A severe thunderstorm watch has been issued until 7 PM for the following areas. We're still expecting scattered thunderstorms later this afternoon into perhaps into early this evening. We're not confident in how widespread thunderstorms will be this afternoon, some areas may well get missed by storms, but conditions are favorable for thunderstorms to be capable of torrential rainfall and locally damaging downburst winds where storms do develop/occur.
