Brief:

A large upper level cyclone over northern Ontario will control our weather for the balance of the week as it shifts slowly towards the lower north shore of the Gulf of St. Lawrence. Numerous disturbances whirling around its periphery will fling trough lines or weak fronts into our region and spark nearly daily rounds of showers and thunderstorms. Today, a robust disturbance starting the day over northern Illinois will rotate rapidly across the eastern Great Lakes to near Montreal by sunset. As it overruns a front in New York State it’ll spark lines of showers and thunderstorms that’ll propagate into our region. A few of these storms may pull down strong winds aloft, especially over the Adirondacks through the St. Lawrence, Richelieu, and northern Champlain Valleys.

Winds:

Today: Southwest to south 10-15 mph with a few gusts to 25 mph outside of any thunderstorms. Tonight: South diminishing to 5-15 mph. Wednesday: Southwest 10-15 mph with a few gusts to 25 mph. On the open waters of Lake Champlain, a Lake Wind Advisory is in effect. The National Weather Service forecast is for south winds 20-30 kts this morning, diminishing to 15-25 kts this afternoon, then increasing again to 20-30 kts this evening, decreasing to 15-25 kts after midnight and continuing so through Wednesday forenoon before diminishing further to 10-20 kts Wednesday afternoon. Waves 3-5 feet today, decreasing to 2-4 feet overnight through Wednesday morning, and to 1-3 feet Wednesday afternoon .
