Average daily temperatures rise 10 degrees F during the month in many eastern and central cities with the changes accelerating late in the month. The rate of warming will peak in April in most areas. Because the sun warms the earth's surface faster than the air above, the air becomes increasingly unstable. The instability of the air causes deep atmospheric turbulence and mixing which helps bring stronger wind gusts down to the surface from aloft. The combination of deep storms and unstable air makes March for many locations the windiest month of the year.
Storms continue to move inland from the Gulf of Alaska into western Canada.
Other Pacific storms come inland into Oregon and Washington state and then reform east of the Rockies in Colorado or over the Texas or Oklahoma panhandles and head towards the Great Lakes or Ohio Valley. These storms can be very wet and produce heavy flooding rains and snows. Blizzard conditions can prevail to the northwest of the storm track. The more southerly Pacific storm track into California becomes less frequent. The Gulf of Mexico remains important as either a genesis region for storms or as an energy and moisture source for storms tracking further north.
