Pembroke, Ontario, is in for a warm and mostly sunny week following a risk of thunderstorms Monday evening, according to Environment Canada. Daytime highs are expected to climb steadily from 21 C on Monday to a peak of 31 C by Thursday, well above the early June norm.
Monday will see a mix of sun and cloud with a high of 21 C, but the late afternoon and early evening bring a 40 per cent chance of showers and a risk of a thunderstorm before skies clear overnight. The bigger story for gardeners and farmers is a risk of frost, with the low dropping to 3 C. While unusual for early June, such late frosts are not unheard of in the Ottawa Valley.
Starting Tuesday, conditions settle into a stretch of mainly sunny days. The high will hit 22 C on Tuesday, then jump to 30 C on Wednesday and 31 C on Thursday. Overnight lows through the week will range from 3 C to 14 C, with some cloudy periods mid-to-late week. With no weather alerts in effect as of Monday, residents can look forward to ideal conditions for outdoor activities midweek.
This quiet weather is a sharp contrast to the pattern earlier in May, when the province saw its first tornado of the year on May 9 and Pembroke faced severe thunderstorm watches around the Victoria Day long weekend and the days that followed. That active pattern has since eased, though forecasters remind residents that May and June are peak months for severe weather in the region.
The heat will ease by Friday, when the high drops to 23 C and a 30 per cent chance of showers returns. The weekend outlook currently includes a high of 26 C on Saturday with a similar chance of showers, followed by sunny skies and 27 C on Sunday.
