Turning Active Again Soon

The quite weather continues and we are not at mid-week. There just has not been much to discuss or write about lately. This should change this weekend. Basically, we are in an atmospheric traffic jam. High pressure is holding firm across our region while a strong low pressure system exists out over the Atlantic Ocean. Meanwhile, a stationary front has been nearly stationary to our southwest and that front has been responsible for significant severe weather from Ohio down through South Carolina.

The ridge that has been bouncing the thunderstorms off the invisible barrier will begin to breakdown and shift eastward, doing so very slowly. This will allow a weak front to slowly move eastward this weekend. As it makes a closer approach, thunderstorm and rain shower chances will increase. Since everything is jammed, it will also take several days to push the unsettled weather out of here.

Saturday through Tuesday look to be the days that are most unsettled at this point. Daytime heating will lead to the best shower and thunderstorm chances each day. Some days could feature some strong to severe thunderstorms and thunderstorms with locally heavy rain. Slow moving storms may pose an increased risk for localized flooding. A good Atlantic and Gulf moisture flow would only enhance the heavy rainfall threat.
