St. John Valley weather for July 27-Aug. 2, 2022
Three-day outlook: Wednesday-Friday
High pressure brings dry weather today. Partly cloudy skies with fair-weather cumulus are expected today into tonight thanks to an upper trough along the northern border region. Mostly clear skies are expected early Thursday.
A warm front brings increasing clouds Thursday afternoon with showers likely by evening and a chance for afternoon thunderstorms. Showers with a chance for thunderstorms continue into Friday. This morning’s Storm Prediction Center outlook for Thursday-Friday indicates that the region will be at risk for isolated strong/severe storms with gusty winds. However, at this time, there is uncertainty regarding the degree of instability aloft to support stronger storms.
Friday will see partly sunny skies with a chance for showers and thunderstorms as a cold front approaches. The front will move through Friday evening with high pressure building in from the Ohio Valley overnight.
