CHARLESTON, W.Va. – Drivers across West Virginia may face thick patchy fog before sunrise today, especially along I-64 near Charleston. Reduced visibility could make morning travel risky, and motorists are urged to slow down and use headlights.

According to the National Weather Service in Charleston, conditions will clear into the afternoon with highs reaching near 79. Sunday looks warmer, with temperatures climbing to 81 before Labor Day brings another bright and dry afternoon. Families planning outdoor celebrations should expect plenty of sunshine with highs in the low 80s.

The pattern shifts Tuesday as cooler air begins pushing into the region. Skies will remain partly sunny, but showers become possible late Tuesday into Wednesday. A stronger push of September cool air will drop highs to the mid-70s by midweek, while overnight lows dip into the upper 50s. That cooler pattern will deepen later in the week, with widespread rain and thunderstorms possible Thursday.

This early taste of fall will impact daily routines, especially morning commuters and outdoor workers. Residents should prepare for slick roads in foggy morning hours and keep rain gear handy midweek. For those traveling after Labor Day, allow extra time on Charleston-area roads as changing conditions may slow traffic.

The weather service advises staying updated for potential advisories, especially with increased rain chances Wednesday into Thursday. While Labor Day looks safe for outdoor events, the shift toward cool and unsettled weather signals a different start to September.
