Cold expected to follow heavy rains, strong winds
Cold to linger through the rest of the week
MADISON, Wis. — A strong storm system will move from the Central Plains Tuesday to Wisconsin Tuesday night, bringing heavy rain and a slight chance of severe thunderstorms followed by a dramatic dip in temperatures.
As the system moves in Tuesday night, it will bring heavy rain producing showers and thunderstorms through the area mainly after midnight through the morning hours of Wednesday. We can expect two to three inches of rainfall in general as the system moves through with locally higher amounts possible, especially if storms continue to move over the same areas in succession.
It will be very windy due to the powerful low as winds will be gusting above 30 miles per hour Tuesday night and Wednesday.
There is a Flash Flood Watch for all of southern Wisconsin for Tuesday night and Wednesday morning due to the threat of heavy rain.
The rain will end quickly as a cold front passes through the area. Behind the front, much colder air will spread across southern Wisconsin, causing temperatures to fall Wednesday afternoon and leading to very unseasonably cool temperatures for the rest of the week.
Highs on Thursday will be near 60 and by Friday they will only be in the mid 50s as another chance of showers moves through. Overnight lows will be near 40. Patchy frost will be possible northwest of Dane County Thursday and Friday nights.
Temperatures will slowly warm back into the mid 60s over the weekend as high pressure returns.
