Heavy Rain Producing Flooding in the Northeast Heavy rain has been falling over parts of the Northeast this weekend and more rain is ahead today (Monday). Nearly 2" fell Sunday at JFK airport in New York, setting a record for August 12. Some areas of Pennsylvania have seen excessive rainfall this morning that could lead to additional flooding. Flash Flood Watches extend from southern sections of New York into northern Virginia. The Weather Prediction Center says there is a moderate chance for flooding in that area, with a slight risk from southern New York to Chesapeake Bay. https://twitter.com/NWSWPC/status/1028941660275830784 Some areas may see up to 6" of rain into Tuesday. Heavy rain will be isolated, but with over-saturated soil, flooding is possible. There is also a marginal risk for severe thunderstorms. The low pressure center has moved offshore into the Atlantic Ocean. With high humidity sweeping over a warm front and wrapping around the low, significant rain is possible behind the low. As the low pushes away Tuesday, the threat for heavy rain will diminish. For WeatherNation: Meteorologist Mace Michaels
