Today will be drier compared to the last few days. However, Lake Superior will help to limit RH dropping below 40 percent. The lake breeze is expected to move out from Lake Superior 11-Noon, which will cause winds to quickly switch from the northwest to the southeast. However, winds will remain less than 10 mph during this switch since a high pressure will be in place. Thursday will be more windy out of the east to northeast, but the lake will once again keep RH from getting below 40 percent. .TODAY... Sky/weather.........Mostly sunny (30-40 percent).
