Mid-Atlantic Discussion: May 22-23

A weakening disturbance will bring enough instability into the area this weekend for afternoon showers and garden-variety boomers as it lifts out of the trough to our west. Severe will be isolated west of the Appalachians, and is not expected along the East Coast at this time. There is only a little dynamic forcing with the Mid-Atlantic airmass, with very weak speed shear and limited moisture. Other than that, sit back and enjoy our seasonal temps as a Death Ridge takes hold of the eastern half of the U.S. Onshore flow will continue through next week, with a subtropical low pressure system possibly making an appearance along the Coast.
