During this intense heat wave, the questions are coming in fast and furious. Matt took a quite a few during yesterday's online chat but we've heard many more from CWG readers via post comments, our Twitter feed, and email. Here's a sampling along with responses:
@bowlernumberone (via Twitter) asks: Hot enough to fry an egg on the sidewalk?
Response: One of our readers (stinkerflat1) performed this experiment yesterday. Check out the video.
Mike (via email) asks: Is there a site where I can view the record heat for any particular day? Specifically I'm looking for the current heat record for Washington DC on July 7.
Response: You bet. The National Weather Service documents daily climate information on its website for DCA, IAD, and BWI. Today's (July 7) records are DCA: 99 (1991), IAD: 101 (1988), BWI: 99 (1993)
@omgapony (via Twitter) asks: Curious whether our 78-80 nighttime lows are also record highs for the dates?
Response: The websites for DCA, IAD, and BWI given above provide the record high minimum temperature data. As this morning's low was 80 at DCA, it appears it will break the record high minimum for the date of 79 (from 1999). Dulles, which dropped to 73, may have tied its record high minimum (from 1987).

Brandon (via email) asks: With it being so damn hot today, I wanted to ask what the top temperature in all of 2009 was for Washington, DC - as in, the high temperature for all 365 days of the year.
Response: The highest temperature in 2009 was 97 on August 10, 2009. I imagine many of us are longing for last summer's conditions.
@karenkraus (via Twitter) asks: There seems to be lots of poor air quality days lately. How does the temperature influence air quality?
Response: Yes. Hotter temperatures tend to make air quality worse. Read more at About.com.
@jrodfoo (via PM Update post): I remember a night in Aug of 2007 that was unbearable at 11:30 PM, it was like a sauna, Does anyone remember this? Gang? It was a Saturday night in early Aug of 2007 I believe.
Response: I remember it well. The humidity during that heat wave was worse than this one. We set a record high minimum of 80 the morning of August 8 followed by a record high maximum of 102 in the afternoon. (The evening prior was no doubt disgustingly oppressive).
