Prairie Weather Advisory

We are monitoring an incoming weather system expected to impact the Prairie region on Thursday, April 16 — and if all goes to plan, this will be our last “surprise return to winter” of the season (hopefully). The most significant operational effects are expected along the Regina–Winnipeg corridor.

Overview

A late-season winter system will move through the Prairies on Thursday, bringing a mix of snow, reduced visibility, and potential freezing rain as it tracks eastward. Conditions will deteriorate through the day, with Manitoba expected to see the most significant impacts.

Regional Impact Summary

Manitoba (Winnipeg inbound/outbound)

• Snow developing through the day, increasing in intensity
• Potential transition to freezing rain later Thursday into Thursday night
• High risk of travel disruption and reduced highway traction
• LCV operations may need to be restricted or converted to singles depending on conditions

Saskatchewan (Regina and surrounding corridors)

• Periods of snow and reduced visibility expected
• Conditions deteriorate eastward through the day
• Regina–Winnipeg lane identified as highest risk segment for delays and potential LCV restrictions

Alberta (Calgary–Edmonton corridors)

• Mixed precipitation possible, generally less severe impacts
• Minor delays and reduced speeds possible, but operations largely maintainable

We will continue to monitor the system and provide updates as conditions evolve. Please ensure planning decisions reflect the potential for rapid deterioration, particularly in southern Manitoba and eastern Saskatchewan.
