Current upper air pattern has the base of the system that brought showers and thunderstorms across eastern Pennsylvania and New York Friday into the Atlantic Ocean. High pressure is over the Ohio Valley with a stalled front across the southeast stretching back into the Plains. A closer look at our region has the base of the trough moving into the Atlantic, but it will be cold enough aloft to allow for more instability, showers and a thunderstorm to form Saturday afternoon.
There is an inverted trough still hanging around through Connecticut, which is allowing for the showers to pivot round that surface low pulling away into the Atlantic. Once the sun comes out, the cumulus clouds will build Saturday afternoon. A few showers and thunderstorms will once again form. Temperatures will run around average for this time of the year with middle 70s. Saturday night, the high pressure will build, allowing for skies to clear again overnight.
