It has been stressed over and over that this is a very stormy time of year, so what we are experiencing now is not unusual. A bit crazy maybe, but definitely not unusual. The stormy pattern is in response to the growing warmth across the South and the residual cold that still exists across the north. This forces larger temperature gradients, which are reflected in larger differences in air pressure. The pressure gradient causes the air to move, and this is how storms get born.

The latest in a series of big storms will track right across the heart of the nation this weekend, causing blizzard conditions from eastern Wyoming into Nebraska and southern South Dakota. Next week, this same storm will have a huge bearing on the weather in the Eastern part of the country.
