Good afternoon and happy Saturday, Region Rats!

The first thing I need to bring to your attention is that Da Region will be under a Wind Advisory from 6 PM CST Sunday until 6 PM CST Monday. Westerly winds of 25–35mph are expected along with wind gusts of 50–55mph.

Secondly, thanks to the unseasonably warm weather we've been having, we have an equally unseasonable—albeit marginal—risk for severe thunderstorms tomorrow. (As seen in the image at the bottom of this post.)

The only forecast hazard with the severe storms will be damaging winds.

The risk of hail is below 5%—which it typically sits at with any severe weather that isn't projected to contain hail—and tornadoes aren't forecast to have any increased risk in Da Region.

As a note, counties (I almost didn't notice that I initially missed the 'o' in that word; man that would've been awkward) south of Da Region do have a 2% risk increase of tornadoes with these storms.

Our high tomorrow will be in the mid-to-upper 50s—with the potential of localized temperatures in the low 60s—until the system bringing us this system fully rolls through.

Many of the storms *will* be strong even if they don't hit the requirements to be classified as severe. (Wind speed will determine the classification of the storms.)

Isolated-to-scattered rain is expected to start in the wee hours Sunday and will become widespread in the late morning/early afternoon.

The storms themselves are expected to arrive in Da Region between 11AM—1PM CDT, and they have the potential of popping up off and on until the late afternoon/early evening hours.

By midnight, the temperature will drop into the 20s before reaching the mid-to-upper teens around 6 AM Monday, and Monday's high will only hit the low to mid 20s, and high temperatures from Monday onwards.

The strong winds on Monday coupled with the cold temperatures means wind chills will be down into the single digits. 🥶

I highly recommend scarves, gloves, hats covering your ears (or earmuffs), and thick socks (or layers of thinner socks) as frostbite can occur with such cold windchills, although it will take longer than it would in colder temperatures.

Frostnip (stage 1 of frostbite) will be the most likely occurrence, which is when your skin turns red or pale—the paleness is especially likely in those of us with Reynaud's—often along with numbness, pins-and-needles, or tingling in your fingers, toes, ears, or nose. (Hey, I'm a poet and didn't know it, LOL!)

With the rain and subsequent rapid, extreme drop in temperatures, icy conditions on pavement will be highly probable.

Always keep BARFF (Bridges And Ramps Freeze First) in mind, and be especially careful when driving on them.

I'm not going to lie, BARFF has to be the funniest and most memorable acronym I've ever heard, and hopefully it will stick in your head as much as it does mine. 😂

From Monday until the at least the 10th—which is as far as my forecasting programs will predict with any remotely reasonable degree of accuracy—highs are currently expected to range from the 20s to the low-to-mid 30s.

Overnight lows are expected to be in the teens-to-20s, although even on nights with lows in the 20s the "real feel" will still be in the teens.

I'll likely post an update tomorrow if there are any changes in the forecast or if additional watches, advisories, or warnings are issued for any county in Da Region or the entirety of Da Region itself.

Finally, I'd like to wish a belated Happy Chanukah to my Jewish followers, a belated Merry Christmas to any of my followers who celebrate the holiday (whether your celebratkon is religious or secular), a Blessed Yule to my Pagan followers, a Happy Kwanzaa to anyone who observes it, and a Happy/Blessed/Merry holiday(s) to anyone who observe(s/ed) any recent or current religious or secular holiday(s) that I may have missed—I'm pretty sure I covered them all, though, LOL!

I hope you all have a great weekend and that you all stay dry, warm, and safe.

A general—but potentially necessary—note about my posts: Yes, I use en dashes, em dashes, Oxford commas, semicolons, and generally proper punctuation and grammar, but I do not—nor will I *ever*—use ChatGPT or any other AI in any of my posts.

Anyone who accuses me of using AI in my posts will quickly find out that while I'm generally quite a nice, kind, civil, and laid-back person, I'm very capable of throwing verbal hands like you would *not* believe, and I will have not one problem with—nor the tiniest of regrets from—doing so.

I'm an autistic grammar nerd, and this is just how I write. The frequency with which I'm accused of using AI on my personal social media accounts on every platform I use is, quite frankly, mind-blowing, exhausting, and ridiculously frustrating.

Just putting this out there:

It's not a blizzard; it's a snowstorm.

Blizzards require sustained winds of 35+ mph or very frequent gusts of the same and a visibility level of ¼ mile or less, and *both* conditions must last for at least three hours.

The amount of snow does not impact whether it's a snowstorm or a blizzard. Blizzards can produce as little as an inch of new snow, and there are also ground blizzards in which the snow that's already on the ground gets blown about by the wind and limits visibility, but very little to no new snowfall actually occurs.

My brother took our dog to her favorite place to play; she's loving the snow! She hasn't seen very much of it since she was little (we got her on 11/5/24 when she was about 5 months old). As someone who also loves the snow, her pure joy is a mood I share with her.

(Edit to add: The only AI used in that post was in the last picture; my brother used AI to alter the last picture.)

The combined Spring and Summer Photo Contest is still ongoing; I love the submissions I've seen so far! I've decided to keep it running until July 4th—which was the original start date for the summer contest before I combined the two seasons' contests into one contest—and I'll announce the winners on the 5th or 6th. (Deliberation can take me a couple-few days sometimes, LOL!) If you'd like to submit photos to the contest, please do so in the comments of the quoted post—though I'll still count any photos in the comments of this post as well, having them all under the main post makes things easier.

We have an extremely dangerous heatwave on the way this weekend and into the middle of next week with highs in the mid-to-upper 90s and heat indices between 100–110 degrees from Saturday through Monday. Tuesday and Wednesday will have highs in the upper 80s to low 90s and heat indices approaching or possibly exceeding 100 degrees.

