Discussion
The very strong upper-level ridge of high pressure that has been parked overhead during the past few days is now weakening and shifting to the south. At the same time, surface high pressure has built into southeastern Canada and this combination has resulted in the formation of a back door cool front across northern New England which will push southwestward during the next 24 hours to a position in the southern Mid-Atlantic by late Friday. As a result, temperatures will be much reduced here today compared to the recent high heat and then it’ll turn even cooler on Friday as a low-level ocean flow of air develops behind the front (i.e., east-to-northeast winds).
There can be showers and thunderstorms from today into tomorrow during this temperature transition period and any storm that forms can be strong-to-severe. The back door cool front will then turn around on Saturday and push back to the north as a warm front resulting in quite warm and humid conditions on both Saturday and Sunday. There will be the chance of showers and thunderstorms on both weekend days, but neither should be a total washout.
