Above seasonal temperatures continue in the GTA, but cooler weather on tap for weekend

The Greater Toronto Area (GTA) has been experiencing unusually warm fall weather, with temperatures surpassing seasonal norms since the beginning of the month. According to weather specialist Denise Andreacchi, Wednesday is expected to break the record set back in 1987, with a high of 21 C. Winds from the south are contributing to the mild air, reaching up to 40 kilometres per hour at times. The day began with a mix of sun and clouds, but showers are forecasted for later in the day, as the temperature drops to 14 C.

This warm spell is expected to continue through the rest of the work and school week, with highs ranging between 14-16 C. However, a change in the weather is on the horizon for the weekend, with temperatures cooling down to around 10-12 C on Saturday and Sunday, accompanied by overnight lows near 5 C. Weather experts predict that above-normal temperatures will persist across Canada during the remainder of November. The warmth is also extending to northern Ontario.

Mosquito populations in parts of southern and eastern Ontario and other regions across Canada appear to be thriving due to the warmer-than-usual temperatures, a result of a strong El Niño phenomenon. This natural cycle causes global temperatures to spike every few years, creating ideal conditions for mosquitoes to live longer in humid and warm environments. This year's El Niño is reportedly the strongest on record, based on the National Oceanic and Atmospheric Administration (NOAA) forecast.
