A swath of heavy snow, from the Colorado Front Range to the Great Lakes region, is not the result of a potent winter storm. Rather, this bowl-shaped band of snow, that dips across Texas and up through the Midwest, is due to a dome of Arctic high pressure that is sinking southward through the Heartland.
As the cold air is forced upward along the Front Range or encounters warm, moist air in the Southern Plains and Midwest, heavy snow is produced. Along the east rim of this bowl, a band of ice (sleet or freezing rain) precedes the snow.
Here in central Missouri, we received about 8 inches of snow. As the high pressure dome gradually drifts eastward, the bowl's southern edge will pass through our region, bringing flurries and possible further bouts of snow overnight.
