Weather Synopsis for Saturday & Wednesday
The old frontal boundary that was over the Cascades on Friday has shifted into eastern Washington with a new round of precipitation moving from SW to NE along the boundary and brought some light snow showers to the east slopes of the Cascades overnight. To the west, a cold upper level low and associated upper trough is inching closer to the coast-line. This is allowing the air mass to cool; closer to the upper low and at high elevation weather stations in general, temperatures are in the upper teens to around 20F.
Convective showers will rotate from the low onshore today. A shortwave trough, a marginally unstable airmass, and some March sun will all add up to an increase of afternoon showers this afternoon for the Olympics and west slopes of the Cascades and Passes. Slightly less shower activity is expected for the Mt. Hood area and especially along the east slopes of the Cascades. Snow showers may be moderate at times and mix with graupel. Enhanced shower activity will go through Saturday evening before tapering off after midnight.
The remnants of the upper low in the form of an upper trough will pass through SW British Columbia/NW Washington on Sunday. This will create enough instability for the chance of afternoon showers in the mountains, particularly for the north Cascades (both sides of the crest) and over the Olympics. Mid-level clouds may pass through for areas south, keeping more clouds than sun in the forecast. Overall, temperatures will be a notch cooler on Sunday.
