I hope you're joking. There's no such thing, that's an old folklore type legend.



I don't even want rain. I'm looking forward to the next deought, where it doesn't rain for 3 or 4 weeks.

How much snow??? That answer can be somewhat 'foggy' or one might say 'snowy' even.
I am glad I keep my tin foil cap handy for these type of questions.
Straighten it out a bit to get back into the shape of a cap.....ah that's better.
Placing gently on head, adjust the 'z' axis a bit.
Concentrating on weather.....winter weather, spring and summer I must tune you out...boo-hoo.
Ah there is the winter scope coming into view....
Hold on have to add the 2nd pair of socks and mittens...toe jams and fingers are getting cold.....
Hmmmm......a-ha......oh not that!!!! Wait for it........

2.8576 inches or 7.2583 cm if you like.

That's it, taking the tin foil hat off, socks and mittens and putting away for the next question on snow.

May your shovels be ready,
May your salt be salty,
and may you enjoy the snowfall as a kid again!

No it's not - especially on pavement/roads.

Ever wonder why bridges freeze first?

Yep, that's the way we roll!

Makes absolutely zero difference. I've seen several inches of snow stuck just fine in April after many 70+ days. Folklore, plain and simple. Hogwash.

Nope, I don't wonder why bridges freeze first. Science isn't confusing.

Even Greg Fischer went on about this myth a few years ago saying the old legend of "ground too warm" was hogwash. For once he was spot on! ; )

Snow aside, Weather Channel currently predicting a low of 5º Sunday night. Wouldn't surprise me one bit if school gets at least delayed even just for that.

Definitely, if we get any kind of precip, it will be frozen solid on Monday morning so start planning WEATHER DAY activities with the kids ugh.

Bridge freeze first because there is cold over and under the relatively thin layer of pavement, has nothing to do with overall ground temperature or how warm it's been.

If it's cold enough to snow, and it comes down fast enough, it WILL stick, even though it's 60 freaking degrees today.

Let the brining begin!

Yes but the colder the ground, the quicker it will stick and accumulate. When the ground, especially pavement is on the warmer side, it takes much heavier/steadier snow for sticking to occur.

http://www.theweatherprediction.com/habyhints2/452/

"4. If the ground surface temperature is above freezing, sleet and snow will melt as it reaches the surface. An exception to this is when heavy sleet or snow falls and the accumulation rate exceeds the melting rate. If sleet or snow are seen falling, even if the precipitation melts when it reaches the surface, it will still be reported as sleet or snow."

Correct. It's called thermal mass. If it's been warm or sunny roads will retain heat. Snow will stick to grass first and eventually the road when it gets cool enough. Bridges being open on top and bottom see the cooling affect from the air temp prior to most roads.

We almost always have a layer of ice beneath the snow in this area due to the melting on the road that happens in the beginning of the snow fall.
