What's New / NOTES
6/25/2017 - NOAA is having a major issue that impact the 7 day forecast load times. Many users are reporting problems. The issue has been reported.
5/23/2017 - Worked with NOAA again to speed up the 7 day forecast load times. Thanks to them for being responsive.
5/19/2016 - There were issues with the 3 day airport observation history. I switched to another data source. Let me know if you see any issues with the data feeds.

Discussion An easterly pressure gradient over north-central
idaho and western montana has resulted in a mix of cloud cover
and easterly winds. This has allowed many locations to clear out
and warm into the 40s. The gradient and winds should be enough to
keep most of the fog threat to a minimum tonight but some areas
could see redevelopment of low clouds across portions of western
montana.

Light precipitation remains in the forecast for Tuesday afternoon
and evening, but the weakening nature of the shortwave as it
moves through the area makes for better precipitation chances in
idaho and along the id mt border and only low chances for
measurable precipitation in western montana.

Thursday marks the beginning of an active, more wet, and cooler
weather pattern. Ahead of Thursday's trough, temperatures are
expected to be quite mild before the cold front passes. This cold
front is forecast to arrive in parallel with the upper jet which
usually makes for a slow passage and a better precipitation
producer. Snow levels and the freezing rain threat are the main
challenges with this upcoming weather system. Snow levels are
likely to start off fairly high, but cooler air and increased
precipitation intensity have the potential to bring lower snow
levels as the weather system evolves. For now the locations with
the freezing rain potential Thursday morning appear to be in
northwest montana, where temperatures are most likely to be near
to below freezing when the precipitation begins. Warm
temperatures followed by snow and cooling temperatures will bring
the chance for snow- packed and slick road conditions by Thursday
evening with the highest potential to be in southwest
montana. North-central idaho and west-central montana may also
see degraded travel conditions by late Thursday but confidence is
not as high. Ahead of the cold front passage, expect gusty winds
over 40 mph across southwest montana and near grangeville early on
the day Thursday.

After Thursday, the pacific northwest will remain under the
influence of a large scale trough pattern with numerous snow
producing weather systems expected. The timing and strength of
individual shortwave troughs are still to be determined but there
is increased confidence for a prolonged active and cooler weather
pattern to develop.

Aviation Surface weather observations show increased easterly
winds in much of north-central idaho and western montana. The
pressure gradient causing these winds will remain through much of
tonight which will help keep fog from developing in most places.

Stratus clouds that are currently over portions of western
montana and portions of north-central idaho has decreased in
coverage this afternoon but model cross sections show enough low
level moisture for the stratus to expand overnight. Many of the
valleys of north-central idaho and western montana will see
impacts from lowered ceilings through Tuesday morning. Mid-level
cloud cover will increase on Tuesday with an approaching shortwave
trough and precipitation chances will increase through the day.

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.
