High level of heat and humidity continues

 Surface chart

We have a mesoscale convective vortex; all of this means a well-organized cluster of storms. This is bowing and heading east. This is associated with the cold front over the Midwest.

For us in the Northeast, we’re dealing with the trough Satellite is showing quite a bit of clouds over the region. These clouds are going to lessen, the more sunshine we see today the greater the risk for severe weather. 

Today is going to be another hot and humid day, with near record to record temperatures for some of us. Temperatures will be in the mid 80’s well into the 90’s. This will make for heat indexes in the mid-90’s into the triple digits This uncomfortable heat, means everyone must stay hydrated and if you’re going to be working outside you will need to take breaks. Also keep an eye on kids, the elderly, and your animals. heat advisories are up for parts of the region.

Scattered rain showers and thunderstorms will be most prevalent during the afternoon and evening. Some of these storms will become strong to severe.  The storms will be capable of locally damaging wind and hail. Storms would be capable of gusts of over 60 miles per hour; this could lead to downed trees, branches and power lines. With the high humidity torrential rain leading to the chance for isolated flooding and frequent lightning will also be an issue. Remember lightning is one of nature's biggest killers, so keep that in mind when storms are approaching. The risk for a tornado or two is also on the table. The Tri-State area is at the most risk for these possible tornadoes.

The Storm Prediction Center has a Slight Risk for severe storms across southeast New York State and eastern Long Island, western Connecticut, eastern and southern Pennsylvania, Maryland, Delaware, and New Jersey. With a Marginal Risk across western, Massachusetts, much of the rest of Connecticut, southern tier of New York State, and northern and northwest Pennsylvania.

Friday will be another very steamy day and will likely be the hottest day of this current event. But we will have an approaching cold front bringing downpours and thunderstorms. Friday will see a better chance for widespread severe storms across the region. The SPC has the whole area under a Slight Risk for severe weather as of right now over the Eastern half of New York State, a large part of New England and Pennsylvania as well as Maryland, Delaware, and New Jersey.

The Weekend

 Behind the cold front, it will be a little less hot or humid for the weekend, but it will still be quite warm with a touch lower amount of humidity.  High pressure will be building in allowing skies to become partly sunny on Saturday, and it looks to be mostly a dry day On Sunday, expect conditions.  Another cold front will approach from the Great Lakes Sunday afternoon and Sunday night, bringing back the chance for showers and thunderstorms later Sunday and Monday as it slides through.
