San Francisco Chronicle —
The last wet weather system of the week is poised to swing across Northern California on Wednesday, but it won’t pack much of a punch. Afternoon and evening rain showers are unlikely to add up to more than a tenth of an inch in San Francisco, while parts of the Bay Area could remain completely dry. Light snow should add another few inches to the northern Sierra Nevada snowpack, but the system will be starved of moisture by the time it reaches Lake Tahoe.
Beyond Wednesday, a weeklong dry stretch is likely in store for the Bay Area.
A gradual warming trend is expected Thursday through Monday, with widespread 70-degree temperatures returning Sunday and perhaps some 80s by Monday.
However, the early spring warmth doesn’t mean the storm season is done for good.
A majority of long-range weather models hint at rain returning to Northern California by the middle to end of next week. This will likely kick off a series of storms continuing through the end of March. Some data suggests that storms by early April could be even wetter than the recent rain and snowmakers, possibly tapping into a series of atmospheric rivers.
