The Truth of a Heat Wave

It is insane when a temperature of 90 degrees and a dew point of 70 degress brings on a feeling of relief. In Wisconsin this feeling only takes place during an extended heat wave in the middle of summer. That is exactly where we are at. We've been doing our best to keep hydrated and keep the sunscreen applied while outdoors. As for being inside the house we feel very fortunate to have central air to keep things comfortable. Looking ahead there might be a 24 hour period early next week that provides some relief from the heat, but the heat will return and stay with us for another extended period of time. Anyone following the LRC theory (Lezak's Recurring Cycle) knew the recent warmth was coming with great potential to provide extreme summer weather. This part of the pattern has been documented thoroughly via LRC Weather, WeatherWatch12, and even here at OSNW3. This coming week is the pattern feature that brought us our first heatwave of the summer back in early June. The repeat looks to be a little less extreme than I had originally thought back on Jun-9 as it is taking on a look like it's predecessors from late winter and early spring, but never the less it is recurring and will be continuing the heat and humidity making the month of July a wonderful summer month for those still remembering our prolonged winter and cool spring.

The Dog Day That Will Not End
Over the past 8 days the max temp has averaged 87.7 degrees, the min temp has averaged 69.3 degrees, and the max dew point has averaged 74.2 degrees. The combination of each data point creates a hot and sticky situation. I like to define these types of days as "dog days". If our max temp exceeds 80 and our min temp stays above 65 on any given day, that day qualifies as a "dog day". We are well on our way to be competing with the numbers of last summer.

On a side note, since 1893, Oshkosh has endured streaks of 25+ days where the maximum temperature was 80+ degrees 8 times; 1908, 1919, 1921, 1930, 1963, 1966, 1983, and 1988. The longest streak took place in 1921, Jun 16 thru Jul 31, a whopping 46 days. During that period the average max temp was 90.7 and the average min temp was 66.5. It's average was a "dog day" by definition. Talk about hot.

Front Of House
We are deep into summer now. I hope the hundreds of thousands of folks that visit the EAA this coming week find ways to stay cool.

  4. SuzieE, I am happy to read that. I have been able to see a few planes fly over the house and see a few while driving back and forth to Sheboygan.

    How about the weather today, rainy with overcast skies, temp around 70. Almost perfect. :)

    Hi Josh!

    Well, tomorrow is the BIG day! Start of a new LRC season, right?? Seems to me you had a pretty good ‘rookie’ year. Many thanks for all the information you have prepared and shared. It’s been very informative and interesting following along with both of your blogs. Looking forward to more of the same.

    Cordially,
    Tony (Pl. Prairie)

  6. Hey Tony! The new WW12 blog is a bit quirky for me right now, technically speaking. The layout and functionality lacks compared to it's old format, imo, thus far. That alone is the reason I don't visit as often. But now with the RSS feed, I am reminded to visit. Which is good.

    About the LRC, I am fairly confident that the cycle doesn't change with a flip of a switch. I am trying to forecast what might happen in two weekends for our Oshkosh City Golf Tournament and I am seeing similarities to early September. My current thinking is true to the LRC and that as the jet starts to strengthen and dip south we will see a morphing effect and a new cycle will show it's face in Autumn.

    Behind the scenes here I've been analyzing similarities of cycles from year to year on specific weeks to see the differences in where the troughs and ridges setup time after time. I am about ready to paste that work into a blog entry. It's very interesting to see the 'same' 500mb patterns each year.

    However, each LRC is unique and with each passing season the overall look and feel of the cycle changes. The ever evolving aspect takes patience and time to keep up with it. I suppose I have a passion for it now... :)

  7. Oh, Tony, also, I think when the signature storm rolls back around (Aug 20 ish), where it's located and it's strength could be an indicator of how the cycle has morphed and perhaps a sneak peak into what is about to come for next year. ???

    All questions and ideas. It's an exciting time.

    Hi again Josh,
    Thanks for the reply; good to hear something from you. Quick note about WW12 blog: Due to the necessity of having to join U-Local to be able to post comments, I’ll only be following the blog as a ‘reader’. Not a technical difficulty for me but rather a personal one.
    My reference to a new LRC season was based on your LRC calender that began on Aug 1 of last year. Hope you will retain that as part of your LRC blog. I understand that we’re now into the wait and see what develops over the next few months. As I’ve said before, I’m mostly just a curious onlooker, but I am quite interested and excited to see what changes may come about.
    I went and dug up all the newspaper clippings I had saved during the 81/82 years. Quite fascinating not only for the weather around here but over much of the whole country as well.
    I’ll be watching both of your blogs for anything you might have to say about the weather; past, present, or future!

  9. Made it home from EAA in 15 hrs. Weather was great all week, yes, we even enjoyed the rain. A camping trip would not be complete w/o a good soaking or two or three :)... Interesting storm that came through on Sat. afternoon... alot of wind... gusty...even knocked portapoties down by our tent--with a nice rainbow to finish. Wed. we went to Rainbow Park to wash the mud from our feet. The water was surprisingly warm. My daughter is ready to move up north where the heat and humidity are more pleasant. Today we were greeted with 105 degrees. Please send some cooler weather down south. My garden is baking.

  10. SuzieE, the cool air arrived about a week ago. It's been great. Dew points are low which is the main factor. It'll get humid once again that I know.
