It was an absolutely spectacular Monday in much of Southern Manitoba, but even though it was a sunny, breezy and hot day it appears it wasn't quite record setting. According to data from Environment Canada, in order for new records to be set across the Pembina Valley, daytime highs had to push above at least 33 degrees, and even thought it was warm, it wasn't that hot.

"It was pretty much the same set-up Monday as we saw Sunday," explained CMOS Accredited Weathercaster Chris Sumner. "Upper level atmospheric ridging over the region, alongside a strong southerly to southwesterly flow, meant hot, dry air from the U.S. southwest was transported to our area. Humidity levels both Sunday and Monday dropped into the mid-teens at points during the day which is unusually dry for us."

Noticeable drop in temperatures
"A cold front swept through the area early Monday evening, starting around 6pm, with temperatures dropping nearly ten degrees in about ninety minutes," said Sumner. "I was actually out on the golf course when it happened, and you could feel the air temperature change significantly. That's how quick the drop was."
Northwesterly gusts close to 60km/h were recorded in the 6pm hour Monday evening at several points in the Pembina Valley, pointing to the arrival of that cold front.
"For Tuesday, we have surface high pressure pushing into the region, which will ensure a mainly sunny day, but also lead to northerly winds gusting to 50 km/h alongside that sunshine, as we reach for a seasonal high of 19 this afternoon," he added. "Wednesday will be a few degrees warmer, and then it's looking like we will be heading back into a similar pattern as this past weekend, generally speaking. Atmospheric ridging over the region is expected again, leading to well above average air-masses for this time of year being pushed northward for much of the back half of the week and into the weekend."
Averages for this time of year are 19 degrees daytime and 4 degrees overnight.
