A late-spring storm swept the Bay Area Monday and delivered a dose of rain considered heavy for mid-May. The unsettled weather is expected to remain in the forecast through Thursday, with a short warm spell in store for the end of the week before another storm system arrives Sunday.

"It’s a little bit unusual to get these systems in May, but it’s not completely unheard of," said Anna Schneider, a forecaster with the National Weather Service office in Monterey.

The North Bay measured the most rainfall in the last 24 hours and a gauge at Middle Peak near Mount Tamalpais in Mill Valley recorded 1.84 inches.  Downtown Santa Rosa saw a half-inch.

Showers were lighter in the central Bay Area with Oakland measuring .13 inch, San Francisco Airport .03 and San Jose .04.

Lingering rain showers remain in the forecast through Thursday with the highest chances of rain in the North Bay. Temperatures will be below or near normal through Thursday with afternoon highs in the mid-60s to mid-70s in inland areas and in the 60s along the bay front and coast.

Dry weather will return late Thursday and temperatures will warm up a bit on Friday and into Saturday.
