The upper level ridge in the Atlantic holding pretty strong for today into tomorrow. This will force the upper low centered near Lake Erie right now to lift slowly northward and weaken today through tomorrow as it heads up into western Quebec. This will result in only a slow eastward push of the surface cold front that is stretched now from western New York through central Pennsylvania and down into Virginia. We will see a couple of rounds of showers and thunderstorms coming up from the southwest across the area today into this evening. The bulk of the activity from mid afternoon into this evening will tend to shift a little farther east as drier mid level air punches in from the west. It is unclear if we get into any more isolated activity in the city this afternoon or this evening, but viewers to the west probably will.
There will also be a weak wave of low pressure and moisture that comes northward in the Atlantic today to near Cape Cod tomorrow evening. This will also help to slow the front and result in lingering wet weather for a time tomorrow from the Dela.ware and Maryland Beaches up through eastern New Jersey and across Long Island and up through eastern New England. The front will also still be nearby tomorrow, but we think that punch of dry air from the west later today and tonight does keep the city dry tomorrow with some sunshine and a little lowering of the humidity. Upper level ridging behind this lifting trough and a bubble of surface high pressure building in Monday will keep us dry with more sun than clouds.
