Long Range

Alex Coffman & Matthew Valentin Dellagado

Long Range Summary: After the small disturbance that passes through the region on Saturday, we will see high pressure settle into the area on Sunday and for the beginning of next week. This high pressure will usher in colder, northwesterly winds, and more temperatures at or near zero is possible. As this low passes to the east, the 12Z GFS indicates that some warm air advection will be taking place over Indiana. According to this model, however, and based on the zonal flow that we are in, we will likely not be seeing any sort of warm air advection occur for any long, as cold air will crash back into the area with the next storm.

Around -0.25 K/hr cold air advection at GFS 18Z mon
