Yes,it is a fact that it is cold at the poles where it practically snows all the time,but in the US temperatures don't drop that low.\nPeople say that-"it is too cold to snow" , because in this case the temperature is too low(for our geographical positioning) to "hold" water in the air which prevents it from snowing.\nHope that my answer has been useful!

could be snow, could be +10 or +20 degrees, could be a little bit of rain.  One never knows in the spring time!

It rains when the air can no longer hold onto the moisture in an evaporated, cloud form.  It can be cold and rainy, mild and rainy, or hot, muggy and rainy.  \n\nMoisture moves on the air currents. During winter, rain usually comes when it is cold because the air currents bring COLD air from the far north (remember the "jet stream" they talk about on the news?)  But when air currents from the tropics move overhead, temperatures are warmer because it isn't cold in the tropics. And tropical air often brings a huge amount of rain (think hurricanes).\n\nDuring summer, if there is moisture in the air, a lot of moisture, it condenses and turns into liquid form (rain) when temperatures and moisture content of the clouds reaches the right combination.

Pressure changes affect the wind.  Temperature change determines whether it will rain or snow.

You can thank the upper-air weather pattern for all the rain. I'm a storm chaser from Texas and these blocked patterns (upper ridge over the Rockies and upper trough over the Atlantic states) spell disaster for us looking for tornadoes across Texas, Oklahoma, and Kansas. We constantly stay dry, and you guys constantly stay wet. Until the pattern changes to a more traditional West to East flow and can kick these blocked troughs / ridges out of here, we're in for more of the same.

Sorry you have had so much grief with the cold weather.\n\nWell, winter usually does bring cold weather and not knowing where you are, would give us a clue as to why, but I bet forecasters did give a hint that it might be that way.

Cold and dry, which is a good thing, since I live in Wyoming.  Very cold and dry up here.  Hot humid days kill me.

Well, I hate the cold, and I hate driving on slippery roads, so unless I can just stay home, I prefer rain.  Snow is pretty to look at, but again, if I can stay home.

The warm air pushes over the denser cold air and itself cools  - hence the snow. As the cold air gets replaced by the warmer air, we experience  the rain.

It all depends upon the layers of temparature in the atmosphere.  If an upper layer where the precipitation originates is below freezing then it can snow even if it is above freezing at ground level.  Reverse those temperatures and you get freezing rain.

Don't be silly !!!!!  If only....\n\nI read somewhere it is meant to be rainy & windy\n\nI would love it to snow, fingers cross ..

I'd love to send you some of our rain to help cool things off.  It's about 70 degrees Farhenheit here on the Atlantic coast of Canada.  We're nowhere near a heat wave.  I'm hoping we'll at least break into the normal summer temperatures.  Without the rain, of course.  But at least we aren't getting hammered like the people on the Eastern seabord of your lovely country.

As the water vapor cools along with the air, it begins to go into a liquid state and will collect on anything it can, usually dust particles in the air. From there, it depends on the amount of water and the air temperature whether you will get dew, rain or snow.

It depends on where you live. Many parts of the world get lots of rain and clouds in the summertime. \n\nYou may live in a mediterranean climate, where the local weather pattern is rainy winters and dry summers. The reasons for this vary from locale to locale. In the town that I'm writing from, there's a mountain that blocks the cool, moist winds that blow most of the year. We can get a lot of rain coming from the other direction, but the winds only blow that way in wintertime. \n\nTo know exactly why you have those weather conditions, I would need to know where you live.

The meteorologists say the IT (the weather) is going to be warm, they don't presume to dictate how one will react to that situation.  Not everyone will be warm, but the weather may be.
