Apex Weather

SJV Weather for Monday, June 12, to Sunday, June 18, 2017

A warm front will lift across the Valley Monday afternoon and evening as a weak disturbance moves from the west into the state setting the stage for showers and thunderstorms during the afternoon and evening. Some isolated severe storms are possible with gusty winds and small hail.

A cold front moves through the region early Tuesday followed by a strong Canadian high building in, which brings mostly clear to partly cloudy skies and cooler conditions Tuesday through Thursday night. A low-pressure system in Canada draws a warm front towards the Valley, producing a chance for showers Friday and Saturday with disturbances aloft creating chances for thunderstorm activity Saturday night into Sunday morning.

A cold front approaches later Sunday with another chance for showers and thunderstorms Sunday afternoon/evening.
