Freezing temperatures were warned for much of Maryland on Saturday morning, but it didn't get quite that cold in areas within several miles of the Chesapeake Bay. Further from the water, though, temperatures were much colder.

At BWI Marshall Airport, Saturday's low was 35 degrees (Anne Arundel County wasn't included in a freeze warning area the National Weather Service's Baltimore/Washington office established). BWI is the official point of record for Baltimore. Record lows this time of year are in the 20s.

Downtown at the Maryland Science Center, it was much warmer -- a low of 45 degrees, keeping things relatively comfortable for runners readying for the start of the Baltimore Running Festival. The U.S. Naval Academy in Annapolis bottomed out at 46 degrees.

But further inland, there was a chill, to be sure. Here is a sampling of low temperatures around Maryland, Washington and Virginia:

  • Hagerstown Regional Airport: 32 degrees
  • Dulles International Airport: 30 degrees
  • Reisterstown weather co-op: 32 degrees
  • Carroll County Regional Airport: 30 degrees
  • Frederick Municipal Airport: 28 degrees
  • Gaithersburg Airport: 30 degrees 

The low in Frederick tied for the coldest measurement around the Baltimore/Washington weather service forecast area, which includes northern Virginia to the Shenandoah and most of Maryland, but for extreme western and eastern parts.

Another taste of chilly fall weather isn't in the forecast anytime soon. Highs this week are expected in the upper 60s and lower 70s, with lows in the mid-40s to lower 50s, slightly above normal for this time of year.
