Why So Much Wind?

March is known as the windy month, but, now it is April, so why is it still so windy? Well, vigorous weather systems are still common in early to mid spring, as the battle of the changing seasons still manifests itself on the weather map. The battle between the warmth developing over the south trying to move north, and the still cold air in Canada trying to move south, results in huge temperature contrasts, which leads to huge pressure differences, which results in the very rapid movement of air, better known as very strong winds. On Tuesday, 4/01/08 we had a strong and very mild S-SW wind, and on Wednesday, 4/2/08, we have a very strong and much cooler NW wind, as a cold front moved through Tuesday night and ushered in the much cooler air mass.
