Touch Of Grey

Folks across the mountain state got a well deserved break from grey skies and wet weather Thursday. Conditions stay warm in the upper 70s today under a mostly sunny sky. We’ll see increasing clouds this afternoon as a deep upper level disturbance meanders across the Ohio valley. Rain showers and a few thunderstorms will develop tonight, continuing through Saturday. As with any system, the timing of the front will become vital in determining just how much rainfall will be realized this weekend. The generally slow track of the trough means that showers will be slow to move eastward. As a result, all points west will pick up more rain sooner than the eastern portions of our state. Here, we can expect to see less than half an inch of rain to fall late tonight/Saturday. Abundant cloud cover should keeps temperatures in check on Saturday. This will also suppress the development of instability in the upper atmosphere. So any thunderstorms would be very isolated this weekend. High pressure will gradually muscle any lingering moisture further east on Sunday. So look forward to abundant sunshine as much warmer temperatures next week!
