When Is Bay Area Weather Going to Be Cold Again
Overnight freezing temperatures shattered several records this week ahead of a warming trend in the Bay Area over the weekend and a possible storm could bring light showers to the Northward Bay.
Records for low temperatures were broken or equaled in a number of cities this week. Redwood City dipped to 31 degrees Friday morning time, tying the lowest temperature e'er on Feb. 25 set in 1931.
Richmond had a tape low Thursday, with a temperature of 35 degrees compared to the previous record of 36 degrees in 1955, according to the National Weather Service. Records were likewise broken for Santa Rosa, which had a depression of 26, beating out the last record of 28 degrees in 2018. In downtown Napa, it reached 25 degrees, breaking the record of 28 in 2018. Redwood Metropolis equalled its previous tape of 30 degrees in 2018.
Marking the third day of sub-freezing temperatures, lows Friday were in the 20s along the interior portions of the Bay Area, with other parts outside of San Francisco getting into the 30s. A freeze warning and frost advisory remained in outcome until nine a.1000. Friday. San Jose dipped to 34 degrees Friday morn while San Francisco had a depression of 41. It was expected to warm up into the 50s and lower 60s across the region as the cold air mass starts to movement e and loftier force per unit area builds over the eastern Pacific Body of water.
Saturday is expected to be similarly dank, with lows in the 30s and highs in the 60s. It could start warming up by Dominicus, with some parts of the Fundamental Coast climbing into the low 60s, with lows in the 30s and 40s during the morning time. A mid-to-upper level trough is expected to push into the Pacific Northwest, bringing more deject cover. San Jose is expected to take a low of 44 degrees and a high of 68, while San Francisco could encounter a low of 48 and loftier of 62.
The North Bay could see "very light pelting" — well-nigh a 10th of an inch in northern Sonoma Canton and a couple hundredths for the balance of the area — belatedly Sabbatum into Lord's day morning. However, it looks bone dry in the forecast for the residuum of the Bay Area, making a "Miracle March" less likely. Loftier force per unit area will continue to dominate the atmospheric condition pattern, pushing any potential storms into the Pacific Northwest instead of hitting the Bay Area. The pattern is typical of a La Niña occurrence in the Pacific Ocean, in which cold h2o rises and leads to droughts in western parts of the state.
"The ridge that'south set over the northeastern Pacific has been pushing the storm track to the due north, and then information technology looks similar it's breaking downwards over the weekend, which is going to permit some wet atmospheric condition into the Pacific Northwest," said forecaster Jeff Lorber. "That's skilful news for them only for united states of america, it doesn't look like we're going to become any or much of that moisture. We would need a deep trough to develop over the expanse to get some wet weather over here and the current pattern doesn't wait conducive to that."
The storm earlier this calendar week marked the first measurable rain to hit the region since early on Jan, putting an end to a long dry spell and dropping around a tenth of an inch of pelting across the Bay Area. Widespread hail was also reported, pulverization reaching the tops of the highest elevations in the region. Chews Ridge in Monterey got at to the lowest degree half dozen inches of snow.
The storm also dumped snow on the Sierra Nevada. Equally of Midweek morning, it snowed 22 inches at Homewood, 21 inches at Kirkwood, 20 inches at Northstar, 18 inches at Sugar Basin, 17 inches at Palisades Tahoe and Carry Valley and xvi inches at Dodge Ridge.
Going into its third year of drought, California is facing increased wildfire take a chance and a depleted water supply heading into the warmer months. Atmospheric river storms in Oct and December built up the statewide Sierra Nevada snowpack to 168% of normal on New year's Twenty-four hours and marked the 21st wettest December on record for San Francisco, which has climate records dating back to 1849. Past Th, the Sierra snowpack had dipped down to 66% of normal, according to the California Section of H2o Resource.
The state'southward drought severity has also worsened during this bout of dry out weather. California's "extreme drought" — the 2d well-nigh severe type of drought designated by the U.Due south. Drought Monitor — went from 1.39% on Feb. xv to 6.7% on Feb. 22, marking a 5.31 point modify.
"In that location'due south too much incertitude at this betoken to say," Lorber said. "The extended outlook is looking fairly dry into the first half of March, and so it'due south not looking promising. Typically, March is one of our wetter months and the concluding month of our official moisture season. If we don't get anything in March, and so it'south non going to be adept once we become into Apr and transition into the dry out season. Burn down concerns will be heightened at that point, as they already are given our extremely dry out past couple of months."
