Damp September Finale: Drizzle and Fog Give Way to Cooler Autumn Days in Bennington County

Welcome to the final days of September in southwestern Vermont. As we transition deeper into autumn, the Bennington Valley is experiencing a classic shift in seasonal weather patterns. Currently, our local conditions are quiet but grey, with overcast skies hanging low over Mount Anthony and the surrounding ridges. The temperature is hovering at a mild 58.8 degrees Fahrenheit, accompanied by a very gentle breeze of just 2.9 miles per hour. While there are no active weather alerts or warnings in place for Bennington County, residents and commuters should prepare for a damp, low-visibility start to the week before drier air arrives to close out the month.

Three-Day Local Forecast Breakdown

Monday, September 28: A Damp and Drizzly Start

Our workweek begins with damp conditions across the region. On Monday, expect a high temperature of 61.3 degrees Fahrenheit and a low of 54.8 degrees Fahrenheit. The main weather story for the day is a persistent moderate drizzle, with a high precipitation probability of 82 percent. While we are not expecting a torrential downpour, the system is forecast to bring about 0.154 inches of total rainfall. Winds will remain light, peaking at around 6.9 miles per hour, which means the dampness and low clouds will likely linger throughout the day, keeping the air feeling cool and saturated.

Tuesday, September 29: Morning Fog and Mild Temperatures

As the moisture from Monday’s drizzle settles into the valley, Tuesday will start with widespread fog. This fog could be quite dense in low-lying areas and river valleys, so early morning commuters should plan for extra travel time. The high temperature will rise slightly to a comfortable 63.9 degrees Fahrenheit, while the overnight low will hold steady at 54.6 degrees Fahrenheit. Fortunately, the chance of rain drops significantly to just 7 percent, with no measurable precipitation expected. Winds will pick up slightly, reaching a maximum of 9.9 miles per hour, which should help gradually disperse the fog by the afternoon.

Wednesday, September 30: Overcast and Cooler to Close the Month

We wrap up September on Wednesday with dry but overcast conditions. Temperatures will reach their highest point of the three-day stretch, peaking at 67.5 degrees Fahrenheit during the afternoon. However, once the sun sets, a cooler air mass will settle into the region, dropping the overnight low to a chilly 49.4 degrees Fahrenheit. There is a 0 percent chance of precipitation on Wednesday, and winds will be very light, topping out at 4.7 miles per hour. This cooler overnight drop is a classic reminder that October frost season is just around the corner.

Commuter Impacts and Mountain Travel

The transition from Monday’s moderate drizzle to Tuesday’s fog will create some challenging driving conditions across southwestern Vermont. Commuters traveling along US-7 between Arlington, Shaftsbury, and Bennington should expect wet roadways on Monday and reduced visibility on Tuesday morning.

The impact will be particularly noticeable for those driving the Molly Stark Trail (VT-9) through Woodford. This high-elevation route is notorious for sudden visibility drops, and the combination of Monday’s drizzle and Tuesday’s fog could make mountain driving hazardous. Additionally, drivers utilizing the VT-279 bypass should stay alert for slow-moving traffic and maintain a safe following distance. Remember to turn on your low-beam headlights in both drizzle and fog to ensure you are visible to other motorists.

Outdoor Recreation and Autumn Foliage

For leaf-peepers and outdoor enthusiasts looking to explore the Green Mountain National Forest or hike around Mount Anthony, the early part of the week will require some caution. Monday’s drizzle will make local trails wet, muddy, and potentially slippery. If you are planning a walk around Lake Paran in North Bennington or a hike in Pownal, wearing waterproof footwear and dressing in layers is highly recommended. By Wednesday, the dry weather will offer a much better opportunity for outdoor activities, though the overcast skies will make for a more muted, atmospheric view of the early autumn colors.

The Bottom Line

Keep your umbrella handy on Monday for the moderate drizzle, and allow extra time for your Tuesday morning commute to navigate the local fog. By Wednesday, we can look forward to dry, overcast skies and a high of 67.5 degrees Fahrenheit, followed by a crisp Wednesday night low of 49.4 degrees Fahrenheit that will officially usher us into October.
