BWI reached 74 degrees by 9 a.m., 79 degrees by 10 a.m. and matched Tuesday's high of 85 degrees by noon Wednesday. The Inner Harbor reached 90 degrees by noon, according to the weather service.

Winds around 10 mph were expected to increase in the afternoon, to 15-20 mph. The warm breeze is coming from the southwest, as a system known as a Bermuda high circulates air from the Gulf of Mexico up into the mid-Atlantic.
Partly to mostly cloudy skies were forecast throughout the day. Scattered thunderstorms are possible along the Mason-Dixon Line in the afternoon, with the potential for strong gusts and hail, according to the weather service.
Wednesday night could again bring lows in the upper 60s, rising to the mid-80s before a cold front with a chance of thunderstorms arrives overnight Thursday into Friday.
Friday, temperatures are expected to drop back into the 60s and lower 70s.
Sunny skies and seasonable highs in the 60s are expected for the weekend.
