Apex Weather

SJV Weather for Wednesday, June 28, to Tuesday, July 4, 2017

A weak low pressure will slip towards the Gaspé peninsula Wednesday with a trough trailing across the Valley, producing a chance for scattered showers into the evening hours along with a chance for thunderstorm activity until after midnight. Mostly cloudy to overcast skies become partly clear by Thursday with a slight chance for some late morning thunderstorms due to unsettled conditions aloft. A low-pressure system near the Great Lakes lifts a warm front towards the Valley later Thursday with a chance for showers as the boundary approaches in the evening/overnight period.

The front shifts towards the south as a cold front and stalls out Friday night before lifting northwards as a warm front once more later Saturday into Sunday producing showers and a chance for thunderstorms from Saturday afternoon through Sunday. The Great Lakes low finally lifts northeast into Canada pulling a cold front across the region Sunday into Monday with a cooler, drier air mass building in for Monday and Tuesday along with diminishing chances for shower activity by the Fourth of July holiday.
