The late winter (Feb-March) maps shows how wet conditions were particularly unusual in the northern Rockies. Eastern Washington, Idaho, and western Montana had unprecedented large amounts of precipitation.
Mean temperatures from October through March? Cooler than normal over Washington and Oregon....no big surprise.
This week, a colleague at the US Army Corps of Engineers told me that the soils of our region are extraordinarily saturated....and that he was worried about spring flooding. Well, here is the latest soil moisture observations based on the GRACE satellite (measures moisture using its effects of gravity). The entire Northwest is WAY wetter than normal (darker blue colors).
A front is now approaching our region and there will be rain later this afternoon, tonight and early Sunday morning (see forecast precipitation for the 3 hr ending 8 PM tonight). So get out now.
Fortunately, the latest forecasts suggest drying from mid-Sunday through the middle of next week, and the latest NOAA Climate Prediction Center forecast indicates drier than normal conditions for much of the West Coast for the 6-10 day forecasts (see below). Time for me to try planting grass seeds again...
