The high temperature yesterday at my station was 99.2 and the heat index was above 115 at times. Today will be a few degrees warmer with highs over 100 degrees. Today will be the hottest day of the year thus far (we hit 100 on June 9th) and the heat index will again be over 115.
The Excessive Heat Warning continues today and is now extended to tomorrow. Tomorrow’s highs will be near 100 with heat indices again around 115.
Also today, the Maryland Department of the Environment has issued a Code Red Air Quality Alert for the Baltimore Metro Area:
A CODE RED AIR QUALITY ALERT MEANS THAT AIR POLLUTION CONCENTRATIONS WITHIN THE REGION ARE UNHEALTHFUL FOR THE GENERAL POPULATION. THE EFFECTS OF AIR POLLUTION CAN BE MINIMIZED BY AVOIDING STRENUOUS ACTIVITY OR EXERCISE OUTDOORS.
The good news is that the end of the heat wave is in sight, as a cold front will begin to move in tomorrow night, bringing slightly cooler air and possibly showers and thunderstorms tomorrow night and Sunday. The humidity will continue to be high, unfortunately, until a stronger front pushes through Monday night and Tuesday.
Thunderstorm chances continue into Monday when the second front moves through, dropping our temperatures back to near normal (upper 80s to low 90s) for the rest of the work week.
