- Mostly Dry Pattern Continues
Area of showers and thunderstorms across Wisconsin will be moving southeast this morning and gradually dissipating as the low level jet weakens. Best chance for rain will be across the southeast zones. Isolated showers persist into the afternoon across the southern half of the forecast area as enough instability develops and low level moisture persists for some updrafts.
Surface high builds south with dry east to northeast flow tonight and upper ridging should hold off any precip until at least the middle of next week when moisture return increases as the high moves east.