Stay cool, stay hydrated, keep those electrolytes going with that hydration, and be aware of the symptoms of heat exhaustion and heat stroke—and keep very alert with young children as they often can't express what's going on in their bodies when they start to suffer from heat exhaustion and heat stroke. Heat exhaustion can also present with a mild but persistent headache that will worsen as it approaches the point of heat stroke.

Try to limit your outdoor activities to the early-to-mid morning and late evening hours, especially with young children.

Given the general lack of response to the spring photo contest, I've decided to change the July 4th start date for the summer contest and combine both spring and summer contests! Previous submissions in Messenger (there have been a couple) will still be valid entries for the contest!

For those new to the page or anyone who just need a refresher on how it works: You can submit your photos via comments on this post, or by sending this page a message with the photos and an additional message of "Photo Contest Entry" or "Photo contest." If you forget, though, I'll just assume it's for the photo contest, LOL! You are also more than welcome to indicate whether you want the picture(s) to be entered for the cover photo or the profile picture!

Multiple submissions are not only allowed but absolutely, 100% encouraged, and no professional skills nor expensive cameras are required!

Some of the best photos I see are from amateur photographers and/or people who just snapped a picture with their cellphone because something caught their eye! (Also, let's face it, cellphone cameras are pretty incredible these days!)

As always with these photo contests, there will be two first place winners: One for the profile picture, and one for the cover photo. Runners up and honorable mentions will also have their photos highlighted in the post announcing the winners. (Credit will of course be given to the photographers via tagging in said photo.) The announcement post will remain on the page until our Autumn photo contest so everyone who visits the page can see your beautiful pictures!

For the cover photo, landscape (wide) orientation is heavily preferred as the cover photos are so wide, but I will sometimes edit it on my computer to compensate for this— picture itself will not be altered, I'll just expand the background canvas to make it wider. For the profile picture, any orientation will do, but portrait (tall) orientation usually works the best.

Photos can be of storms, clouds, birds, animals, plants, flowers, flowerbeds, or vegetable gardens! Anything that makes one think of spring or summer is a great picture to submit!

I'm planning on starting our Autumn photo contest on September 22nd, which is the first day of Autumn this year. The contest will end on November 1st as I know a lot of people think of Halloween when it comes to Autumn, so I want to give y'all a chance to take snapshots of carved/painted pumpkins, dried gourds, etc.

I can't wait to see your submissions; they're always amazing, and I'm always excited to see what y'all come up with!

The dust storm has passed through a lot of the area already (although Jasper and Newton still have blowing dust advisories); not as bad as anticipated, but still blew up plenty of dust and pollen; we'll be gusty and dusty for a while yet, though, with the strong winds and drought conditions.

(The below images are of the storm moving through Illinois.)

~Weather Classroom: Squall Lines and Derechos~

Given the crazy winds from the squall line last night, I though I'd harken back to the August 10th, 2020 derecho (which is what both images in this post are from) that left many of us without power for several days and do crash course on squall lines and derechos!

Anyone who's been following me for a while has heard me use the term 'squall line' as well as the acronym 'QLCS' with regard to 'QLCS tornadoes.' But what is a squall line?

A squall line—properly named a quasi-linear convective system—is a long line of organized storms that can span multiple hundreds of miles. They typically form ahead of cold fronts (to the point that they were often referred to simply as "cold fronts" for a very long time) and bring with them damaging-to-severely-damaging winds, medium to very large hail, tons of lightning, heavy rainfall (not always), and sometimes QLCS/squall line tornadoes.

Squall lines will also often outrun the cold fronts that create them as the strong winds caused by a line of cold air smacking into much warmer air acts similarly to putting a car's gas pedal to the floor.

You'll often hear TV meteorologists use the term 'bow echo' when discussing weather radars; a 'bow echo' is another term for a squall line as it refers to the bow shape of the storm system, with 'echo' referring to the radar itself, as radar is an 'echo' of the radio waves that get sent into the atmosphere to give us the weather radar images. When you hear a forecaster use the terms 'bow echo' or 'squall line,' be prepared for strong winds!

Derechos are one of the strongest, longest-lived manifestations of squall lines and can be some of the fastest-moving non-tropical storms in the world with travel speeds capable of reaching 70mph, and can cause wind gusts over 100mph!

In fact, derechos have been known to cause *more* damage than hurricanes and tornadoes as sudden, powerful, straight-line winds can easily rip off roofs, blow down weaker structures, blow over trees, and blow out windows in buildings with breathtaking ease, to say nothing of the damage done to homes and vehicles by trees and large limbs landing on them. The damage can also be significantly more widespread as derechos are so big and travel so far. Derechos on average tend to travel for about 250 miles, but the 8/10/2020 derecho traveled an astonishing 770 miles in just 14 hours!

I mentioned 'QLCS tornadoes' up there, too, didn't I?

QLCS tornadoes, aka squall line tornadoes, are tornadoes that are typically short-lived and relatively weak that are created by squall lines; they also have a tendency to hop-scotch—they'll lift, then drop, then lift, then drop. While most QLCS tornadoes are, as I said, fairly weak, there have been some notable instances of EF3 and EF4 QLCS tornadoes hitting—but it's worth noting that the EF rating is less about wind speed and more about damage. A tornado with very high wind speeds that drops in the middle of nowhere can still be rated EF0, whereas a weaker tornado that drops in the middle of a city can wind up with an EF3–EF4 rating due to property damage.

A great example of QLCS tornadoes are waterspouts; there have been a lot of great videos of them over Lake Michigan over the years as squall lines blow through!

Derechos are well known for spawning multiple QLCS tornadoes, however the biggest threat with them will always be the powerful, straight-line winds.

This concludes our Weather Classroom squall line crash course! If you have any questions, do feel free to ask!
