Summer like weekend.. cold front expected late Monday
It looks like Mother Nature is making up for her prolonged memory lapse this summer, with a nice warm finish to the summer holidays this weekend. The warm weather of the past few days will continue today and through the holiday weekend with temperatures in the upper 20s, possibly hitting 30C Saturday and Sunday. Labour Day Monday should continue to see warm temperatures, but a cold front is expected to push through late Monday into Monday night, triggering a few showers and thunderstorms as it crosses southern MB. The unsettled weather is expected to move out Tuesday with drier and slighly cooler weather as the kids head back to school. Long range guidance is indicating above normal temperatures returning by mid September.

You know how busy the beaches and parks are going to be this weekend!
The weekends for the whole summer up to now have pretty much been a write- off!
Does it look to be Humid this weekend?????
Yeah, it'll be nice to be at the beaches this weekend, although lake temperatures are only around 20C.. a little too cool for a dip, for me anyways. Nice to be outside though.. except for those blasted mosquitoes! (they're awful in Charleswood)ReplyDelete
Humidity wise, dewpoints through the weekend should be similar to the past few days.. around 15-18C which is a bit sticky for this time of year, but nowhere near as muggy as the 20-25C dewpoints we sometimes get in July during the height of the growing season.
The cold front timing could lead to 'interesting' weather, or not.ReplyDelete
And the long weekend is off to a good start. The mercury hit 26.7C today (Silver Heights) with a dewpoint that sat between 13 and 18C throughout the day. My sunshine recorder is definitely showing the approach of fall as the watts per metre squared continues to drop day by day. Enjoy the weekend everyone.ReplyDelete
Skies have cleared and temperatures climbing nicely this morning. We're a couple degrees warmer at 850 today, so I think Winnipeg should make it to 28C this afternoon (26C yesterday) Some localities over SW MB and western RRV (Portage to Morden) may even touch the 30C mark today. Better chance of more widespread 30C temps Sunday, especially over SW MB, as 850 temps climb to 20-22C.ReplyDelete
30C mark reached at Brandon, Carberry, Carman and Melita today. Looks like a repeat tomorrow, with 30-33C readings likely over portions of the RRV and SW MB. Winnipeg hit 28C today, and with 850 temps a bit warmer tomorrow, I think we have a good shot at reaching 30C tomorrow afternoon. 30C readings will be more likely to our south and west.ReplyDelete
Will there be any chance of a severe thunderstorm tomorrow night????
I don't think so. The SPC's forecast rules us out, but we may see at least one or two non-severe pop-up ones.
Front is coming through RRV at a low time for severe weather (Tuesday morning) Models however do show heavy QPF over southwest MB Monday night where the better instability will be, with max rainfall amounts over 50 mm within 12 hrs. Dewpoints are still running at 15-18C in the southerlies over southern MB, with a fairly strong jet moving in by late Monday, so the possibility is there of some locally strong thunderstorms developing by Monday evening over SW MB with heavy rain as they train along the slowly advancing cold front. SPC does mention the risk of some isolated severe storms with the front but at this point, widespread severe storms are not anticipated.ReplyDelete
