Weather Synopsis for Wednesday & Monday
The Pacific Northwest remains in a cool and active spring pattern. An E-W oriented frontal system passing the northern tip of Vancouver Island Wednesday morning will drop SE today bringing increasing snow to the mountains (rain below 3000-4000 ft depending on location) today. Moisture is already increasing out ahead of the system. A weak convergence zone lingers across the Skagit Valley and is expected to dissipate as more continuous precipitation arrives. Snow levels are relatively low for April with Mt. Rainier, Stevens Pass, and Mt. Baker expected to pick up accumulating snowfall. Diurnal temperature range along with slight warming associated with the incoming system will bump snow levels slightly upward in the afternoon. Winds will also increase slightly into the moderate range in most Washington locations by afternoon, whereas they will remain strong in the Mt. Hood region.
Overnight, the frontal system is expected to linger over the southern Washington Cascades and Mt. Hood areas. These areas are expected to receive heavy accumulations, particularly at Paradise, White Pass, and Mt. Hood. Crystal Mountain is expected to be partially shadowed by Mt. Rainier throughout the storm.
Another weak disturbance arrives from the WNW on Thursday, helping to sustain the snow (and low elevation rain) throughout the day as a ridge builds offshore and turns the upper-level flow NWerly late in the day.
