St. John Valley weather for April 24-30, 2019
An area of low pressure in southern Québec this morning will slide into the Gulf of Maine this afternoon and move into Nova Scotia tonight. Light rain, moving southwest to northeast across the region, possibly mixing with some sleet in the morning, will continue into the afternoon hours as all rain before tapering to rain showers by the evening possibly mixing with light snow showers. A weak ridge of high pressure will build into the region as it slides by to the south of New England Wednesday into and Thursday with low-level moisture keeping skies mostly cloudy.
Low pressure from the Ohio Valley will approach with a chance for rain Friday into Saturday. Current projected rainfall in the 1.25 to 1.50 inch range is possible causing rises in area lakes, rivers, and streams once more. Low pressure moves by the Valley Saturday followed by a cold front Sunday with rain Saturday diminishing to showers Sunday, possibly mixing with snow showers Sunday morning. A small area of low pressure is expected to track from the southern Great Lakes later Sunday with a chance for rain spreading across the region Sunday night into Monday with some morning snow possible Monday. Rain is expected to continue Monday before tapering to showers Monday night. Longer-range models indicate high pressure building in for midweek next week.
