Weather Synopsis
The cold, unsettled weather will continue through Monday with winter-like temperatures and snow showers across our mountains as a cold upper level trough settles over the PNW. A Puget Sound Convergence Zone that's currently taking shape early this afternoon between the Hwy 2 and I-90 West corridors will likely stack up the most snowfall through the evening with light to moderate showers continuing elsewhere for Mt Hood, the Olympics and near and west of the Cascade crest.
A weak low pressure system moving inland tonight will spread light snow over the area, with a focus on the southwest Cascades and Mt Hood where more moderate amounts are forecast. Mt Hood, St Helens and Mt Rainier may pick up an additional 8-12 inches through Sunday morning. Strong westerly ridgeline winds will begin to peel back for areas north of Hwy 2 tonight as the new low approaches overnight. For areas further south, moderate to strong west winds will continue and actually increase for Mt. Hood where they are already in the strong to extreme range. Over Washington State, snow levels will hover near or just above sea level tonight.
Showers should lighten Sunday morning, but with very cold air aloft, convective showers will fire right back up during Sunday afternoon. In this pattern, the odd lightning strike can't be ruled out, and you should expect to find graupel at times during heavier showers.
A more significant low pressure system will take aim at the region Sunday night and Monday. Forecast models are in somewhat better agreement that the developing low will track further south of Gray's Harbor, pushing inland somewhere along the Oregon coast early Monday morning. This could be another significant April snowstorm for the Mt Hood area, and perhaps the south Washington Cascades. Strong easterly winds should also wreak havoc for much of the area north of the low pressure's track. Upslope flow, may enhance snowfall along the east slopes of the Cascades from the Wentachees (Mission Ridge area) and south. There's a lot to keep tabs on with this dynamic pattern, so check back for updates.

Extended Weather Synopsis
As the aforementioned low-pressure system passes inland Monday night, another upper low will dumbell off the coast Tue/Wed, keeping that cold trough firmly entrenched over the PNW. The details are near impossible to sort out, but we can expect below normal temperatures to continue and the persistent threat of snow showers in the mountains. In this pattern, the Olympics and Mt. Hood area may be the snowfall winners during the middle of the week.
