AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GREAT FALLS MT
237 PM MDT WED JUL 9 2008

.DISCUSSION...

TONIGHT THROUGH FRIDAY...MAIN CONCERN THIS AFTERNOON WILL BE A
STRONG SHORTWAVE TROUGH AND ASSOCIATED SURFACE LOW PRESSURE
SYSTEM/COLD FRONT THAT WILL MOVE THROUGH THE REGION ON THURSDAY. A
COMBINATION OF STRONG UPPER LEVEL WINDS AND TIGHT SURFACE PRESSURE
GRADIENTS WILL CAUSE WINDS TO INCREASE ACROSS MUCH OF MY FORECAST
AREA. IN PARTICULAR...HIGHER ELEVATIONS OF GLACIER NATIONAL PARK
AND GOING TO THE SUN ROAD COULD RECEIVE WIND GUSTS OF 60 TO 70 MPH
AT TIMES. AS A RESULT...I HAVE ISSUED A HIGH WIND WARNING FOR THE
NORTHERN ROCKY MOUNTAIN FRONT FOR THURSDAY AND THURSDAY EVENING.
ISOLATED TO SCATTERED THUNDERSTORMS WILL ALSO AFFECT MY FAR
NORTHERN ZONES AS THE SYSTEM MOVES THROUGH. BEHIND THE
SYSTEM...TEMPERATURES WILL COOL TO NEAR OR BELOW SEASONAL AVERAGES
ON FRIDAY. WINDS WILL ALSO DIMINISH FROM THOSE OF THURSDAY
ALTHOUGH BREEZY NORTHWEST WINDS ARE ANTICIPATED TO CONTINUE
THROUGH THE DAY. MPJ

FRIDAY NIGHT THROUGH MONDAY NIGHT...A DRY AND COOL NORTHWEST FLOW
ALOFT OVER NORTH CENTRAL...CENTRAL...AND SOUTHWEST MONTANA WILL KEEP
SKIES PARTLY CLOUDY FRIDAY NIGHT WITH LOW TEMPERATURES BELOW
SEASONAL AVERAGES. AN UPPER LEVEL RIDGE OF HIGH PRESSURE WILL THEN
REBUILD OVER THE AREA ON SATURDAY...AS TEMPERATURES WARM TO NEAR
NORMAL. A FEW WEAK DISTURBANCES MOVING THROUGH THE RIDGE WILL BRING
A SLIGHT CHANCE OF THUNDERSTORMS TO THE MOUNTAINS. A SHORTWAVE
TROUGH WILL GRADUALLY APPROACH MONTANA FROM THE WEST SUNDAY THROUGH
MONDAY NIGHT. THE RESULTING INCREASINGLY MOIST AND UNSTABLE
SOUTHWEST FLOW ALOFT WILL BRING AT LEAST A SLIGHT CHANCE OF
THUNDERSTORMS TO MOST OF THE AREA MAINLY DURING THE AFTERNOON AND
EVENING HOURS. SURFACE WINDS WILL INCREASE AND BECOME WESTERLY...AS
TEMPERATURES WARM TO ABOVE NORMAL LEVELS AHEAD OF A COLD FRONT
ASSOCIATED WITH THE APPROACHING SYSTEM.  COULSTON

TUESDAY THROUGH WEDNESDAY...MODELS ARE IN PRETTY GOOD AGREEMENT
DURING THIS PERIOD. A WEAK SHORTWAVE TROUGH...OFF THE WEST COAST
TUESDAY...DRIFTS EAST DURING THIS PERIOD. LIMITED MOISTURE AND
ENERGY WITH A FEW DISTURBANCES IN A SOUTHWESTERLY FLOW ALOFT WILL
RESULT IN PARTLY TO MOSTLY CLOUDY SKIES...WITH ISOLATED...MAINLY
AFTERNOON AND EVENING SHOWERS AND THUNDERSTORMS. TEMPERATURES SHOULD
BE NEAR SEASONAL AVERAGES.  EK

.AVIATION...
UPDATED 1747Z.
HIGH PRESSURE WILL BE THE DOMINANT WEATHER FEATURE IN THE REGION
DURING THE NEXT 24 HOURS. VFR FLIGHT CONDITIONS ARE ANTICIPATED TO
PREVAIL DURING THIS TIME...WITH EITHER HIGH VFR CEILINGS OR SKY
CLEAR PRESENT. SURFACE WINDS ARE ANTICIPATED TO GUST UP TO 25KT NEAR
KCTB...KGTF...AND KHLN THRU 04Z. SURFACE WINDS WILL DECREASE
THEREAFTER AT ALL AREA TERMINALS...HOWEVER INTENSIFYING AFTER 15Z AS
A WEAK DRY PACIFIC STORM SYSTEM APPROACHES THE REGION FROM OVER THE
CANADIAN ROCKIES. ZUMPFE

.FIRE WEATHER...
WINDY AND VERY WARM CONDITIONS WILL PREVAIL ON THURSDAY AS A LOW
PRESSURE SYSTEM MOVES THROUGH THE AREA. FIRE AGENCIES ARE REPORTING
THAT FUELS ARE STILL FAIRLY GREEN ACROSS MOST OF MY FORECAST AREA.
