WEATHER.GOV/GLASGOWWhat forecasters said that day
The local office's own words before this severe thunderstorm warning went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.
NWS Glasgow, MT wrote its last area forecast discussion before this severe thunderstorm warning went out at Jul 11, 2:00 PM MDT, 2 hours 43 minutes earlier.
Area forecast discussion, Jul 11, 2:00 PM MDT, 2 hours 43 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE GLASGOW MT 200 PM MDT WED JUL 11 2012 .SHORT TERM...FOR NORTHEAST MONTANA...TONIGHT THROUGH FRIDAY... WEAK LOW PRESSURE OVER THE MONDAK REGION WILL PROVIDE ENOUGH INSTABILITY FOR SOME THUNDERSTORMS TONIGHT. MULTICELLULAR STORMS ARE STILL THE MAIN EXPECTATION WITH SOME GUSTY WINDS AND BRIEF HEAVY RAIN POSSIBLE. COULD SEE A FEW STORMS GUST TO 60 MPH OR SO BUT OTHERWISE JUST EXPECTING A LOT OF CELLS POPPING UP AND LASTING FOR AWHILE, DISSIPATING AND POPPING UP AGAIN. LOW PRESSURE MOVES EASTWARD AND HIGH PRESSURE STARTS PUSHING INTO THE AREA WITH A FAIRLY STABLE ATMOSPHERE FOR THE NEXT TWO DAYS. MODELS ARE IN GOOD AGREEMENT WITH THE SYSTEM COMING THROUGH THIS AFTERNOON AND EVENING AS WELL AS WITH TEMPS AND WINDS THROUGH FRIDAY. FRANSEN .LONG TERM...FRIDAY NIGHT THROUGH WEDNESDAY... THE LONG TERM HAS NOT CHANGED ALL THAT MUCH...WITH A PAIR OF UPPER LOWS SITTING OVER THE COLUMBIA RIVER VALLEY REGION THROUGH THE WEEKEND AND INTO THE FIRST PART OF THE WORK WEEK. INITIALLY ON SATURDAY...THE UPPER RIDGE AHEAD OF THE APPROACHING LOWS BUILDS A BIT BEFORE PROGRESSING EASTWARD AS THE FIRST TROUGH DIGS OVER THE PACIFIC NORTHWEST. THIS SHOULD KEEP HIGHS IN THE 90S TO START THE WEEKEND. BY SUNDAY AFTERNOON...SOUTHWEST FLOW SITS IN ALOFT...AND REMAINS UNTIL THE END OF THE PERIOD AS THE NEXT UPPER LOW WORKS ITS WAY SOUTH FROM BRITISH COLUMBIA. THIS SHOULD BRING A FEW SHORTWAVES THROUGH THE FLOW AND ENABLE THE CHANCE FOR THUNDERSTORMS DAILY FOR NEXT WEEK. THE CORRESPONDING TROUGH SHOULD ALSO BRING COOLER TEMPERATURES TO THE REGION...WITH HIGHS MOSTLY IN THE 80S FOR THE CWA THROUGH POSSIBLY WEDNESDAY. DURING THE THURSDAY AND FRIDAY TIMEFRAME NEXT WEEK...THE UPPER TROUGH AND CLOSED LOW APPEAR TO WEAKEN SLIGHTLY AND FINALLY MIGRATE OUT OF THE PACIFIC NORTHWEST. AS THE UPPER TROUGH MOVES THROUGH THE NORTHERN HIGH PLAINS...BROAD SOUTHWEST FLOW ALOFT WILL COME TO AN END. ANOTHER UPPER RIDGE APPEARS TO BUILD IN BEHIND THE TROUGH...AND ABOVE AVERAGE SUMMER TEMPERATURES WILL RETURN TO THE REGION. BARNWELL PREVIOUS LONG TERM DISCUSSION...THE UPPER LEVEL RIDGE REMAINS OVER NORTHEAST MONTANA TO BEGIN THE EXTENDED PERIOD FRIDAY EVENING. HOWEVER MODELS SHOW A CLOSED UPPER LOW PARKED OVER WESTERN WASHINGTON AT 00Z. THE ASSOCIATED UPPER TROUGH SENDS DISTURBANCES INTO THE NORTHERN ROCKIES AND THE ADJACENT NORTHERN PLAINS ON SATURDAY. EXPECT ANOTHER ROUND OF THUNDERSTORMS...BUT WITH SLIGHTLY COOLER TEMPERATURES FROM THE DAY BEFORE. SATURDAY NIGHT ANOTHER CLOSED LOW DROPS SOUTH INTO THE CANADIAN ROCKIES ADDING ENERGY TO THE TROUGH. THIS INITIATES AN UNSETTLED PERIOD THROUGH MONDAY NIGHT WITH A DAILY CHANCE FOR THUNDERSTORMS AND NEAR NORMAL TEMPERATURES. TUESDAY AND BEYOND...THE CLOSED LOW PARKED OVER WESTERN WASHINGTON BEGINS TO WANDER SOUTH DOWN THE WEST COAST. THIS WILL ALLOW THE RIDGE TO BUILD BACK INTO MONTANA...ONCE AGAIN BRINGING IN THE MUCH WARMER TEMPERATURES...AND ISOLATED THUNDERSTORMS. SCT && .AVIATION... AN UPPER LEVEL DISTURBANCE SWEEPING ACROSS NORTHEAST MONTANA WILL MEET MORE HEAT GENERATED UNSTABLE AIR...BRINGING ANOTHER ROUND OF AFTERNOON AND EVENING THUNDERSTORMS. A FEW MAY BE SEVERE STRENGTH WITH STRONG WINDS AND HEAVY RAIN POSSIBLE INTO THE EVENING. OTHERWISE EXPECT NORTHWEST WINDS AROUND 10 KNOTS THROUGH THE EVENING HOURS BEFORE LIGHT AND VARIABLE WINDS MOVE IN DURING THE OVERNIGHT HOURS. BARNWELL && .GLASGOW WATCHES/WARNINGS/ADVISORIES...
