This explains a lot
Posted:

The featured chart is a wind rose for observations reported so far this
month from the Ames Airport. A wind rose nicely shows the summarized
combination of wind direction and wind speed. The longer the bar is,
the more common the wind has been from that direction. The chart shows
the lack of winds from the SSE around to the west. These winds would
be bringing warmer air into the state and make things feel more like
spring. Our dominant directions have been ENE and NW, which is a cold
and wet combination.
