Snow Storm Weather Forecast: Two Rounds Expected in St. Louis Jan 24–25

Why this snow storm weather forecast matters

Accurate snow storm weather forecasts are critical for public safety, transport planning and local services. The National Weather Service in St. Louis has issued guidance for the weekend of 24–25 January 2026 as a major winter system is expected to impact the St. Louis metropolitan area and surrounding regions. The forecast is relevant not only to residents and commuters in the Midwest but also to emergency services and local authorities preparing for heavy precipitation and extreme cold.

Main forecast details and recent updates

Timing and structure of the storm

According to the National Weather Service in St. Louis, the system will arrive in two rounds. Meteorologist Alex Elmore reported the first round beginning Saturday morning, 24 January, and continuing into the evening. A second round is expected from late Saturday night into Sunday morning, 25 January. The two-stage arrival increases the window for accumulating precipitation and complicates response efforts.

Snow, ice and cold

Initial forecasts emphasised heavy snowfall and dangerously cold temperatures across the region. A more recent update (dated 22 January 2026) indicated the event may evolve into more of an ice storm than a pure snow event. That shift raises particular concerns: ice accumulation can lead to more hazardous travel conditions and greater impacts on trees and overhead lines than an equivalent amount of snow.

Operational considerations

Reports note that salt treatment can be limited in effectiveness when temperatures fall very low, a factor already highlighted in related briefings. State authorities in Illinois have urged readiness ahead of the weekend storm, reflecting the potential for significant disruption.

Local contrast and outlook

By contrast, the current weather at Harbour Island, Bahamas, shows clear skies with a temperature of 24.2°C (75.6°F) and easterly winds around 13 mph, illustrating the sharp regional contrasts in conditions across the same period.

Conclusion and what readers should expect

Residents in the St. Louis area should prepare for a complex, multi-round winter event for 24–25 January that may include heavy snow, significant icing and dangerously cold temperatures. Expect changing forecasts; follow National Weather Service updates, heed local emergency guidance and allow extra time for travel if movement is necessary. The potential shift toward icing elevates the risk to infrastructure and travel, making early preparation advisable.
