That upper-level-low has shifted east, as in currently over the Gulf of Maine. Behind this we have high pressure building in, this will stay in control through the day tomorrow.
The high will keep that other upper-level-low to our west providing a stellar weekend. Today will feature plenty of sunshine with seasonal temperatures. Saturday will see clouds increasing ahead of the next disturbance. For both days, the vast majority of y’all should stay completely dry, but there will be the chance for a couple of very isolated rain showers. This will give the areas that saw the significant rain and flooding a chance to dry out.
We become
unsettled for Saturday night and Sunday as that western ULL moves into the Ohio
Valley, our rain chances increase ahead of a slow-moving cold front that will
approach and move across the region from the north. The high pressure will allow
for southernly winds to pull in higher dewpoint as well as temperatures getting
a little higher. Showers and storms should be isolated to scattered.
With the
higher humidity, storms will be capable of torrential downpours. With all the
rain of late, given the heavy rain isolated flooding. Showers and thunderstorms
will become more numerous and widespread likely later Sunday into Sunday night.
The rain and thunderstorms will continue for Monday. For Sunday and Monday
there is a chance for a few storms to become strong to severe, capable of producing
damaging winds and localized flash flooding. The SPC has a Moderate Risk across western Maryland, Pennsylvania, and New York State.
Much of the region will be dry to mostly dry for Tuesday and Wednesday. But with the front stalled somewhere south of the Mason Dixon Line over the Middle Atlantic, Southern Pennsylvania, Maryland, Delaware and southern New Jersey. Low pressure moving along the boundary, will allow for waves of scattered showers and thunderstorms over these areas. The farther north you are away from the boundary the less your chance of seeing the rain and storms.
The trough
hangs around for Thursday, giving the chance for isolated showers. Then on
Friday another cold front moves across the region, bringing the chance for
scattered showers and a few thunderstorms. Right now, these storms look to be
non-severe.
