Showers to Ruin the Weekend from New York to Virginia

The arrival of showers and thunderstorms on Sunday will prevent the weekend from ending as nicely as it started from New York state to Virginia.

Sunshine and low humidity are currently gracing much of the Northeast and mid-Atlantic this afternoon. Residents can thank an area of high pressure for the delightful weather.

The showers and thunderstorms that are now entering the eastern Great Lakes and rumbling over the central Appalachians are the reason today's nice weather will not last into Sunday.

Those showers and thunderstorms will continue to press eastward tonight, then will extend from southern Ontario and New York to Virginia on Sunday. At the same time, humidity will build over the mid-Atlantic.

Sunday afternoon will prove to be the wettest time of the day for Syracuse, N.Y.; New York City; Trenton, N.J.; Philadelphia, Pa.; and Dover, Del.

The area of high pressure will keep places in New England from Caribou, Maine, to Providence, R.I., dry and comfortable.

Monday is when the showers and thunderstorms will not only persist over eastern New York and the mid-Atlantic, but will also wet most of New England.

The main impact of the unsettled weather Sunday and Monday will be to put a damper on outdoor activities. The showers may force NASCAR officials to occasionally delay or postpone the race at Pocono Raceway Sunday afternoon.

Any flooding issues would be localized, and mainly confined to places that receive several rounds of showers and thunderstorms.

The wet weather Sunday into Monday will actually be beneficial to the Northeast and mid-Atlantic. The showers and thunderstorms will ease rainfall deficits.

The United States Drought Monitor reported Thursday that some places from eastern Pennsylvania and New Jersey to northeastern North Carolina were enduring a moderate drought.

The drought status has become severe across parts of southeastern Virginia. Richmond has only received 1.15 inches of rain this month. That is 25 percent of what typically falls each July.

An outbreak of severe weather is not expected Sunday or Monday. However, any thunderstorm that rumbles will spark dangerous lightning. If you hear thunder, you are close enough to get struck.
