230 PM MDT SUN JUN 4 2006

.DISCUSSION...
A PACIFIC COOL FRONT IS QUICKLY APPROACHING THE REGION THIS
AFTERNOON...AND THIS FRONTAL PASSAGE WILL CREATE AN ACTIVE WEATHER
NIGHT ACROSS CENTRAL AND EASTERN MONTANA.

SHOWERS AND THUNDERSTORMS ARE MOVING THROUGH WESTERN MONTANA AT
2 PM...AND THESE STORMS WILL MOVE ACROSS SOUTHWEST AND CENTRAL
MONTANA DURING THE REMAINDER OF THE AFTERNOON AND THROUGH THE
EVENING HOURS. THE STRONGER STORMS WILL BE CAPABLE OF PRODUCING
DAMAGING WIND GUSTS AND HAIL. CURRENT THUNDERSTORM WATCH REMAINS IN
EFFECT FOR SOUTHWEST AND A PORTION OF CENTRAL MONTANA...WHILE A NEW
THUNDERSTORM WATCH IS LIKELY TO BE ISSUED LATER THIS AFTERNOON OR
EARLY THIS EVENING FOR THE EASTERN PORTIONS OF CENTRAL MONTANA AND
PARTS OF EASTERN MONTANA. EXPECT THUNDERSTORMS TO GRADUALLY COME TO
AND END FROM WEST TO EAST LATE THIS EVENING. OVERNIGHT LOWS WILL
COOL TOWARDS FORECASTED LOWS AFTER MIDNIGHT...WHEN SOME CLEARING
TAKES PLACE.

FOR MONDAY THROUGH TUESDAY NIGHT...A FAIRLY QUIET WEATHER PATTERN IS
EXPECTED TO RESIDE OVER THE REGION DURING THIS TIME. A NEW UPPER
LEVEL RIDGE WILL BUILD OVER CENTRAL MONTANA. THIS RIDGE WILL ALLOW
AFTERNOON TEMPERATURES TO SLOWLY WARM BACKUP INTO THE MID 80S...(OR
CLOSE TO 15 DEGREES ABOVE NORMAL) BY TUESDAY. OVERNIGHT LOWS WILL
COOL NICELY DO TO DRY AIR IN PLACE. RIGHT NOW THE AIRMASS LOOKS TO
STABLE AND DRY FOR ANY THUNDERSTORM ACTIVITY...BUT A VERY ISOLATED
MOUNTAIN SHOWER CAN NOT BE RULED OUT...ESPECIALLY TOWARDS MID WEAK.
BRUSDA

TUESDAY NIGHT THROUGH FRIDAY NIGHT...UPPER LEVEL RIDGE TO BUILD OVER
THE AREA THROUGH THURSDAY WITH AN UPPER LEVEL TROF DIGGING ALONG THE
PACIFIC COAST. RETURN TO A MOIST SOUTHWESTERLY FLOW ALOFT THURSDAY
NIGHT THROUGH FRIDAY NIGHT WITH AN INCREASE IN MOISTURE AND CHANCE
OF PRECIPITATION. WARM TEMPERATURES WEDNESDAY AND THURSDAY WITH A
WET AND COOLING TREND FOR FRIDAY. CAMP

SATURDAY THROUGH SUNDAY...MODELS IN FAIR AGREEMENT DURING THIS
PERIOD. AN UPPER LEVEL TROUGH MOVES ACROSS THE FORECAST AREA
SATURDAY. MOST OF THE ENERGY AND MOISTURE WITH THIS SYSTEM GOES
NORTH OF THE AREA. PARTLY TO MOSTLY CLOUDY SKIES ARE
EXPECTED...WITH ISOLATED TO SCATTERED SHOWERS AND THUNDERSTORMS FOR
MOST AREAS. WEAK RIDGING ALOFT SUNDAY DRIES ALL BUT THE WESTERN
MOUNTAINS WHERE A WESTERLY FLOW ALOFT RESULTS IN SCATTERED SHOWERS
AND THUNDERSTORMS. TEMPERATURES COOL A FEW DEGREES BUT REMAIN NEAR
SEASONAL AVERAGES. EK

.AVIATION...
UPDATED 1803Z
CENTRAL AND SOUTHWEST MONTANA IS UNDER A SEVERE THUNDERSTORM WATCH
UNTIL 00Z. AN UPPER LEVEL SHORTWAVE IS MOVING ACROSS WESTERN MONTANA

SCATTERED THUNDERSTORMS WILL DEVELOP WITH THE POTENTIAL OF
STRONG...DAMAGING WINDS. GUSTS TO 60KTS ARE POSSIBLE NEAR THESE
THUNDERSTORMS. MVFR CONDITIONS MAY DEVELOP NEAR THUNDERSTORMS BUT
VFR CONDITIONS WILL PREVAIL ELSEWHERE DURING THE NEXT 24 HOURS.
