Detailed Discussion

This past weekend left many wondering – what happened? June arrived in the midst of summer heat, but by the time we woke up Saturday, mid-April was back in place, and it appears we’ll remain in a cool, April showers mode through much of this week. What did happen? The heat migrated west to the northern Plains and Prairies of Canada, and high pressure strengthened to our east over the North Atlantic. This left room for a pool of cold, unsettled air to drop in right over us, now trapped between the two high pressure systems to our west and east. The surface weather maps show a storm over the western Atlantic drifting northwest toward us, and high pressure building again over over Hudson Bay. The expectation is for the ocean storm to continue north toward the Bay of Fundy between Maine and Nova Scotia by midweek, while the cold high takes its time sliding east through northern Quebec, pushing a cold front south as the leading edge of the colder air. As the ocean storm drifts north, this morning’s showers through NH and far eastern VT will decrease this afternoon, followed by some partial clearing tonight. At the same time, the cold front settles south, with a few stray showers in the St. Lawrence Valley late today, drifting south into eastern NY tonight. Another note – wildfires in Quebec may also send smoke into portions of the region, especially west of the Green Mountains, a situation we will continue to monitor. Tomorrow, moisture pivoting around the storm to our east brings more clouds east and north of I-89, with showers increasing tomorrow afternoon, while clouds increase west and south, with a stray shower possible later in the day. From Tuesday night into Wednesday, the storm to our east near Nova Scotia strengthens, sweeps clouds over the entire region, with showers becoming likely through northern areas, more scattered south, but the clouds and showers will suppress the temperatures, in the low 60s south, and only the 50s to near 60 north. For Wednesday night into Thursday, the storm appears to stall just to our east, which keeps showers in the forecast, more so in eastern areas closer to the storm, but the placement of the storm will be critical to the location and extent of the clouds and showers. A westward shift in the storm’s circulation would increase the showers, and keep temperatures even cooler. By Friday, the storm is forecast to weaken, which would decrease the showers, and permit more breaks of sun. Again, those details will be dependent on the evolution of the storm through the week. The cool temperatures and rain showers should leave light to moderate amounts of rain, effective in helping short term soil moisture.
