It's not even mid-October and we had snow!! Does this have to do with global warming?

Here is something I noticed - maybe only a coincidence, but maybe a physical reason for it involving the overall flow pattern of the Northern Hemisphere:
Last time an El Niño of the charateristic type formed - large sea surface temperature anomolies extending from SW South America across much of the equatorial Pacific as shown below:
http://www.cpc.ncep.noaa.gov/products/analysis_monitoring/enso_update/sstanim.shtml
a strong Low developed during October over the central Plains and inundated the part of the Rockies & central Plains with snow - some of their largest totals occurring. That was October 1997:

http://www.cnn.com/WEATHER/9710/26/plains.blizzard
The Low causing the recent cold outbreak was a larger and strong one over the Plains E of the Rockies, but much further N - over south central Canada. The circulation around the strong Low to the NW-N (plus strong NNW winds around 600-500 mb) simply brought cold air over the Great Lakes region and E.
Such a Low during October may be something which tends to occur during an El Niño - how it affects the large scale flow in the transition from summer to winter.
Hoepfully someone will find this interesting & helpful.

Precipition occurs when the air temperature becomeslower than the dew point. The atmosphere can no longer maintain water vapor at that concentration and therefore the water condences into dropplets. Snow forms when the dew point is below the freezing point of water. The freezing point is also affected by pressure in addition to air temperature. The water vapor crystallizes to form a solid and actually by passess the liquid stage. Water is a unique substances in that it has a triple-point where by at a particular pressure and temperature it can actually exist as a solid, liquid, and vapor at the same time.

I even have lived in Michigan for sixty two years. besides the reality that we in lots of cases get out first snows in November, it quite is not even formally wintry climate here yet. lots of the time I even have lived here we've had a white Christmas and we do commonly get snow in December, yet not by utilising the 1st inevitably. Ice soften will result US climate, even though it quite is confusing to coach that GW has been the wrongdoer for optimistic for the severe climate we've experienced this 3 hundred and sixty 5 days.

This map shows how much snow was on the ground Friday night at midnight. Most of it fell in Ontario, but some in Manitoba, Minnisota and Wisconsin as well. Check it out.

well it might have rained but a cold front is coming in from Canada...have you noticed that it has been quite windy? The wind blows in the cold air which is why it is snow instead of rain, we had sleet here two. *a mix of rain and snow* (i live in minnesota(

Precipitation and cold temperature equal snow.
