After a prolonged and sudden stretch of normal to below-normal temperatures, warmer weather is on it’s way for Winnipeg.
The long-wave trough that has remained solidly parked over the Eastern Prairies over the past week is finally pushing off to the east, allowing a building upper ridge over British Columbia to spread eastwards into the Prairies and bring with it some milder Pacific air. With an incoming upper ridge, our chance for precipitation over the next few days is pretty much nil. We’ll see temperatures climb to about 17°C today, which will be a couple of degrees above our normal daytime high of 15°C for this time of year. Things warm up on Thursday as a warm front pushes through and we climb to a high of 23°C. Temperatures will remain in the low 20’s right through the weekend under sunny skies.
A Dry End to September
Rob put up a great summary on the precipitation situation for Southern Manitoba this month.
As of [September 24, 2012], only 4 mm of rain has fallen at Winnipeg airport this month, with no precipitation forecast all this week through the end of the month. If so, September will end up as the 2nd driest September on record in Winnipeg since records began 140 years ago in 1872.
I highly recommend you head over and read the brief summary Rob put up. It continues to look like we’ll be dry through the end of the month, so there’s a very good chance that Winnipeg may see it’s second driest September on record. We’ll have a complete summary for the month of September on Monday, October 1st in addition to our regular post.
