London and southern Ontario are facing two different weather challenges this week: a system expected to bring 5-20 cm of snow on Friday, along with the aftermath of Wednesday’s freezing rain that led to school closures and canceled buses. This discussion compares which storm will cause more travel issues, and how the type of precipitation influences responses in London and nearby areas.

Friday forecast for southern Ontario: what to expect in London
A fast-moving low-pressure system is set to hit Ontario on Friday, bringing with it 5-20 cm of snow across much of southern Ontario. Snow flurries are likely to start Friday morning, affecting areas from Lake Huron down to London and the Greater Toronto Area. As the day progresses into Friday afternoon and evening, snowfall rates will increase. Drivers should be cautious as roads may become slippery and visibility could decrease; it’s wise to allow extra time for any trips. Some regions like Windsor, London, and Niagara might see some snow turning into rain by Friday evening.Assessing Friday’s snowfall against Wednesday’s freezing rain
On Wednesday, a mix of freezing rain, ice, and snow caused major disruptions like school closures and bus cancellations due to ice build-up. In contrast, Friday’s forecast involves mainly snow rather than glaze-resulting in an expected accumulation of 5-20 cm. If we look at factors such as impact on travel, interruptions to services, and geographical extent-Friday’s weather could lead to slower but more widespread travel delays compared to Wednesday’s immediate hazards caused by freezing rain.Diverse storm patterns: insights from Colorado lows and Ottawa winds
The two weather events arise from different storm behaviors. The system hitting on Friday originates from the West Coast before making its way through the Prairies toward southern Ontario. Meanwhile, Wednesday’s freezing rain created localized impacts that resulted in school closures across specific areas. The snowfall from Friday will push eastward into Ottawa late that night continuing into Saturday morning; there’s a brief break expected on Saturday but temperatures will remain chilly with strong winds. Meteorologists are keeping an eye on a Colorado low arriving Sunday that may bring more significant snow or rain. Monday is predicted to be quite windy with colder temperatures setting in; bands of lake-effect snow are anticipated through Tuesday as well. While temperatures may rise again later next week, there’s potential for them to drop once more over the weekend. The key difference lies in how heavy snow bands move eastward into Ottawa compared to localized freezing rain seen earlier-this explains why responses differ between these events. A consistent approach helps clarify what each event means for residents. With an accumulation forecasted between 5-20 cm on Friday, we can expect significant plowing needs alongside visibility challenges; however, Wednesday’s freezing rain already led directly to closures or service disruptions such as halted buses and schools shutting down. Geographically speaking, while this week’s snow bands will cover a larger area-from Lake Huron through London all the way down the GTA-the effects from the previous freezing rain were felt more acutely where ice formed. The overall finding indicates that while both events create substantial travel slowdowns similar in scope-Friday’s situation arises due primarily through accumulating snow along with reduced visibility instead of surface glaze as seen previously. The next confirmed weather event worth noting is the incoming Sunday Colorado low-which meteorologists predict might bring additional impactful precipitation including both snowfall or rainfall.Source link
