An area of low pressure moving into the eastern United States could set-off some severe thunderstorms in the northeast and southeast this afternoon and evening.
The latest water vapor loop from the GOES-East weather satellite shows a progressive shortwave trough moving into New York state. Lift ahead of this system will likely result in a fast-moving line of low-topped showers and a few thunderstorms this afternoon and evening over parts of eastern NY/PA. Strong wind aloft and steep low-level lapse rates will promote the risk of gusty and occasionally damaging wind gusts this afternoon. While severe storms will create large hail and isolated tornadoes from time to time, the environment isn’t very favorable for either today.
In the southeast, a slow-moving upper trough is moving eastward across Alabama today with the associated southwesterly mid-level winds extending from the northern Gulf of Mexico into Georgia and South Carolina. Visible satellite imagery from GOES-East shows considerable heating is occurring from central Georgia into the northern Florida peninsula, where conditions are ripe for severe storm development. Rather cold temperatures aloft may also set the stage for hail here, some of which could be large. The area of greatest concern extends from southeast Georgia down to the east coast of the Florida peninsula.
