With the storm now complete, we can step back and evaluate how this complex winter system unfolded — and how the Final Snow Call verified.
As expected, this event quickly evolved into a classic mixed-precipitation storm, with snow giving way to sleet and pockets of freezing rain as warmer air surged aloft. The key takeaway from the observed data is that sleet was the dominant ice contributor, not freezing rain. While freezing rain did occur and did accrete — generally topping out around 0.15–0.20 inches in the hardest-hit areas — its impact was limited by how long much of the region remained locked into sleet. That prolonged sleet phase capped glaze accretion on trees and power lines, but still created extremely hazardous travel conditions as dense ice pellets piled on top of existing snow. This also explains why impacts were widespread on roads and sidewalks, yet structural icing remained somewhat less severe than worst-case outcomes.
When comparing these results to the Final Snow Call, the forecast verified strongly in both placement and overall totals, especially considering the storm’s narrow thermal margins. The anticipated northwest-to-southeast gradient verified well, with 8–12″ totals northwest of I-95 and 4–8″ (locally lower) southeast, where earlier mixing occurred. Messaging correctly highlighted sleet as a major player, which is reflected in the final reports that combine snow and sleet — a detail that may cause totals to appear high to casual observers. While power outages did occur, they ultimately verified as isolated to scattered rather than widespread, consistent with the sleet-dominated outcome limiting ice loading on infrastructure. Minor background shading discrepancies are due to a NOHRSC alignment issue and do not affect the point data. Taking forecast accuracy, impact messaging, and outcome realism into account, this forecast earns a strong B+ to A- — especially for a storm where small temperature differences had outsized consequences.
The following are unofficial observations taken during the past 36
hours for the storm that has been affecting our region. Appreciation
is extended to cooperative and CoCoRaHS observers, Skywarn spotters
and media for these reports. This summary also is available on our
