You can swim through the air on the East Coast this afternoon. It’s a typical hot, muggy summer afternoon, and an approaching cold front is allowing this soupy air to explode skyward and trigger some nasty thunderstorms. It looks like the storms will arrive in the megalopolis just in time for rush hour, of course.

A line of thunderstorms rolling into the Northeast has the potential to produce wind gusts to 70 MPH and hail to the size of ping pong balls as they move through. A severe thunderstorm watch is in effect ahead of the storms, which could impact the heavily-populated I-95 corridor around rush hour.

Nature has a twisted sense of humor.

Southern Rains Will Lead to Weekend Snow in New England, I'm So Sorry

The thing about March is that it lures you in with springlike temperatures, chirping birds, bumbling bees, and just when you start to let down your guard—WHAM!—you get smacked with a winter storm. It happens almost every year, but I am so sorry to say that it's probably going to snow this weekend.

Much of the eastern U.S. is about to plunge into the coldest wave of Arctic air we've seen this winter, and for many, it could feature more sustained cold temperatures than we saw during the Great Polar Vortex Panic of 2014. If that isn't bad enough, the east could see a couple of disruptive winter storms next week.

Dennis Mersereau · 02/05/15 05:05PM

Models are showing yet another multi-day winter storm in the Northeast this weekend. Accumulations could reach double-digits by Monday night, and that might not even be the worst thing to happen next week. We could see "Dennis Quaid hiking up I-95 to save Jake Gyllenhaal" levels of cold around Valentine's Day. Isn't winter fun?

This beast of a nor'easter looks incredible on infrared satellite imagery this evening, and the storm is only in its infancy. Conditions will rapidly deteriorate in locations that haven't gone down hill already. Locations caught under the deformation zone (heaviest persistent bands) will see two or more feet. Stay safe and enjoy.

Dennis Mersereau · 01/25/15 12:59PM

All signs point to a significant blizzard in the Northeast on Monday night and Tuesday, with major cities like New York and Boston probably measuring snow in feet by the time the storm clears out. If the forecast pans out, this will be one of the most significant winter storms we've seen in quite a few years.

Dennis Mersereau · 01/24/15 03:12PM

Rumors are running rampant about a potential blizzard in the Northeast on Tuesday. The last two runs of the European model produce a crippling snowfall across heavily populated areas. I'm going to wait until tomorrow afternoon's model runs before I dive in and start sounding the alarm, but area residents should get ready just in case.

A snow and ice storm will disrupt travel in the Mid-Atlantic and Northeast tonight and tomorrow, but it's nothing abnormal for this time of the year.
