Forecast: Sunny, high near 46

The National Weather Service is calling for Thursday to be sunny in the Baltimore area, with a high near 46 and west winds around 9 miles per hour.

The weather service is warning drivers to be cautious for ice spots when traveling on secondary roads, bridges, overpasses and other untreated surfaces. Temperatures dropped into the 20s overnight across northern and central Maryland and may have caused wet surfaces from Wednesday's snowfall to freeze over.

A small craft advisory is in effect until midday Thursday for the tidal Potomac River and the Maryland Chesapeake Bay.

Thursday night is expected to be mostly clear, with a low around 34 and west winds around 6 miles per hour.

Friday is expected to be sunny, with a high near 47 and west winds between 3 and 9 miles per hour.

Friday night is expected to be cloudy, with a low around 35 and south winds between 5 and 10 miles per hour. There is a 20 percent chance of snow showers after 1 a.m.
