.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

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.
