PLEASE NOTE: The winter probablistic graphics have been discountinued until fall of 2017. The purpose of these experimental probabilistic snowfall products is to provide customers and partners a range of snowfall possibilities, in complement to existing NWS deterministic snowfall graphics, to better communicate forecast uncertainties during winter weather events. For more information visit this project's Product/Service Description Document, and please provide us your feedback. here.

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.

Reported

As snow and/or ice reports come into the NWS (you can send us reports at https://www.weather.gov/bou/stormreport 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.
