DISCUSSION. A few lingering snow showers will be present over the higher terrain of southwest Montana this morning, then gradually clearing from northwest to southeast. The Northern Rockies will be between cold troughs over the weekend, with clearing skies and colder than normal overnight temperatures possible. On Saturday night, temperatures single digit below zero will be possible along the Continental Divide and across southwest Montana, with lower teens elsewhere.

Early to middle of next week, the models show a continued active pattern for the Pacific Northwest, but the Northern Rockies look to remain in only light snow events and with seasonal temperatures. The best chances of snow during this time will be over central Idaho and along the ID/ MT border.

By Thursday, a stronger Pacific trough deepens into Northern California, putting the Northern Rockies into a moister southwest flow. Despite the lack of model detail at this time, these scenarios typically mean mountain snows and, depending on initial valley cold pools, possibly some valley snow.

AVIATION. Any remaining snow showers in the vicinity of KBTM and KSMN will dissipate by mid-morning, however may linger higher terrain causing terrain obscurations. Some patchy fog may form in the vicinity of KMSO this morning, especially south of the terminal but should lift by 22/1700z. Expect clearing by late morning from northwest to southeast.

Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors.

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.
