Gary Lessor, meteorologist with the Weather Center at Western Connecticut State University, said Monday afternoon will be partly cloudy, hot and humid, with temperatures between 85 and 90 degrees.
-From Noon to Midnight for NW Burlington, Camden, Gloucester, Hunterdon, Mercer, Middlesex, Monmouth, Morris, Salem, Somerset, Sussex, and Warren counties. Do not cross flooded roadways - 6 inches of water is enough to knock someone off their feet, and 12 inches of rain can float a vehicle. Rainfall could be heavy enough at times to quickly flood roads and cause washouts, making them impassable.
After a weekend of good weather, local residents are being told to prepare for heavy rainfall and possible flash-flooding Monday.
By mid- to late-afternoon, however, strong instability will develop, allowing for scattered storms to develop, the forecast discussion said.
Although a tornado or two across northern Virginia is possible the main threats will be severe ( 60 mph) straight-line winds and very heavy rains. Flash flooding is also possible. You should monitor later forecasts and be prepared to take action should Flash Flood Warnings be issued.
Weather officials have issued flood warnings for portions of central and northeastern IL following weekend thunderstorms. Never attempt to drive, swim, or walk through flooded areas. We will see clearing skies Monday night into Tuesday. Expect more comfortable and dry conditions for Tuesday and Wednesday.
The trigger is an approaching cold front from the west.
It looks like an active weather day ahead for a portion of New England.
