AREA FORECAST DISCUSSION...UPDATED
NATIONAL WEATHER SERVICE BILLINGS MT
928 AM MDT THU AUG 17 2006
.MORNING UPDATE...
ACTIVE DAY IN STORE ACROSS THE FORECAST AREA AS A LARGE TROUGH
OVER OREGON AND IDAHO WILL MOVE EAST ACROSS THE STATE TODAY.
THUNDERSTORMS CONTINUE TO DEVELOP AND INCREASE IN COVERAGE ACROSS
THE GREAT FALLS AND GLASGOW AREAS WITH MOVEMENT TO THE NORTHEAST.
SATELLITE SHOWING LOW CLOUD DECK OVER PORTIONS OF OUR CENTRAL
ZONES BUT THIS IS SHOWING SIGNS OF DISSIPATING. PLENTY OF CLEAR
SKIES ACROSS EASTERN IDAHO AND NORTHERN WYOMING AND BELIEVE THIS
CLEARING WILL MOVE INTO OUR AREA LATER THIS MORNING AND DURING
THE AFTERNOON. WILL THEREFORE LOWER SKY COVER GRIDS TO REFLECT
THIS. HAVE ALSO REMOVED POPS ACROSS ALL BUT THE FAR
NORTHEAST...NORTHERN AND WESTERN ZONES FOR THIS MORNING.
AS THE TROUGH MOVES EAST THIS AFTERNOON...SHOWERS AND
THUNDERSTORMS ARE EXPECTED TO DEVELOP ACROSS THE FORECAST AREA
WITH THE BEST CHANCES OVER THE WESTERN ZONES. A SURFACE LOW FORMS
THIS AFTERNOON OVER NORTHEAST WYOMING SETTING UP A BAROCLINIC
ZONE FROM THE WESTERN DAKOTAS TO NORTHERN WYOMING. THUNDERSTORMS
ARE EXPECTED TO DEVELOP OVER THE BIG HORNS AND HIGHER TERRAIN OF
SOUTHERN MONTANA/NORTHERN WYOMING. PLENTY OF LOW LEVEL MOISTURE
COMBINED WITH AN EASTERLY SURFACE FLOW AND SHEAR ALOFT WILL ALLOW
FOR THE POSSIBILITY OF SEVERE THUNDERSTORMS. WILL ADD SEVERE
WORDING TO ZONES FROM EASTERN YELLOWSTONE COUNTY AND AREAS EAST.
ONE CONCERN FOR PRECIPITATION IS THE POSSIBILITY OF BEING DRY
SLOTTED AS WATER VAPOR IMAGERY SHOWING A DRY SLOT MOVING INTO
SOUTHWEST MONTANA. IN ANY CASE...WILL LEAVE CURRENT AFTERNOON AND
EVENING POPS AS IS AND CONTINUE TO MONITOR THROUGHOUT THE DAY.
UPDATE OUT SHORTLY. HOOLEY
.LONG TERM...VALID FOR SAT...SUN...MON...TUE...WED...
FOR FRIDAY...UPPER LOW SLOWLY SHIFTS EAST AND WEAKENS. STILL
ENOUGH CYCLONIC FLOW AND LINGERING MOISTURE TO INCLUDE POPS
FRIDAY THROUGH THE DAY AND INTO THE EVENING. HIT AREAS TO THE
NORTH A LITTLE HARDER AS CLOSEST TO THE LOW AND NOT AS MUCH
DOWNSLOPE INFLUENCE. LOWERED HIGHS A COUPLE OF DEGREES WITH
CLOUDS AND SCATTERED SHOWERS AROUND. TAPERED OFF PRECIPITATION
FRIDAY EVENING BUT DID LINGER SOME LOW POPS A LITTLE FARTHER WEST
THEN THE INHERITED FORECAST SPORTED. HUMPHREY
MODELS PRETTY CONSISTENT ON THE MEDIUM RANGE FORECAST THROUGH THE
END OF THE WEEK. DRIER AIR FILTERS IN FOR THE WEEKEND ON
NORTHWEST FLOW. FLOW REMAINS NORTHWEST TO SLIGHTLY ZONAL MONDAY
THROUGH WEDNESDAY. WEAK INSTABILITY AND SOME MID LEVEL MOISTURE
COULD POP SOME ISOLATED SHOWERS AND THUNDERSTORMS IN THE
MOUNTAINS...SO INCLUDED. SHUT DOWN MOUNTAIN POPS THURSDAY AND
FRIDAY AS FLOW BECOMES MORE AMPLIFIED FROM THE NORTHWEST WITH A
STRONG UPPER RIDGE BUILDING OVER THE DESERT SOUTHWEST. SHOULD BE
ABOVE SEASONAL VALUES FOR HIGHS AND LOWS WITH RIDGE EXPANDING
EAST. NO MUCH TO CHANCE ON THE EXISTING PACKAGE OTHER THAN THE
MOUNTAIN POPS EARLY IN THE WORK WEEK MENTIONED ABOVE. HUMPHREY
&&
.AVIATION...
SCATTERED SHOWERS AND THUNDERSTORMS WILL DEVELOP ACROSS THE AREA
FROM WEST TO EAST AFTER 18Z TODAY INCREASING IN COVERAGE BY THIS
EVENING. MVFR CONDITIONS ARE POSSIBLE IN THE VICINITY OF ANY
THUNDERSTORMS DUE TO LOWER CEILINGS WITH MOUNTAINS OBSCURED AT
TIMES. MVFR CONDITIONS MAY BECOME MORE WIDESPREAD THIS EVENING AS
THUNDERSTORM ACTIVITY INCREASES. SOLUM
