- 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.
