HEAVY SNOW POSSIBLE FRIDAY

…POTENTIAL FOR HEAVY SNOW LATE WEEK…

Confidence is gradually increasing in a Friday period of accumulating snow, with the potential for 6 inches or more across portions of the area. While we remain several days out, guidance is beginning to converge on a more impactful scenario.

A strong Arctic air mass remains firmly in place through the period, maintaining a cold and highly supportive thermal profile for snow. Attention then turns to a potent Alberta clipper system forecast to track through the region late in the week. Model consensus continues to trend toward a more organized wave, with widespread snow signals appearing across multiple deterministic and ensemble suites.

Model Projected Snowfall Friday

Snowfall amounts will ultimately depend on several key factors:

• Depth of dry air on the front end, which could limit initial dendritic growth and produce finer, lower‑ratio snow.

• Moisture availability, particularly whether the system can tap into additional Atlantic energy, which would enhance lift and support higher snowfall ratios and a more robust clipper solution.

• 
  

At this time, the more impactful scenario is gaining support, but uncertainty remains typical for a 5–6 day lead time. The EURO (ECMWF) and CMC (Canadian) model solutions currently handle this pattern more consistently, while the GFS (American) continues to show greater run‑to‑run variability. Nonetheless, the overall trend across guidance favors accumulating snow with potential travel impacts—especially for the Friday morning commute.

Further refinements to track, timing, and snowfall amounts are expected as higher‑resolution data becomes available.
