From January to August 2011
These are the similar pictures I have taken so far this year. The snow didn't really start melting, until the end of March by April 15 it was gone. Then it really got cold it stayed below average until middle of June. July went off the charts hot with dew points in the upper 70's and 80. We set a record for the highest dew point ever at 82 degrees. Here in Minnesota the dew points in the summer, on average we have 13 days of dew points in the 60's to low 70's, this year we've had 19 days and it's not even the dog days of summer. A few times each year it will get too hot to rain, that has only happened once so far meaning it's been a very wet. In the winter dew points are 30's and 40's. The yearly average dew point is in the high 40's. Like summer in winter it gets too cold to snow, that's when you can see ice crystals in the air that don't seem to hit the ground like dew would. How this happens here in both summer and winter is when the upper and surface temperature is around the same. The reasons the ground frost here can go deeper then 4 feet down, when we don't have enough snow cover to insulate the ground until mid November or December. Now if your still reading this you have more information about Minnesota climate then some of the people who live here have.
This year within 48 hours we went from a high of 58 degrees with a dew point of 43, to a high of 83 degrees and the dew point in the mid 70's. People like to say "It's not the heat it's the humidity!" The higher the dew point temperature is, the harder it makes it to breath.
