The center of high pressure drifts from the Eastern Great Lakes into New England this weekend. Next week, it will be forced southward in response to Hurricane Willard headed into the Canadian Maritime region. This large airmass will control our weather through the entire 7-day forecast.
This weekend and Monday are more than 10 degrees cooler than average for mid-September with frost possible in deeper valleys. A gradual warming trend commences Tuesday, and we'll be back to seasonal averages by the end of next week. No precipitation is expected through next week; however, we will keep an eye on Tropical Storm Beta in the Western Gulf--a move in our direction by the end of next week is not impossible.
While all is quiet with our weather, the tropical Atlantic is still churning. Here's a look from west to east... Tropical Storm Beta is in the Western Gulf. It will hang out along the Texas coast and strengthen into a hurricane early next week. By Thursday, it will drift into Thursday. Because of it's slow movement, heavy rain is expected along the Western Gulf Coast. Hurricane Teddy is over 650 miles SE of Bermuda. It becomes a major hurricane soon and could affect Bermuda Sunday night before heading toward the Canadian Maritime region by the middle of next week. Tropical Storm Willard is in the Central Atlantic moving WNW. No significant strengthening is expected with Willard in the foreseeable future. The remnant of Paulette is near the Azores, and the next disturbance is now moving off the East African Coast.
