Snowfall Totals by Location

These tables show the snowfall forecast for individual locations. The tables provide the same information as the maps on this web page, just shown in a different way. The "Exceedance" option shows the chance that snow will exceed a certain threshold. The "Range" option shows the likelihood of snowfall being within a certain range. All of these values are valid for the same time period as depicted on the graphics.

Low Tracks Graphic The graphic depicts the forecast location of significant surface lows impacting the 48 contiguous United States in 12 hour increments out to 72 hours into the future. The low position and track forecast by NCEP WPC meteorologist is in white. Each low position is accompanied by a lead time (Eastern Time). The circles around each low represents a 75% probability the observed low will be located with the circle. Note: The probability is derived using previous season's verification data. For reference, existing surface lows are depicted with a red marker without yellow circles. Precipitation Onset Most likely time of winter precipitation onset (snow, sleet, freezing rain). Rain is not included here. This information is provided when we issue a Warning or Advisory for expected snow or ice accumulation; typically six to 24 hours in advance. Times are only given for places that are under a Warning or Advisory. They will be blank in areas outside Warnings or Advisories. Reported As snow and/or ice reports come into the NWS (you can email reports to bou.webmaster@noaa.gov or Tweet to @NWSBoulder), we will pass them on here. With the map linked here, and the supporting reports below it, you can keep tabs on how much has fallen.
