AREA FORECAST DISCUSSION...UPDATED
NATIONAL WEATHER SERVICE GLASGOW MT
839 PM MDT MON AUG 22 2011

.SHORT TERM...FOR NORTHEAST MONTANA...TONIGHT THROUGH WEDNESDAY...

SENT AN UPDATE TONIGHT MAINLY FOR THE FIRE WEATHER SITUATION AND
TO CANCEL THE RED FLAG WARNING. THE EVENING HOURS HAVE BROUGHT
DIMINISHING WINDS AND COOLER TEMPERATURES ACROSS NORTHEAST
MONTANA. RELATIVE HUMIDITIES ARE NOW CLIMBING ABOVE 20 PERCENT.
WINDY AND DRY CONDITIONS ARE EXPECTED TO RETURN BY MID DAY
TUESDAY...ALTHOUGH NOT QUITE AS DRY AS EXPERIENCED TODAY. BMICKELSON

PREVIOUS SHORT TERM DISCUSSION...THE WEAK SHORTWAVE DISTURBANCE
IN THE UPPER FLOW MOVES EAST OF THE AREA TONIGHT ALLOWING THE
RIDGE TO REBOUND SLIGHTLY. HOWEVER ON TUESDAY A BROADER AND MORE
SUBSTANTIAL UPPER SHORTWAVE MOVES EAST ACROSS THE CANADIAN PRAIRIE
FLATTENING THE RIDGE AND SENDING A DISTINCT DRY COLD FRONT SOUTH
OVER NORTHEAST MONTANA. THE MAIN RESULT OVER NEMONT WILL BE
ENHANCED NORTHWESTERLY WINDS. MODEL GUIDANCE SUGGESTS 25KT WIND
WHILE BUFKIT ADDS MOMENTUM TRANSFER FROM 700MB ADDING GUSTS OF
35KT. THEREFORE AN ADVISORY FOR FORT PECK LAKE HAS BEEN ISSUED FOR
TUESDAY. THE COOLER AIR BEHIND THE COLD FRONT WILL KNOCK DOWN
MAXIMUM TEMPERATURES BY AROUND 5*F FROM THOSE OF TODAY. THEREFORE
RELATIVE HUMIDITIES WILL BE LESS CRITICAL THAN THOSE OF TODAY. BUT
WITH THE STRONGER WINDS...FIRE WEATHER CONCERNS WILL CONTINUE. SEE
FIRE WEATHER DISCUSSION.

AFTER THE CANADIAN SHORTWAVE MOVES EAST BY WEDNESDAY THE UPPER
RIDGE WILL ONCE AGAIN AMPLIFY OVER MONTANA. THEREFORE MAXIMUM
TEMPERATURES WILL REMAIN WARM AND CONDITIONS WILL CONTINUE DRY. A
DEVELOPING LEE TROUGH IN ALBERTA WILL MAKE WIND SOUTHERLY AT
AROUND 10KTS. SCT

.LONG TERM...WEDNESDAY NIGHT THROUGH MONDAY...
HOT UPPER RIDGING CENTERED OVER THE FOUR CORNERS REGION WILL
LARGELY DOMINATE THROUGH THE EXTENDED PERIOD. HOWEVER...SHORTWAVE
DISTURBANCES ON THURSDAY AND AGAIN ON SATURDAY WILL BRING CHANCES
FOR SHOWERS AND THUNDERSTORMS AS WELL AS A RETURN TO MORE
CLIMATOLOGICALLY NORMAL TEMPS.

THE GOING FORECAST IS IN OVERALL EXCELLENT SHAPE...ONLY REAL
TWEAK WAS TO THURSDAY AFTERNOON AS AN APPROACHING SHORTWAVE
DISTURBANCE WILL TRIGGER ISOLATED SHOWERS AND THUNDERSTORMS ACROSS
THE WESTERN ZONES...THUS INCREASED POPS. GILCHRIST

PREVIOUS LONG TERM DISCUSSION...STRONG UPPER RIDGE OVER THE WEST
WILL WEAKEN THROUGH THE WEEK AS A SERIES OF FAST MOVING SHORTWAVES
SLIDE THROUGH WESTERN CANADA. THIS WILL RESULT IN GRADUALLY
COOLING TEMPERATURES AND PERHAPS AND INCREASE IN POTENTIAL FOR
RAIN WITH ANY OF THE SYSTEMS.

