Area forecast discussion, Jun 17, 3:26 PM MDT, 3 hours 4 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GLASGOW MT
326 PM MDT FRI JUN 17 2011

.SHORT TERM...FOR NORTHEAST MONTANA...TONIGHT THROUGH SUNDAY...
UPPER LOW COMPLEX HAS DEVELOPED A NEW CLOSED CIRCULATION OVER NE
MT...CENTERED OVER ROOSEVELT COUNTY AS SEEN ON THE RADAR AND
SATELLITE LOOPS. THIS FORECAST BY MODELS...AND IT HAS SLOWED DOWN
ITS NORTHWARD MOVEMENT SOMEWHAT. SURFACE LOW CENTER IS OVER
PLENTYWOOD. THIS IS ALL CONNECTED TO THE WEAKENING UPPER LOW OVER
AB. WITH LOW LEVEL COOLING AND INCREASING STABILITY. PRECIP HAS
TRANSITIONED INTO MAINLY A STEADY RAIN EVENT WITH NO LIGHTNING
STRIKES FOR THE FEW COUPLE OF HOURS. WILL ADJUST THE FLASH FLOOD WATCH
TO ACCOUNT FOR THIS...AS THERE HAS BEEN FLASH FLOODING IN THE
AREA.

RAIN SHOULD END FROM S TO N THIS EVENING. THE E MT PART OF THE
CLOSED UPPER LOW DRIFTS NW AND STALLS OVER S SK/S AB. THE AIRMASS
OVER E MT REMAINS VERY MOIST AND WITH GENERAL TROUGHY CONDITION'S
ALOFT. THERE IS SOME WARMING OF LOWER LEVELS DUE TO MORNING
SUNSHINE SAT...AND LIGHT S FLOW. THIS DESTABILIZES THE AIRMASS
AGAIN. THEREFORE EXPECTING CONVECTIVE TEMPS TO BE REACHED BY NOON
WITH RATHER ACTIVE AND MOIST SCATTERED THUNDERSTORMS DEV LOPING.

SIMILAR TO PAST OCCURRENCES OF LATE THE STALLED UPPER LOW TO OUR N
INTERACTS WITH ANOTHER UPPER LOW MOVING INTO THE PACIFIC NW WHICH
DRIVES THIS ENERGY INTO E MT SUNDAY. PRECIP WATER RISES TO 1.2
INCHES. LIFTED INDEXES IN OUR E AS AS LOW AS -8...WITH CAPES
OVER 2000 J/KG. HOWEVER SHEAR PROFILE VERY POOR FOR SEVERE
WEATHER. THE RESULT WILL BE A LOT OF VERY STRONG AND VERY MOIST
THUNDERSTORMS WITH SMALL HAIL...AND THIS WILL BE A CONCERN FOR
HEAVY AMOUNTS OF RAINFALL AGAIN. MAV MOS LOOKS TOO WARM...PREFER
COOLER HIGHS OF MET. SIMONSEN

.LONG TERM...SUNDAY NIGHT THROUGH FRIDAY...
COOL AND WET PATTERN EXPECTED TO CONTINUE THROUGH NEXT WEEK.
COMPLEX UPPER LOW LIFTING ACROSS EASTERN MONTANA TODAY LIFTS INTO
CANADA AND ANOTHER LOW IS EXPECTED TO ROTATE AROUND IT THROUGH
MONTANA OVER THE WEEKEND. THIS SECOND LOW WILL PUSH INTO THE
CENTRAL PLAINS AT START OF THE WORK WEEK WITH ANOTHER AREA OF
SIGNIFICANT RAIN POSSIBLE OVER EASTERN MONTANA ON MONDAY. SLIGHT
RIDGE DEVELOPS BEHIND THIS LOW FOR POSSIBLE DRY WEATHER MID WEEK
BUT RAIN WILL RETURN LATE IN THE WEEK AS ANOTHER TROF PUSHES INTO
WESTERN CANADA OR THE PACIFIC NORTHWEST. EBERT

PREVIOUS LONG TERM DISCUSSION...SUNDAY NIGHT THROUGH SATURDAY...
THE LONG TERM FORECAST PERIOD BEGINS IN THE MIDDLE OF A VERY WET
PATTERN WHICH WE MAY ONLY GET A BRIEF BREAK FROM IN THE MIDDLE OF
NEXT WEEK. EXPECT THE SHOWERS AND THUNDERSTORMS TO CONTINUE
THROUGH TUESDAY AFTERNOON BEFORE WE GET ANY BREAK IN THE WEATHER
PATTERN.

