    All 3 globals have a heavy synoptic rain event on Friday with a low on the coast getting pulled into a front coming in from the Midwest. Then another early fall airmass behind it.

    I’m playing in a golf tournament on Friday, so let’s leave the rain for a little later in the day. Thanks.

  2. Closest CoCoRaHs recorded 1.95", which I think tracks given that we got nicked by that super heavy downpour in the morning and then had decent rains for quite a while in the evening (never got the really heavy stuff).

    Misting out there now.

    That extended to MBY in Burke.

    Home is on the eastern edge.  0.30” so far.  
     

    Im at the office and I can hear Yoda’s cell, though.

    Yeah...good storm. Plenty of T&L and heavy rain right now.

    Yes, let’s have these storms just sit on 66 for the next 5 or so hours.

    Are you in that one or are you just on the eastern edge?

    I need that complex to either sag south about 8 miles or build over me!

  5. Ended with about 0.6" yesterday here in my little corner of Burke. Quick hitter, but it dumped.

    Hoping we have decent weather for the last weekend of the neighborhood pool, then next week it's looking like an acceptable week for the pool to be closed (seems like it's always the other way around!).

    Unpopular opinion…could be 5 degrees warmer. Much nicer in the sun…little on the cool side in the shade with the breeze. Wfh today, so just sampled this on my balcony lol. It is biking weather tho…might have to partake later.

    Only reason I'd want it warmer is to take advantage of the last couple weeks of the neighborhood pool being open. Friday evening and Saturday should be great.

    DC appears to have recorded an August 20 high of 76 or lower 16 times in the 125 years between 1900 and 2024.  Rainfall was recorded on 10 of those 16 days.  So, to answer @mattie g's question, it appears to be an uncommon occurrence on a day with full sun.

    This morning's DCA low of 59 ties for the 10th coolest August 21 low since 1900.  The last time that a cooler low was recorded was in 1969 (58).

    Totally missed this point. Thanks for the research into it!

    Yeah, it was an anomalously “cool” day even if not unprecedented or record breaking. 

    Exactly. 76 on August 20 isn't wild in and of itself, but the fact that it only got to 76 without precip and/or thick cloud cover is what makes it impressive.

    Probably many.

    There have been 7-day stretches entirely in the month of August in DC where the average maximum over that stretch was less than 70F.

    As recently as 1992, there was a 7-day stretch with an average maximum lower than yesterday's 76F.

    The stretch in 1992 saw measurable precip on every day from August 12-18 except for the 14th, which had a Trace, so I'm guessing there were plenty of clouds during that entire 7-day period.

    My point is that a having day with partly cloudy skies only get to 76 at DCA is incredibly impressive. Add in a similar day today and you have to admire that!

    I think he's ranking by unique values. He corrected it to 10th place in a follow-up. If so, that's true. There's only 9 lower unique values on record - 67, 68, 69, 70, 71, 72, 73, 74 and 75. Although many of these have been reached dozens of times each.

    I wonder how many of those were reached on days without full clouds and precip. It's also more impressive that this was done on August 20 and not later in the month.
