St. John Valley weather for May 8-14, 2019

Canadian high pressure brings cool, breezy conditions to the Valley this Wednesday and partly cloudy/mostly clear and cold temperatures overnight. The high pressure ridge will move east of the region Thursday with southerly flow developing that will allow temperatures to moderate. Clouds will increase Thursday night as a low-pressure system approaches with a chance for a soaking rain Friday. The low and associated cold front will move east of the region Saturday morning with decreasing clouds and precipitation chances in the afternoon. Partly cloudy to mostly clear skies are expected Saturday night through Sunday night with a mostly sunny, mild day for Mother’s Day. Clouds will increase Monday ahead of an approaching low-pressure system that is expected to bring another round of rain Monday night into Tuesday.
