A Sweaty Evening

Dewpoint Temps Have Jumped To Around 60 This Evening Due to the Showers

Dewpoint Temps Have Jumped To Around 60 This Evening Due to the Showers

I took a bike ride this evening and made it back just before the larger raindrops arrived. It was definitely a bit humid so those clothes will be heading straight for the washer in the morning.  Some showers made it over the the Cascades and moved down into the Portland Metro Area this evening.  They’ve generally been weak, but one very small cell southwest of Forest Grove appeared suddenly and spit out about 5 cloud to ground strikes according to our lightning data.  The next closest strikes to the metro area were around Zigzag and Welches…lots there between 4:30-5:30pm.

Dewpoints have jumped to near 60 degrees, in fact I’ll probably mention it during the 10pm newscast, even though the bosses generally cringe when they hear the word.  It is a complicated concept, but just remember the higher the number the larger amount of moisture in the air.  The reason I don’t like to use relative humidity is that it’s…well…relative.  It goes up and down dramatically each day while the dewpoint only changes when the actual amount of moisture in the air changes.

Looking ahead:  Pretty slow weather next week…a bit of warming with higher upper-level heights early in the week then some sort of lower heights with some more moisture (from the west this time) later in the week.  Enjoy the weekend because it looks like a decent one for mid-June.

    Here is a high resolution radar image of that storm for memory!

    Gosh, I really miss June 4, but we have to move on…

      Lol I concur. I went fishing in the same spot today as I did that day, but when I left there was no wall cloud or ferocious winds combined with driving rain. It just wasn’t the same 😦

    • Timmy_Supercell (Hillsboro) says:

      Yeah exactly. You were probably at the edge of the storm since it split in two before reaching me. I did get a lot of blowing dust that forced me inside from my deck though! lol

      There is a chance we may see another similar storm this summer. 🙂

    Perhaps some storms on Friday? Showers moving in with the posibility of some sunshine in between the showers during the afternoon. And with instability + cooler temps we could see a few storms. If anything, we might see pulse like storms that will just dissipear within a 15-20 minute period. Surface CAPE of 500 J/kg according to the 2100Z scan on Friday. Its a chance.

  4. Hmmmm….. well…the morning started off clear and sunny (and mild, temp-wise) but it’s now cloudy (clouds started rolling in here around 9:00-ish) and a bit cooler. Temp here was 64.2°F just before 8:00 but it’s now down to 62°F. Certainly no “cold spell”…

    Regarding snow… well….I love the snow enough to tolerate shoveling it… And, as long as I can fire up my smoker, I’m happy! (and I did plenty of both last December…) 😉 I’d happily accept another round of that! 😀

    Timmy, think it’s just boring boring boring in the weather department, no real excitement on the horizon either.
    …Or it could be that we are headed toward a possible horrible winter (if you’re a snow lover) with El nino, +SST, and maybe a +PDO…that could spell death to any chance at winter we have…hope the trends change!

    • Timmy_Supercell (Hillsboro) says:

      I am not too much of a snow lover, I can do without a couple cold snowy winters. Its thunderstorms that get me going. As far as t-storms go, we have been in the right direction for that. So I am satisfied nonetheless.

    • Timmy_Supercell (Hillsboro) says:

      There is something bad about rising sea temps, because that only increases the chances of another potentially historical cyclone like the December 2007 Gale. It sure was a warm one that December (if I remember correctly it was in the mid 60’s some days).

    • Timmy_Supercell (Hillsboro) says:

      Just looked at Wunderground history data, guess it wasn’t that warm. The warmest was 60F on Dec 4th, right when the storm ended. Then it was mainly in the mid 40’s afterwards.

  6. Timmy_Supercell (Hillsboro) says:

    Or maybe I scared everyone?

    Alright, severe thunderstorm warning is cancelled, we aren’t gonna have anything! lol

    And here goes the silence again…

    ps: “we need a new post”
