After a wild morning of weather more storms are now pushing through New England. There is a severe thunderstorm watch posted for much of the area through 8PM. The morning storms, which spawned a small tornado in Revere, ushered in very warm and unstable air. Now a cold front is pushing east into the unstable air and building more thunderstorms.
As of this entry at 4:40 there is a tornado warning near Springfield. By the time you read this the warning may be lifted. But this give you and idea we are in for a volatile few hours.
Not everyone is going to see storms this evening. They won’t be as widespread as this morning’s rainfall, but if you do get a storm the rain could be equally as torrential.
The tornado this morning was the first recorded tornado in Suffolk since at least 1950. For weather history buffs, there is an account of a tornado ripping through the Charleston Navy Yard and East Boston on August 20th 1863.
Tornadoes are rare in New England and even less common along the coast where the influence of the Atlantic Ocean plays a role in limiting tornadoes. The cool ocean water often takes the strength out of thunderstorms before they can become severe enough for a tornado.
Nonetheless, tornadoes sometimes do occur even in cities. The storms this evening could be accompanied by small hail, damaging winds, torrential rain and yes even a small tornado, but this would be something that is highly unlikely, though not impossible.
The projected radar for 7PM this evening shows a few scattered strong to severe storms through eastern and central Massachusetts.
The best chance for the strongest storms will be northwest of a line from New York City to Plymouth Massachusetts. South and east of that line showers are still possible, but the likelihood of severe weather is far less.
A return to less humid conditions with more sunshine returns tomorrow for the rest of the week. The nights are also going to be much more comfortable for sleeping after this evening.
