Weather Synopsis
It's another very warm and sunny spring day across the region. Most weather stations are reporting temperatures in the mid to upper 50s, with a few hitting 60F! Wow, that's hot! High thin clouds and easterly winds are most pronounced from about I-90 south along the spine of the Cascades. A high pressure ridge parked over the Pacific Northwest should keep us dry from most, if not all, of the week.
Sunday night will be mostly clear with a few high clouds. While temperatures will cool, they should stay well above freezing. Weak inversions may form in the mountain valleys and passes, but even these spots won't dip below 32 F. Expect easterly winds to gradually decrease and turn SW-W overnight. The Passes will be the last to hold on, but should also shift to westerlies in the early morning hours.
A storm system passes to our north on Monday, causing the high pressure ridge to bend but not break. The most noticeable difference will be the increasing winds. Look for gusty westerly winds to strengthen throughout the day. With onshore (west) flow, temperatures east of the Cascade crest could peak several degrees warmer than they did over the weekend. All forecast zones should once again see 5000ft temperatures topping out in the 50s or even nipping at 60 F.
Low and mid clouds may arrive very late in the day or right around dinner time as the storm passes along the Canadian border. There could be a few sprinkles or flurries, but they shouldn't amount to much, and likely won't even register at the weather stations. Winds continue to increase Monday night as colder air moves into the region. Freezing levels should dip low enough to allow most trailheads to drop to near or just below freezing.
Sunshine and lighter winds return on Tuesday as NW winds usher in colder, drier air into the area. This will mark the start of a long, gradual warming trend through the remainder of the week.

Extended Weather Synopsis
The high pressure begins to rebound Tuesday night. With the ridge overhead and a cut-off low pressure further south, a Rex Block pattern is established over the PNW. Named weather features like this often spell persistent periods of drier weather. And that's exactly what's in store. Freezing levels and daytime high temperatures gradually rise as the upper air winds shift from NW to W. Expect plenty of sunshine and very spring-like weather across the region.
