GSP is discounting the NAM’s thermal profiles: “The NAM is substantially warmer with temps aloft than any of the global models we have at our disposal. For now the NAM profiles are being discounted and not used in the fcst process, not only due to the consensus in the other guidance, but to help maintain better forecast continuity” Also, they are thinking the mountains are going to see a larger percentage of the precip fall as sleet: “"Snow" totals have declined by a few inches over the northern GA/SC zones and in the more western NC mtns, as more of the QPF is now expected to fall as sleet.”
