAY WITH SHORTWAVE
DRIVING ACROSS IDAHO AND THE GREAT BASIN. THIS WAVE DEPICTED EVEN
DRIER THAN CURRENT WAVE FOR DAY 8 SO LEFT POPS NEAR ZERO THAT FAR
OUT. DMH

&&

.AVIATION...EXPECT CONTINUED VFR AT TAF SITES.  UPVALLEY WINDS HAVE
FINALLY INCREASED AT BYI...PIH AND IDA AND EXPECT 10 TO 20 KNOT REST
OF AFTERNOON UNTIL SUNSET.  SHOULD BE ANOTHER BREEZY DAY ON MONDAY
WITH 15 TO 25 KNOT SUSTAINED WINDS EXPECTED AT BYI...IDA AND PIH
WITH GUSTS 25 TO 35 KNOTS.
GK

&&

.FIRE WEATHER...WINDS STARTING TO PICK UP THIS AFTERNOON THOUGH
STILL NOT AT WARNING LEVELS TOO MANY PLACES.  CHALLIS GUSTING 24 MPH
LAST HOUR.  WILL LEAVE RED FLAG WARNINGS OUT WITH STILL SOME
CONVECTIVE ACTIVITY DEVELOPING IN NORTHEAST NEVADA IN ZONE 412.
WILL ALSO LET THE WIND AND HUMIDITY ONES STAY IN EFFECT.  FIRE
WEATHER WATCH STILL IN EFFECT FOR MONDAY AND WILL LEAVE THAT AS IS
AND LET NEXT SHIFTS DECIDE WHETHER TO UPGRADE.  WILL STAY BREEZY
TUESDAY IN THE REGION THOUGH IT APPEARS SHOULD BE BELOW WARNING
CRITERIA.  UPPER RIDGE BUILDS IN LATE IN THE WEEK.
GK

&&

.AIR STAGNATION...SHORTWAVE TROUGH MOVING THROUGH THE REGION TODAY
INTO TONIGHT SHOULD HAVE PROVIDED ENOUGH MIXING TO HELP ALLEVIATE
SMOKE CONDITIONS IN THE CENTRAL MOUNTAINS. HOWEVER...THIS WAVE
ALSO BRINGS THE POTENTIAL FOR LIGHTNING AND GUSTY WINDS WHICH MAY
START NEW AND EXPAND EXISTING FIRES. HAVE CONTINUED AIR QUALITY
ADVISORY FOR CUSTER COUNTY UNTIL CONDITIONS HAVE IMPROVED PER DEQ
REQUEST. DMH
