Discussion
Showers move out today as a ridge builds over the northern
rockies. This will bring clearing skies and pleasant, seasonable
temperatures tonight and Sunday. The ridge is short-lived, though,
as another fast-moving upper level trough arrives early Monday
morning. With the exiting of the trough on Monday night, pressure
gradients tighten and a strong jet streak aloft noses its way
into northwest montana. Meanwhile, pacific moisture is transported
over a large, persistent closed high pressure system off of the
northern california coast resulting in some precipitation on
Tuesday. More notably, however, will be strong, gusty winds on
Tuesday afternoon and evening. Wind gusts could reach 30 mph in
the valleys and upwards of 45 mph in the higher terrain. Boaters
on flathead lake should be prepared for windy, choppy conditions.

In the longer term, an upper level low descends down through
british columbia on Thursday, with the associated cold front
crossing the canadian border into montana on Friday morning.

Temperatures drop and precipitation resumes for the weekend with
the frontal passage. Models are agreeing pretty well on this
front. The question at this time is… what type of precipitation
will we see? Snow levels of 5000 to 6000 ft on Friday drop to 3000
to 4000 ft by Saturday morning as low temperatures could easily
hit freezing in the valleys. Expect a cold, wet start to october.

Aviation
Skies clear this afternoon and tonight as a nice, clear day shapes
up for Sunday. Not expecting any aviation impacts in next 24 hours
save some gusty winds at kbtm after 22 00z. Precipitation resumes
on Monday, and Tuesday will see high winds in the afternoon and
evening.

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.
