Chilly July Temperatures Set Record Lows At BWI

BALTIMORE (WJZ) -- For a fifth time this month, the mercury at BWI Marshall Airport hits a record low.

Temperatures fell to 55 degrees Wednesday morning according to the National Weather Service, breaking the previous record of 56 set in 1997.

Meteorologist Chelsea Ingram reports the pattern of the jet stream has been bringing us unusually cool weather this month.

As the jet stream dips well to our south, it pulls down cooler Canadian air along with it.

When temperatures fell to 57 degrees last Friday, a record low was set--beating the old record low of 59 degrees set in 2008. The same temperature set a record low on July 18, beating the old record of 58 degrees set in 1976.

And Tuesday's low of 59 degrees ties with a record set in 1978.

During the Fourth of July weekend, Saturday's record low of 55 degrees tied with that of 1979.
