Weather

    Smoke from thr Park Fire has, for the first time, obviously made it to the surface of the west side of the Sacramento Valley. I can smell it and the Purple sensor reports above 170 AQI #ParkFire #CAWx #AirQuality

    The screenshot displays an air quality index (AQI) reading of 178 for Channel A and 177 for Channel B, alongside a historical graph and various particulate matter measurements. From the My Purple Air iOS app.

    The temperatures are in the 70s and it is quite overcast with clouds and smoke. So we took advantage of the fall-like weather and went to Black Butte Reservoir. Here are Western Grebes, a Double Crested Cormorant, a Robin, and an Osprey A group of Western grebes swimming in a body of water. The image is taken from a distance, showing the long, curvy necked  white and black birds spread out across the water’s surface. A cormorant flying low over a body of water with its wings outstretched. The water surface appears calm with gentle ripples, reflecting the bird’s silhouette. A red breasted Robin sits in a bush with red berries and green foliage. It has a speckled white and black face. An osprey, white and brown, is perched high on top of a utility pole surrounded by power lines. The background is a green orchard with some dry grasslands. Large trees with dark green foliage is visible on the left and right of the bird.

In the distance, plumes of pyrocumulous smoke rise into the sky, indicating a fire. The car’s side mirror is in view.

The clear blue sky is contrasted by pyrocumulus clouds in the background. A red curb in the foreground reads “NO PARKING FIRE LANE.” Trees

    Monsoonal moisture is invading the Northern Sacramento Valley. There are high level clouds now. Normally the wet bulb starts decreasing at daylight. Not today. People living in the South would shrug at 70° wet bulb but for me, it’s borderline intolerable. #CAWx Screenshot of a weather data table from mesowest.utah.edu, showing observations for 07/13/2024 at various times from 5:50 AM to 9:50 AM PDT. The table includes columns for time, temperature, humidity and wet bulb. It shows temperatures going up as humidity goes up resulting in ever higher wet bulbs. At 09:50 it was 86° with a relative humidity of 47% and wet bulb of 70.5°F.

    The highly unusual multi-day extreme heat of over 110°F took a huge toll on our Asian pears and nectarines. Worm food, now. #CaWx A cardboard box containing a mix of fruits, including pears and apples. Many of the fruits have dark, sunburnt spots on their surfaces. A single green leaf is also present among the fruits.

    In my part of the N. Sacramento Valley, 85 degrees F this morning. The humidity is 20% and it’ll drop. Temperatures may rise up to 113 today. Winds are still strong. Across the valley, at Oroville, is the Thompson Fire, which doesn’t seem to be letting up. #ThompsonFire #CaWx

    Compared to my old Intel 16” MacBook Pro, this M3 14” MBP is dreamy. As everyone reports, the battery life is ridiculously good. 76% remains and still 20 hrs predicted life. Oh, and I can use this as a _lap_top. Amazing. Funny part? I didn’t notice the lack of a touchbar. 📷 #MBApr A laptop displaying a web page with weather content, including a map showing a weather forecast. The laptop keyboard and touchpad are also visible.

    This is a slightly shorter post today for just Mosaic Canyon.

    Yesterday I picked up our wine club box at the New Clairvaux winery in Vina, CA. Couldn’t beat the weather! #Fujifilm A vineyard with dormant grapevines supported by trellis systems, numbered sign “34” in the foreground, clear blue sky above. Bare tree branches against a clear blue sky, dotted with round, brown seedpods or growths. A row of red brick buildings with closed white doors reflected in a large puddle on a sunny day. A red barn with an open door beside a large tree, with green grass in the foreground and solar panels in the background under a clear blue sky.

    Sun and rain! Thunderstorms are trying to develop. Maybe they’ll amount ri something on the east side of the Sacramento Valley. #CaWx Sunlight filtering through green leaves, casting a dappled glow on a wooden fence, with tiny airborne, slightly motion blurred, rain drops illuminated in the light.

    If the sun can keep breaking through the clouds today, we may see some thunderstorms in the northern Sacramento Valley… looking promising for weather nerds #CaWx A backyard with gravel ground cover, leafless shrubs, a few young trees, and a metal garden shed. In the background, there’s a house with a carport. There is also garden equipment scattered around, heavy clouds above suggesting impending rain. Puddles of rain and roofs are bright as sunshine has broken through the clouds.

    A quick storm today for the N. Sacramento Valley. I missed this in the forecast. We’ll actually start drying out for a few days tomorrow. 50°F right now, should get to 60° today. #CaWx

    The weather has been so damp that there’s been hardly any good time to prune. Since we’re finally drying out a bit, I went ahead and pruned our cultivated native grapes.  Sunday should be the warmest day, so I will likely prune the fruit trees then.

    Good morning from California, where Fall is finally reasserting itself.

    A backyard with a weather station and native plants. Early morning sunlight is reflecting off the bottoms of low clouds, resulting in a bright orange glow.

    Happy new water year! According to WeatherCat software, my wx station recorded a total of 27.91” for Oct 1, 2022 - Sep 30, 2023 water year. Compare that to 13.66” for Oct 1, 2021 - Sep 30, 2022 water year! Nature gave us a 0.5” boost yesterday. I’m in the N. Sac Valley #CAWx

    Weather was nice today! Summer is waning and so I guess outdoor photography season can begin. Here are a few dragonflies enjoying an overcast and hazy day. #Fujifilm

    An in-flight green dragon fly against a blue sky.A long view to the Northern California Coast range. It's a hazy and overcast day. Oaks and rolling golden hills are in front of some rugged mountains.Within a muddy area with green algae, a stick juts out and a red striped dragonfly rests at the stick's end. The insect has red patches at the ends of its transparent wings.

    I managed to write an ugly Python script that converts MesoWest (via Synoptic download; nice people there btw) CSV weather data to WeatherCat (macOS software) data. I did some QAQC and it’s a good conversion. I’m pleased. Nice to finally have locally stored & accessible historical weather data.
