Minimum Potential Accumulation

Expect at least this much. This is what we see as the least amount of snow the storm can produce.

This information is for advance planning ahead of the storm. It is provided out as far as three days. However, when the snow starts to fall, this will be discontinued to focus on the forecast snow amount.
 

Most Likely Snow Accumulation

Represents our official snow forecast in inches within the next one to three days. The snowfall amounts are provided in point (single number) and ranges (1-2", 2-4", etc.). You can toggle between the two by hovering over the "Point" and "Range" text above the image. The point amount is our forecast but the range for the "most likely" represents the forecast uncertainty in predefined ranges.

Maximum Potential Accumulation

What you should be prepared for. This is what we see as the storm's maximum potential snowfall accumulation.

This information is for advance planning ahead of the storm. It is provided out as far as three days. However, when the snow starts to fall, this will be discontinued to focus on the forecast snow amount.
