Well weather.com is calling for the following as of right now...
Sunny - High 72 - Low 59 - 20% chance of precip
Scattered T-Storms - High 78 - Low 57 - 40% chance of precip
Which suggests the following:
Chance of at least on rain free day: 92%
Chance of a rain free weekend: 48%
Looks like a possibly good climbing weekend, unfortunately weather.com is also predicting at least a 30% chance of rain for every day between now and Friday with a 70% chance for Thursday. This isn't good for the area; which has received far too much rain in the last week, resulting in the flooding shown below. What you're seeing in those videos is the collapse of Lake Delton a few miles from Baraboo.
