The second half of the wet-weather system provided less rain for Sacramento than the first, with one-tenth of an inch of precipitation falling Tuesday.

Monday brought 0.21 inches of rainfall, totaling 0.31 inches of rain for the two days in downtown Sacramento, according to the National Weather Service. Though a gray blanket of clouds persisted in the Sacramento sky through Tuesday evening, the city saw the last of the rain in the early afternoon.

A few scattered showers continued in other regions Tuesday evening but wound down by the end of the day as the weather system straggled across Northern California.

For the entire storm, Blue Canyon received 3.42 inches of rain. There was 1.92 inches of rain in Grass Valley, and more than 3 inches fell in some mountain locations. Most Valley locations received less than a half inch of rain, and Redding Airport recorded 1.38 inches.

Today should be partly cloudy with a high around 90 degrees. Thursday's high temperature is forecast around 95 degrees and Friday around 100 degrees.

"All the stuff is going to dry up, especially in the Valley," said Johnnie Powell, forecaster for the National Weather Service. "Get ready for summer to come back in with a vengeance in July."

The brief spell of wet weather will increase stagnant water in the Sacramento region, which could lead to more birds and mosquitoes testing positive for West Nile virus, according to vector control officials.

"The excess water will increase mosquito habitats," said David Brown, Sacramento-Yolo Mosquito & Vector Control district manager. "As temperatures warm up by the end of the week, the virus will likely amplify and the risk of human transmission will increase."

There has not been as much West Nile virus activity as last year. Brown, however, believes the summer will likely bring increased activity.

In Sacramento, seven dead birds and 19 mosquito samples have tested positive for West Nile virus. One case of the virus in a person has been reported to the California Department of Public Health.

In Yolo County, two dead birds and five mosquito samples have tested positive for the virus.

In response to recent findings, district crews on the ground have started fogging with insecticide.
