Synopsis
Showers and gusty winds can be expected today and tonight as a low
pressure system swings through the area. There will be a low end
chance for lightning up across the northeast mountains
this afternoon. After a brief break in the active weather tonight,
the next storm system will arrive Saturday morning and will exit
Sunday night. This storm will also be warm, wet, and windy. Drier
conditions are expected for much of next week as high pressure
moves into the region.

Discussion
Morning update: the band of steady rain tied to the cold front is
finally shifting to the east and is close to clearing east of
idaho. A cold upper-level trof will settle in behind the cold
front bringing a renewed threat for isolated showers with
afternoon heating. The mountains of NE wa and N id will carry the
greatest threat with gusty winds the main story for the columbia
basin, palouse, and blue mountains. This morning allowing for
sunbreaks across much of central wa.

We will be focusing on several items for the afternoon forecast
package. 1) a puget sound convergence zone will bring a narrow
but enhanced band of heavier snow to a small area of the cascade
crest. This may impact stevens pass. 2) widespread precipitation
for Saturday with the onset being snow for much of the cascades
above 3000 feet bringing potential for travel impacts on the
passes. This includes stevens, blewett, loup loup, washington, and
possibly sherman. 3)potential for strong winds early Sunday
morning into Sunday afternoon for southeastern wa including the
palouse, blue mountains, and into the lower idaho panhandle. Sb

Aviation
18z tafs: band of steady rain will shift east into montana.

Residual moisture and favored boundary layer flow will keep MVFR
cigs arnd the eastern terminals 18-20z then lift above 3k agl.

Atmosphere becoming increasingly unstable this aftn under a -28c
cold pool promoting convective showers across NE wa, N id, and
cascade crest. A few lightning strikes will be possible 20-23z.

Gusty westerly winds to impact most terminals through the day.

Winds decrease some after 00z but will remain steady until backing
to the south southeast ahead a moist laden warm front. May have a
few hours of MVFR CIGS prior to the wind switch. Next frontal
system to bring top-down moistening Sat morning with the onset of
pcpn 15-19z in a general west to east fashion. Sb

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.
