It’s been a very wet and ugly stretch of weather in the Northeast this week with some towns measuring over a foot of rain since it began to fall as early as this past Saturday. Flooding rains have been the story across southeastern portions of Pennsylvania while tornadoes sneakily struck a few towns about 30 miles southwest of Boston Wednesday night.
We finally have some good news to share with you for once, and that is that a nice weekend is in store for most of the Northeast thanks to high pressure briefly passing through behind a cold front. On Saturday, that front will cut right through the region, placing the Mid-Atlantic to the west and New England to the east.
Therefore, New England will have one more day of the humid weather as dew points generally reach 70 degrees in the afternoon. There will also be the risk for a few hit or miss showers and thunderstorms, especially across eastern New England, while a few spotty showers threaten the western half of the region and the northern Mid-Atlantic.
Besides that spotty, brief shower chance in parts of the Mid-Atlantic on Saturday, the day will be very beautiful with eternally sunny skies. The key difference is the humidity as dew points plunge from the 70s down to the 50s and low 60s, which is indicative of a drier air mass. Unfortunately, the coast will remain humid with those dew points holding at about 70 degrees. High temperatures will range from the mid to upper 70s inland up to the mid 80s closer to the coast and in the I-95 corridor.
Sunday will be a gorgeous day for all of the northeastern US as the cold front completely moves through the region, allowing for dew points to drop down into the 50s. Dry air and high temperatures between the mid 70s and mid 80s will be the story across both New England and the Mid-Atlantic. Skies will also be mostly sunny. A couple storms may be possible near the Canadian border and Great Lakes, however.
Unfortunately, showers and thunderstorms will return by mid-next week as a similar weather pattern redevelops. A trough over the eastern US and a large, subtropical ridge of high pressure over the Atlantic Ocean will funnel a multi-day firehose of tropical moisture up the East Coast, fueling days of heavy rain and storms. This will likely ramp back up the flash flood risk across parts of the Mid-Atlantic.
