The slow-moving storm that finally brought some rain to the Northeast is still causing showers from Maryland to Maine. New York City was hard-hit by a batch of heavy rain late this morning, but at most places the rainfall totals were far less than in yesterday's deluge.
As the storm departs tomorrow, it will turn warmer, with afternoon temperatures taking a run at 70 in Boston and 80 degrees in Philadelphia. The warmup will be reversed as we go into the weekend. A cold front that will cause showers and thunderstorms around Chicago later this afternoon and tonight will reach the I95 corridor by Saturday morning. A second cold front will cross the Northeast on Mothers Day. That front will have far less rain than the first front, and it will actually usher cooler and much drier into the Northeast late in the weekend. This video has more.
Last evening, there were showers around much of central Pennsylvania. In this picture, Sam the Dog surveys the back deck as it continues to dry out from previous showers. Sam is a 13-year-old American Eskimo Dog, and I believe he still enjoys growing additional fur.
Early this morning, the most concentrated rain was falling in a band from Maryland to southern Michigan.
With a high pressure area over Maine, a low pressure area over western Indiana and an upper-air storm spinning over the western Great Lakes, the stage is set for wet weather in the Middle and North Atlantic states.
This map is a rainfall forecast from the NWS Middle Atlantic River Forecast Center located in State College, PA.
The upper-air flow forecast for this evening shows the trough that helps to support rainfall ahead of the cold front.
After reaching the 80s today from NYC to Boston, it might not be that warm again through much of next week.
A noticeable push of cooler air will spread southward from Ontario and Quebec into the eastern Great Lakes and New England between tomorrow and Saturday.
