This hot and humid weather has been draining on everyone. Outdoor activities have been unpleasant for all. On Thursday we finally was able to break the cap in the atmosphere. A line of severe storms formed along the Blue Ridge and moved off into the Piedmont and into South Carolina.

Some of Thursday’s storms reached nearly 60,000 ft tall and with that came the danger of damaging winds and large hail.

High pressure in the upper levels of the atmosphere has shifted west of the Mississippi River as of Thursday night. This places Western North Carolina back in northwest flow. Notice the thunderstorm complexes across the Plains and Midwest? Those features may work to serve as a trigger for storms on Friday.

Tomorrow’s forecast update is the same as in recent days…high instability and a lowering cap in the atmosphere waiting on a trigger to initiate convective activity…

CAPE (thunderstorm fuel) will again be abundant by early afternoon.
