Sunday's Scattering of Storms

With a weak disturbance working east and then southeast through the Mid Atlantic we will have a chance for some showers and thunderstorms later on Saturday night, continuing into Sunday around town.   The disturbance is not very strong and dynamics with it are not that impressive but any time there is a disturbance around in summer thunderstorm chances exist.  

If the NAM is to be believed on precipitation, the best chances of thunderstorms will be on Sunday across the western and southern parts of the region.   The GFS is a bit faster, with the lion's share of scattered storms on  Saturday night, again with the best chances to the west through south of Philadelphia as these storms (or showers) scoot along to the southeast.   The GFS suggests some pop up shower/storm activity on Sunday but it's widely scattered, if not isolated in nature.

Sunday shouldn't be a washout but it's possible, especially west or south, some spots get some thunderstorms from this weak disturbance as it moves through.
