An Excessive Heat Watch is also in effect for Saturday. From the National Weather Service:

THE NATIONAL WEATHER SERVICE IN BALTIMORE MD/WASHINGTON HAS ISSUED AN EXCESSIVE HEAT WATCH… IN EFFECT FROM SATURDAY MORNING THROUGH SATURDAY EVENING.

* HEAT INDEX VALUES… AROUND 105 DEGREES THIS AFTERNOON. UP TO 110 DEGREES SATURDAY AFTERNOON.

* TEMPERATURES… AROUND 100 DEGREES THIS AFTERNOON AND SATURDAY AFTERNOON.

* IMPACT… RISK OF HEAT EXHAUSTION OR OTHER HEAT-RELATED ILLNESS FOR THOSE WITHOUT AIR-CONDITIONING OR THOSE SPENDING TIME OUTDOORS FOR AN EXTENDED PERIOD.

PRECAUTIONARY/PREPAREDNESS ACTIONS…

AN EXCESSIVE HEAT WATCH MEANS THAT A PROLONGED PERIOD OF HOT TEMPERATURES IS EXPECTED. A HEAT ADVISORY MEANS THAT A PERIOD OF HOT TEMPERATURES IS EXPECTED. THE COMBINATION OF HOT TEMPERATURES AND HIGH HUMIDITY WILL CREATE A SITUATION IN WHICH HEAT ILLNESSES ARE POSSIBLE. DRINK PLENTY OF FLUIDS… STAY IN AN AIR-CONDITIONED ROOM… STAY OUT OF THE SUN… AND CHECK IN ON RELATIVES AND NEIGHBORS.

TAKE EXTRA PRECAUTIONS IF YOU WORK OR SPEND TIME OUTSIDE. WHEN POSSIBLE… RESCHEDULE STRENUOUS ACTIVITIES TO EARLY MORNING OR EVENING. KNOW THE SIGNS AND SYMPTOMS OF HEAT EXHAUSTION AND HEAT STROKE. WEAR LIGHT WEIGHT AND LOOSE FITTING CLOTHING WHEN POSSIBLE AND DRINK PLENTY OF WATER.

TO REDUCE RISK DURING OUTDOOR WORK… THE OCCUPATIONAL SAFETY AND HEALTH ADMINISTRATION RECOMMENDS SCHEDULING FREQUENT REST BREAKS IN SHADED OR AIR-CONDITIONED ENVIRONMENTS. ANYONE OVERCOME BY HEAT SHOULD BE MOVED TO A COOL AND SHADED LOCATION. HEAT STROKE IS AN EMERGENCY – CALL 9 1 1.

      And your silicone implants for your hips
      Have slipped down to your ankles, mama
      You’re just busted
      Tu me oigo, si, right?

    I can roast my watermelon on the sidewalk instead of on Lucky Sevens roof today!

  • gordan ramsay

    I prefer Newport smoked watermelon in Lucky Seven.

  • Hank

    Good God that’s hot. We should all be allowed to wear nothing but white socks and Nikes for the next two days.

    • drax

      The ladies should be allowed to wear nothing but tube tops and bike shorts. For their own good.

      • Karl Rove

        I thought you’d switched to Serb lifeguard boys.

      • Grindr

        Karl Rove is now 666 feet away.

    It’s been 95+ seemingly every other day for the 4 summers I’ve been here, but yet they say the average summer temp is still 83 or something…I think there must be data from the last Ice Age dragging down the mean…

    • D’oh

      Overnight lows

      • CW

        Nah I mean avg daytime high, not 24/7 mean.

    • Opie

      Today’s average high is 88, average low is 71. I don’t know if they track such a thing as an average temperature.

      I don’t know where this article got the information about potential 103 and 102 degree temperatures. That is not reflected in the NWS statement. WTOP had an article yesterday and said something like “the mercury could touch as high as 110”, when clearly they meant the heat index. That’s not to say you could find someplace where heat may build up to 110, but that would not be an accurate measurement of the local air temps.

      But I know if you go with some of the private websites that use local observations and algorithms you can get some pretty wack predictions. I saw one for my neighborhood that predicted 107 today.

      • CW

        I meant daytime high, yeah, and also I, not being a meteorologist, do wonder where they take the official temp readings. A lot of them are at schools or airports, but I’ve never sen the specific thermometer location. Is there an official, idk, maybe NIST/ANSI/ISO standard for setting up a thermometer? I.e. it has to be X meters away from bodies of water, shaded/unshaded, how much asphalt, how much reflected light, etc. etc.? Is sunlight allowed to impinge upon the measuring device? I mean today it could be 90 in the shade at Washington-Lee, 85 paddleboarding on the Potomac, and 110 six feet above the tarmac at National. So is there something that defines an “official” temperature?

        • JohnB2

          From the meteorology class I took in college, many of the official weather stations are louvered (sp?) white boxes (around 18″x18″x18″) that ventilate and shade the equipment and are around 4-5 feet off the ground. That was a few years ago so I dunno what they’re like now.

          • CW

            Thanks! Learned something new!

          • Opie

            You have to get into dry-bulb and wet-bulb and all kinds of stuff. It’s way beyond me.

          • CW

            Yeah, psychrometrics has never been an area of my expertise.

  • Arlington cat

    Wear something short and flimsy, gals.

    • brian

      watch out for men eating other humans and having it blamed on bath salts

      • TeenBoarderDude

        Use a little extra Axe everyone!

      • CW

        And dogs now too, at least in Texas.

        • Chocolate Laboradorable

          gasp

      • Id

        I love finger sandwiches!

  • Thomas

    It’s the summer……

  • Michael H.

    This month was actually mild as far as Washington summers go, until this week.

    As for today, Weather.com shows a forecasted high temperature of 103F and a heat index near 110F.

    • JohnB2

      We had some nice, almost chilly weekends in June.

  • C02isYourFriend

    oh cmon, its summer.

    Summer is supposed to have 103 degree days and risks of death from heat, right?

  • Bluemontsince1961

    Well, by me, this is better than snowmageddon.
