FARGO — Over the next few days the jet stream is expected to drop closer to the Canadian border and it will likely bring with it an unpredictable, stormy weather pattern marked by warm, muggy days.
"The second half of the week through the weekend, there will be no fronts to focus a storm chance on," said John Wheeler, chief meteorologist for WDAY TV, which is owned by Forum Communications Company, along with The Forum.
"Instead, storms will form on little ripples of energy on the jet stream northwest of us, and it will be a daily forecast problem to determine how far south they come," said Wheeler, who anticipates daytime temperatures to reach the upper 80s to lower 90s, with night-time temps in the upper 60s to lower 70s from Thursday, June 27, through the weekend.
"It will be fairly humid through this period," said Wheeler, adding that while the probability of rain on any particular day will be relatively low — less that 50-50 — the probability of storms showing up somewhere in the region will be high.
Wheeler said the average number of 90-degree days in June is a little more than one day, so a stretch of two or three 90-degree days in June wouldn't be unusual.
He said the Fargo-Moorhead area's record for longest stretch of 90-degree days continuously in June is nine days in a row in 1995.
The National Weather Service is forecasting the following high temperatures over the course of the next several days: Thursday, near 85 degrees; Friday, near 88 degrees; Saturday, near 92; Sunday, near 88 degrees; and Monday, near 84 degrees.
