Snowfall blanketed much of southern Maine on Monday evening, causing a few minor crashes during rush hour and slowing down traffic.

The Maine Turnpike Authority lowered the speed limit to 45 miles per hour between Kittery and Augusta, hoping to stave off more crashes.

The forecast called for between 2-4 inches of snow throughout southern Maine, with precipitation tapering off around midnight, according to the National Weather Service.

The weather is supposed to warm up beginning Tuesday, with temperatures topping out at 38 degrees in Portland. On Wednesday, temperatures could exceed 50 degrees in much of southern and central Maine, the weather service said.
