The region turns humid late in the day on Friday and a shower or thunderstorm are possible north and west. Widespread showers and thunderstorms materialize on Saturday as an expansive cold front crosses the region.

Widespread severe weather is not expected at this time, however, and isolated stronger storms can form prompting damaging wind gusts.
