Long Term Web Product

 Long range the primary focus will be on this developing low that has a potential for heavy snowfall for someone over the Midwest and East Coast. The most recent model for the GFS has shifted the low pressure center slightly farther south where the NAM and European. Currently the GFS low pressure is about 200 kilometres north of the track seen by the NAM. As seen in the image the rain/snow line (predicted by the GFS) seems to set up along the Ohio River, according to the critical thicknesses. The outlined area in red is when frontogenesis will occur Sunday afternoon and really begin to strengthen this frontal system. This will bring heavy rain/snow to southern Ohio.
