Residents in Milton should prepare for a significant swing in the weather this week as a mild Saturday gives way to a cold snap that will bring overnight freezing temperatures. According to Environment Canada, the upcoming pattern includes a mix of rain and the potential for flurries early next week.

Saturday, April 18, is expected to reach a high of 19°C. However, the day will be unsettled, with showers arriving near noon and a risk of thunderstorms in the afternoon. Total rainfall is expected to reach up to 15 mm, and residents should plan for gusty conditions as winds reach 40 km/h.

The weather will shift drastically on Sunday, April 19, when temperatures will drop to a high of only 7°C. From Sunday night through Wednesday, April 22, overnight lows are expected to hit -3°C. These conditions bring a risk of flurries and frost, which may be a concern for those who have begun early gardening. While official frost advisories for the area typically begin around May 1, the forecasted dip into freezing temperatures is a reminder for residents to protect sensitive plants during this cold stretch.

The colder conditions will be short-lived, with a return to more seasonal, mild weather expected by Thursday, April 23. The forecast indicates that sunshine will return to the region, bringing temperatures back up to a high of 15°C.

While the temperatures will drop well below the seasonal average low of 2°C for this time of year, no active weather alerts were in effect for Milton as of Friday morning. Residents are encouraged to monitor updated forecasts throughout the week as the situation changes.
