BWI hits record low; frigid afternoon could break another mark

Baltimore set a new record low of 19 degrees for Wednesday's date, and a second record was possible in the afternoon as a mass of Arctic air lingers over the eastern United States.

Baltimore-Washington International Thurgood Marshall Airport dropped to 19 degrees in the early morning hours. The record low for Wednesday's date was 20 degrees, set in 1936.

After that, another day of sub-freezing wind chills is forecast. Highs are forecast in the lower to mid 30s, likely below a record for the coldest daily maximum temperature for Wednesday's date, 35 degrees, set in 1880.

The airport reached 31 degrees by noon, with wind chills in the lower 20s.

Winds are forecast to be calmer than they were Tuesday, with 10 mph breezes making it feel like the 20s for most of the day -- instead of the teens like Tuesday. Clouds are forecast to gradually increase throughout the day.

Temperatures in all 50 U.S. states dipped to freezing or below on Tuesday, which marked the coldest November morning nationwide since 1976. Typically, such cold is not seen until late December through February, according to the National Weather Service.

An autumn blizzard dumped five feet of snow -- a year's worth -- in three days on Western New York state, where five people died and residents, some stranded overnight in cars, braced for another pummeling expected later on Wednesday.

Records were also set Wednesday at Dulles International Airport in Northern Virginia, which smashed a record low of 20 degrees when it dropped to 13 degrees, as well as in areas stretching from New York City to the Florida panhandle.

In Baltimore, temperatures are expected to moderate slightly going into Thursday, with overnight lows staying around freezing and highs Thursday in the mid-40s. Winds are expected to pick up again, though, reaching 20 mph gusts.

Lows drop back into the 20s Friday and Saturday mornings, with highs in the mid-30s Friday.

Highs are forecast in the lower 40s Saturday and then, for a big change, near 60 degrees on Sunday with rain likely.
