Unusual Weather Event

 Not sure what caused the unusual "hump" in the weather recordings today, but a few things stand out.


 

The barometer took a "dip", while the wind speed and direction shifted dramatically. The temperature went up twenty degrees for about 2-1/2 hours, and the humidity took a corresponding drop.

I'd put this down to a "Downslope Wind Event", or Chinook, but the wind was from the Southwest this time, so not much "Downslope" from that direction.

Since I wasn't awake at the time, I don't know what the radar was showing.

  1. We're also having a late "Indian Summer" day today. High near 88 f. and the lows above 60. We'll take it!

    1. It's been in the sixties this last week, and will be in the sixties until the end of this week. Then I'm pretty sure Winter will return until Spring! Got a lot of things to do this week, and not much energy to do them with...

  2. Wind speeds in Wyoming can reach level 3 hurricane standards. Those 48 14,000' mountains protect us. Might have been a system moving through North of us.

    1. My weather station isn't mounted in the best place, but it's the best I could up with given the layout. The "standard" is to mount the anemometer at 31' AGL, but that would be on the roof, and that's not gonna happen.

      I'll have to look around for some on-line Olde Skool weather maps with the isobars on them, like I used in ground school. Those things I can read! I can receive the WEFAX broadcasts and decode them, but they're for mariners, and don't do much good to a person in Colorado!

  3. The weather in Northern Arizona is quite mild. Very pleasant. Indian Summer indeed.

    1. It's been beautiful here, too, the last week. The dog just loves her walks, and gets all spunky in the cooler weather.

  4. Pleasant here, if a little chilly at night. Do you feel our Old Enemy, the Weather, is lulling us into a false sense of security?

    1. Not sure, Parson. One of my (few) Ham Radio friends here, and a life-long resident, was telling me the other day he thought we'd have a drier, warmer Winter this year.

      We haven't paid algore's weather tax, so who knows what the coming months hold.....

  5. Hi drjim,
    Interesting charts. If you don’t mind my asking, which weather station do you use? I’ve had a Davis VantagePro2 for several years and it’s just about dead. It’ll cost almost as much to replace the sensors as to buy a new one so I’m shopping around.

    1. I'm on my second Davis Vantage Pro2. The first one (which still works 100%) I bought I had up for about 14 years in Torrance and Long Beach. I bought a replacement with the wireless option as I didn't want to run a cable this time between the station and the house.

      They're not cheap, but mine's been 100% dead reliable, and I'd buy another if I needed a replacement.

      The first software I used was "WeatherView", but the guy who wrote the program no longer supports it, so I went with "weewx" this time.

  6. Yep, chinook, but the WARM kind. That was desert air, as shown by the humidity drop.

    1. This is the same type of event I saw a year or so ago, but this time had the very pronounced hump to it.

  7. My long haired dog sheds spring and fall. He hardly made a mess this year. I expect a really mild winter in east Texas.

    1. Ours is short haired, and she sheds twice a year, too. I've never bothered to keep track of her shedding vs winter, as it didn't matter back in SoCal.

    2. Dog's around eight. My first long haired dog. Took a few years for me to notice he didn't shed the same every summer and winter. Not quite certain how to interpret spring shedding yet, but I've been successfully using the fall shed as a guide the last two winters. So, not enough track record to say it's valid, just something I've been looking at. It'd be cool if it was statistically useful, but if it's so good, howcum I never saw it in the Almanac? I'm pretty sure people who were smart enough to figure out lunar phases and planting, etc. were all about
      Connecting Dots..
      Maybe what I'm seeing is pure coincidence.

Keep it civil, please....

Gloomy, Gritty, Grey Day

 At 1700 local it's as described in the headline; 30*F, 88% RH, completely overcast, snowing like crazy (small flakes, but lots of them)...
