Cranbrook could be breaking some records over the weekend and heading into next week as temperatures are expected to spike over 30 C.
According to forecasts, temperatures are expected to rise to 32 C and 33 C on Sunday and Monday, which would break current records. Sunday’s record is 30.6 C, set in 1957, while Monday’s record is 31.1, set in 1949.
Matt MacDonald, a meteorologist with Environment Canada, attributes the high temperatures to a ridge of high pressure that’s developed over the entire province.
“As the ridge builds in, it allows some really warm air to move north from as far south as California,” said MacDonald, “so we’ll be under a California-type air mass, if you will, over the weekend.
“Temperatures will peak either Sunday or Monday.”
Cranbrook temperature records extend all the way back to 1901.
“The normals for this time of year is 22 C, so we’re going to be a full 10, 11 degrees warmer than normal and we’ll be in contention to break a few records,” said MacDonald.
Following the high temperatures, MacDonald warns that there could be a chance of thunderstorms by late next week.
“Usually what happens after a big ridge of high pressure breaks down, we get a thunderstorm outbreak,” MacDonald said, “so that’ll be something to keep an eye on. Obviously hot and dry conditions followed by lightning is not ideal, so definitely something to be wary of.”
From a seasonal standpoint, MacDonald says the spring has been warmer than normal, with that trend extending up until mid-July.
“A lot of that is owing to the Pacific Ocean, which has been warmer than normal,” MacDonald said. “Of course, we’re coming off the tail of a record-breaking El Nino and it is gradual fizzling out, nevertheless, there’s still remnants of that warmer than normal water and owing simply to the fact that most of our weather comes in from the west, the air masses approaching B.C. are inherently warmer than normal.”
