Updated aviation discussion

SHORT TERM. TONIGHT THROUGH TUESDAY . An upper level trough off the coast will continue to influence the regional weather by inducing periods of showery weather. At the heart of the trough is a closed low pressure currently off the coast of Canada. This low will slowly drop southward and be along the Oregon coast by Tuesday. In doing so it will send some occasional impulses across the forecast area under a southwest flow aloft. It will also increase shallow Spring time instability helping enhance shower activity during the afternoons. Snow levels will range from 2000 to 3000 feet but occasional dip lower in the overnight periods. However, the showery nature of the precipitation means that snow accumulations will be spotty and will quickly melt.

One of those impulses will arrive early Monday and spread some light showery precipitation mainly across central and eastern Oregon. Some of this could be snow showers producing some light accumulations which is expected to melt quickly once the sun is up. This will be followed by increasing shallow instability midday and afternoon producing more convective showers. These showers will begin to decrease around sunset with most ending by midnight with possible exception of far eastern mountains. Showers will then return on Tuesday midday and afternoon as the heating of the day induces the shallow instability which in turn develops into showers. These showers to will begin to fade out around and after sunset Tuesday.

LONG TERM. WEDNESDAY THROUGH SUNDAY . The upper level low off the Oregon Coast will eventually drop down into California on Wednesday. This will push the upper level trough across the region for one last day of cool showery weather. The trough will exit to the east on Thursday with just a few lingering showers over the eastern mountains. Meanwhile, an upper level ridge will build into and over the region Thursday through Saturday for a stretch of warmer and dry weather. A high degree of model uncertainty begins going into next weekend. The GFS wants to begin breaking down the ridge and have the next upper level trough arriving late Saturday into Sunday with possible precipitation. However, the ECMWF wants to hold the ridge in position over the region through Saturday and then just flatten the ridge on Sunday but stay dry. Opted to keep a dry forecast through Saturday and then introduce just a slight chance of showers on Sunday.

AVIATION. 00Z TAFs . VFR conditions will continue for all location with the possible exception of BDN and RDM where some rain/snow showers will become possible Monday locally reducing VSBYs and CIGS to possible MVFR to IFR briefly. 10-20kts winds will drop to less 10 kts after sunset.
