- Cool and comfortable, highs in the low 70s
- Upper level low moving through may trigger afternoon storms
- Chance for flooding rains underneath storms
Temperature Forecast for today is pretty nice for July.
Surface Low just off NJ coast, this is part of the system that brought rains yesterday
24 Hour temp change
Chance of storms this afternoon. Better chance for some small hail if we get some sunshine to destabilize the atmosphere.
GFS dynamic tropopause shows the upper level low well as. We are under an area of fast upper level winds and tropopause temperatures indicative of polar/cold air. This cold upper level air will help destabilize the atmosphere if we get warm sun.
Hi-resolution NAM shows some showers/thunderstorms early afternoon
Not expecting widespread severe weather but hail or flooding is possible under these storms. They won’t be moving very fast, and some may pop up right behind the other.
Enjoy the holiday weekend!
