St. John Valley weather for Aug. 8-14, 2018
A weak cold front will slowly move across the region Wednesday into Thursday before being pushed eastwards by a stronger cold front Thursday evening into Friday morning. Behind the second front, cooler, drier air will build in on Canadian high pressure for the weekend into the start of next week. A low-pressure system from the Ohio Valley brings a chance for showers Tuesday.
