Think you know everything about the heat during the past two weeks? Think again.

Yes, the title says heat event. I didn't to call it a heat wave as the past 12 days haven't all been abnormally hot. As some of the days have, that's what I'll be addressing in this blog. I wanted to come up with a list of 10 things that you may not know about this current stretch of hot weather.

Updated (8/1 - 11:34am)

1. Today marks the 15th straight day at or above 93 degrees at Reagan National Airport. The record number of consecutive days at or above 90 degrees is 21 which happened twice before in 1988 and 1980. Our 7-day forecast shows 7 more days at or above 90 degrees, so it is possible we may approach that record in two weeks.

2. Today is the 39th 90-degree day at Reagan National, which is just 5 behind where we were at this point last summer.

3. A record 25 days at or above 90 degrees occurred at Reagan National for the month of July. The previous high number of days was 24 set in July 1987 and July 1993.

4. July 2011 in Washington, D.C. was the hottest month ever recorded, with an average temperature of 84.5 degrees. This is hotter than the record set last year in July of 83.1 degrees.

5. The high temperature of 105° at Dulles airport on the 22nd of July was the hottest temperature ever recorded for that station.

6. The heat index of 121° at 3pm on July 22 at Reagan National Airport was the highest heat index on record for that station.

7. Oddly enough, the July 2011 monthly average minimum temperature at BWI Marshall of 70.4 degrees ranked as the 24th warmest of all July's in Baltimore and was a tenth of a degree less than the monthly average minimum temperatures from last July.

8. 84° was the warmest morning low on record at Reagan National Airport. A side note is that this happened two days in a row on the 23rd and 24th of July. 

9. During the 21st through 24th, a new record was set at Reagan National airport for the most consecutive days with LOW temperatures at or above 80 degrees. The previous record was 2 straight days which occurred last year in 2010.

10. Reagan National set 2 record high temperatures and 4 (maybe the 5th tonight) record high minimums.

BWI Thurgood Marshall set or tied 3 record high temperatures and 1 record high minimum.

Dulles Airport set or tied 3 record high temperatures and 3 record high minimums.

Now for a nice chilly thought, let's watch Adam Caskey get pelted by snowballs in Dupont Circle!
