This week we will see a possibility of an extended period of cloudy weather, punctuated by periodic storms. This regime will bring cooler than normal temperatures mostly in the low-80s. Good news: Labor Day weekend looks to be dry and cool so far! Looking to the tropics, we’re about to enter the peak of hurricane season, and it’s no surprise in this very active season to date to see that National Hurricane Center is monitoring four disturbances that could become tropical storms.

Rest of today – cool, generally cloudy with possible peaks of sun, high temperatures in the upper-70s. Temperatures will be cool due to a persistent onshore flow with an area of high pressure over the Canadian Maritimes and a slow-moving warm front/stationary front to our south. This latter frontal boundary may also spark some showers overnight, with temperatures dropping into the mid-60s.

Tuesday – the cool, cloudy trend continues with high temperatures again topping out in the upper-70s. Showers may occur periodically during the day. Overnight lows in the upper-60s with chances of showers continuing.

Wednesday – the cloudy, rainy weather continues, though temperatures may be a touch warmer around 80ºF. Chance for showers and thunderstorms. Overnight lows in the low-70s as the warm front finally pushes through.

Thursday – cloudy, with a chance for showers, and warmer temperatures in the mid-80s. Overnight lows in the mid-70s. Shower chances persist overnight.

Watching the tropics

Keeping eyes on the tropics, given that we’re about to enter the peak of the season (September) when oceanic heat content tends to be the highest, providing the greatest potential fuel for storms. There are four disturbances in the Atlantic that could become tropical systems, however, none of them are an immediate threat to the US mainland.
