AREA FORECAST DISCUSSION...UPDATED
NATIONAL WEATHER SERVICE BILLINGS MT
904 PM MDT MON JUN 2 2008
.SHORT TERM...VALID FOR TUE AND WED...
VIGOROUS UPPER LOW OVER WESTERN MONTANA WITH LOBE OF ENERGY
ROTATING AROUND LOW...AND ASSOCIATED COLD FRONT SWEEPING ACROSS
OUR REGION...ALONG WITH STRONG UPPER DIFFLUENCE ALOFT PROVIDED
GOOD ENVIRONMENT FOR THUNDERSTORM DEVELOPMENT THIS EVENING.
SEVERAL STRONG AND SEVERE THUNDERSTORMS FINALLY MERGED INTO A
LINE OF STRONG STORMS EAST OF BILLINGS THIS EVENING. STRONGEST
STORMS ARE LOCATED ON SOUTHERN PORTIONS OF LINE ACROSS BIGHORN
AND SOUTHERN ROSEBUD COUNTIES WHERE BEST COMBINATION OF UPPER
SHEAR AND UNSTABLE ENVIRONMENT ARE LOCATED. WILL MENTION ISOLATED
SEVERE THROUGH LATE EVENING IN THESE AREAS. OTHERWISE...UPDATED
POPS FOR REST OF NIGHT TO REFLECT CURRENT TRENDS. DROPPED POPS IN
WEST BACK TO SCATTERED BUT WILL KEEP NUMEROUS COVERAGE IN EAST
WITH LINE TRACKING ACROSS REST OF FORECAST AREA THERE. BT
.LONG TERM...VALID FOR THU...FRI...SAT...SUN...MON...
UNSETTLED WEATHER STILL ON TAP THROUGH MUCH OF THE EXTENDED
FORECAST WITH REASONABLE AGREEMENT ON THE LARGE SCALE FEATURES.
THE UPPER LOW THAT WILL BE MOVING THROUGH WYOMING IN THE SHORT
TERM WILL HANG AROUND INTO THURSDAY FOR CONTINUED PRECIPITATION
CHANCES AND COOL TEMPERATURES. A VERY SHORT LIVED FLAT RIDGE WILL
MOVE OVER THE AREA FRIDAY BEHIND THE LOW...WHICH WILL BE QUICKLY
REPLACED BY ANOTHER LARGE TROUGH DIGGING INTO THE WEST. THERE IS
SOME UNCERTAINTY AS TO HOW THIS NEXT TROUGH WILL EVOLVE. THE ONE
SCENARIO WOULD LEAVE THE TROUGH OFF TO THE WEST WITH A PROLONGED
PERIOD OF SOUTHWEST FLOW ALOFT...AND AFTERNOON AND EVENING
THUNDERSTORMS WITH SLIGHTLY BELOW NORMAL TEMPERATURES. THE OTHER
SCENARIO WOULD BE MORE WIDESPREAD SHOWERS AND COOLER TEMPERATURES
AS THE LOW MOVES INTO THE NORTHERN ROCKIES. BASED ON PERSISTENCE OF THE
CONTINUED PATTERN...THE LATTER SCENARIO SEEMS MORE LIKELY. HAVE
MADE JUST A FEW TWEAKS TO THE FORECAST...MAINLY TO LOWER
TEMPERATURES AND BOOST POPS SLIGHTLY TO STAY ON THE COOL AND WET
SIDE OF THE GUIDANCE. MOORE
&&
.AVIATION...
LINE OF STRONG THUNDERSTORMS WITH LOCALLY HEAVY RAIN AND HAIL
WILL MOVE ACROSS PORTIONS OF SOUTHEAST MONTANA AND NORTHEAST
WYOMING THROUGH MIDNIGHT...AND WILL AFFECT KMLS AND KSHR IN THE
LATE EVENING. OTHERWISE...ISOLATED TO SCATTERED SHOWERS AND
THUNDERSTORMS CAN BE EXPECTED THE REMAINDER OF THE NIGHT. LOCAL
MVFR CONDITIONS CAN BE EXPECTED NEAR THUNDERSTORMS WITH BRIEF
MOUNTAIN OBSCURATIONS. JUST ISOLATED STORMS POSSIBLE ON TUESDAY
AND VRF CONDITIONS. BT
