AREA FORECAST DISCUSSION...UPDATED
NATIONAL WEATHER SERVICE BILLINGS MT
447 PM MDT SAT AUG 12 2006
.SHORT TERM...VALID FOR SUN AND MON...
UPDATED TO INCLUDE SEVERE THUNDERSTORM WATCH.
SHORT WAVE TROUGH MOVING INTO IDAHO LOOKS FAIRLY IMPRESSIVE ON
WATER VAPOR IMAGERY. MODELS...ESPECIALLY 12Z GFS...SEEM TOO SLOW
WITH THIS FEATURE. CONVECTION IS STARTING TO FIRE AHEAD OF THIS
TROUGH OVER EASTERN IDAHO UP THROUGH MONTANA. THIS TROUGH WILL BE
THE FEATURE OF INTEREST...ALONG WITH A WEAKER SHORT WAVE DROPPING
SOUTHEAST OUT OF BRITISH COLUMBIA THE NEXT 36 HOURS. MODELS AND
OBSERVATIONAL DATA ARE GIVING A LOT OF REASONS FOR A WIDESPREAD
RAIN EVENT...AND NOT MANY AGAINST THE IDEA. THERE IS STILL A FAIR
AMOUNT OF UNCERTAINTY REGARDING PLACEMENT OF THE PRECIPITATION
BULLS EYE AND TO A DEGREE TIMING. EVEN WITH UNCERTAINTY OF
PRECIPITATION PLACEMENT ...IT APPEARS MOST LOCATIONS SHOULD SEE AT
LEAST SEE SOME. SO DESPITE THE RECENT DRY SPELL...WILL FORECAST A
RAIN EVENT ACROSS THE CWA THAT HAS NOT BEEN SEEN IN OVER A MONTH.
HAVE RAISED POPS TO CATEGORICAL OR LIKELY FOR TONIGHT AND KEPT IT
GOING THROUGH SUNDAY MORNING. 500MB TEMPS DROPPING TO NEAR 15 BELOW
ZERO CELSIUS SHOULD HELP AFTERNOON CONVECTION GOING AS WELL...SO
SPREAD SOME LOW POPS WEST FOR SUNDAY AFTERNOON. IF THE SYSTEM
SLOWS DOWN EVEN MORE THAN EXPECTED...SUNDAY AFTERNOON POPS MAY BE ON
THE LOW SIDE. TEMPS ON SUNDAY ARE TRICKY AS WELL. HAVE KNOCKED A
FEW MORE DEGREES OFF FORECAST HIGHS OVER THE EASTERN ZONES TO THE
LOWER 70S. IF RAIN HANGS ON...HIGH TEMPERATURES COULD BE IN THE
MID 60S.
SUNDAY NIGHT LOOKS COOL BEHIND THE SYSTEM. EVEN HAVE TO WONDER IF
FOG MAY DEVELOP AFTER RECENT RAINS OVER EASTERN SECTIONS...BUT
WILL NOT FORECAST IT NOW WITH A LOT RIDING ON THE AMOUNT OF RAIN
THAT FALLS AND OTHER FACTORS. BUILDING RIDGE ALOFT SHOULD ALLOW
FOR A WARMER AND DRIER DAY ON MONDAY. BUT IF AREA DOES SEE A
DECENT RAIN...EVAPORATION COULD PLAY A ROLE IN KEEPING TEMPS DOWN
SLIGHTLY. HAVE NUDGED TEMPS DOWN IN THE FAR EAST WITH THIS THIS
IDEA IN MIND. MOORE
.LONG TERM...VALID FOR TUE...WED...THU...FRI...SAT...
GOING EXTENDED FORECAST WAS IN GOOD SHAPE. FORECAST AREA WILL BE
UNDER SW FLOW ALOFT AHEAD OF A PACIFIC TROUGH THROUGH THU. THE
TROUGH WAS THEN FORECAST TO WEAKEN AS IT MOVES ACROSS THE REGION
LATE IN THE WEEK. POPS WERE ON TRACK OVER WESTERN ZONES TUE
AFTERNOON AND EVENING AS SHORTWAVE ENERGY MOVES NE INTO THE AREA.
MAY NEED TO ADD POPS LATE TUE NIGHT AS ENERGY WILL CONTINUE MOVING
THROUGH THE AREA. WILL BRIEF LATER SHIFTS ON THIS POSSIBILITY.
POPS ACROSS THE AREA WED AND THU AFTERNOON AND EVENING LOOKED
FINE. ENSEMBLES SUPPORTED GOING TEMPERATURE FORECAST OF NORMAL TO
SLIGHTLY ABOVE NORMAL TEMPERATURES. ARTHUR

.AVIATION...
SHOWERS AND THUNDERSTORMS WILL OVERSPREAD THE ROUTES FROM WEST TO
EAST TONIGHT. SCATTERED MVFR CONDITIONS WILL OCCUR WITH THE
PRECIPITATION. ISOLATED IFR CONDITIONS WILL BE POSSIBLE WITH AREAS
OF HEAVY RAIN. SHOWERS AND ISOLATED THUNDERSTORMS WILL CONTINUE
MAINLY EAST OF KBIL SUNDAY MORNING WITH ASSOCIATED MVFR
CONDITIONS. VFR CONDITIONS WILL RETURN TO THE REGION SUNDAY
AFTERNOON. ARTHUR
