The coldest temperatures of the season were experienced Wednesday morning over areas that had clear skies overnight. Other locations in the state with clouds were many degrees warmer. The featured chart displays the combined time series of all airport weather stations in the state. When the site was reporting clear sky conditions the dot is blue and for all other sky conditions the dot is grey. A remarkable and pretty contrast is shown by the chart with the coldest areas being clear and warming quickly with the rising sun during the morning hours. The impact of clouds during the daytime can be seen as well to suppress heating by reflecting the sun's energy prior to it arriving at the Earth's surface.
