AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE BILLINGS MT
259 PM MDT WED AUG 16 2006
.SHORT TERM...VALID FOR THU AND FRI...
BROAD TROUGH OVER THE PACIFIC NORTHWEST WILL MOVE EAST OVERNIGHT
AND DURING THE DAY ON FRIDAY. SEVERAL UPPER LEVEL DISTURBANCES
WILL MOVE OUT AHEAD OF THIS TROUGH THIS EVENING AND OVERNIGHT
BRINGING A CHANCE FOR THUNDERSTORMS. STORMS HAVE ALREADY
DEVELOPED OVER WESTERN MONTANA AND IDAHO AND THIS IS WHERE THE
GREATEST POTENTIAL FOR SEVERE STORMS WILL BE LOCATED.
HOWEVER..THUNDERSTORMS NOW FIRING OVER NORTHWEST WYOMING AND THE
BEARTOOTH MOUNTAINS. STORMS WILL BE A MIX OF WET AND DRY BUT
BECOME MORE WET AS THE NIGHT PROGRESSES. MAIN THREAT FROM STORMS
WILL BE GUSTY WINDS AGAIN BUT A FEW MAY CONTAIN HAIL. CAN NOT
RULE OUT AN ISOLATED SEVERE STORM ESPECIALLY WITH WIND THREAT.
HOWEVER...SEVERE THREAT DOES NOT LOOK WIDESPREAD ENOUGH TO
MENTION IN ZONES. STRONGEST PART OF UPPER WAVE LOOKS TO STAY TO
OUR WEST AND NORTHWEST OVERNIGHT. BEST CHANCES FOR THUNDERSTORMS
WILL BE ACROSS THE CENTRAL AND WESTERN ZONES WITH ISOLATED
CHANCES OUT EAST.
A STRONG COLD FRONT WILL SWEEP ACROSS THE FORECAST AREA LATE
TONIGHT. THIS WILL USHER IN GUSTY NORTH TO NORTHEAST WINDS
TONIGHT THROUGH THURSDAY NIGHT. TROUGH MOVES ACROSS THE FORECAST
AREA DURING THE AFTERNOON BRINGING A BETTER CHANCE FOR SHOWERS
AND THUNDERSTORMS. STRONG SURFACE LOW DEVELOPS OVER NORTHEAST
WYOMING DURING THE AFTERNOON AND REMAINS STATIONARY THROUGH
THURSDAY NIGHT. STRONG BAROCLINIC ZONES SETS UP FROM THE WESTERN
DAKOTAS TO WESTERN WYOMING. AS A RESULT...HAVE DECIDED TO
INCREASE POPS INTO THE LIKELY CATEGORY FOR ALL AREAS EXCEPT THE
SOUTHEAST FOR THURSDAY EVENING. SIGNIFICANT SHEAR ALONG WITH
CAPES OF 1300-1400J/KG ACROSS THE EXTREME EAST/SOUTHEAST ZONES
EXISTS DURING THE AFTERNOON. WILL THEREFORE MENTION SEVERE WORDING
IN THOSE ZONES AS HAIL AND DAMAGING WINDS A POSSIBILITY.
TEMPERATURES THURSDAY WILL BE A GOOD 5 TO 10 DEGREES COOLER THAN
TODAY WITH EVEN COOLER READINGS FOR FRIDAY. SYSTEM BEGINS TO EXIT
THE AREA DURING THE DAY FRIDAY BUT WILL CONTINUE WITH A SLIGHT
CHANCE FOR A SHOWER OR THUNDERSTORM. HOOLEY
.LONG TERM...VALID FOR SAT...SUN...MON...TUE...WED...
CONTINUED THE DRY EXTENDED FORECAST. MODELS WERE IN GENERAL
AGREEMENT WITH PATTERN THROUGH TUE...THEN HAD DIFFICULTY RESOLVING
POSITION OF PACIFIC TROUGH ON WED. GENERALLY ZONAL FLOW WITH WEAK
SHORTWAVES WILL BE OVER THE REGION SAT AND SUN. AIRMASS PROGGED TO
BE DRY SO NO POPS NEEDED. UPPER RIDGING WILL BUILD INTO THE AREA
FOR MON AND TUE. HOWEVER...BOTH GFS AND ECMWF HAD A SHORTWAVE
OVER ALBERTA/SASKATCHEWAN ON TUE WHICH MAY AFFECT THE AREA AS IT
MOVES SE. WILL WAIT TO SEE HOW THIS SITUATION EVOLVES IN FUTURE
RUNS BEFORE MAKING ANY CHANGES. WILL ALSO NEED TO WATCH EVOLUTION
OF PACIFIC TROUGH FOR THE MIDDLE OF NEXT WEEK. FORECAST FEATURED A
WARMING TREND. ONLY TEMPERATURE ADJUSTMENTS WERE TO NUDGE MAXES UP
A LITTLE ON SAT AND TUE. ARTHUR

.AVIATION...
ISOLATED TO SCATTERED SHOWERS AND THUNDERSTORMS WILL OVERSPREAD
THE ROUTES FROM SW TO NE THIS AFTERNOON AND EVENING. PRECIPITATION
WILL BE ACCOMPANIED BY MVFR CONDITIONS WITH ISOLATED IFR POSSIBLE.
ISOLATED TO SCATTERED SHOWERS AND THUNDERSTORMS WILL AFFECT THE AREA
FROM KLVM WEST AND NORTH OF KBIL TO KMLS LATE TONIGHT AND THU
MORNING. EXPECT MVFR CONDITIONS WITH THE PRECIPITATION OTHERWISE
VFR WILL PREVAIL OVER THE ROUTES. SCATTERED SHOWERS AND
THUNDERSTORMS WILL REDEVELOP ACROSS THE AREA THU AFTERNOON AND
BECOME MORE WIDESPREAD THU EVENING. MVFR AND ISOLATED IFR WILL
ACCOMPANY THE PRECIPITATION. ARTHUR
