Residents of Kingston should prepare for a significant drop in temperature early next week as a cold front moves through the region. After a mild Saturday with temperatures reaching 18°C, Environment Canada is forecasting a sharp change that will bring daytime highs down to just 4°C by Monday, April 20.
The cooling trend will begin Sunday night, April 19, when temperatures are expected to drop to -3°C. The forecast indicates the potential for rain showers or flurries during this time. By Monday night, conditions are expected to clear, with temperatures falling to -5°C. This overnight low is 7 degrees colder than the typical average low for this time of year.
While the temperature swing is significant, the cold weather remains within the range of normal expectations for late April. According to data from Current Results and The Old Farmer’s Almanac, the average date for the last frost in Kingston is April 28. This means that sub-zero overnight temperatures are still common well into the final week of the month.
The shift aligns with broader patterns identified for the season. The Weather Network had previously indicated that warm weather would likely lack commitment throughout April, with periods of milder conditions frequently offset by colder snaps. As of Friday morning, April 17, there were no active weather alerts for the Kingston area.
