Dew Points!

During this year's heat wave I learned something new about the heat index that I didn't know before. I had always thought that the high humidity levels were the major cause of the high heat indexes but, on this past Tuesday when the heat index was 108 degrees. I noticed that the humidity levels weren't that high and the dew point levels were. The humidity level was 46% and the dew point level was 70. So I learned that the high dew point levels were the cause of the high heat indexes not the humidity levels. Although they can still help to rise the heat index though. So, that means that having a chance for rain like we did on Tuesday is not necessarily a good thing because if we don't get the rain and we get really high dew point levels then it could make it seem a lot hotter outside. Which isn't good for a city like Houston that already gets hot temperatures during the summer months. I'm glad that we've been getting some rain though.

    that was a good explanation about the dew points; I was somewhat familiar with what they were, but I think you described them very well here! I know when the dew points are high here, it does seem more hot and humid!! Hoping you get more rain too!

    have a good weekend

Toy Cars And a New Computer!

Image
Look at all of my toy cars! I was just organizing them before I put them into a different box, but I had to move them a little early to make some roof for my new computer! So back into the box they went! I've always wanted to arrange my toy cars like this since I was a kid, when I would see them arranged like this in toy car collector magazines and books, I thought it looked pretty cool. Anyway I had to get a new computer because my laptop's screen finally went out and it was becoming slow. It would sometimes take couple of minutes to load a webpage, so I knew I had to get a new computer. I got a Lenovo from Microcenter. It's refurbished, but it looks and works like new. Microcenter also gives you a keyboard and mouse, but it doesn't come with a monitor unless you want one, but it will cost you  a little extra. The whole computer with keyboard and mouse cost a hundred dollars with thirty dollar shipping, very cheap and works better than my laptop.  The rea

White Lies

She smiled through her white lies as she wandered from table to table. Being a waitress was not one of her funnest jobs and she didn't feel like explaining the menu to every single person. "IS THAT FOOD GREAT?" "IS THAT FOOD GREAT?" "IS THAT FOOD GREAT?" "WHAT DO YOU RECOMMEND?" "They are all good!" she would say with a wearied smile. She didn't think that the food was all that good though, except for maybe the hamburger, but even that wasn't all that great either and she wanted to tell the truth, but it was her only job and she didn't want to lose it. Wandering and wandering through the tables day in and day out. Until one day she collapsed and it happened, the pasta fell all over the man in the suits shirt. "I ordered the food to eat it, not wear it!" Said the man in the suit with a sarcastic tone to the waitress. The waitress looked at the man in horror. "I'll..I'll...clean it up" she
