AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MISSOULA MT
837 AM MDT SUN AUG 17 2008

..NEAR RECORD HIGH TEMPERATURES EXPECTED SUNDAY AND MONDAY...
..BIG CHANGE IN THE WEATHER EXPECTED WEDNESDAY INTO THURSDAY...

.DISCUSSION...MADE A QUICK UPDATE TO ADD A SLIGHT CHANCE OF
CONVECTION ACROSS FAR NORTHWEST MONTANA LATE THIS AFTERNOON AND
EVENING. THIS IS FROM SUBTROPICAL MOISTURE SET TO ROUND THE TOP OF
THE RIDGE LATER TODAY. THIS MOISTURE IS CURRENTLY PRODUCING
THUNDERSTORMS OVER WESTERN WASHINGTON...AND WILL MAINLY MOVE INTO
SOUTHERN B.C. AND ALBERTA. BUT IT DOES LOOK LIKE IT WILL BRUSH
NORTHERN LINCOLN COUNTY. ALL ELSE IN THE PREVIOUS FORECAST AND
DISCUSSION LOOKS FINE.

&&

AVIATION...HIGH PRESSURE OVER THE NORTHERN ROCKIES WILL KEEP
CLEAR SKIES AND LIGHT WINDS OVER WESTERN MONTANA AND NORTHERN
IDAHO THROUGH SUNDAY EVENING. THE ONLY EXCEPTION WILL BE ISOLATED
CONVECTION OVER EXTREME NORTHWEST MONTANA LATE THIS AFTERNOON AND
INTO THE EVENING.

&&

.PREV DISCUSSION... /ISSUED 340 AM MDT SUN AUG 17 2008/

DISCUSSION...HIGH PRESSURE CONTINUES TO DOMINATE OVER THE
NORTHERN ROCKIES BRINGING NEAR RECORD HIGHS TO THE FORECAST
THROUGH MONDAY. SUNNY SKIES WILL CONTINUE THE WARMING TREND WE
HAVE BEEN SEEING THROUGH MONDAY. MONDAY DOES BRING A LITTLE CHANGE
AS THE UPPER LEVEL RIDGE SLIDES INTO EASTERN MONTANA AND THE
THERMAL TROUGH THAT HAS BEEN LINGERING TO OUR WEST MOVES INTO
CENTRAL IDAHO. THIS BRINGS SOME STRONGER WINDS IN THE MID LEVELS
AS WELL AS A STRONGER SURFACE PRESSURE GRADIENT. THESE TWO
FEATURES COMBINED WILL BRING SOME BREEZY WINDS OVER CENTRAL IDAHO
AND WESTERN MONTANA. AT THE SAME TIME...DRIER AIR MOVING INTO THE
AREA WILL KEEP HUMIDITIES FAIRLY LOW. MOISTURE STARTS TO INCREASE
LATE MONDAY AND MONDAY OVER CENTRAL IDAHO BRINING THE POTENTIAL
FOR THE DEVELOPMENT OF SHOWERS AND THUNDERSTORMS.

TUESDAY THROUGH SATURDAY...LONG RANGE MODELS SHOWING BETTER
CONSISTENCY IN OVERALL FEATURES THROUGH THE END OF THE WORK WEEK
WITH A BIG CHANGE IN THE WEATHER EXPECTED WEDNESDAY INTO THURSDAY.
TUESDAY WILL BE A TRANSITION DAY AS AN UPPER LEVEL TROUGH OF LOW
PRESSURE APPROACHES THE PACIFIC NORTHWEST. SOUTHWEST FLOW ALOFT
WILL INCREASE AND BEGIN TO USHER IN MOISTURE AND A CHANCE OF
AFTERNOON AND EVENING SHOWERS AND THUNDERSTORMS WITH HIGHS COOLING
SLIGHTLY. ON WEDNESDAY...THE APPROACHING TROUGH BEGINS TO DEEPEN
OVER VANCOUVER ISLAND AND PUSH A COLD FRONT INTO THE NORTHERN
ROCKIES. ALTHOUGH THERE ARE SOME TIMING DIFFERENCES IN THE MODELS
OF WHEN THE FRONT WILL MOVE INTO ID AND MT...ALL ADVERTISE
WIDESPREAD SHOWER ACTIVITY TO SPREAD INTO THE REGION BY WEDNESDAY
AFTERNOON AS A STRONG JET STREAM PUNCHES INTO THE PACIFIC
NORTHWEST. THE MODELS HINT AT SOME HEAVY DOWNPOURS POSSIBLE OVER
HIGHER TERRAIN. MUCH COOLER DAYTIME TEMPERATURES WILL BE
EXPERIENCED WEDNESDAY INTO THURSDAY AS THE TROUGH MOVES INLAND
OVER ID AND MT THURSDAY AFTERNOON. AS THE AIRMASS COOLS AND
BECOMES MORE UNSTABLE THURSDAY...WIDESPREAD SHOWERS AND ISOLATED
THUNDERSTORMS ARE EXPECTED INTO THE EVENING HOURS. ON FRIDAY...THE
UPPER LEVEL TROUGH BEGINS TO MOVE EAST OF THE DIVIDE AS HIGH
PRESSURE BEGINS TO BUILD BACK INTO THE PACIFIC NORTHWEST. SOME
LINGERING SHOWERS MAY EXIST EARLY FRIDAY BEFORE A DRYING AND
WARMING TREND BEGINS BY AFTERNOON. HIGH PRESSURE WILL BUILD OVER
ID AND MT NEXT WEEKEND WITH SEASONABLE TEMPERATURES EXPECTED.

FIRE WEATHER...THE PALOUSE AND HELLS CANYON AREA WILL SEE THE
BEST COMBINATION OF AFTERNOON/EVENING WINDS AND LOW HUMIDITIES ON
MONDAY AND THEREFORE THAT IS THE AREA FOR THE WATCH. LOW
HUMIDITIES AND INCREASING WINDS OVER THE BEAVERHEAD-DEERLODGE AREA
WILL ALSO HAVE TO BE WATCHED ON MONDAY AS THIS AREA MAY NEED A
HIGHLIGHT AS WELL. HAINES INDEX WILL BE AT THE HIGH LEVEL
THROUGHOUT THE AREA ON MONDAY.
