Dayton is starting Tuesday, November 3, near 57 degrees under mostly clear skies, but the calm opening will not last all week. Sunshine will push temperatures into the lower to middle 70s this afternoon, with south winds between 8 and 13 mph before a wetter, stormier turn arrives overnight.

Warm Tuesday Gives Way To Overnight Storm Chances

Tuesday should stay sunny, making it the week’s easiest window for errands, outdoor work and evening plans. Temperatures will remain mild after sunset, with a low near 61 and increasing clouds.

Showers and thunderstorms are expected to develop later tonight and spread through Wednesday morning. The National Weather Service forecasts rain continuing into Wednesday morning.

The sharper midweek turn is a meaningful update from the earlier Dayton forecast, which called for widespread rain Wednesday but a lower thunderstorm threat. The latest outlook now points to a wetter and more active day across the Miami Valley.

Wednesday Brings Heavy Rain And Gusty Winds

Wednesday, November 4, is expected to be cloudy with showers and thunderstorms, a high near 70 and a 100% chance of precipitation. New rainfall could total half an inch to 1 inch.

Wet roads and reduced visibility could affect travel during the morning and afternoon. The latest forecast lists no watches, warnings or advisories, but anyone outside should take lightning, heavy downpours and sudden wind gusts seriously.

Cooler, Quieter Weather Returns Late Week

Showers may continue into Wednesday night before tapering off. Thursday, November 5, could bring a few early showers, followed by partly cloudy skies and a high in the middle 60s.

Friday brings a slight chance of rain and a high around 63. Weekend temperatures settle closer to seasonal levels, with highs around 59 and overnight lows falling into the upper 30s.
