You can check snow accumulations from our latest storm as they are posted by the National Weather Service. Hover over a location on their snow map site to see the snow total and the time of observation.

You might want to move the slider at the top of their map to 36 hours or 48 hours to include snow reports that came in early on Thursday.

Here’s a snapshot of the National Weather Service snow map as of 8:40 a .m. Friday:
