Forecast discussion: At the moment, high pressure centered over western Ohio is controlling the weather pattern over eastern Massachusetts. As we head into the beginning of November, two low pressure systems will bring showers, rain, and strong winds for the weekend to Boston.
At the moment, the first low is currently moving out of Michigan. The second low will be gaining strength as some upper level dynamics move over Georgia and Florida. The strong coastal low will not intensify until Friday morning. For us, we will see mostly cloudy skies as our kids turn into ghosts and goblins. The actual trick-or-treating will be dry, but temperatures will be falling into the upper 40’s. So, a light jacket might be needed under the costumes.
We will not begin to feel the effects of the coastal low until Saturday morning. Winds will be getting stronger, and we will have wind gusts as high as 40-50 mph. The Cape and Islands may see wind gusts as high as 60 mph. We will also see showers Saturday morning become heavier during the afternoon. The precipitation will taper off into the evening, as the low begins to move away from Southern New England. There is the slight chance west of Boston may see the showers turn or end as snow showers early Sunday morning. Also, frost warnings or freeze advisories may be needed Sunday night, as overnight low temperatures could stay at or slightly above freezing.
The low will still provide us with some strong winds on Sunday, as high pressure to our west tries to build in over New England. As the high slowly begins to take over the weather pattern on Monday, the low will move into Nova Scotia, allowing for winds to slowly diminish. Also, warmer air from the south will slowly return back into the Northeast U.S. We will return to seasonable conditions on Tuesday. Temperatures will actually be slightly above normal on Wednesday, as we could reach the lower 60’s.
We will return back to gray skies on Thursday, as we await a new cold front to pass into New England. Thanks to the warmer temperatures, the precipitation will remain rain showers. There is a small chance the front will stall, giving us showers into part of next Friday.
