StormWatch Today: Thursday, 12/23
Three areas across the U.S. have the attention of the ImpactWeather StormWatch team today:
Moderate Risk: Winter Storm. A strong Pacific storm system will continue pushing eastward through the southern Rocky Mountains today. Additional snowfall amounts of 3-6 inches will be possible across the elevated terrain of the Four Corners region, with some higher amounts expected in western Colorado. Rainfall amounts up to one inch will be possible across southern Arizona.
Slight Risk: Heavy Snow. A developing storm system over the Plains will spread deep moisture across portions of the Northern Plains and Midwest today and Friday allowing for the risk of light to moderate snow accumulations. Snowfall today this morning will begin across the Dakotas then spread southeastward into southern Minnesota and northern Iowa later today, then into central Iowa, northern Missouri, and northern Illinois tomorrow. The heaviest snow accumulations are expected to fall from northern South Dakota through central Iowa, where up to 4-8 inches, isolated 12 inches are possible.
Slight Risk: Heavy Snow. A surface low pressure area moving through the southeast United States will bring the possibility of accumulating snowfall on Saturday to portions of the southern Appalachians. The exact snowfall amounts will depend on the track of the surface low, but it appears that 1-3 inches will be possible as far south as northeast Georgia and northwest South Carolina. High amounts are likely over the elevated terrain of the Appalachians.
