Quite a bit when I was stationed out west. Like someone said above, beautiful when enjoyed from indoors with a nice fire going. Scary when stuck driving in one.

I also got to experience cool ground blizzards driving back and forth to work. Those are really fascinating. Snow blown along the ground so thick you can't see the road right in front of you. Yet look out the window and the sky is clear. Actually been in some where I couldn't see my feet, but sun was shining and blue skies. From the waist down was blowing snow, but nothing hardly above that.

I think I experienced one in February 2015. It was a couple days before a big snowstorm and we got about 1/2" (1 cm) in 20 or 30 minutes, with it having been sunny most of the rest of the day. It was heavy snow that significantly reduced visibility, but we had a snow day that day anyway so it wasn't really a problem.

Check out this timelapse from NYC... nice!!!

For those of you who never experienced it, before it happens sometimes its a sunny day and you see a wall of cloud in the distant... then it arrives and visibility drops to under 1/2 mile and it basically looks like fog from certain angles above, but at the surface its like a blizzard with wind gusts too. Its very cool to experience. High ratio snows too since its happening in very cold air.

They produce 1-2"/hr rates of snow depending the width or length of time.

I recently experienced one in Forest Lakes, AZ on Thanksgiving night. Snow was so heavy that I couldn't see more than a car length ahead with the fog lights on and wipers on full blast!

The road was closed later that evening

That looks like it was more convective bands from a storm system and trough digging down. https://mesonet.agron.iastate.edu/wx...e=201911280618

the well-advertised storm system is generally on track,
with perhaps the main changes being a slightly slower timing of
frontal progression into Arizona, and an uptick in the potential
for precipitation across southeast California. Still expecting
precipitation to develop across both parts of southeast
California, and south-central Arizona by Thursday morning. In
fact, some CAM guidance shows isolated showers developing later
tonight east of Phoenix. This would be associated with a broad
low-level warm advection regime advecting the aforementioned
moisture plume northward. There is some concern for localized
heavier rates
into southern Gila County overnight tonight, but
confidence is still low in this potential.



Still expecting more significant precipitation chances to develop
on Thursday, and will likely bring travel impacts, especially to
higher elevation areas. The amount of shower activity preceding
the front is still unclear, but at least a decent number of
ensemble members showing scattered areas of light precipitation,
with better chances across terrain-favored areas. Meanwhile, most
of the heavy precipitation potential will accompany the strong
cold front moving eastward. HREF ensemble guidance shows marginal
destabilization occurring near the Colorado River during the
afternoon, which should aid in more intense low-topped convection
developing along the cold front. Wind profiles are very favorable
for producing strong wind gusts with this convection.
Additionally, a 50-60 kt southerly low-level jet will be
positioned across southern Arizona, and will further enhance wind
gust potential, even away from any convective bands.

BTW -- It's a Federal Alert. So they send the Snow Squall Warning on your phone. I didn't know this and thought it was an Amber alert when it was sent last week.


A Snow Squall Warning itself is still a relatively new concept for the NWS, but the push alert is brand new this week, and it comes from the Federal Communications Commission.

The FCC's WEA System issues warnings like Amber and Presidential alerts, and several weather warnings, mostly focusing on immediate time sensitive dangers. This includes Tornado Warnings and Snow Squall Warnings, but not Winter Storm Warnings, which have much more notice.

Unlike a winter storm, a snow squall is a narrow heavy band of snow that moves in quickly with very low visibility, like a short-lived blizzard, a hazard that most affects travelers.

I voted yes but it wasn’t as intense as the snow squalls above. It was sometime in the late 90s or early 00s and I was visiting a local shopping centre - it was dry and there was no snow on the ground when we got there. By the time we left it started snowing intensely out of nowhere, with the snow virtually falling horizontally in a gusty wind. It turned white everywhere quickly and my face was in pain because it was being pelted with snow. Kids leaving with their parents were crying.

Can’t remember what year it was exactly though. I was in high school.

For those of you who never experienced it, this is what Graupel is. I just had a squall come through but it wasn't snow. It wasn't sleet either. It was Graupel. It's pellets that look like sleet but soft like snow.

Cool, I didn't know it had a special name, I've always just thought of it as dry snow or snow pellets as opposed to snowflakes.
