San Francisco Sees Rainiest Day in Ten Months

SFO

It’s been a while since San Francisco saw a good, soaking rainfall, but Sunday brought a much-needed soaker for the city by the bay.

San Francisco’s airport recorded 0.76″ of rainfall on Sunday in association with a strong band of wind-driven stormy activity during the morning, leading to a 37 mile-per-hour (MPH) wind gust as well. The 0.76″ of rain made it the rainiest day in the city since February 8th and the second-rainiest day in the city so far in 2015.

While Sunday’s rain helped, San Francisco is still in a significant drought. Huge rainfall deficits in the last three years have culminated in a brutal 2015 as well, with the city seeing just 6.63″ of rain so far this year (including Sunday), well shy of the year-to-date average of 17.99″, meaning San Francisco has seen just 37 percent of its typical annual rainfall.

The Sierra Nevada mountains received significant snowfall from this system, with higher elevations getting more than two feet of snow, which will help with snowpack levels hovering about 50-60 percent of average of where they should be this time of year.

Unfortunately for the Bay Area, it appears that it won’t rain again for a little while. The work week is expected to feature plenty of sunshine with temperatures topping out in the 50s, although rain is possible again next weekend. A strong El Niño, however, should increase chances for a wetter-than-average January through March in the area as the subtropical jet stream gains extra energy due to warmer-than-average Pacific Ocean sea surface temperatures.

Stay with WeatherNation as California prepares for possibly more significant, El Niño-driven rainfall during the second half of the area’s wet season.
