Knoxville is starting Sunday, October 4, with fog, mist and near-calm winds as temperatures sit around 68 degrees. Showers and thunderstorms are expected to move through the area today, making for a damp finish to the weekend before a much sunnier stretch arrives.

Rain Chances Peak Late Morning Into Early Afternoon

The National Weather Service forecasts a cloudy day with a high near 78 and a 70% chance of showers and thunderstorms. The wettest window should run from late morning into early afternoon, although a few showers could linger into the evening, according to the National Weather Service.

The NWS forecasts just over a half-inch of rain in the southern valley, with potentially higher amounts where rain trains. Recent heavy rain has left some ground saturated, so drivers should be alert for ponding and never attempt to cross a flooded roadway.

Sunny Skies Return Monday

Sunday night turns cloudy with a low around 60 and only a slight chance of rain before 8 p.m. Monday brings a sharp reset: sunny skies, a high near 79 and northeast winds of 5 to 10 mph.

The updated outlook is less soggy than Saturday's Hoodline forecast, which called for a much higher Sunday rain chance. Dry weather now appears likely through most of the week, with sunny highs near 80 Tuesday, 81 Wednesday and 82 Thursday.

Dry Weather Continues Through Friday

Dry weather continues through Friday, with late-week warming. Precipitation chances may return next weekend.
