AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GLASGOW MT
839 PM MDT MON AUG 13 2012

.SHORT TERM...FOR NORTHEAST MONTANA...TONIGHT THROUGH WEDNESDAY...
THUNDERSTORM ACTIVITY OVER THE SE ZONES SHOULD BE OUT OF THE CWA BY
ABOUT 10 PM. CLEARING IS OCCURRING ACROSS THE AREA IN ITS WAKE AND
SHOULD ALLOW TEMPS TO COOL CLOSE TO THEIR RESPECTIVE DEWPOINTS
ESPECIALLY IN THE SE ZONES. THEREFORE ADDED MENTION OF PATCHY FOR
FOR LATER TONIGHT AND TUESDAY MORNING. ALSO LOWERED TEMPS AS THEY
WERE GETTING CLOSE TO THEIR RESPECTIVE MINIMUM FORECAST. OTHER
CHANGES WERE MINOR. JAMBA

PREVIOUS DISCUSSION...
QUASI MCS MOVING ACROSS NORTHEAST MONTANA TODAY HAS KEPT WARM
FRONT FROM LIFTING NORTHWARD. THIS HAS RESULTED IN MUCH COOLER
TEMPERATURES FOR MUCH OF THE REGION THIS AFTERNOON. STORM COMPLEX
WILL CONTINUE ITS SLOW MARCH SOUTHEASTWARD THROUGH THE EVENING AND
MAY HAVE SOME LINGERING SHOWERS IN THE NORTHEAST CORNER OF THE
STATE DURING THE EARLY MORNING HOURS.

FORECAST FOR TUESDAY CONTINUES TO BE PROBLEMATIC. THE MAIN FEATURE
IS SHORTWAVE DIVING ACROSS WESTERN CANADA WHICH WILL PUSH A STRONG
COLD FRONT INTO NORTHERN MONTANA TUESDAY EVENING. FLOW EXPECTED TO
BUCKLE AHEAD OF THIS WAVE...LIFTING WARM FRONT ACROSS MOST OF
EASTERN MONTANA TUESDAY AFTERNOON...AND DEVELOPING SOME DRYING
DOWNSLOPE WINDS MAINLY IN THE SOUTHWEST ZONES. WINDS AND HUMIDITY
WILL BE IN RANGE TO PRODUCE CRITICAL FIRE WEATHER CONDITIONS. FOR
NOW WILL LEAVE FIRE WEATHER WATCH IN PLACE TO ALLOW LATER SHIFT TO
ASSESS IMPACT OF TODAYS STORMS.

FRONT BLOWS THROUGH THE REGION WEDNESDAY MORNING WITH TEMPERATURES
FALLING SHARPLY. STRONG CAA BEHIND THE FRONT AND TIGHT GRADIENT
WILL PRODUCE GUSTY NORTH WINDS AND WILL LIKELY PRODUCE LAKE WIND
ADVISORY CONDITIONS FOR MOST OF WEDNESDAY. MOST OF THE
PRECIPITATION IS EXPECTED TO OCCUR IN THE VICINITY OF THE 700 MB
FRONT AS IT PUSHES SOUTH DURING THE MORNING HOURS ON WEDNESDAY.
THE INSTABILITY WITH THE CAA WILL LIKELY RESULT IN SHOWERS
CONTINUING INTO THE AFTERNOON. EBERT

.LONG TERM...WEDNESDAY NIGHT THROUGH MONDAY...
THE QUIET PATTERN LOOKS TO REMAIN UNCHANGED IN THE LONG TERM.
STRONG NORTHWEST FLOW ALOFT LINGERS FOR A FEW DAYS AS THE LARGE
UPPER RIDGE BUILDS OVER THE WEST. AS THE RIDGE SLIDES TO THE
EAST...A FEW SHORTWAVE TROUGHS WEAKEN THE RIDGE SUNDAY AND INTO
MONDAY. OTHERWISE...THE PREVIOUS FORECAST LOOKS GOOD.

ADDITIONAL SHORTWAVES LOOK TO AFFECT THE REGION BEGINNING ON
TUESDAY FOR THE GFS...AND WEDNESDAY FOR THE ECMWF. BOTH MODELS
AGREE THAT A STRONGER SHORTWAVE MOVES IN AFTER THE CURRENT PERIOD
FOR THE LATE WEDNESDAY INTO THURSDAY TIMEFRAME BEFORE A LARGER
UPPER TROUGH SLIDES INTO ALBERTA. THIS SHOULD BRING THE DRIER
CONDITIONS TO AN END AND SOME WELCOMED PRECIP BACK TO THE REGION. BARNWELL

PREVIOUS LONG TERM DISCUSSION...THE EXTENDED FORECAST BEGINS WITH
THE STRONG FALL LIKE COLD FRONT THROUGH THE AREA AND HIGH PRESSURE
MOVING IN FROM ALBERTA. THIS WILL BRING STRONG NORTHWEST FLOW TO
THE REGION. THE RESULT WILL BE DRY AND COOL WEATHER WITH BELOW
NORMAL TEMPERATURES FOR THURSDAY AND FRIDAY.

THEN FOR SATURDAY THROUGH MONDAY A WEST COAST RIDGE BUILDS IN
BRINGING BACK THE ABOVE NORMAL TEMPERATURES AND CONTINUED DRY
WEATHER.

DAY 8 NEXT TUESDAY THE EC AND GFS DO HAVE DIFFERENT IDEAS
THEREFORE WILL OPT FOR DAY 7 PERSISTENCE FOR NOW.       PROTON

&&

.AVIATION...
VFR CONDITIONS LOOK TO PERSIST ACROSS THE TERMINALS KGGW...KOLF
AND KSDY WITH LINGERING SHOWERS AND THUNDERSTORMS PASSING THROUGH
THE KGDV TERMINAL UNTIL 03Z. AFTER THE STORMS DIE DOWN AROUND THE
KGDV TERMINAL EXPECT THE LIGHT EASTERLY WINDS MOSTLY UNDER 10
KNOTS AT ALL TERMINALS TONIGHT.

TOMORROW MORNING THE WINDS WILL VEER TO WEST AT THE KGGW TERMINAL
BY MID MORNING. THE KSDY TERMINAL WILL BE THE LAST TO SEE THE WIND
SHIFT TO THE WEST BY 23Z. WIND SPEEDS WILL RANGE FROM 10 TO 15
KNOTS WITH OCCASIONAL GUSTS OVER 20 KNOTS DURING THE AFTERNOON.
BETWEEN 00Z AND 03Z THE WINDS WILL VEER TO THE NORTH AT THE KGGW
AND KOLF TERMINAL INCREASING TO BETWEEN 20 AND 30 KNOTS. THE SAME
SHIFT WILL TAKE PLACE AT THE KSDY AND KGDV TERMINALS AS A STRONG
COLD FRONT MOVE THROUGH THE REGION.

ALSO ALONG WITH THE FRONTAL PASSAGE EXPECT SHOWERS AND
THUNDERSTORMS AND TEMPORARY MVFR CONDITIONS AT ALL TERMINALS
TUESDAY EVENING. RSMITH
