updated aviation discussion

Short term Tonight through Thursday. Larger upper level low off
the bc coast with several well defined short waves rotating
through. A deep plume of moisture currently over the pacific
northwest. Steady precipitation has been occurring over the
cascades today and has spread east across the forecast area this
afternoon. Expect rain and higher elevation snow to continue
overnight into Wednesday... Mainly focused along the approaching
frontal boundary. Pattern supports heavy precipitation over the
cascades the next 24 hours. Southwest flow with warm advection
will gradually increase the snow levels overnight into Wednesday
morning. However the washington cascades and east slopes will be
slower to warm and will likely see the highest snow accumulations.

The upper low will push a cold front through the region late wed
and snow levels will decrease for all locations. Rain and snow
will taper off Wed night with gradual clearing and much colder
temperatures. The weakening low will move through the area Thursday
with additional rain and mountain snow. 94

Long term Thursday night through Monday. The wet and occasionally
windy conditions will continue through the long term period. A
series of frontal systems will bring areawide rain and snow each
day. Snow levels Thursday night through Friday night will be around
1000-2000 feet msl, so that most of the forecast area will have
snow. Snow levels will then increase with a moist warm front over
the weekend. Models are in good agreement that the warm front will
bring widespread precipitation Saturday, then precipitation tapers
off from the south Saturday night as the front travels north into
b.C. A secondary warm front will follow Saturday night, primarily
affecting washington and far northern oregon. By Sunday, snow
levels are forecast to range from 5000-6000 feet. The
gfs ECMWF canadian also agree on a strong but fast-moving cold front
late Monday and Monday night that could bring snow levels back down
to the columbia basin floor as well as bring gusty winds to the
area. Wister

Aviation 00z tafs... While kykm will continue observe ifr CIGS and
MVFR vsby tonight and periods of light rain, the other TAF sites
will beVFR. However, stratus clouds will keep CIGS around 3500 feet
at kpdt, kalw, kpsc and kdls. Aviation conditions change little
over the next 24 hours, and Wednesday could be similar to today with
areas of light rain and locally MVFR. It is locally windy and krdm,
kbdn, kalw, and kpdt have the potential for southerly winds gusting
to 25-30 knots tonight. Winds will be 10 knots or less elsewhere.

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.
