It gets worse before it gets better!

 Well we made it to friday.

The end is in sight, as the dome starts to ever so slowly begin to break down.

 

Looking at the temperature and dew point charts, we can see the high heat and humidity are still over the region, this means the Heat Advisories and Extreme Heat Warnings are still in place effect, but northern New England is seeing a little relief. The Advisories and warnings look to be in place across northern New York State into this evening.  But for the areas south the Extreme Heat Warning will continue until Saturday.

 

Looking at the surface chart, we can see that weak cold front approaching out of Canada. This is going to be dropping south through the region this 4^th of July weekend.  

Today will also feature a chance for scattered showers and storms, and some could be strong to severe, The SPC has the region under a slight Risk of severe weather today, with damaging winds, hail, frequent lightning, and heavy downpours. The best chance for storms will be midafternoon through this evening across New York State into New England, so most of the fire work displays should be ok. But the timing of all this could place some of the firework displays across parts of Pennsylvania as the chance for some storms will extend into tonight and the overnight.

Tomorrow that cold front will continue to slow drop into the region. Kicking off showers and storms, the SPC has the Southern Tier of New York State into southern New England under a Marginal Risk of severe weather, with a Slight Risk area across most of Pennsylvania and the northern Middle Atlantic, with damaging winds, hail and heavy downpours being the biggest risk in any storms that turn severe. Timing for any storms would be similar to today.

The severe risk is even farther south on Sunday, with a Marginal Risk over much of Pennsylvania, much of New Jersey into Long Island. The Slight Risk is over much of southern Pennsylvania, Southern New Jersey as well as Maryland and Delaware.  

 As the heat dome continues to retrograde back to the west, we will see this gradual reduction in the hot conditions across the region. As the high-pressure ridge setup across the west.  That cold front will continue to drop south Sunday night and Monday, so it will be cooler and less humid north of the frontal boundary. But southern Pennsylvania and the Middle Atlantic will still be dealing with some heat and humidity. Those areas will also see increased risk for showers and storms. Some of this could linger into Tuesday morning before things quiet down. Tuesday and Wednesday should be much cooler than they have been, with temperatures returning to somewhat seasonal.

Have a great Friday.
