The latest cycle of the 12z model set has led to a high and very large uncertainty for forecasting SE MA and RI weather for Monday night into Tuesday afternoon.  The cycle was spilt down the middle, one side shows a potential major impact of snow and wind for the area then, but the other set as the secondary low taking off to far east and southeast and has a very little impact on the area for snow.  Right now, there is a less than 40% forecast confidence in any direction.  This is very poor for this range.  Update on the 18z model cycle.
