Summer storms brought another round of heavy rain, flooding and damaging winds to parts of the eastern U.S. on Friday.
An 89 MPH wind gust was reported in Cumberland County, New Jersey, on Friday night, and damaging winds downed some trees in Delaware as well. Over 4 inches of rain also fell in Winterthur, Delaware.
These summer storms come just days after Isaias went through the region, bringing damaging winds and torrential rainfall. A city like Allentown, Pennsylvania, has seen more than 7 inches of rain so far in August, which is 6 inches above its month to date average.
The good news is the summer storms are calming down in the eastern U.S. The threat for additional flash flooding is quite slim now, with only isolated storms possible.
A couple of systems will combine to cause summer thunderstorms to develop later Saturday and into early Sunday. The threat Saturday will be from Nebraska to Minnesota, and then will move into central Minnesota and Wisconsin by Sunday.
The main threat will be damaging winds and large hail. Any slow-moving thunderstorm could produce flash flooding as well.
Meanwhile, in the south-central U.S., some of the summer heat will try to build this weekend. The heat index in parts of Oklahoma and Kansas is expected to be over 100 degrees. Therefore in some spots, a heat advisory has been issued.
After Isaias, the Tropics are briefly much quieter. There is a system that is being monitored for development in the Atlantic, which only has a 10% chance of developing further. It is almost guaranteed that the Atlantic will fire up again with activity as we head further into August.
