Area forecast discussion, Jul 10, 10:00 AM MDT, 1 hour 36 minutes before
AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MISSOULA MT
1000 AM MDT THU JUL 10 2008
.UPDATE...HAVE UPDATED THE WIND FORECAST FOR TODAY. HAVE ALSO
ISSUED A HIGH WIND WARNING ABOVE 6000 FEET FOR GLACIER NATIONAL
PARK.
&&
.DISCUSSION...THE 12Z RUN OF THE NAM FELL BACK INTO LINE WITH
MODEL DATA FROM YESTERDAY. ANALYSIS OF THE MODEL WHEN COMPARED TO
RAOBS FROM THIS MORNING REVEAL THAT THE NAM HAS INITIALIZED WELL
AND THUS WAS LEANED UPON HEAVILY FOR WIND GUIDANCE TODAY. A
DISTINCT DRYING IS APPARENT ON WATER VAPOR IMAGERY OVER SOUTHERN
BRITISH COLUMBIA...INDICATIVE OF AN ACCELERATION IN THE JET
STREAM. THIS JET IS FORECAST TO MOVE OVER NORTHWEST AND WEST
CENTRAL MONTANA DURING THE AFTERNOON AND EVENING HOURS. ANALYSIS
OF MODEL POTENTIAL VORTICITY DATA SHOWS THESE UPPER LEVEL WINDS
DROPPING TO THE LOWER ELEVATIONS LATER DURING THE AFTERNOON AND
PERSISTING IN THE THE EARLY EVENING. THIS WILL HELP INCREASE WINDS
PRODUCED AT THE SURFACE DUE TO A VERY TIGHT PRESSURE GRADIENT
ALONG THE DRY COLD FRONT.
GIVEN THESE FACTORS AND THE FACT THAT WE ARE IN THE HEIGHT OF
TOURIST SEASON OVER LOGAN PASS...WE FEEL THAT IT IS MORE PRUDENT
TO HAVE THE HIGH WIND WARNING IN EFFECT FOR THE ANTICIPATED STRONG
WINDS THIS AFTERNOON ABOVE 6000 FEET. LOCATION BELOW 6000 FEET
WILL EXPERIENCE ADVISORY LEVEL WINDS SUSTAINED AT 20 TO 30 MPH
WITH GUSTS TO 45 MPH.
FINALLY WE HAVE CHOSEN TO KEEP THE LAKE WIND ADVISORY IN EFFECT
THIS AFTERNOON THROUGH THE EVENING ACROSS FLATHEAD LAKE. ALTHOUGH
THE PRESSURE GRADIENT IS NOT OPTIMUM FOR STRONG WINDS ACROSS THE
LAKE. WE BELIEVE THE COMBINED FACTORS MENTIONED ABOVE WILL PRODUCE
DANGEROUSLY HIGH WINDS AFFECTING MARINE INTERESTS ACROSS THE LAKE
THIS AFTERNOON THROUGH THIS EVENING. THE ONLY CHANGE WAS TO
ADJUST THE START TIME OF THIS ADVISORY.
&&
AVIATION...VERY STRONG WINDS...BOTH AT THE SURFACE AND
ALOFT...CAN BE EXPECTED THIS AFTERNOON. GUSTS TO 30 KNOTS CAN BE EXPECTED
AT KGPI...KMSO AND KBTM DURING THE AFTERNOON.
&&
.PREV DISCUSSION... /ISSUED 339 AM MDT THU JUL 10 2008/
DISCUSSION...A PACIFIC TROUGH WILL MOVE ACROSS SOUTHERN CANADA
TODAY. THE LOW AND THE PRECIPITATION WILL REMAIN NORTH OF THE
BORDER...WITH A SLIGHT CHANCE OF A THUNDERSTORM IN FAR NORTHWEST
MONTANA LATER THIS AFTERNOON. A DRY COLD FRONT WILL PUSH ACROSS
WESTERN MONTANA THIS AFTERNOON AND EVENING...THIS WILL PRODUCE A
VERY TIGHT SURFACE PRESSURE GRADIENT...THIS ALONG WITH A STRONG
UPPER LEVEL JET MOVING ACROSS THE REGION WILL PRODUCE WINDY
CONDITIONS ACROSS WESTERN MONTANA. THE STRONGEST WINDS WILL BE
ABOVE 6000 FEET OVER GLACIER NATIONAL PARK AND THE BUTTE BLACKFOOT
REGION...WIND GUSTS OVER 60 MPH ARE POSSIBLE THROUGH MCDONALD PASS
AND AT LOGAN PASS. THE LOWER ELEVATIONS OF GLACIER PARK WILL SEE
WINDS OF 30 TO 40 MPH WITH LOCALIZED HIGHER GUSTS...SINCE THESE
WINDS WILL BE MORE WIDESPREAD THEN THE AREAS THAT REACH HIGH WIND
CRITERIA...I HAVE DECIDED TO CANCEL THE HIGH WIND WARNING FOR
GLACIER NATIONAL PARK ABOVE 6000 FEET AND REPLACE IT WITH A WIND
ADVISORY FOR ALL ELEVATIONS. ALSO EXPECT AFTERNOON WINDS OVER FLATHEAD LAKE
TO REACH 20 TO 25 MPH AND HAVE ISSUED A LAKE WIND ADVISORY FROM
NOON UNTIL 9 PM. THE PRESSURE GRADIENT WILL WEAKEN DURING THE
EVENING AND THE WINDS WILL DECREASE...BUT EXPECT BREEZY CONDITIONS
TO CONTINUE THROUGH MOST OF THE NIGHT.
ON FRIDAY THE TROUGH WILL BE MOVING OFF TO THE EAST WITH A RIDGE
REBUILDING INTO THE REGION.
SATURDAY THROUGH WEDNESDAY...SOME MONSOONAL MOISTURE WILL WORK ITS
WAY INTO THE RIDGE ON SUNDAY AND MONDAY BRINGING THE POTENTIAL OF
SOME ELEVATED THUNDERSTORMS TO THE REGION. THE POTENTIAL FOR
THUNDERSTORMS INCREASES ON TUESDAY AS MORE MOISTURE WORKS ITS WAY
INTO THE NORTHERN ROCKIES AHEAD OF AN APPROACHING SHORTWAVE
TROUGH. HIGH TEMPERATURES THROUGH THE EXTENDED SHOULD STAY ABOVE
AVERAGE FOR THIS TIME OF YEAR.
FIRE WEATHER...EXTREME FIRE WEATHER CONDITIONS WILL BE POSSIBLE
ACROSS PORTIONS OF WRN AND SW MT THIS AFTERNOON. A WEATHER SYSTEM
WILL MOVE EAST ACROSS THE DISTRICT DURING THE DAY. GUSTY WINDS OF
40 TO 50 MPH ALONG WITH VERY LOW RH LEVELS ARE POSSIBLE. AREAS
MOST IMPACTED WILL BE THE LOWER AND MIDDLE ELEVATIONS WHERE THE
FUELS (MAINLY GRASSES) HAVE BEGUN TO CURE.
ON SUNDAY AND MONDAY AFTERNOONS...THERE WILL BE A SLIGHT CHANCE
FOR THE DEVELOPMENT OF HIGH BASED-LOW PRECIPITATION PRODUCING
THUNDERSTORMS OVER PORTIONS OF NORTH CENTRAL IDAHO AND SW MT.
