Its A Southern Thing Snow Stays South Nice Cold Weekend
The NAM model late this afternoon shows the system spreading snow into Virginia but you can see how the northern fringe of the snow gets cut off as the dry cold high to the north holds firm. The surface low passes well southeast of the North Carolina coast. The liquid precipitation from this system could total 1 to 2 inches so some of the mountains in the Carolinas into Southwest Virginia could see a foot or more of snow from this. Major cities like Charlotte, Greensboro in North Carolina and Roanoke, Lynchburg in Southwest Virginia For us we are left with a cold dry weekend with no issues.
LONG RANGE WEATHER OUTLOOK
Looking at the teleconnections going forward it would appear that a pattern change is in order and to some degree the pattern will change a bit. We will be losing the flow of steady cold air in the east for awhile but this doesn’t necessarily mean we are headed into a blowtorch pattern. In fact the weakly positive NAO (North Atlantic Oscillation) and the strongly positive Pacific North America Index (mostly ridge in west, trough in east) compensates somewhat for the off the wall positive East Pacific Oscillation (EPO) we see late next week. Afterwards the EPO does collapse rapidly toward the neutral line which brings to a week before Christmas. Weather models will be bringing weather systems through from time to time but it doesn’t appear that anything major from a snow standpoint is in the offing for much of our area.
