While a widespread severe weather outbreak is not expected in the Northeast, storms capable of causing disruptions and damage at the local level are likely Tuesday afternoon and evening.
People spending time outdoors or on the road should keep an eye out for rapidly changing weather conditions.
A mosaic of showers and thunderstorms will form during the midday and afternoon hours over the Northeast. A few of the storms will become severe, capable of producing frequent lightning strikes, moderate hail, damaging wind gusts and flash flooding.
Some neighborhoods will be hit with downed trees and power outages as well as street flooding and travel delays.
The greatest risk for these storms extends across Ohio, western and northern Pennsylvania, northern New Jersey, much of New York state, much of New England, southern Ontario and southwestern Quebec.
Cities that could be hit by a severe thunderstorm include Cleveland, Columbus, Pittsburgh, Scranton, Albany, Buffalo, New York City, Hartford, Boston, Burlington, Vt., Concord, N.H., Portland and Augusta, Maine, London and Toronto, Ontario, and Montreal, Quebec.
Storms will also fire farther south in the mid-Atlantic and Appalachians. While these are likely to much more widely separated, they can still briefly become severe.
Remember, if you can hear thunder, you are at risk for being struck by lightning. Move indoors as storms approach. Picnic pavilions and golf carts do not offer adequate protection from lightning.
In some cases the storms will be small in size, developing and dissipating rather quickly. In other cases the storms can organize into a squall line, move along for a few hours and cover a hundred miles.
Most of the storms will diminish soon after dark. However, in a couple of cases a complex of storms rolling in from the Midwest can survive well into the night.
Additional thunderstorms will fire through the remainder of the week. Thursday is the most likely day where an organized, broad area of severe weather occurs on the I-95 corridor from Washington, D.C., to New York City and Boston as the main batch of energy from the Midwest reaches the East Coast.
The frequency of thunderstorms, and especially downpours, will increase significantly during the coming weekend into next week and will raise concerns for flooding.
Snow will move in Sunday afternoon around Chicago sparking slippery conditions and travel delays.
A magnitude 4.5 earthquake shook the ground near Jones, Okla., Saturday afternoon.
It has rained every day so far this month, except December 1 around Atlanta. That trend will continue for a few more days.
While heavy snow and ice are not expected to fall over much of the Midwest Sunday into Monday, some slippery roads and travel disruptions are likely.
Fresh cold is setting the stage for the weekend to end on an icy note in Pittsburgh.
A storm coming Sunday night has the potential to bring wintry travel problems to Boston and New England.
