Environment Canada is warning of severe thunderstorms rolling through the region on Thursday afternoon.
The weather agency says that conditions are favourable for the storms that could bring strong wind gusts and heavy rain. It’s possible up to 60 mm of rain could fall.
“Localized areas that receive multiple thunderstorms are expected to see the highest amounts,” it notes. “Damage to roofs, fences, branches or soft shelters is possible.”
Another heat wave is expected to descend on Waterloo Region starting next week on Monday with highs above 30 and feeling closer to 40.
Thunderstorms and scattered showers are possible Thursday night as highs reach 27 C — feeling like 33 — and are expected to continue into the morning.
It will clear up midday Friday to make way for a sunny and warm weekend.
Both Saturday and Sunday will have mainly clear skies with highs of 26 and 27 C with less humidity as well.
A storm risk is back on Monday with a high of 28 C, which is also when the next round of humidity is expected to kick in. Tuesday could see a high of 30 C, feeling close to 40.
