LOWELL -- Heavy fog is causing a slow Monday morning commute across the area as rain and temperatures in the 50s quickly melt snow that fell last week.
The National Weather Service issued a dense fog advisory early Monday morning through 10 a.m. for all of southern New England. Visibility was predicted to be a quarter-mile or less in spots.
Drivers were advised to drive more slowly, as objects ahead don't become visible until in close range.
Showers with isolated thunderstorms are predicted for later in the day, with temperatures falling to around 40 and wind gusts of over 20 miles per hour, the National Weather Service said. Temperatures are expected to fall to the teens tonight.
Far colder temperatures are expected for Tuesday, with highs of only about 15 for the Lowell area.
