Temperatures are expected to approach freezing or just above this afternoon thanks to a warm southwesterly breeze. The featured chart is a wind rose displaying the frequency of wind speed and direction during times of having the temperature above freezing. At first inspection, the high frequencies from the northwest may seem odd, but this is a favored direction for "chinook" style winds blowing down the Rocky Mountains and into Iowa. The downward motion of this air heats it and creates a warm transport into the state.
