...Heavy Rainfall With Additional Flooding Possible Into Early
This Weekend...

An active weather pattern will occur across southern Wisconsin
into early this weekend. Several periods of thunderstorms
producing heavy rainfall are likely. The best chances will be
mainly this evening, later Wednesday night into early Thursday
morning, and again Friday into Saturday. Otherwise, chances for
thunderstorms will linger across the area.

Fueled by very humid air just to the south, the rainfall rates
with these systems will be high. Thus, the risk for flooding will
be on the increase through the week. Should these thunderstorms
track over the same location with heavy rain, flooding could be
the result. Far southeast Wisconsin will be most vulnerable,
already hit with earlier flooding. Urban areas will also be more
at risk for flooding.

As this week continues, there should be better confidence on
timing with any rounds of thunderstorms, as well as with rainfall
amounts. Keep up with the latest forecasts, as Flash Flood
Watches and Warnings may be needed later this week.
