Residents in Milton should prepare for a significant drop in temperatures late this weekend as a cold snap moves into the region. According to Environment Canada, overnight lows are expected to reach -4°C on both Sunday, April 19, and Monday, April 20.

This cooling trend marks a sharp change from the warmer weather experienced earlier in the week. Daytime temperatures are set to fall from recent highs to a predicted 6°C by Sunday and Monday, which is well below the typical seasonal high of 12°C for this time of year.

The cold weather poses a particular risk to gardens and early outdoor plantings. With the average last spring frost date for the area typically occurring in late April to mid-May, local gardening experts advise that it is too early to put out tender vegetation. Plants such as tomatoes, peppers, basil, and eggplant are highly susceptible to frost damage and should be kept indoors until the risk of freezing temperatures has passed.

Meteorologists suggest that this fluctuating weather is part of an unsettled spring pattern across Ontario, driven by factors including a split polar vortex that allows colder air to move into the province. While no specific weather alerts were in effect as of the morning of April 15, residents are encouraged to monitor local updates as conditions can change rapidly.

For those looking to stay informed on the latest local conditions, additional information is available through The Weather Network, while gardeners can find further guidance on seasonal planting at The Old Farmer’s Almanac.
