There hasn't been much of a change in the overall weather pattern.
High pressure remains along the East Coast.
This is allowing for a summer-like weather pattern to continue. The above normal temperatures will last through Saturday. A cold front over the middle of the nation into the Great Lakes will sag southward into the Tri-Cities area on Saturday. This front will have the potential to spawn a few scattered showers on Saturday. Unfortunately, it will likely not deliver the kind of rain our dry ground could use.
