Weather Synopsis for Sunday & Monday
With a cold upper trough remaining in place and an upper low parked just offshore, Sunday will be quite similar to Saturday. Light to occasionally moderate snow showers focus on the west slopes of the Cascades and southern Olympics, with increasing spillover to the lee side of the ranges during the afternoon as convection builds up. Convective showers come with graupel and, in isolated cases, some small hail. Snow showers will be heaviest in the southern Washington Cascades, with Mt Rainier and Mt St Helens both likely to pick up 6-12" of snow by the end of the day. Mt Baker, the central Cascades Passes, and Mt Hood can expect 2-6" of snow. Winds have decreased significantly and are mostly light across Washington State. However, as a disturbance rotates through southern Washington State, a more westerly component has increased moderate wind speeds and strong gusts early this morning for the east slopes of Mt Hood.
Snow showers decrease during the evening hours, but another weak disturbance passing through the southern Cascades in the early morning hours on Monday could bring a period of moderate snowfall from around Snoqualmie Pass to Mt Hood. Scattered light to occasionally moderate snow showers continue on Monday.
Snow levels remain vacillating between sea level and 1500 ft with diurnal fluctuations. Afternoon freezing levels rise to 1500-3000 ft in areas not receiving snowfall.
