Tuesday Discussion

Two main features on this morning’s weather map: a large high pressure system now south of us and a large-scale thunderstorm complex across NW PA. This high pressure system will move off the east coast by tomorrow and will set up as a “Bermuda high” pumping hot air into the Mid-Atlantic region for the next couple of days. Temperatures will soar well into the 90’s from DC to NYC tomorrow and Thursday, but then a cool front will slip through on Friday starting a downward trend in temperatures for the weekend.

Meanwhile, the large-scale thunderstorm complex that is across NW PA this morning will track to our southwest and should slowly weaken as the day progresses. Nonetheless, some high clouds are likely around NYC and an isolated afternoon or early evening shower or thunderstorm cannot be ruled out; especially, to the west of NYC. Once the cool front slips to our south early this weekend it will stall out and this should lead to some unsettled weather with showers and thunderstorms possible in the Mid-Atlantic both Saturday and Sunday.
