Your Commute: River Valley Fog Through 9 am

This Week's Weather Forecast

River valley fog will be around through the morning commute. Visibilities can change abruptly over short distances, with local pockets of 1/4 mile dense fog possible.

Today will have the last summer feel for a while as colder air moves in Wednesday. Some shower and thunderstorm chances this afternoon give way to a 60-70 percent chance of rain overnight. Then, temperatures will tumble through mid-week with high temperatures in the 50s and 60s into the weekend.
