Weather Synopsis for Monday night through Wednesday
An open trough centered along the west coast of the US spawned a subtle surface low pressure over southwestern Washington as of Monday afternoon. This surface low brings banded showers into the Mt Hood and southern Washington Cascades on SW flow with a more organized precipitation band extending from the Washington Coast over the Olympics to Snoqualmie Pass.
The low center drifts gradually northward Monday night into early Tuesday, shifting across the Cascades during the afternoon. As E flow decreases to the point of irrelevance, expect periods of light rain and snow with precipitation enhanced slightly for the southern Cascades volcanoes. Winds will be very light on Tuesday, so bands of precipitation or showers could linger for multiple hours in some places and may miss others.
Light rain and snow showers continue Tuesday night as the trough axis shifts eastward. Clouds increase once again overnight with light rain and snow redeveloping by morning as a weak frontal system approaches the coast from the NW.
The weak front shifts by the area on Wednesday with light snow showers. More of the energy and moisture shifts to our south.
