Still Hot, but cooler weather is around the corner!

Today we’re all dealing with summer like heat along with some humidity.  Most of us will approach or set new record high temperatures. With the heat and humidity, it's going to feel like mid-summer.

 Look at the current surface chart and radar. 

We can see the warm front has pushed into Canada and northern Maine. The southern flow is driving in plenty of heat with most of y’all seeing temperatures in the upper 80’s into the upper 90’s. The higher dew points will make it feel warmer than that.  We can also see that strong cold front out west that is approaching our region. As this gets closer and starts to run into all this heat, out ahead of it we will see scattered showers and thunderstorms develop, some of these will be strong to severe. Here is a look at today’s convective outlook for today.

This afternoon severe thunderstorms are likely to develop over northwest Pennsylvania, western and northern New York State. The biggest threat will be strong damaging winds and large hail. But with the humidity, frequent lightning and heavy downpours are also going to be a concern. The tornado risk is low, but a couple of isolated tornadoes are possible. The severe threat is going to extend into tonight as these move west to east. Way out ahead of the front there is a chance for some isolated showers and thunderstorms popping up this afternoon – a couple of these could be strong to severe.

We do have a few shortwave troughs that could be the focus for a few thunderstorms, this will be especially true for eastern Pennsylvania into Maryland Delaware New Jersey as well as New York City and Long Island. 

Wednesday 

As the cold front approaches, the Hudson Valley and eastern Pennsylvania, a few showers and maybe a few thunderstorms will be late morning and into the early afternoon. The as the front is dropping south and east into the lower Hudson Valley, southern New England, southwest Pennsylvania and the northern Middle Atlantic later Wednesday afternoon into the evening, scattered showers and thunderstorms are likely to flare up again with the potential of damaging wind gusts and large hail. 

End of the week and through the weekend.

 Behind the cold front, temperatures will turn noticeably cooler with the front pushing away Thursday is looking to be a mostly dry day with a mix of clouds and sun. The High pressure will continue into Friday. But on Friday we will be watching a frontal boundary to the south, try and push north, bringing a chance for rain showers into Maryland, Delaware, southern New Jersey and southern Pennsylvania. We also going to have a Canadian High Pressure centered up over the Canadian Maritimes and low pressure in the Gulf of Maine.  Between the high pressure and the slowly advancing frontal boundary, it’s going to keep us very cool and unsettled through the Memorial Day Weekend. For Memorial Day Monday, the boundary should be pushing north and west most of the region could see lingering showers, but up over New England scattered rain showers are likely. 

That’s it
