Forecast discussion: A ridge of high pressure coming out of Canada helped give Boston bright sunshine on Tuesday. We continue to have low humidity, and our overnight lows remain seasonable. However, thanks to winds shifting to the east, our high temperature in the capital city was only 72 degrees. Unfortunately, there is no major heat wave coming to New England in the next seven days.
A stalled low pressure system off the coast of North Carolina will remain to our south, as many computer models now agree that the strong ridge will protect us. However, some moisture from a low over Michigan will bring increasing clouds by Wednesday afternoon. Also, winds will shift to an easterly wind, which will help keep temperatures slightly cooler. We will see a pattern of seeing mostly cloudy skies at night, and by Friday, we will see limited sunshine.
The low offshore has been shown by the models in recent days to return back to southern New England over the weekend, due to a blocking pattern in the upper levels of the atmosphere over the northern Atlantic. However, it seems now the ridge will keep the low to our east, so we will see limited sunshine and cooler temperatures through the weekend. In fact, high temperatures will only reach the lower to middle 70’s. But, winds will begin to turn back to the southwest, helping to increase our temperatures back to seasonable levels by next Tuesday.
