After 10 straight days with highs above 85 degrees (today should be the 11th, with a forecast high of 92), we're headed for some much nicer weather as we get over the week's hump. The break comes tomorrow, after some overnight rains and the arrival of a front from Canada. The high Thursday should be around 80, with more rain Friday, followed by a beautiful weekend with afternoon highs around 75 degrees.
Normal - that is, average - afternoon temperatures at this time of year are about 83 degrees, with overnight lows in the low 60s.
Hard to believe it's only been since June 4 that we moved into above-average daily temperatures, after 19 straight days in May and early June with below-average temps. It was 12 days ago that the afternoon high at BWI was 64 degrees. On June 1, the mercury dipped to 51 degrees overnight.
