What is that wintry precipitation??

This is the weirdest precipitation. It consists of tiny little white balls that melt pretty much on contact but are very cold. They look like Styrofoam pellets. Is this miniature hail? (Very elusive; hard to photograph. Ignore the dirty car in the background and look at the bottom of the window. I took the picture from inside my car looking at the stuff on the outside ledge of my car with the dirty car in the parking spot next to me.)

I really wanted to know what it was so I went to the ultimate source: Facebook. Here's the ensuing conversation:

From a friend in Colorado: We get those here too. I know, they are weird.
From my cousin in Florida: Looks like hail to me?
I reply: It's softer than hail. It's like a tiny snow ball. 
From a friend here in Farmington: Sleet
I reply: It doesn't look like any sleet I've ever seen before. Too dry...sleet is icier and wetter in my experience. Now I'm going to have to look up the science of sleet to see how one word can encapsulate two such different things!
From a friend in Texas: This is why Scandinavian countries have a dozen different words for all the different types of snow.
Tomorrow, I leave for Galveston with the Butterfly Friends. One of them replies: Galveston is going to feel so good!   
Next comes a URL from a Farmington friend: The pic isn't good, but from your description and photo - and they aren't that unusual here. smile emoticon https://www.washingtonpost.com/.../graupel-the-wintry.../ 

From that website:
When you think of wintry precipitation, you probably think of snow first. Then sleet, and maybe freezing rain. But it’s likely that the word “graupel” doesn’t come to mind.

Graupel, which is a kind of hybrid frozen precipitation, is sometimes referred to as “snow pellets.” The National Weather Service defines graupel as small pellets of ice created when super-cooled water droplets coat, or rime, a snowflake.

Graupel pellets are cloudy or white — not clear like sleet — and often are mistaken for small hail. The most critical necessity for the formation of graupel is extremely cold air at the cloud level. This creates the super-cooled water (liquid water that exists below the freezing point), which adheres to the snowflakes.

How to know if ice is safe

As a Texan, I'm used to warnings, procedures, and tips about safety when it comes to tornadoes. After all, Texas has more tornadoes strike than any other state. The injuries and damage are devastating and even more so when you realize that most of the time, there was nothing that could be done to prevent it. And then there are always those that don't heed the warnings and do foolish things and suffer their own consequences. And if you're not from Texas (or any other tornado state), this all seems rather foreign. Today, the shoe was on the other foot as I read an article in this month's Franklin Focus called "Ice: Is It Safe?" The article opens with "Each year about this time, the Maine Warden Service urges us to use extreme caution before venturing out onto any ice that may be covering Maine's waterways." Those wardens must be as frustrated as Texas Department of Public Safety officials who get the message out year after year only to have a few who ignore the information. Alas. Humans will be human.

Meanwhile, did you know there was such a thing as an Ice Strength Table? Check it out! The directions say "Never guess the thickness of the ice. Check it! Check the ice in several different places using an auger or some other means to make a test hole and determine the thickness. Make several, beginning at the shore, and continuing as you go out. Check the ice with a partner so if something does happen, someone is there to help you. If you are doing it alone, wear a life jacket."

Here's where it should start to be obvious, even if you aren't from Maine or didn't grow up in places that have ice over bodies of water: "If ice at the shoreline is cracked or squishy, stay off!" I also liked this piece of advice: "Parents should alert children of unsafe ice in their area, and make sure that they stay off the ice. If they insist on using their new skates, suggest an indoor skating rink."

ICE STRENGTH TABLE

Modified from the Northeast Logger Magazine, 1968.

Inches of Ice	Permissible Load for Clear Blue Ice
1	Unsafe for humans
2	One person on foot
3	Group in a single file
4	Snowmobiles & ATV’s
7	Passenger car (2 tons)
8	Light truck (2.5 tons)

Note: The above table is for clear blue ice on lakes and ponds.

Here's some interesting math: "Reduce the strength values by 15% for clear blue river ice." So 2" is safe for 85% of one person on foot? Maybe it's 2.33" to be safe for one person on foot?

And I'm not sure what this means, but I'm fascinated: "Slush ice is only 50%  the strength of blue ice."

There's no mention of what to do when the ice is covered by snow.

It turns out, I don't really have to worry about any of this. My motto is: "Stay off the ice unless ice fishing and then trust the people you're with to know if it's safe." And only go ice fishing with someone who does it all the time without consuming adult beverages.
