96 degrees downtown at 10 a.m.
It's already 96 degrees at 10 a.m. here at The Sun's weather center at Calvert and Centre streets. The downtown forecast calls for a high Tuesday of 104 degrees.
The airport is a few degrees behind us, at 94 degrees. But with another six hours or more of heating ahead, there seems little doubt we will reach or surpass the 100-degree mark today in both places, and set a new record high for the date at BWI.
We're not likely to see any relief until Thursday, and we'll not leave the 90s until the weekend.
Here are the targets at BWI-Marshall for the next few days:
Tuesday: Forecast - 100 degrees. Record - 101 degrees, set in 1999
Wednesday: Forecast: 100 degrees. Record - 99 degrees, set in 1993
Thursday: Forecast: 91 degrees. Record - 100 degrees, set in 1993
Friday: Forecast: 93 degrees. Record - 103 degrees, set in 1936
Saturday: Forecast: 88 degrees. Record - 107 degrees, set in 1936
Sunday: Forecast: 88 degrees. Record - 100 degrees, set in 1988
We can blame the heat on the large high-pressure system still parked over the eastern third of the nation. Until a cold front moves in from the west late on Friday, we won't see much relief. The front could bring us some welcome showers and thunderstorms, and can be expected to bring daytime highs closer to the average for this time of year in Baltimore.
The hottest period of the year, on average in Baltimore, runs from July 16 to 25, with a long-term average of 88 degrees. After that, the numbers begin their long, slow slide toward winter.
