WeatherWhys for April 29,2015 from accuweather.com

The intensity of solar radiation entering the Northern Hemisphere is constantly changing. In winter, the sun stays low in the sky, and the rays are weak. In spring, the noontime sun is much higher in the sky, and the energy imparted to the ground is much more concentrated. That leads to greater surface heating.
