Synopsis
Expect cool, breezy, and showery weather this week. The most
widespread precipitation will likely occur Tuesday night into
Wednesday with the potential for a half inch or more of rain over
portions of the idaho panhandle. A ridge of high pressure next
weekend has the potential to bring the region a day or two of
drier weather.

Discussion
Moist southwest flow aloft will keep cloud cover across the
much of the region. The remains of a frontal band lie across
southeast wa and the southern panhandle with light showers.

Instability will increase over northeast washington and north
idaho under the diffluent flow and colder temperatures aloft.

There is a small possibility of lightning near the canadian border
late this afternoon. Convection will continue into the evening
with the arrival of a shortwave rotating across the columbia
basin. Could see some gusty winds with this convection. Anticpate
clouds and winds to taper off overnight. /rfox.

Aviation
18z tafs: the remains of a frontal boundary will keep light
showers and areas of MVFR CIGS to klws-kpuw. Areas of MVFR cigs
span across north idaho. Meanwhile surface based convection will
increase across the northern mountains with scattered showers.

Gusty winds with speeds up to 20kt for the afternoon. Showers will
increase across the TAF sites late this afternoon and evening with
the passage of a shortwave. Anticipate clearing and lighter winds
overnight. Areas of MVFR CIGS are likely by early morning with an
increasing chance of light rain. /rfox.

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.
