Forecast discussion: It seems depending on what part of the country you live in, it has becoming a period of weather extremes. In California, they desperately need rain. In Texas, all they have seen is rainfall. Some areas have seen 20-25 inches this month alone. Meanwhile, in Boston, we are now in a moderate drought. We are almost 5 inches below normal before we come into June. Unfortunately, except for a few chances over the next few days, rain will be tough to come by as we leave May. It does not help when the high temperature for the day is 86 degrees.
A strong Bermuda high pressure system has been giving us dry, sunny weather for the last several days. However, with the south-southwest winds continuing, it will be more tropical air into the region. This will help raise our dewpoint temperatures, so the humidity will be increasing and remain humid into Friday. With the high dewpoints and the ocean temperature in the middle 50’s, expect patchy to dense fog along the coastline for the next few overnights.
As we head into the next few days, we await a cold front that has been punishing the Southern Plains, as it keeps creating rain, thunderstorms, and some tornadoes. The front will slowly move eastward, and we will see an increased risk for afternoon showers and thunderstorms. The next chance to seeing scattered showers and thunderstorms will be Thursday night, as the cold front passes through the region.
High pressure will bring some drier, less humid air to us by Friday. The high will influence us into Saturday afternoon, before a new cold front passes through New England. We will see a line of showers and possible thunderstorms right around midnight and through most of the day on Sunday. We will see clear skies by Sunday night, along with some cooler temperatures. The upper level ridge over the eastern U.S. will break down, allowing for cooler air to come into the area. High temperatures early next week will only reach the upper 60’s.
