A severe thunderstorm watch has been issued for parts of MA on Monday.
A very strong line of thunderstorms is already moving eastward and multiple severe thunderstorm warnings have already been issued as well as one tornado warning for Lancaster County.
The storms could bring damaging winds, hail and flash flooding, the National Weather Service says.
Torrential rainfall is occurring with this storm, and may lead to flash flooding.
A severe thunderstorm watch is in effect for all five boroughs, Long Island, and these areas in New Jersey and CT.
Any severe weather is likely to occur in the time frame of 2 p.m.to 10 p.m. Areas near Phoenix could hit 120 degrees Fahrenheit Monday afternoon. Rainfall amounts of 1 to 2 inches are possible with localized totals of 3 to 5 inches possible. Flash flooding is a very unsafe situation.
“Increasing thunderstorm activity is expected into and through the 1 to 4 p.m. time frame, accompanied by a risk for potentially damaging wind gusts”, the storm center said.
A heavy thunderstorm pelted central NY with golf ball-sized hail last month, with thousands losing power from the sudden high winds.
“Isolated tornadoes and locally large hail are also possible”, according to the National Weather Service.
By daybreak, the shower threat should end and skies should clear out early on Tuesday.
