Snow Continuing for the Northern Plains and Great Lakes through Early Thursday Morning
The area of low pressure that is currently bringing snow to the Northern Plains and Upper Midwest will continue to move across the region through early Thursday morning. Moderate to heavy snowfall will continue to the north and west of the low as temperatures fall below freezing. Snow accumulations will range 3-6 inches with locally higher amounts in excess of 8 inches to the north of the low. Near the center of the low where temperatures will be near freezing, a wintry mix will be possible. This will limit snow accumulations, but some light freezing rain may develop. Ice accumulations will generally be less than 0.10 inch.

Thunderstorms for Southern New Mexico and West Texas on Thursday
An area of low pressure is forecast to develop near the Four Corners region on Thursday. In response to the low, southeasterly winds will increase available moisture with a dry line developing over central New Mexico. With the increased moisture ahead of the dry line, instability is forecast to increase during the afternoon due to strong surface heating. This instability will result in the potential for a few strong to severe thunderstorms to develop by late afternoon. Strong winds and large hail will be the primary hazards with these storms.

Potential for Thunderstorms Friday across West Texas and Southeastern New Mexico
As the surface low described above continues to move eastward, increased moisture associated with southerly flow is forecast on Friday. As a result, a dry line is forecast to develop with instability building to the east of the dry line during the afternoon hours. Instability should be sufficient for the development of thunderstorms during the afternoon. Strong winds and large hail will be the primary hazards with these storms.
