4/8/2018 8:00 AM 1.85 M M M M A wet and wild day, yesterday. A deep low pressure system, very deep for this time of year, approached the PNW and curved up to Vancouver Island, which is a track favorable for wind.

Temperatures in the warm sector two days ago approached 70F, and were still around 60F the night before last. Temperatures dropped steadily yesterday and now sit at 47F this morning. Rain started late morning yesterday, and continued steadily all day and into last night. Before the rain came in the morning, the wind was blowing huge clouds of Douglas fir pollen all over the place. Very hard on the eyes! Winds very light now.

5/6/2018 8:00 AM 0.33 M M M M A dry, warm day yesterday, with variable clouds. A bit humid, as well. Big crash of thunder at 3:20 AM would have woken anyone from the dead. A lot more thunder, then rain, after that. Rain was showery then became more continuous. Rain stopped around 8 AM. I noticed from the map that I and observers right in the Corvallis NW area received quite a bit more rainfall then others in town or elsewhere in Benton county. Data density allows me to confirm that I am not in error.

2/15/2018 2/21/2018 8:00 AM 7 0.83 M M Just returned from a trip to Florida. Noted that there was an ice plug blocking the gauge orifice, but there was no precipitation in the funnel, so I suspect is formed just this morning and nothing was lost. 32F this morning.
