July 30: Lower Humidity!


Drier air is working its way into the Midstate from the north today, so the humidity levels will be dropping hour-by-hour.  Dew points were still in the 70s early this morning…for reference, here’s what the dew point equates to in real-world terms:
Dew Point Scale Increasing

By this afternoon, here’s what dew points will look like across the area:

Much better!  The lower humidity means that our hot temperatures this afternoon will feel “normally” hot — I don’t have to post a heat index forecast today:

More of the same as we head into the weekend…hot but not-too-humid weather should prevail through Sunday, with only a very slight isolated storm chance on Sunday.  The humidity will eventually creep back in next week, which will lead to a better chance of scattered storms by the middle of the week:

Weather, space, and some cool new tech in the nerd-links today…

  • Flooding has been the dominant bad-weather story across the country so far this year, and the looming El Nino could continue that trend.
  • Are heat warnings in the media over the top?  (Whenever I share hot-weather tips or talk about heat advisories on the air, I phrase the advice as being “common-sense” stuff…which it is.)
  • The title of this article says it all: “Pluto has an atmosphere, moons, and maybe geological activity.  Can we call it a planet now?”  (I’d say no: it’s smaller than our moon, it’s orbit crosses the orbit of another planet, the plane of its orbit is tilted significantly compared to the other planets, and it may not be the largest object in its own neighborhood, the Kuiper Belt.)
  • As fascinating as the new information from Pluto has been, I’m willing to bet whatever we would discover on Europa would blow that away.
  • The great thing about researching these links every day is that I learn something new every day…like the fact that right now the Milky Way is in the process of consuming several smaller galaxies.
  • The first instance of “northern lights” outside our own solar system has been spotted.
  • The previous article references brown dwarfs as “failed stars” — but are they really?
  • Love this: a new Braille smartwatch lets blind people read text messages.
