    Good short read from AlabamaWX

    DISCUSSION: As many parts of North America and Europe begin to prepare and brace in earnest for the onset of the peak severe weather season during a typical calendar year, there a number of premiere issues which are worth understanding. That is, so everyone can have a better idea of how the atmosphere works and why various atmospheric phenomena evolve the way they do. One such example is understanding the different types of wind shear which can occur and their respective relevance.

    To get started, wind shear is a naturally occurring aspect of the atmosphere which affects both atmospheric phenomena such as various types of convection as well as all aviation-related concerns. More specifically, wind shear comes in two primary forms which includes speed shear and directional shear. Speed shear is best characterized as any situation in which the wind shear changes in value from two given elevation points. Thus, when speed shear is present, this can often lead to situations in which there are convective storms which do not last for an overly long period as a result of core updrafts being tilted too much. Therefore, with too much speed shear, various thunderstorm forecasts can often end up being a bust in terms of forecast verification.

    The other primary type of wind shear (as noted above) is known as directional shear. Directional shear is best characterized as any situation in which the direction of winds at two given points of elevation are different from one another. Often, when there happens to be rather large amounts of directional shear, there are frequent impacts to aviation safety in terms of crosswinds at any point during any flight (regardless of aircraft size) as well as to convective storm development. Impacts to convective storm development are quite often realized by way of there being a greater potential for the development of convective storms with rotating updrafts. Therefore, with greater amounts of directional shear, there can often be a greater threat for supercell thunderstorm assuming all other convective environmental conditions are conducive for supercell thunderstorm development.

    Thus, this goes to show that whenever there is a substantial presence of speed and/or directional wind shear in the atmosphere, there a host of different considerations which always need to be made when it comes to both aviation and forecasting interests.

    So this happened the other day. About 3:45p on Tuesday, 4/2, I get a weather alert from one of my weather apps saying severe weather OTW.

    I am building a 5 story hotel, this is important.

    I go out of the project trailer, and look to the North which is where it was coming from and I see one of the blackest clouds I have ever seen and it was shooting lightning. I immediately call my mason and tell him to tell his guys to drop the tools in place and get off the deck LIKE RIGHT FUCKING NOW!! 10-12 minutes later, the sky opens the fuck up in TORRENTS!!!

    So I go run into my trailer because I thought it was just a T storm and I was just going to get on the computer and do office shit until it was over. Well, suddenly out of no where the wind picked up and I am looking out the window and I can't see shit its blowing so hard. The trailer is rocking back and forth, my admin girl is freaking the fuck out and I'm starting to think maybe we shouldnt be in the trailer. So I go back to the window and look out again and I see sheets of ply wood flying through the air, for us to mad dash it into the concrete building its about 100' through a gauntlet of flying debris, so......noooope, not doing that, guess we have to ride this thing out.

    What I did not know at the time was we were under a tornado warning and I later learned that that's what it was, a small tornado. Powerlines went down, trees went over and my building suffered below.

    Needless to say it was gnarly, I am just glad that the wind was blowing with the long way down my trailer and not hitting us broadside. I am positive the trailer would have rolled. Especially after you see the pics below.

    This wall was empty cell CMU at the time. We just weren't ready to pour it yet.
    upload_2019-4-4_14-41-25.jpg

    This wall was filled full of concrete that morning and it still went over. Still to green to support it.

    I have to say, these were paracord tied down to sand filled buckets, I cant believe they stayed in place and just got crushed from the wind.

    upload_2019-4-4_14-45-50.jpg

    This is #8 rebar that got bent over like nothing.
    upload_2019-4-4_14-47-29.jpg

    Not an experience I want to relive. I've never been in one before and I will say I could have gone through life with out it. Luckily I made the call when I did because the masonry crew rode it out on the 3rd floor and when they came out they were terrified, my iron workers rode it out on the same floor different area and I have to say that 4 pretty rough dudes were white as sheets. So I dont know who was more scared, us in the trailer or the guys in the concrete building with no windows.

    Wow thanks for sharing! Definitely a life threatening situation there. Not really any safe spot in that situation. I think I'd go with the building, but with it being unfinished......that's a tough decision. Glad everybody was OK

    Has the US not deployed a cellular network based warning system yet? In Canada now when there is a severe weather warning all cellular phones within the warning area get an alert immediately. It comes though even if the phone is silient as a long vibrate. It’s also used for missing kids when the suspect is likely nearby.

    We have it. I just didn’t get it.

    I get amber alerts all the time. Just not this time. Unfortunately.

    Going to be rough tomorrow for Northern Louisiana and Southern Arkansas! Please pay attention to the weather if you are in these areas. Please!
    The moderate risk puts you at a 45% chance of severe weather within a 25 mile range of any location in that risk area. If you do not live in a site built home find a safe place to go tomorrow. Just have a plan!

    Day 2 Risk Area (sq. mi.) Area Pop. Some Larger Population Centers in Risk Area
    MODERATE 32,038 1,428,252 Shreveport, LA...Bossier City, LA...Monroe, LA...Greenville, MS...Vicksburg, MS...
    ENHANCED 42,373 2,313,676 Jackson, MS...Tyler, TX...Longview, TX...Pine Bluff, AR...Alexandria, LA...

    It looks like the risk for Sunday has shifted a bit. But, like James Spann says, don't get caught up in the colors and lines. There is a threat of Severe weather this weekend so be prepared.

    I saw yesterday you guys had some severe. A meteorologist that used to work in Alabama moved up to that area. Vernon Turner. He's pretty good. I think he might be in Charlotte.

    New forecast trending worse than this morning. Remain weather Alert.



    ...Synopsis...
    An upper trough will amplify as it approaches the lower MS Valley
    with mid to upper winds increasing to 60-80 kts. At the surface, a
    cold front/outflow composite boundary will extend from eastern TX
    into AR in the morning, and will shift east through the period.
    Ahead of this early activity will be a deepening surface trough.
    Preceding the front and early storms, southwesterly low-level winds
    will create a surge of theta-e across LA, MS, and AL during the day,
    with mean boundary layer dewpoints increasing to 68-70 F.

    Very strong large-scale lift will develop over the lower MS Valley
    during the day, with intense deep-layer differential divergence.
    Cooling aloft will also accompany the cold front, further aiding
    destabilization. The result will be widespread thunderstorms, with
    corridors of damaging wind and tornadoes.

    Mornin' folks :hattip:

    Louisiana and Mississippi you're under the gun today. Stay weather aware and have multiple ways to get warnings. Alabama, we get it tonight.

    STP4-18-19LA-MSDay.jpg


    Weather overnight tonight. The hatched area (within the 10%) means a chance of strong tornadoes EF2-EF5. 10% chance within 25 miles of any given point in that hatch. Very unstable air down south. Keep in mind the entire state has the threat of severe weather including tornadoes.

    Have something that will wake you up if a warning is issued and you're in the polygon.




    [​IMG]

    This evenings STP. The gulf coast will be under the gun.



    Keep and eye on the weather
