The hot weather spell arriving Wednesday could break multiple records. With high temperatures predicted in the upper 90s Wednesday and Thursday, records of 100 degrees for both days could be challenged.

The National Weather Service was predicting highs of 98 degrees Wednesday and 100 degrees Thursday, as of Monday night, though the predictions have fluctuated as the heat gets closer. A heat advisory could be issued Wednesday.

Lows are forecast at 80 and 79 degrees overnight, also vying to top records for the highest low temperatures of 78 degrees Wednesday and 79 degrees Thursday.

It will surely be warmer than those temperatures in some areas, but BWI Marshall Airport is the site for record comparison.

A record hasn't been set at BWI since April 16, when the high of 90 tied a record set in 2002. Before that, a record high minimum temperature of 59 degrees was set March 21, and a record 1.64 inches of rain fell March 1.
