This animation shows how large scale events distant California both vertically and horizontally can impact our temperatures and winds. Looking at this animation first notice the upper trough and upper ridge that are moving towards the Golden State from the west. Focus on the upper ridge which is a northward extending loop of upper-level winds at…
By WeatherFlow meteorologist Shea Gibson 10/6/20 This year has certainly shown a very active hurricane season, and it is not over officially until November 30th. We are currently in the Greek alphabet on Hurricane Delta, which has exploded in strength over the last 36 hours. As of 8AM Monday morning (10/5/20), winds were only at…
The Western United States has been sitting under a strong upper-level High-pressure system. So we have had a long string of satellite pictures that look like this (below). Hardly a cloud to be found. High pressure pushes the air toward the ground, resulting in descending air that warms and dries out. Also, each night as…
Once again the west coast has a dome of high pressure over the entire region. For the San Francisco Bay Area this dome of upper-level high pressure at ≈ 18,000 ft. has: 1. Crushed the marine layer to a patchy thin layer of fog. 2. Compacted all the smoke down to near the surface. 3. Created…
by Meteorologist, Kerry Challoner Anderson This week an unusually strong High-pressure system dropped out of the Canadian Plains into the Rockies. The center of the High trekked through Wyoming and Colorado bringing early season snowfall and setting off strong downsloping winds through the Wasatch Mountains of Utah. The storm had all the ingredients for a…
By WeatherFlow meteorologist Shea Gibson on 9/9/2020 We certainly had a tough time this year pronouncing the name “Isaias”, which led to several meteorologists stumbling over the name at least once or twice during discussions. But this also sparked interest in how these names are picked, what other names are on the list and how…
Weatherflow San Francisco Bay Area wind forecast by Mike Godsey San Francisco Bay Area forecast at 11:30 AM: Looking at over a dozen cams about the Bay Area and at the satellite imagery we see an apocalyptic scene filled with reddish smoke intermingled with marine layer fog. Streetlights are still on at 11 AM and…
by Matt Souders with graphics by Mike Godsey. This historic early-season easterly wind event got off to a dangerous start this morning. High winds over Yakima, WA fanned the flames over an 80 sq. mile wildfire. The smoke from that fire can be seen in this visible satellite loop arcing SW, then westward over the…
by Meteorologist Kerry Anderson California is seeing unprecedented heat this Labor Day weekend. Sunday the National Weather Service reported a temperature of 120 in Reseda. Meanwhile, the Santa Barbara shoreline barely broke into the 70s. Why such contrasts? First, we are seeing an astonishingly strong upper-level ridge over the area. Monday’s 500mb map (below) indicates…
By WeatherFlow meteorologist Shea Gibson on 8/30/2020 We have certainly see quite a bit of activity in the month of June, including a US landfall over western Lousiana by a major CAT 4 Hurricane Laura on Thursday, August 27, 2020. Many records have been broken this year with getting to early names in the alphabet…
