Slight Risk in Mid atlantic states in USA !


METD WEATHER,
Akshay Deoras
Severe Weather Forecaster

3 TORNADOES ALREADY REPORTED IN NORTH CAROLINA. REPORTS YET TO BE CONFIRMED. MANY MORE TORNADOES POSSIBLE
A classic upper level trough ejecting over the Eastern states of USA having maximum jets of 80kt will bring down some severe weather along with the classic 50kt low level jets centered over Central-Eastern Virginia, North Carolina,Maryland,PA,NYC
Maximum CAPE of 2000J/Kg will build over East coast of North Carolina,Virginia coupled with 200 m2 s2 Helicity at 0-1km level
Severe weather will pop up in Mid atlantic states in the warm moist sector having Surface dewpoints of 70F.

Discrete supercells will form and all of the will be HP since the precipitable water is 2.0"+ in most of the areas. The tri front point will center over North Eastern North Carolina which I guess has the maximum tornado threat
Tornado watches already in effect in many areas. The main risk lies in Eastern North Carolina,Eastern Virginia, Maryland,Washington area

Strong RIP currents and winds will strike coastal areas. AS MENTIONED IN THE PREVIOUS POST, HEAVY RAINS 2-6" AND FLOODING POTENTIALS WILL HAPPEN IN
