Tillsonburg, Ontario is off to a sunny start this week, but residents should brace for changing skies as a low-pressure system from the Prairies is set to bring a risk of thunderstorms and gusty winds by Tuesday. Environment Canada says Monday will stay mainly sunny with a high of 26°C and a very high UV index of 9, before conditions deteriorate overnight.
As of 11:00 a.m. Monday, the temperature sat at 22.4°C with humidity at 56 percent and a falling pressure reading of 101.6 kPa. By late afternoon, southwest winds will pick up to 20 km/h, but the real change arrives Tuesday. Forecasters call for showers with the risk of a thunderstorm, southwest winds of 30 km/h gusting to 50 km/h, a high of 25°C, and a humidex making it feel closer to 32.
No weather alerts are currently in effect for the Woodstock-Tillsonburg-Oxford County region, but Environment Canada warns that severe weather can develop quickly. The incoming system could produce large hail, damaging wind gusts, heavy downpours, and even isolated tornadoes along the Highway 401 corridor, according to The Weather Network.
The unsettled pattern is part of an active summer severe weather season in Ontario. On average, lightning kills 2 to 3 people and injures around 180 each year in Canada, according to the Government of Canada. Residents with outdoor plans on Tuesday are urged to monitor forecasts and have a backup plan.
Looking ahead, the weekend of July 25-26 shows a mix of sun and cloud with a 30 percent chance of showers on Sunday and highs rebounding to 26-27°C, offering some relief from the mid-week storm risk. For now, road conditions can be checked at Ontario 511 for any weather-related impacts.
