As shown in the figure below, we are currently experiencing a cold front with cold advection that followed a low pressure which brought precipitation. Our winds are out of the north, with temperatures at the 850 mb height below freezing throughout the state of Indiana.
The figure below was taken 48 hours after the one above. There is a high pressure system in the southern portion of the United States. This will cause a warm up for Indiana due to slight warm air advection. In 48 hours, the temperatures in the 850 mb level will rise anywhere from 8-12 degrees C throughout Indiana. The high pressure will lead to sunny and clear skies throughout the state, for several days.
