Thundersleet in Duncanville

Help us folks stuck at 34F out... This thread needs more pictures!

Good thing that's not all freezing rain like RGEM had or he wouldn't be able to do that. Much easier to travel/get traction on. Be safe everyone. Things really begin to ramp up tonight into Wednesday.

The airports are a mess. I was supposed to fly to SF this morning and was rescheduled for this afternoon. I can't get out of my driveway.

Edit: Advisory 047. Average delay at DFW now 5 hours, 1 min.

Just had a huge flash and then my dog about peed himself with the ground shaking thunder…coming down in downtown Dallas.

Latest Wrf temp forecast keeping a good chunk of North Texas between 26-28F thru Thursday morning…seems to be the most plausible scenario given current state of ground cover now.

Thundersleet for the 2nd day in a row

Back edge starting to move through so that’s about it for this round.

[Texas Snow]

Steve McCauley explains the snow with warm higher level temps

Okay...think I may have found the answer to the "how can it be snowing" question...and it is a bit embarrassing!

You know, we are taught how to determine what type of precipitation will be observed at the surface with any given atmospheric setup, and you learn a certain set of procedures that - in the vast majority of cases - leads you to the correct answer. And in so doing, you totally ignore the "exception" to the rule which occurs so infrequently, you don't even bother including it in your decision making process.

Well, I totally ignored the exception to the rule. Shame on me, minus 10 on the quiz.

You see, usually, you need temperatures down to around 14°F to form your typical snowflake in the atmosphere, and for us, that usually happens thousands of feet above the ground. But today, thousands of feet above the ground, the temperatures are well above freezing across north Texas.

But there is an unusual "snowflake" that looks like a needle instead of your typical hexagonal ice crystal. These needles only require temperatures of 23°F inside the cloud to form, and as you can see in this pic, that is precisely the kind of snowflakes we had. They look like little white elongated hairs.

So, we didn't have to go thousands of feet into the air to find our snow factory. It was only a few hundred feet above the ground.

How embarrassing, and shame on me for forgetting this simple little fact of cloud microphysics.

But still, the real trick is knowing WHEN to forecast such an event, because this doesn't happen every time a cloud drops to 23°F !

Prefer sleet.

This whole event has me questioning algorithms on weather map sites. Even when it's sleeting they are showing freezing rain. I know raw model output doesn't discern colors, only raw data.

We have snow mixed with sleet here in Dallas.

Heck, even the WPC is clueless. They said it was freezing rain just a bit ago. And they are experts trained in this. So much we don’t know.

I don't think my School will be in person until at least Friday, the roads are completely sleet covered.

Easily 0.5-1"+ of sleet has fallen across the metroplex.

0.33" qpf.

No word yet on schools for tomorrow but it is only a matter of time. Parents should prepare for another kids day off Wednesday.

Well, mine (I'm in HS) are prepared to be off until at least Friday.

They won't go back until Friday.

So do we think tonight/tomorrow is going to be mostly sleet or freezing rain for DFW? Some local mets are still leaning to the latter despite the temp “bust” thus far.

Agree 100%.

no icy roads on my commute into north SA from the hill country this morning...fine with me

NAM maps has been good so far on p-types. Sleet but transitioning to freezing rain. So after a nice sleet event, glaze it over with a sheet of ice.
