Weather Synopsis for Tuesday & Wednesday
Tuesday looks warm and rainy in many locations across the forecast area. Nearly all of our weather stations report above freezing temperatures this morning, with several spots in the mid and even upper 40s. Light to moderate rain should spread further southward as a slow-moving warm front finally meanders its way across and out of the area. The bulk of the precipitation during the day should stay north of Mt Rainier and west of the Cascade crest. A break in the rain appears short-lived this afternoon as a trailing cold-front swings from NW to SE. Don't let the word "cold" get you too excited. While snowlevels will drop slightly with this second round of precipitation, many areas will continue to see mostly rain. Only the highest peaks and locations closest to the Canadian border should expect any snow on Tuesday. Showers overnight will reach nearly all trailheads, including those lucky few locations that missed out on rain during the day.
Expect shower activity to taper off Wednesday morning as colder temperatures finally return to the Olympics and Cascades. Sufficient low-level moisture and westerly winds could ring out a few snowflakes along the west slopes of the Cascades and put a dusting of snow in the trees Wednesday.
