Observation Date Observation Time Precipitation Snowfall Snowfall SWE Snow Depth Snow SWE Notes
10/1/2011 8:45 AM 0.00 0.0 M M M Partly cloudy, 59, muggy. High was 70
10/2/2011 10:00 AM T M M M M Partly cloudy, 62. Sprinkles at 4:05pm & 11pm enough to use wipers. On way to Olema in Marin CO. Hit a fairly good shower about 1/2m out of Tomales at 4:30pm. As I drove down Hwy 1 along Tomales Bay I could see a downburst that looked to be about Pt. Reyes Station & Oleama. When I reached Pt. Reyes Station it was wet, but not coming down then. When I arrived to see friends at Olema Campground they confirmed that about 4:45 or so they had a brief intense downpour. Then it became partly cloudy and was great weather for our campfire, barely a breeze as we visited until 10pm. Didn't hit any rain on the drive home until reach my neighborhood as mentioned above.
10/3/2011 7:15 AM 0.00 0.0 M M M Partly Cloudy, 53, yesterday's high 72. I and my roses are waiting for promised rain.
10/4/2011 7:15 AM 0.51 M M M M Cloudy, light mist and 54. High of 60. Very nice rain to start off the season with .40 in guage by 5pm. Amount should probably be higher as my Flowering Maple was partially blocking guage. Trimmed one branch off this morning. So I will see if this is enough. It really grew this summer & humming birds love it so didn't want to trim too much.
10/5/2011 7:15 AM 0.89 M M M M All but .10 of this fell after 6:30pm. It is clear and cool 49 currently with some clouds to the west I think through the trees. High of 62. Supposed to be thunderstorms later on. Yesterday going to Tomales @8:20am hit almost dense ground fog on Tomales - Two Rock Rd. just after Twin Bridges Rd. It stayed that way almost to Hwy 1, and then it lifted up some.
10/6/2011 7:15 AM 0.11 M M M M Partly cloudy looks like it is clearing. I hope so since going with two 3rd grade classes to Bouvrie Nature Preserve in hills east of Glen Ellen and will be outside most of day.
10/7/2011 7:15 AM 0.04 M M M M Partly cloudy, clearing 48. This is from light showers from a passing cloud or two late morning. I estimate a bit more, maybe .11 fell while we were at Bouvrie Preserve. High of 74.
10/8/2011 7:15 AM 0.00 0.0 M M M Clear looks light going to be a nice day, of course since I have to work.
10/9/2011 8:15 AM 0.00 0.0 M M M Foggy and gloomy, 60.
10/10/2011 7:15 AM 0.00 0.0 M M M Overcast and foggy warm 56. Light afternoon showers predicated but already light frizzle / drizzle.
10/11/2011 7:15 AM 0.39 M M M M Overcast, muggy still and already 58. Light rain / drizzle most of day until about 2:30pm with yesterday also muggy, UGH!
10/12/2011 7:15 AM 0.00 0.0 M M M Overcast 56 out. Yesterday 75. Was out in Tomales yesterday am and has anyone else noticed that with our rain last & this week we have the present of greening hills? Anywhere the fields & hills have been grazed on are now being carpeted with emerald green new grass. I know the rain isn't good for grapes & other crops, but it is great to have green instead of brown hills.
10/13/2011 7:15 AM 0.00 0.0 M M M Partly cloudy with high thin clouds and 51. High was 83.
10/14/2011 7:15 AM 0.00 0.0 M M M Clear calm 52, yesterday a warm 88.

Even with wind vents covers over car windows, sand was being blown in and deposited on dashboard and other places. Later up at Duncans Landing there was a coupla of good thundering waves that splashed salt spray and moisture on car. For people outside vehicles it was like a light rain as waves crashed.

Had to go to Geyserville abt 3pm and it was about 106. It was probably hotter by 5 or 6pm. Local paper Press Democrat says Cloverdale was 109 and Healdsburg 105. Geyserville is 1/2 in-between. Tv news said Santa Rosa was 104 or 103 depending on channel & broke a record, Pd says 97 and it didn't. It probably depended on if you were downtown (hotter with pavement & Rincon Valley on hotter eastside) or in cooler areas. I know the downtown bank display said 96 at 11:15am.

The Santa Rosa / Rohnert Park area is at 67% of normal compared to last year 2011at 119%. The hills are more the color of Sept. or Oct's golden, brittle color and it is only June. When you walk in non-watered grassy areas it crackles and crunches due to less rainfall, hardly any of our normal June gloom; warm and dry low humidty days. Hopefully people will be careful with the upcoming 4th of July and our summer extra dry season.

8/11/2012 9:15 AM 0.00 0.0 M M M Bright & clear 58 out with yesterdays high of 89. The nice thing about this recent heat wave is unlike when we have an off-shore event it, this & most other ones this summer have allowed the coastal breezes to come at night cooling us back down to the 50's. So this makes it bearable since you know about 5:30 to 6pm the coastal breezes coming in thru the Two-Rock / Tomales gap are going to reaching here. Thank goodness for the air conditioning provided by the Pacific ocean even though as the crow flys we are aprx. 18 miles inland.

9/29/2012 9:15 AM 0.00 0.0 M M M Fog is still in & it is 50 out. Yesterday was not hot as they predicated. The fog didn't clear in north Santa Rosa till after 11am so I am estimating it cleared here in Rohnert Park between 12:30 & 12pm since I could still see the fog over RP from where I was in north SR while it was clearing in SR. So it only made it to 71. The fog was pouring in along Tomales gap &ridge of hills opposite the Cotati grade already at 4:30pm.By 6pm it was also pouring directly east over the coastal hills in It's 2 pronged advance. Fog was completely in by 6:45pm.
