A ridge present across the central United States continues to dominate the weather for the country. Several pockets of higher vorticity located on the northern portion of this ridge will affect the Eastern United States. Mesoscale thunderstorm events will be associated with these which could lead to some severe weather especially in the Ohio Valley. The ridge will become less amplified going into the weekend will decrease the chance for any major thunderstorm activity and decrease any significant any positive vorticity advection over the Great Lakes and East Coast.
