I was looking into the forcing behind the precipitation event that is set to happen Thursday afternoon.  During the evening and night hours of Wednesday, there is a large amount of temperature advection, so I made a parallelogram of the northeast to central region of Indiana to obtain a value for geostrophic temperature advection.  The equation I used was (g/f)*((deltaT * deltaZ) / (deltaX * deltaY).  I found the geostrophic temperature advection for this region to be 7.2 C per day.  The image below shows a map of the region, where I performed my calculations and values are similar to each other.  The image below has values 8 C per day in that general area.
