Courtesy of our friends at the National Weather Service forecast office in Sterling, Va, consider how hot it has been at this time the last three years:

HIGH TEMPS:

          BWI         DCA
7/23/11   102         102
7/24/10   101         101
7/24/11    98          97
7/23/10    98          98
7/24/12    91          93

In light of that punishing heat, I think both what’s here (low 80s this afternoon) and coming our way are well-deserved.

Check out the high temperatures for Thursday projected by the GFS model:

Now look at the delightful dew points Thursday morning forecast by the high resolution NAM model:

As a refresher, dew points are the best available indicator of humidity.  Dew points from 65-70 are borderline uncomfortable, 70-75 are pretty gross, and when they’re over 75 – see late last week – they’re downright oppressive.  By comparison, tomorrow’s 50s are literally a breath of fresh air.

The best part of the current weather pattern: there’s no extreme heat on the radar.

As the NWS in Sterling puts it:

ONE WK TO GO IN JUL AND NO 90+ TEMPS IN SIGHT.
