Storm Impact Zones
Areas along and north of I-70 are projected to receive the heaviest snowfall, while regions further south—from Sullivan to Red Bud and Mount Vernon—face the prospect of a major ice storm. The area between these zones can expect a complex mix of winter precipitation, potentially cycling through heavy snow, sleet, freezing rain, and back to snow.
The storm will bring challenging winter weather conditions across the entire Fox 2 News viewing area. While meteorologists are still forecasting the accumulation amounts, they say that impacts to travel and daily activities are likely throughout the St. Louis region.
Temperature & Precipitation
The exact track of the storm and temperature will determine what kinds of winter weather fall across the area. Forecasters warn that this is a complex situation with warm air moving into the atmosphere that will create distinct zones of winter precipitation:
- North of I-70: Predominantly snow
- St. Louis and Jefferson County: Mixed precipitation zone (snow, sleet, and possible freezing rain)
- South of Festus: Higher potential for icy mix, primarily freezing rain and sleet with some snow
FOX 2 meteorologists will continue to monitor the system’s development. A more detailed forecast will be available as the storm moves closer to Missouri.
