Let me "warm up" by showing you the latest cam shots at Mt. Rainier's Paradise Ranger Station at approximately 5500 ft, where temperatures are around freezing and it is snowing. You want to throw a snowball...no problem.
Or a Hurricane Ridge in the Olympics, at a similar elevation? Yes, snow is falling.
And Crystal Mountain is a winter wonderland:
Our friends at the Seattle NWS office even have a winter weather advisory for parts of the Cascades, warning of winter-like conditions and 4-8 inches of snow!
The temperatures over us are unusually cold and much more like the typical conditions of January. I can prove this using the marvelous upper air climatology capability available from the NOAA/NWS Storm Prediction Center. Here is the climatology of 500 hPa (about 18,000 ft) temperatures at Quillayute on the Washington Coast. Red shows daily record highs, blue indicates daily record lows and black is average. The black dot show this morning's observation.
Today is a virtually tie for the record low for this date, or any date in June. BELOW NORMAL TEMPS ANYTIME OF THE YEAR.
Over the lowlands, it will be a cool, blustery day with convection and thunderstorms. The latest visible satellite image shows a large fields of cold air with lots of convection ready to move into our region. Only portions of central Puget Sound, shielded by the Olympics, may escape the showery fun.
My graduate student, Connor McNicholas has developed a wonderful FREE weather app that collects pressures on Android smartphones and gives you all kinds of valuable weather information. We believe we can revolutionize weather prediction using dense collections of pressures from smartphones. We need folks to try this app (and it already has been evaluated by dozens of folks) to ensure it works well.
