North American Mesoscale predicts winter Storm in Minnesota arriving Monday night

The North American Mesoscale (NAM) prediction model of the National Oceanic and Atmospheric Administration depicts the anticipated precipitation pattern from Monday morning through Tuesday evening.

Snow, rain, and freezing rain are expected to fall on the upper Midwest Monday and Tuesday.

Monday afternoon and evening into Tuesday will mostly see snow. South-central and southeastern Minnesota and parts of western Wisconsin could see several hours of freezing rain before transitioning to a wintry mix and eventually all snow.


Some computer models predict one inch of rain in many regions on Monday through Tuesday night. This includes rainfall as well as the water content of the snow. That would be higher than our normal monthly precipitation total for January.

The strongest snowfall is forecast in southern Minnesota, where many places will experience double-digit accumulations during the next two days. Snow accumulations of 6 inches or more are forecast in central Minnesota, the metro area's northern outskirts, and northwestern Wisconsin.

Southern Minnesota and parts of southwestern Wisconsin will have the greatest possibility of frozen accumulations from freezing rain.

Winter Weather Advisory is in force for parts of Southwest, South Central, and Eastern Nebraska. The panhandle and northern Nebraska appear to have received the most snowfall. The most ice buildup appears to be in central and northeastern Nebraska. Travel will most certainly become extremely difficult or impossible in several areas. Significant power outages and tree damage may occur, particularly in regions with the most ice buildup. Surface temperatures and the storm system's trajectory will significantly influence the kind and amount of precipitation in the area.

Winter storm warnings have been issued for parts of central and southern Minnesota, including the Twin Cities metro region.

FAQs:

1. What exactly is Nam in meteorology?
   The North American Mesoscale Forecast System (NAM) is one of the key weather forecasting models used by the National Centers for Environmental Prediction (NCEP).
2. Who has the most precise weather forecast?
   The ECMWF is often regarded as the most accurate global model, with the GFS from the United States trailing somewhat behind.
