How can you tell when a cold front is approaching?

Answer 1

The best way, of course, is to check your favorite source for local weather.

There are some ways to guess that it'll snow, but by the time you do it will almost be happening, and you could save yourself time by checking the above.

Before a storm, typically you get get high cirrus that gradually lower - it may start with mid-level altostratus or altocumulus that lower and eventually turn into a grey overcast. It will often warm up closer to freezing if it has recently been warm, for dynamic reasons I won't get into. Actually, people who live off the land such as natives of the Arctic, are quite good at predicting the onset of storms.

Some people claim there is a smell to the air. I don't know how much truth there is to that, or why it would be true.

Answer 2

Look at the weather forecast. Really, that's the best thing to do these days when there is so much data out there, especially from the upper atmosphere that is input into advanced computer models. Storms can be forecast if you have the tools so much better than just looking at the sky. If for some reason this is not possible, snow storms come in the same way most others do - high cirrus a day or two in advance, then altostratus (midlevel clouds) which lower to nimbus and begin to darken and precipitate.

Answer 3

• As warm air rises, it expands and cools. The rising air soon reaches the dew point, the temperature at which the water vapor in the air condenses into droplets of water or form tiny ice crystals.

Answer 4

Answer 6

A flurry is usually under 45.f a snow on the ground is 32.f a heavy snow is under 20.f but it has to be cloudy and it has to have a chance of rain on the forecast

Answer 7

because you see big foot land coming toward us so we know there's a snowstorm coming too.
