Weather models are focusing on weak overrunning for Saturday. Earlier this week weather models were a bit more robust with this system but they seem to have backed off from a 1-3/2-4 inch snow. Only the NAM model at this point suggests that it could be along those lines. Little systems such as this always require some monitoring. There is not a lot of support aloft. The system is weak at all levels. Basically this is a weak wave that develops on the boundary to the south between cold air over us and to our north and warm air to the south. The cold high to the north acts as a suppressant and forces dry air further south and that seems to be the case here.
