The next cold front is moving eastward through the Great Lakes and it is setting up Eastern Pennsylvania to Southern New England for late day and nighttime thunderstorms along with the potential for some of those thunderstorms to be severe. The Storm Prediction Center has expanded the slight risk zone to extend from Eastern Kentucky to New York State and the Hudson Valley south to New York City and Western Long Island. Marginal risk for severe weather extends into Southeastern New England.

Humidity levels are shooting up today as a warm front goes by to the north. Dew points will be rising to the upper 60s to around 70. Temperatures will be shooting up as well as highs reach the low and middle 90s in many areas. Look for sunshine into the afternoon before the cold front begins to get close. Right it appears that other than perhaps some renegade thunderstorms that pop up, the main area likely comes later in the evening and tonight.

Weather models seem to be in very good agreement as to how these storms play which is rather unusual. When it comes to convection you usually see different solutions and ultimately it becomes a game of watching the radar to see how things all play out. It appears that a lead squall moves across Eastern Pennsylvania later in the evening. Storms are forecast to reach the New Jersey coast and Western Long Island around 9 or 10 pm. The biggest risk from these thunderstorms appears to be straight line wind and gusts of 50 to 60 mph are possible as the lead squall line moves through. There will be a second band of downpours and perhaps a thunderstorm or two behind the first squall line and that will move offshore during the early morning hours Thursday between 2 and 6am.