SHORTWAVE MOVING INTO CENTRAL CANADA ON WEDNESDAY NIGHT WILL PUSH
A FRONTAL SYSTEM ACROSS MONTANA ON THURSDAY. HOT DRY AIR WILL
LINGER ACROSS EASTERN MONTANA BEHIND THE INITIAL FRONT IN THE DEEP
WESTERLY FLOW. THURSDAY NIGHT A SECONDARY FRONT DROPS SOUTH FROM
CANADA BRINGING COOLER AIR INTO THE STATE. ALONG WITH THE COOLER
AIR-MASS WILL BE A SLIGHT INCREASE IN MOISTURE...AND A CHANCE FOR
THUNDERSTORMS THURSDAY NIGHT.

HIGH PRESSURE SLIDES OUT OF SASKATCHEWAN AND INTO NORTH DAKOTA ON
FRIDAY...CLIPPING NORTHEAST MONTANA FOR COOL AND DRY CONDITIONS.
AS HIGH PRESSURE SHIFTS EASTWARD ON SATURDAY...AND ANOTHER
SHORTWAVE PUSHES INTO THE NORTHERN ROCKIES...WARMER AIR WILL AGAIN
BE PULLED NORTHWARD INTO THE STATE. SOUTHEAST LOW LEVEL FLOW WILL
ALSO BE INCREASING SURFACE MOISTURE AHEAD OF THE WAVE. MODELS
INDICATING UPPER TROF TRACKING FARTHER SOUTH THAN MOST RECENT
SHORTWAVES AND FRONT MORE VERTICALLY STACKED...CHANCES FOR RAIN
FOR SATURDAY AND SATURDAY NIGHT MAY BE HIGHER THAN IN RECENT
WEEKS. THIS SHORTWAVE ALSO DEPICTED DIVING INTO THE NORTHERN
MISSISSIPPI VALLEY INSTEAD OF TRACKING STRAIGHT EAST...WHICH COULD
KEEP COLDER AIR OVER THE NORTHERN PLAINS INTO EARLY NEXT WEEK.

.AVIATION...
VFR TONIGHT AND TOMORROW.  WINDS HAVE DECLINED ACROSS THE REGION
THIS EVENING BUT ARE EXPECTED TO INCREASE AGAIN TOMORROW WITH
WESTERLY WINDS TO 20 KTS AND GUSTS TO 30 KTS. NO OBSTRUCTIONS TO
VISIBILITY OR CEILINGS ARE FORECAST...WITH ONLY SOME SCATTERED
HIGH CLOUDS TONIGHT AND TOMORROW. A COLD FRONTAL PASSAGE LATE
TUESDAY WILL VEER THE WINDS TO NORTHERLY. MARTIN

&&

.FIRE WEATHER...

AN UPPER LEVEL RIDGE WHICH IS EXPANDING OVER THE ROCKY MOUNTAINS
AND ADJACENT HIGH PLAINS REGION WILL PUSH TEMPERATURES INTO THE
90S AND UPPER 80S THROUGH MID WEEK. THE EVENING HOURS TODAY HAVE
BROUGHT DIMINISHING WINDS AND COOLER TEMPERATURES ACROSS NORTHEAST
MONTANA. RELATIVE HUMIDITIES ARE NOW CLIMBING ABOVE 20 PERCENT.
WINDY AND DRY CONDITIONS ARE EXPECTED TO RETURN BY MID DAY
TUESDAY...ALTHOUGH NOT QUITE AS DRY AS EXPERIENCED TODAY. HUMIDITY
RECOVERY IS EXPECTED TO BE ONLY MODERATE TONIGHT THROUGH TUESDAY
MORNING.

TUESDAY...A PASSING UPPER LEVEL SHORTWAVE TROUGH MOVING EAST
ACROSS THE SOUTHERN CANADIAN PRAIRIE WILL SEND A COLD FRONT SOUTH
OVER NORTHEAST MONTANA. THIS WILL GENERATE MUCH STRONGER WINDS FOR
THE AREA. HOWEVER...THE FRONT WILL ALSO BRING SLIGHTLY COOLER AIR
INTO THE AREA SO RELATIVE HUMIDITY VALUES WILL RANGE HIGHER AT
AROUND 20 TO 30 PERCENT. WITH THE CONTINUED DRYING AND STRONGER
WINDS...EXPECT CONTINUED BUT MARGINALLY CRITICAL FIRE WEATHER
CONDITIONS FOR TUESDAY AFTERNOON. ADDITIONAL HEADLINES MAY BE
NEEDED. BMICKELSON
