Discussion
This afternoon has become another warm and pleasant fall day with
near seasonable temperatures at 60s and 70s in the valleys.

A weak backdoor cold front from canada will start to make its way
southward along the continental divide and intrude into northwest
montana late tonight into Wednesday morning. As a result, east-
northeast winds will develop over much of western montana by
Wednesday. Winds could be especially breezy where the strongest
gradient resides over the continental divide, and over southwest
montana lemhi county throughout the day on Wednesday.

At the same time, an influx of moisture from the southwest will
begin increasing cloud cover and showers with isolated
thunderstorms across southwest and west-central montana Wednesday
afternoon and evening. The northern extent of the showers will be
limited, with the best chance for the wetting rainfall and
lightning expected to remain over lemhi county and southwest
montana.

Thursday continues to be a showery day across western montana,
especially in the northwest. Other areas including north-central
idaho will see a lesser chance for precipitation.

Friday has been trending milder and drier and it could turn out
to be a delightful day with some high clouds and breezy
conditions. Lows in the morning will be in the 30s, so there could
continue to be a chance for frost for some areas. High
temperatures will generally warm towards seasonable readings.

Other than a few showers over western montana on Saturday, the remainder
of the area will experience near seasonable temperatures. A
trough will begin to influence the weather by Sunday through
early next week. Expect below normal temperatures with above
normal chance for precipitation. Snow levels could fall down to
5000 feet by Monday night along the continental divide.

Beyond that it appears to be unsettled with below normal
temperatures. With a transition to more of a northwesterly flow
setting up next week, there could be one or two mornings where
temperatures are able to dip into the 20s for the first time this
fall.

Aviation Vfr conditions expected. Occasional afternoon and
evening breezes up to 15-20 kts are possible for all TAF sites
through sunset.

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.
