The Lehigh Valley is under a flash flood watch until Monday night, but forecasters noted that the threat of widespread, significant flash flooding has diminished.

Showers and storms could impact the area Monday and lead to areas of flash flooding, according to the National Weather Service in Mount Holly, New Jersey. Flooding could happen in urban areas, rivers, creeks, streams and areas with poor drainage. Any areas that had flooding Sunday night could also be at risk again Monday.

“Otherwise, it`s also worth noting that it will not be getting quite as unstable this afternoon due to much of the area being ‘worked over’ by previous convection and mainly cloudy skies,” meteorologists wrote Monday in their daily forecast discussion. “This will limit the risk of severe weather.”

The flash flood watch ends at 8 p.m.

Less than an inch of rain is expected, however there could be more during thunderstorms, forecasters said.

There will be a lull in the rain before showers become more widespread in the afternoon. The weather service said the heaviest rainfall will likely track near New York City.

The rain Monday comes after a dayslong period of intense heat and periodic storms in the Lehigh Valley that knocked out power to thousands. A high of 101 was recorded Thursday, marking the hottest day of the year for the region. Temperatures stayed in the 90s until Sunday, when they dropped to the 80s.

Highs will be in the 70s and 80s this week. Showers could linger into Tuesday, and there could be more rain over the weekend. Here is the extended forecast from the National Weather Service:
