Antigonish, Nova Scotia is in for a week of weather whiplash, starting with a risk of frost tonight before temperatures soar to nearly 30°C by mid-week. Environment Canada says a clear, cold night will drop the mercury to 4°C, bringing a late spring frost threat before a dramatic warm-up pushes highs to 29°C on Wednesday and Thursday.
Strong north winds gusting up to 60 km/h will ease later today, making way for clearing skies. The steep temperature swing is typical for this time of year, but it arrives just days before the average last frost date of June 13 for this part of the province, based on records from the Collegeville climate station.
After a chilly start, Monday will reach 13°C, but by Wednesday the thermostat climbs 16 degrees higher. The Environment Canada forecast shows a mix of sun and cloud through the week, with the UV index hitting 7, which is considered high. Residents are being reminded to wear sunscreen and cover up during peak sun hours.
The normal June high for this region is 19°C, so the mid-week spike is well above average. The short growing season here averages just 93 days, from about June 13 to September 15, so gardeners are being especially cautious with tender plants tonight.
Overnight winds will become light this evening, increasing the risk of frost damage. Once the warm air settles in, however, temperatures will stay mild into the weekend, though a downturn in temps is likely by Friday.
