FORECAST
TONIGHT: WEATHER ALERT
Scattered thunderstorms
Lows: 70-75
Winds: South 5-10 mph
Scattered showers and embedded thunderstorms will continue to trek across the Mid-Atlantic with heavy rain that will increase the flash flooding threat. It is very difficult to know how deep water is over a roadway, especially at night, so remember to turn around, don鈥檛 drown.
TOMORROW:
Cloudy, areas of rain
Highs: around 85
Winds: South 5-10 mph
Slow moving, heavy thunderstorms continue through Monday with torrential rains continuing the flash flooding threat. It will be mostly cloudy, warm and humid, with locally gusty winds, frequent lightning and isolated flash flooding possible. Highs will generally be in the middle 80s.
TUESDAY:
Mostly cloudy, storm chance
Highs: 83-88
Winds: Southeast 5-10 mph
A mostly cloudy and dry day, but isolated showers and storms return overnight into Wednesday morning.
WEDENSDAY:
Partly cloudy, storm chance
Highs: 85-90
Winds: South 5-10 mph
A few more breaks in the clouds could lead to more sunshine and slightly hotter temperatures. However, this will likely further destabilize the atmosphere leading to additional chances for showers and storms.
THURSDAY:
Partly cloudy, storm chance
Highs: 86-91
Winds: South 5-10 mph
Partly cloudy for most, with isolated showers and storms by the afternoon. The nearby stalled weather maker will likely begin to move offshore by the end of the week, which could increase the threat for severe storms.
