Weather Synopsis for Tuesday & Monday
A progressive weather pattern remains in place. The Pacific Northwest sits between two shortwaves on Tuesday morning. Some very light rain and snow linger from the departed front. Strong winds (particularly through the mountain gaps and areas east of the Cascade Crest) Monday night are coming back down into the moderate range where they should generally remain throughout the day. Westerly flow keeps low-level clouds, moisture and some very light rain or snow possible before it increases during the afternoon ahead of the next approaching front, which should spread increasing light precipitation from Snoqualmie Pass northward during the afternoon hours. Snow levels are slightly above normal, in the 3000-5000 ft range.
The modest front passes during the late evening hours with moderate to strong westerly winds through the mountain gaps with flow accelerating down the east slopes of the Cascades behind the front to produce strong or very strong winds during the early morning hours. Most locations along the west slopes of the Cascades should pick up 0.25-0.75" of water equivalent overnight. The front should bring significant cooling during the early morning hours into Wednesday with snow levels dropping to around 2000 ft for many areas with post-frontal snow showers. Convergence should develop north of Stevens Pass during the early morning hours, dropping gradually south to Snoqualmie by mid-morning and then fizzling as a weak ridge dries the region out Wednesday afternoon.
