Strong winds across northern rockies on Wednesday...

Discussion
High pressure will remain over the northern rockies through
tonight. Light winds and mild overnight temperatures will be
present.

A strong, yet dry, cold front will sweep across the northern
rockies on Wednesday, creating strong wind gusts region-wide.

Wind highlights are in effect for Wednesday, covering all of
western montana and lemhi county idaho. The strongest winds,
gusting over 60 mph at times, will exist over high terrain and
across southwest montana. Elsewhere, gusts over 40 mph will
develop during Wednesday daytime. These strong winds will damage
trees and create dangerous crosswinds for highway travelers. The
winds will be strong enough to also create unrelenting waves up to
5 feet high on flathead lake Wednesday afternoon. Some shower and
thunderstorm activity will follow the cold front, but even this
will be sparse compared to most cold fronts. Very little
precipitation is anticipated through Wednesday night, as winds
slowly subside after sunset.

Shower and afternoon thunderstorm activity will linger over the
northern rockies through the end of the week; however,
expectations for widespread precipitation remain fairly low.

Memorial day weekend, high pressure is expected to develop along
the pacific northwest coast and then slowly creep east over time,
steadily warming and drying the northern rockies. Memorial day
may actually be warmer than 80 degrees for low elevations, a
notable rarity over the past several decades.

Aviation No impacts to aviation are expected this afternoon and
evening, with warm, summer-like temperatures and light winds.

Overnight into early Wednesday morning, winds will rapidly
increase 1000 to 2000 ft above the surface, causing significant
speed sheer as one rises in the atmosphere. A dry cold front will
push south Wednesday morning through northwest montana, eventually
reaching southwest montana by the afternoon and evening. Winds
will be strong tomorrow afternoon, with gusts in the 30 and 40
knot range becoming common at most western montana sites.

Airstrips in idaho and clearwater county idaho will be spared the
strongest winds, but it will still be a breezy day across the
northern rockies. Very little precipitation is expected with this
dry front.

Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors. Please verify all results. 5) Weather information is from numerious of sources and is presented automatically. It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
