    I think there’s quite a bit of question if our low of 74 holds through midnight, but if it does, it’d be only the second time since records started being kept at the airport that a low of 74 has been recorded this early in the season (6/8/08 had a low of 75).

    This went ENH for our area with the latest SPC D2 outlook.

    Yikes, that dewpoint at CMH is 82.

    12z HRRR has us getting to 97 tomorrow but first of all, it’s the long range HRRR and second of all, everything else seems to have at least some rain/storms and 90 is indeed a struggle on some models.

    Don’t get me wrong, the GFS and CMC also mix dewpoints into the comfortable range down there, but upper 50s, not near 40, and I think that’s probably more reasonable. Makes sense to me that temps would torch if humidity cratered like that under a massive ridge. I just don’t see it happening. Regardless, signs are definitely pointing to the ridge reloading next week, perhaps with a vengeance.

    I have a hard time believing dew points will be in the low 40s in South Carolina in late June, especially while it’s muggy up here, which is what I would think allows those readings to be achieved.

    This is starting to look like a good call.

    ORD, not ORH.

    Yes, but aren’t some of the ingredients somewhat lacking in C PA even if it does track that way?

    PBZ wrote up a decent discussion of the potential derecho.

    Best support for eye-popping temps is probably that the latest GEFS ensemble mean for 18z Wednesday is 96. None of the op models or other ensembles have us quite that hot.

    Feel like I read a book once about losing people to a chocolate factory.

    A real no doubter of a heat wave is on its way so we stop quibbling about it, I’m sure.

    PIT had a day during that Feb 2018 stretch that was 78/59, so we got some CDD’s there. Hitting 70 five days in a row in January would be incredibly anomalous in its own right.
  15. TimB
    CDD is mean temp over 65. Looks like that day had a high of 79 and a low of 43, so a mean of 61 and therefore 4 HDD.
  16. TimB
    With option 1, can a date range be put on it? If not, then a 5 day stretch of high temperatures in the upper 40s in January would qualify.
  17. TimB
    I’d say low 90s is noteworthy when it’s a double digit + departure, like now. But what’s the average high at MDT in July? 87 or so? Is 5 days of a +3 departure really noteworthy?
  18. TimB
    I would describe both July 2020 and August 2021 as “hell on earth”, though neither one was shattering daily records.
  19. TimB
    So a 5+ day streak is occurring about once a year and a 7+ day streak is happening about once every 3 years. To your point, August 2021 had a 5 day streak and a 6 day streak. July 2020 had separate 5, 6, and 7 day streaks all contained in the same month. And so on…
  20. TimB
    I could have worded mine better too. I didn’t include the shorter streaks in with the longer ones, so you’d really have to add stuff together since an 11 day streak is by definition a 5+ day streak, etc.
  21. TimB
    MDT has: 5 runs of 11 days 5 runs of 10 days 6 runs of 9 days 12 runs of 8 days 18 runs of 7 days 22 runs of 6 days 46 runs of 5 days So 114 streaks of 5+ days in 134 years, 46 of which went a week or more.
  22. TimB
    The fact that a rise of 1°C corresponds with a rise of 1.8°F ensures that the possible 5-min obs always go up in increments of five odd numbers, then five even numbers. An odd quirk, but an odd quirk with an explanation.
  23. TimB
    We did get to 88 officially, so warmest of the year.
  24. TimB
    High was 87 through 5 pm, so only tied for the warmest day so far.
  25. TimB
    This is starting to feel like one of those summers that doesn’t hit 90.
