MADISON, Wis. (WMTV) - Happy Saturday! Watch out for areas of patchy thick fog out the door Saturday morning. The fog could reduce your visibility to less than a mile in spots. Any threat of fog should be gone by 8 a.m. Saturday morning is a little cooler with temperature in the mid to upper 50s across much the area.

Saturday afternoon will be hazy, mostly sunny and warm. Highs on Saturday will be on either side of 80 degrees, which is seasonable for this time of year. You’ll feel more humidity throughout the day as the dew point temperature climbs into the lower to mid 60s Saturday afternoon.

A cold front will drop south across the area Saturday evening. Scattered rain showers and storms will develop along the front around 8 p.m. The rain and storm activity will move from north to south across the area. Even though threat will likely remain low, a strong to severe storm capable of producing strong wind gusts and hail cannot be ruled out. Much of southern Wisconsin is under a MARGINAL threat of severe weather. This is the lowest threat level. Widespread or significant severe weather is not expected. The storm threat should be over by midnight.

A plume of smoke will also follow the front. This plume of smoke has prompted an AIR QUALITY ALERT, which is in effect until 12 p.m. Sunday. The smoke could cause the air quality to drop to unhealthy levels for sensitive groups: children, elderly and people with heart and lung conditions.
