1104 pm pdt Wed mar 22 2017

Synopsis Showers and a few isolated thunderstorms will be
possible today. A few isolated mountain showers will be possible
for Thursday, otherwise it will be dry. Then another storm system
will bring widespread rain and mountain snow Friday. Flooding
issues will persist through much of the week in the absence of a
prolonged period of dry weather. The weather will remain unruly
through the first part of next week as a couple more storm systems
are expected to track through the region.

Discussion
The vorticity maximum is tracking through the area as anticipated
with the previous updated from earlier. Most organized shower
activity with the vorticity maximum has tracked across the upper
basin to just north of spokane at 11 pm. These showers will
continue on their easterly track toward sandpoint by around
midnight and then exit the region around 2 am. /svh

Aviation
06z tafs: scattered showers will track generally north of a line
from kgeg to kcoe late this evening. Low stratus will remain over
the spokane-coeur d'alene corridor through the rest of tonight
into Thursday morning. I have moderate confidence that fog will
develop at klws late tonight and lingering into early Thursday
morning and low confidence for some fog developing in kmwh. The
atmosphere will be more stable on Thursday with dry conditions and
terminals becomingVFR by the afternoon. /svh

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.
