Wednesday:
The Snapshot: Intermittent rain showers today
with another round of heavy rain tomorrow; cooler and drier by the weekend.
The Science: An upper-level ridge has brought an end to the main water tap with only intermittent
rain showers left over. The next front arrives
tomorrow morning with another fetch of warm moisture in tow. An additional 2-4” of rain will be possible. Freezing levels will remain high through mid
day on Friday.
4-7day Long Range: High-pressure developing in southern Canada will bring a pattern change starting
on Friday. Cold air will flow into the
PNW from the north over the weekend. Low
temperatures will likely cover everything in ice. A warm front (Monday ish) lifting up from the
south is starting to enter the scene. Hopefully,
this will mix well with the cold air and be our next best chance for snow.
