Most of the scattered rain has moved east of the region this week but at least minor rain chances will continue for the coming days with an increase in clouds.

As long as the humid south/southeast winds continue a limited chance for rain will be in the forecast for several days.

The best focus and forcing for rain still looks to be Monday of the upcoming week.

Because of the southeast wind, we’ll have a steady flow of humidity in the atmosphere. This will cause mostly cloudy skies across the area with at least a minimal possibility of rain for Friday, Saturday, and Sunday. Any shower that develops will be brief until Monday arrives.
