Snow May Produce Poor Travel Conditions in the North-Central U.S. and East Coast

A strong cold front sweeping across the Northern Plains may bring snow showers and snow squalls from eastern Montana to north-central Nebraska, with blizzard conditions possible in eastern North Dakota and northwestern Montana. Heavy snow is expected to persist downwind of the Great Lakes. Snow showers will spread up the East Coast across the Mid-Atlantic and Northeast coasts. Read More >

Measuring and Reporting Snow to the National Weather Service

The National Weather Service needs your help!  During snow storms, your snow depth measurement, especially if you live in a rural area, is valuable information for determining the impact of the event and accuracy of our forecasts.  When it snows, we encourage you to find a simple yard stick and take snow depth measurements every 3 to 6 hours -- more often if conditions are rapidly changing.  Please report your snow depth (in inches) using our Storm Report Form.  Your report will be immediately sent to and viewed by a NWS forecaster.

Taking accurate snow observations is very important. Please click the following slides for a short primer on how to correctly measure snow depth.
