Here is the lastest infrared satellite picture (Sat morning). There is considerable cloudiness over us right now from a weak frontal disturbance and even some light showers are occurring), but the main action will be Sunday AM as a strong system reaches western WA. Let me remind you that the whiter the pixel in an infrared image the cooler and thus higher the clouds.
Here is the forecast 24 hr precipitation ending 5 PM on Sunday. Pretty impressive precipitation after our drought...with .5 to 1 inches forecast over the mountains and windward slopes, and several tenths of an inch over portions of the lowlands. Even eastern WA gets some scattered precipitation, a fact that is of importance to agricultural interests there. Want to be dry?...go south of Portland or head to eastern Oregon.
There has been some talk about snow in the mountains, but until you are hiking about 7000 ft I don't think you have to worry about that...but it WILL be wet and windy. In fact, the winds will also pick up noticeably over the lowlands as well.
Several of you have asked for the latest situation regarding the coastal radar. The unit is now down for a retrofit for the new dual-polarization option--an enhancement that every NWS radar in the country will receive during the next year. It is hoped that the radar will come back on line during the next week and the data should be flowing for public use soon after that. A dedication is planned for later this month at the radar site. But the radar will still be missing a critical option...the zero degree elevation angle...which will allow the radar to see much farther and better, particularly at lower levels. Our radar will be the first in the nation to have this option and the NWS promises it will be operational by Nov 1.
Finally, any of you living in Seattle please take a look at the picture and info to the right regarding my lost dog. We took her to local dog sitter who lost the dog over NW Seattle...so keep your eyes out and let me know if you see her. Thanks.
Reminder: I am teaching atmospheric sciences 101--Weather--this fall at the UW if anyone is interested in taking it. Retired folks can do it through the Access program (something like $5) and others can take the course as a non-matriculated student (but they do charge)
