Monday Update

A Flash Flood Watch has been issued for Green and Rock counties in southern Wisconsin, through 9am Tuesday. This area has already been battered by several rounds of heavy rain late last week, and with the potential for more heavy rain this afternoon and evening some localized flooding  will be possible.

Heavy rain is currently falling near Amboy and through portions of Carroll and Jo Daviess counties, and will continue to lift northward. there hasn't been much lightning detected, but you'll want to watch for ponding on some area roads. This first wave of rain will move out of the area this afternoon, but behind it we will need to keep an eye on any potential clearing of the cloud cover. If we get the sun to mix out the clouds, it could allow for enough destabilization to occur which would lead to more instability. If we get enough instability then this could prompt a few stronger storms for portions of the Stateline area this afternoon. If the warm front lifts far enough north, then it is also possible for a spin up weak tornado or two. The atmospheric conditions however aren't conducive for any long lived strong tornadoes. The threat for heavy rain will continue into the afternoon and evening, with many receiving .25" to .75" inches of rain, though some localized higher totals are possible.

The coverage of showers and storms will decrease tonight into Tuesday, though can't rule out a few showers and storms Tuesday afternoon.
