After our area was able to escape strong to severe thunderstorms on Thursday, many expected Friday to be cooler and more refreshing. You were wrong. Mid level temperatures remain hot — even behind the wind shift boundary that was able to touch off some severe thunderstorms in Pennsylvania on Thursday. As it turns out, mid level capping and dry air in those levels of the atmosphere was able to suppress any thunderstorm development in our area.
Friday will feature conditions quite similar to Thursday. Temperatures will rise into the upper 80’s and lower 90’s away from the area beaches. Humidity values, though lower than Thursday, will still make the air feel somewhat uncomfortable. The air quality will also remain poor. Heat Advisories are in effect to the south and west of New York City, nearer to the Philadelphia metropolitan area.
Thunderstorms, some strong and severe, are again possible in the Northeast US on Friday. This time, they’ll be relegated to areas north and west of New York City. A surface low pressure system over Southeast Canada and an associated cold front will aid in the development of these storms, which are expected to move into Upstate New York and parts of Pennsylvania on Friday afternoon.
For us, only an isolated to widely scattered storm is expected, with the best chance of that being in the lower Hudson Valley. In terms of temperatures? Friday and Saturday will both remain hot and humid, with highs in the upper 80’s to lower 90’s. Beach days, at that. If you can get there!