THE CWA IS IN BETWEEN TO UPPER LOWS ONE PASSING TO THE THE SOUTH
MONDAY AND TUESDAY AND ONE BEING PULLED TO THE NORTHWEST AND
WRAPPED INTO A LARGER UPPER LOW OVER THE GULF OF ALASKA MONDAY
AFTERNOON. AN UPPER LEVEL RIDGE BUILDING IN FROM THE WEST AND
BEGIN DRYING THINGS OUT TUESDAY NIGHT THROUGH THURSDAY.
TEMPERATURES WILL ALSO FINALLY FEEL WARMER DURING THIS PERIOD OF
TIME.

MODELS START TO DISAGREE AS THE AFOREMENTIONED UPPER LOW OVER THE
GULF OF ALASKA SINKS OVER THE PACIFIC NORTHWEST ALL MODELS SHOW
THIS HAPPENING THURSDAY AFTERNOON/EVENING TIME FRAME. AFTER THIS
HOWEVER THEY DISAGREE ON WHAT HAPPEN NEXT...AS THE MODELS ARE ALL
OVER THE PLACE WITH WHERE THIS NEXT LARGE COMPLEX UPPER LOW MOVES
AND HOW IT EFFECTS THE WEATHER OF EASTERN MONTANA. SO KEPT THE
FORECAST AS CLOSE TO CLIMO AS POSSIBLE  STARTING THURSDAY NIGHT
THROUGH SATURDAY MORNING. RSMITH

&&

.AVIATION...
RAIN WILL BE LIFTING NORTH OF THE REGION THIS EVENING WITH
CONDITIONS IMPROVING AT ALL TERMINALS. UNTIL THEN MVFR WITH
OCCASIONAL IFR CONDITIONS WILL PERSIST...MAINLY AT KGGW AND KOLF.

&&

.HYDROLOGY...
EXTENSIVE FLOODING CONTINUES ON THE MILK RIVER FROM NEAR HINSDALE
THROUGH NASHUA. FLUCTUATIONS ARE EXPECTED IN RIVER LEVELS THROUGH
NEXT WEEKEND AS RUNOFF FROM RECENT RAINS MOVES INTO AND DOWN THE
RIVER. HIGH WATER ALSO WILL CONTINUE ON STREAMS FEEDING INTO THE
MILK RIVER FROM THE SOUTH INCLUDING PEOPLES CREEK...BEAVER CREEK
AND WILLOW CREEK. TRIPLE CREEK RESERVOIR IN S VALLEY COUNTY IS IN
DANGER OF FAILING...WHICH EMPTIES INTO LONE TREE CREEK...THEN INTO
WILLOW CREEK.

FLOODING ALSO CONTINUES ALONG THE MUSSELSHELL RIVER AND MANY
CREEKS ACROSS PETROLEUM COUNTY.

WATER RELEASES WILL CONTINUE FROM FORT PECK DAM AT AROUND 65K
CFS. THE MISSOURI RIVER FROM BELOW THE DAM TO THE NORTH DAKOTA
BORDER WILL CONTINUE TO REMAIN HIGH DUE TO THESE RELEASES COMBINED
WITH THE WATER FLOWING FROM THE MILK RIVER. LITTLE CHANGE IN
RIVER LEVEL IS EXPECTED OVER THE WEEKEND.

MULTIPLE PERIODS OF VARYING DEGREES OF RAINFALL THROUGH THE
WEEKEND AND INTO NEXT WEEK. WIDESPREAD RAIN OF ONE TO TWO INCHES
HAS OCCURRED ACROSS EASTERN MONTANA TODAY WITH RAIN LINGERING INTO
THE EVENING OVER THE FAR NORTHEAST. THE FLASH FLOOD WATCH WILL
CONTINUE INTO THE EVENING..

THE WEATHER PATTERN REMAINS SOMEWHAT ACTIVE WITH PERIODS OF
RAIN...SOMETIMES LOCALLY HEAVY...THROUGH EARLY NEXT WEEK. WITH
WIDESPREAD SATURATED GROUND FROM RECENT RAINS...FLASH FLOODING
WILL BE POSSIBLE FROM ANY HEAVY RAIN STORM THAT DEVELOPS.

&&

.CLIMATE...
GLASGOW HAS NOT YET HAD AN 80 DEGREE TEMPERATURE YET THIS
YEAR...WHICH IS NOW A RECORD FOR BEING SO LATE. THE PREVIOUS
RECORD FOR LATEST FIRST 80 DEGREE WAS JUN 16TH 1899. WE CAME VERY
CLOSE WITH 79 FOR A HIGH ON JUN 5TH...BUT THE NEXT CHANCE OF AN 80
DEGREE TEMPERATURE WON'T BE UNTIL AT LEAST LATE NEXT WEEK.
