301 PM MDT MON JUL 13 2009
.SHORT TERM...VALID FOR TUE AND WED...
LINE OF STRONGER THUNDERSTORMS CURRENTLY PUSHING INTO THE WESTERN
DAKOTAS THIS AFTERNOON. STRONGER CELLS STARTED TO DEVELOP JUST IN
CARTER COUNTY AS IT MOVED INTO THE DAKOTAS. CONVECTIONS STARTING
TO FIRE OUT ACROSS WESTERN AND CENTRAL MONTANA AS WELL AS OVER
THE SOUTHWEST MOUNTAINS AND OVER THE PRYOR AND BIG HORN
MOUNTAINS. EXPECT THIS DEVELOPMENT TO CONTINUE THROUGH THE
AFTERNOON AS DAYTIME HEATING KICKS IN. AN AREA FROM RED LODGE TO
BILLINGS MAY BE LIMITED FOR CONVECTION THIS AFTERNOON AS SOME
DRIER AIR DOES LOOK TO BE WORKING IN. CONTINUED MENTION OF SEVERE
STILL LOOKS GOOD ACROSS THE ENTIRE AREA FOR THIS AFTERNOON AND
CONTINUING OUT EAST TONIGHT. UPPER DIFFLUENCE ALOFT COMBINED WITH
GOOD MOISTURE...CAPES AND INSTABILITY SHOULD KEEP THINGS ACTIVE
THROUGH THE NIGHT. STRONG UPPER LEVEL TROUGH WILL CONTINUE TO
PUSH EAST TONIGHT AND BE CENTERED OVER THE EASTERN ZONES BY
TUESDAY MORNING. DO THINK THERE WILL BE A BREAK IN THE PRECIP
SOMEWHERE AS THE AXIS SHIFTS ACROSS BUT DO EXPECT SOME WRAPAROUND
PRECIP FOR MUCH OF THE AREA ON TUESDAY AS THE LOW PUSHES INTO THE
DAKOTAS. TUESDAY WILL BE MUCH COOLER BEHIND THE FRONT AND BELOW
NORMAL FOR THIS TIME OF YEAR. UPPER LEVEL PATTERN STAYS IN
NORTHWEST FLOW INTO WEDNESDAY. DO NOT EXPECT MUCH FOR PRECIP ON
WEDNESDAY BUT DID KEEP SOME DIURNAL POPS IN FOR SOME ISOLATED
AFTERNOON AND EVENING PRECIPITATION. WEDNESDAY WILL ALSO CONTINUE
TO BE COOLER THAN NORMAL. SOLUM
.LONG TERM...VALID FOR THU...FRI...SAT...SUN...MON...
MUCH QUIETER PATTERN AS WE LOOK TOWARD THE EXTENDED FORECAST. ONLY
MINOR ADJUSTMENTS TO GOING FORECAST...AND MAINLY ADJUSTMENTS IN
TEMPERATURES. UPPER HEIGHTS EXPECTED TO BUILD ACROSS THE ROCKIES
INTO NEXT WEEKEND. PRECIP CHANCES APPEAR MINIMAL INTO AT LEAST
SATURDAY...ALTHOUGH MIGHT NOT NEED MORE THAN VERY WEAK ENERGY
TOPPING THE RIDGE TO DEVELOP A FEW STORMS. FOR THE MOST PART...LOW
PRECIP CHANCES ARE CONFINED TO THE MOUNTAINS. SUNDAY APPEARS TO BE
BEST CHANCES FOR STORMS AS A STRONGER SHORT WAVE TRIES TO BREAK
DOWN THE RIDGE. OVERALL...ANTICIPATING NEAR TO ABOVE SEASONAL
TEMPERATURES THROUGH THE PERIOD...WITH HIGHS CLOSE TO 90 MOST
AREAS. COOLEST TEMPEATURES LIKELY SUNDAY INTO MONDAY WITH THE
INCREASED PRECIP CHANCES. FRIEDERS
&&
.AVIATION...
THUNDERSTORMS WILL BE ON THE INCREASE ACROSS THE REGION INTO THE
EVENING HOURS WITH CHANCES CONTINUING OVERNIGHT. SOME OF THESE
STORMS WILL LIKELY TURN SEVERE WITH LARGE HAIL...WINDS IN EXCESS
OF 50 KTS AND VERY HEAVY RAINFALL THROUGH THIS EVENING. VFR
CONDITIONS WILL PREVAIL...ALTHOUGH THESE STRONGER STORMS WILL
LIKELY PRODUCE LOCAL IFR CONDITIONS. FRIEDERS
