1036 pm pdt Sun mar 24 2019

Synopsis
A storm system will move north through the region tonight for a
chance of rain and mountain snow. A second storm system will
follow quickly Monday night. Both of these storms will result in
low elevation rain and mountain snow. The remainder of the work
week will see spring like conditions with afternoon showers at
times.

Discussion
Evening update: a weak short wave responsible for producing a
band of light rain and mountain snow has lifted into the northern
valleys and mountains as of 9 pm. Models show this to slowly lift
north through the night with dry conditions favored for the rest
of tonight across the columbia basin, spokane coeur d'alene area,
and points south. The forecast was updated based on radar trends.

Also, the boundary layer will remain very moist tonight over the
northern valleys with stratus limiting temperature falls so did
adjust lows upward in this area as well as along the east slopes
of the cascades for the same reason. Patchy fog is also expected
in these areas which may expand overnight into the moses lake and
spokane coeur d'alene area as breaks in the cloud cover develops
promoting radiational fog. This is not expected to be a
significant impact on a regional scale as boundary layer winds out
of the east-southeast at 5-10 kts isn't favorable for widespread
development. However localized visibility restrictions are
possible. Jw

Aviation
06z tafs: the boundary layer has moistened considerably compared
to 24 hours ago with areas of MVFR stratus most prevalent near and
north of i-90 as of 05z this evening. Overnight into Monday
morning boundary layer winds shift to the east- southeast ahead of
an approaching system pooling the greatest bl moisture into the
cascades including keat as well as the northern valleys. Meanwhile
some drying in the bl should bring rising CIGS to
kgeg ksff kcoe kpuw klws with mainlyVFR conditions expected
through 06z Tuesday. Jw

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.
