AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE MISSOULA MT 238 PM MDT MON JUN 6 2011 ...STRONG STORMS THIS EVENING FOLLOWED BY WET CONDITIONS TUESDAY IMPACTING AREA RIVERS AND STREAMS... .DISCUSSION...UNSTABLE SOUTHERLY FLOW AHEAD OF AN APPROACHING UPPER LOW IS SETTING THE STAGE FOR SCATTERED THUNDERSTORMS ACROSS NORTH CENTRAL IDAHO AND WESTERN MONTANA THE REMAINDER OF THIS AFTERNOON INTO THIS EVENING. THE POTENTIAL FOR SOME STORMS TO BECOME SEVER EXISTS MAINLY FROM THE CENTRAL CLEARWATERS THROUGH MISSOULA AND SEELEY LAKE TO POINTS SOUTH AND EAST. THERE ARE TWO MAIN THREATS FROM THESE STORMS. THE FIRST IS LARGE HAIL...HEAVY RAIN AND ERRATIC GUSTY WINDS FROM THE CLEARWATER MOUNTAINS THROUGH MISSOULA AND SEELEY LAKE TO ANACONDA AND WESTERN LEMHI COUNTY. FURTHER SOUTH AND EAST (EASTERN LEMHI COUNTY AND BUTTE/PINTLAR REGION) DRIER AIR AT THE SURFACE WILL RESULT IN DRY MICROBURST POTENTIAL (DAMAGING WINDS WITH GUSTS OVER 55 MPH) THIS AFTERNOON. AS THE UPPER LOW APPROACHES AND MOISTURE INCREASES ACROSS LEMHI COUNTY AND SOUTHWEST MONTANA...THE THREAT ACROSS SOUTHWEST MONTANA WILL TRANSITION TO HAIL AND BRIEF HEAVY RAIN. STAY TUNED FOR A POTENTIAL SEVERE WEATHER WATCH FOR THIS EVENING. AFTER MIDNIGHT THROUGH TUESDAY AFTERNOON...THE UPPER LOW WILL SWING NORTH THROUGH EASTERN IDAHO AND SOUTH CENTRAL MONTANA. A MID LEVEL CIRCULATION OVER SOUTHWEST MONTANA IS IN A GOOD LOCATION TO BRING WIDESPREAD HEAVY RAIN FALL TO PORTION OF NORTH CENTRAL IDAHO AND WEST CENTRAL MONTANA UP ALONG THE CONTINENTAL DIVIDE. THIS IS THE SAME LOCATION THAT RECEIVED AMPLE MOISTURE LATE LAST WEEK WITH THE MAIN DIFFERENCE BEING SNOW LEVELS WILL BE QUITE A BIT HIGHER (AROUND 10000 FEET) WHICH WILL RESULT IN RAIN ATOP OF SNOW. THE PAST WEEKENDS VERY HOT TEMPERATURES ALLOWED UPPER LEVEL SNOW PACK TO COMPACT AND INCREASE MOISTURE CONTENT. RAIN WILL INCREASE THE MOISTURE CONTENT FURTHER...AND IT WILL EVENTUALLY WILL REACH SATURATION AND THE RAIN WILL RUN OFF. THIS SCENARIO WILL RESULT IN HYDROLOGIC CONCERNS FOR AREA RIVERS AND STREAMS. PLEASE SEE WWW.WEATHER.GOV/MISSOULA FOR LATEST HYDROLOGIC HEADLINES. ANOTHER PACIFIC WEATHER SYSTEM WILL MOVE IN FROM THE BRITISH COLUMBIA COAST TUESDAY NIGHT. THIS SYSTEM IS BRINGING ANOTHER ROUND OF AMPLE PRECIPITATION...BUT NOT AS MUCH AS TONIGHTS SYSTEM. THE TRACK OF THIS NEXT SYSTEM WILL BRING THE MAJORITY OF THE PRECIPITATION TO NORTHWEST MONTANA. WITH ITS ORIGIN FURTHER NORTH...THE AIRMASS WILL BE COOLER AND SNOW LEVELS LOWER. THIS WILL DECREASE THE RUN OFF POTENTIAL THROUGH WEDNESDAY. WEDNESDAY NIGHT THROUGH FRIDAY...THE UPPER LOW WILL MOVE INTO SOUTHWEST MONTANA KEEPING THE CHANCE OF PRECIPITATION HIGH. THIS WILL ADD MORE WATER TO STREAMS AND RIVERS...KEEPING THEM RUNNING HIGH. ON SATURDAY...WESTERN MONTANA AND NORTH CENTRAL IDAHO WILL GET A BRIEF BREAK BEFORE THE NEXT TROUGH OF LOW PRESSURE MOVES SOUTH OUT OF CANADA AND KEEPS A CHANCE OF PRECIPITATION OVER THE REGION FOR THE REST OF THE EXTENDED FORECAST PERIOD. && .AVIATION...SCATTERED TO WIDESPREAD SHOWERS WILL AFFECT THE NORTHERN ROCKIES TODAY. PLENTY OF DAYTIME HEATING AND INSTABILITY ACROSS THE REGION WILL INTRODUCE THUNDERSTORM POTENTIAL AT ALL TERMINALS THIS AFTERNOON INTO THIS EVENING. PERIODS OF HEAVY RAIN AND SMALL HAIL MAY ACCOMPANY THE THUNDERSTORMS THIS AFTERNOON...MAINLY IMPACTING KMSO...KBTM...AND KSMN UNTIL 07/03Z. GUSTY AND ERRATIC WINDS WILL BE A FREQUENT FEATURE WITH THE THUNDERSTORMS AFFECTING KBTM AND KSMN. MORE ISOLATED STORMS CAN BE EXPECTED AT KGPI. BEYOND 07/03Z...THUNDERSTORM ACTIVITY SHOULD LESSEN...ALLOWING FOR MORE PERSISTENT RAIN SHOWERS TO AFFECT THE ENTIRE NORTHERN ROCKIES. CLOUD DECKS WILL THEN LOWER TO MVFR LEVELS THROUGH TUESDAY. && NOTE: FLOOD WATCHES...WARNINGS AND ADVISORIES WILL NOT BE LISTED BELOW. .MSO WATCHES/WARNINGS/ADVISORIES... MT...NONE.
