Late-Week Severe Threat

Later this week we are looking for severe weather to impact the Northeast. The storm system that will bring a severe outbreak to parts of the Central US will move into the Northeast later this week and bring along the severe threat. In the Northeast, we could see some damaging winds, small hail, and the possibility of a few tornadoes.

We are expecting the severe weather threat to be primarily in central and southern New York, up into parts of northwest Connecticut, western Massachusetts, southern New Hampshire, and southern Vermont. This event for the Northeast will take place Thursday afternoon and linger into Friday evening.

Late this week will have very warm and humid air being pumped into the Northeast and Midwest from the strong Bermuda High which will be a key ingredient in the potential for any severe weather. The lifting mechanism is the cold front that is will be associated with the impending storm system.

The battle between warmer temperatures to the east of the front and the cooler temperatures behind the front creates a convectively unstable environment which is going to contribute to thunderstorm growth along and out ahead of the front.

Another factor that is contributing to the severe weather threat is how much energy will be available.

Thursday Afternoon 5/3 :

Friday Afternoon 5/4:

The energy needed to create severe storms is in the areas mentioned above which gives us confidence for seeing strong storms in those areas.

Above, is the current Storm prediction Center’s forecast for severe weather on Friday. I believe that their forecast is pretty accurate, but I would expect the marginal risk to extend down into the Hudson Valley and move a little bit more south near Syracuse. The hazards do include damaging winds and the potential of a tornado especially Friday afternoon. Make sure you stay here with us at East Coast Weather Authority as we get you prepared for this potential as we get closer
