BALTIMORE — Summer-like heat is building across the Mid-Atlantic, and Baltimore could break a daily record high on Wednesday, October 14. On Tuesday afternoon, BWI Marshall Airport hit 83 degrees. Wednesday’s forecast high of 87 degrees would beat the record of 86 degrees set on October 14, 1975. Across the eastern United States, 58 potential records could be tied or broken.

A large ridge of high pressure centered over the Deep South is driving the unusual warmth. The upper-level high is spreading warm air across the eastern and southern United States.
The ridge stretches from Texas and Louisiana north to the Ohio Valley and east to the Mid-Atlantic coast. Record highs are possible in cities including Nashville, Huntsville, Atlanta, Montgomery, and Jackson.
