The forecast has changed a little bit over night from the previous update. It looks as if some scattered thunderstorms and showers will start up late tonight and continue to the morning hours of Sunday. For those going on the river, make sure you come prepared for rain and stormy conditions. Read up on river and storm safety under the trip planning tab at the top of the page. It looks as if localized heavy rain will be the main factor in these storms so our section of the river may or may not be hit. Make sure you pull boats high onto the sandbars and tie them up or weigh them down so they don’t get lost in stormy weather.
Here is a more in depth look at the forecast for our area.
As the overnight hours go on into Sunday morning, thunderstorms may tend to train over portions of southern Wisconsin. I do think that southwestern to south central Wisconsin may have the best potential to see this training activity, which would enhance rainfall totals there, and may cause some localized urban and small stream flooding. There may be a bit of a lull in activity late Sunday morning into Sunday afternoon before some redevelopment occurs late in the day over southeastern Wisconsin. Then overnight Sunday into Monday, a sfc wave is expected to ride northeast along the sfc front toward Wisconsin, kicking off another round of scattered showers and storms overnight into the first half of Monday. Luckily, this sfc wave will be the kick the slow cold front needs to finally exit and as the front clears Wisconsin to the south and east Monday afternoon, shower and thunderstorm activity should finally end.
