A warm front will briefly spike Bay Area temperatures before cool temperatures return — still with no promise of rain for at least a week, according to the National Weather Service.
Starting Thursday around midday and through Friday, temperatures are expected to creep up to the mid- to high-60s across much of the region, said meteorologist Spencer Tangen.
Thursday’s expected high is around 66 degrees in the South and East Bay, with parts of the North Bay nearing 70 degrees. Those highs will jump up about 2 degrees on Friday.
The slow-burning warm front comes after near-freezing lows and daytime highs in the low 50s for the first half of the week, thanks to a cold snap traveling directly south from Canada.
But the warmer, sunnier weather won’t last: Starting Saturday, another cold front is expected to brew, Tangen said, bringing chilly temperatures on par with what the Bay has seen so far this week.
Notably absent? Rain. Although the cold snap this weekend will bring winds of about 20 mph along the coasts and chilly overnight lows, it’s not expected to be a particularly wet system.
Rainfall this season has so far lagged behind its typical totals. Santa Rosa scrapes 72 percent of its typical total for the season since Oct. 1, according to NWS, while San Francisco is at 62 percent and San Jose just 46 percent.
Meteorologists don’t expect a chance of rain until at least Valentine’s Day — and even that’s “hit or miss,” Tangen said.
“We probably won’t see very much moisture at all,” Tangen said.
