Temperatures Hit Record at Dulles; Tied at BWI, National

At 3 p.m., the heat index at National Airport was at 112 degrees

The severe weather for the D.C. area has passed, dropping temperatures nearly 20 degrees in some areas. It brought some relief to a region that saw record temperatures on Monday.

Storm Team4 said the official temperature at Reagan National Airport hit 100 degrees, tying a record high set in 1930. That record has been matched in other years.

A record high of 100 degrees for this day was set at Dulles International Airport in Chantilly, Virginia, breaking the previous record of 98 degrees in 2010.

Meteorologists said BWI airport in Linthicum, Maryland, tied 2010's record daily high of 100 degrees.

Storm Team4 said 90 degrees and higher will continue throughout the rest of the week. There may be a break next Monday, but the heatwave is expected to continue.
