Severe thunderstorms over southwest Manitoba Sunday evening.. showers/storms bypass Winnipeg/northern RRV yet again..









Some stunning images sent to the Weather Network of locally severe thunderstorms that affected southwest Manitoba last evening. The left image shows a shelf cloud passing over Oak Lake, MB which produced strong wind gusts, heavy downpours, and quarter size hail. The right image is a beautiful shot from Virden of mammatus clouds being underlit by a setting sun. Mammatus cloud sometimes accompany tornadic storms, and this cell did indeed produce a brief tornado just east of Virden Saturday evening. The strongest storms generally moved from the Transcanada highway near the SK border down towards the southern RRV last night, once again bypassing Winnipeg and the northern RRV. About 5-15 mm of rain was recorded in storms last night over the southern Red River valley.

These storms come from the same system that pounded southern Saskatchewan Saturday with some exceptionally heavy rain and hail north and east of Regina. Hail up to a foot deep fell on Highway 6 north of Regina Saturday afternoon (image left) which disrupted travel in the area. 50-70 mm of rain flooded areas just east of Regina along with hail and local funnel clouds.

  11. Are any of these showers going over Winnipeg lake-enhanced? It appears as if there are areas of precipitation calving off of lake Manitoba.

  16. I was just enjoying this extended warm August sun. Then last week some prophetic comments of winter in August . Next an NWS RR Spring flood informative caution and now Prairie roads blocked by over a foot of the white stuff.
    The Jets don't need this much help.

  17. I've measured 23 mm here in south end since June 23, that includes today. Absolutely stunning. Other parts of city got more, still amazingly dry. Hoepfully today was a sign of a wetter pattern upcoming but I don't have my hopes up at all.

  18. Hi from down south..

    Long time since I posted. But ran across an article yesterday in regards to job cuts in the met department of Env Canada. Sorry to hear that.

    I was also suprised to read about the dryness in Winnipeg area. I didnt realize this. Grand Forks area has been more normal...while we all know the southern Red River basin from Fargo to the headwaters has been very wet with total rainfall since June 1 of 10 to 15 inches. Fargo has had 3.80 inches this month.

    I live in st.James closer to bruce avenue and strathmillan school, and last night we had nonstop heavy downpours from 4pm to 11pm. the heaviest happened around 5pm i expected to hear a few cracks of thunder with how heavy it was, but it never occured. I was also unable to get a rainfall reading as I don't have a rain gauge but i hope to get one soon. I estimate we had at least 5-10 mm of rain last night. we needed it, I'd still love to see one good storm before the summer ends. I don't care when it hits I just need to see one soon. let us know when we have a chance rob. thanks.

  20. Hi Dan..

    Good to hear from you. Yeah, it's been a crazy summer for us... feast or famine up here. Amazing how we keep missing storms around Winnipeg, but just 30 miles south of us they've had almost normal amounts of rain this summer. Love the sunny dry weather.. but like most people, wouldn't mind seeing a good thunderstorm or two before the season ends..

  23. Seems like everyone trys to ignore me. Am I boring?, you can tell me how I can improve, let me know.

  24. Hey Mike,

    Since it's a Wednesday afternoon, people are likely working or otherwise busy, and there isn't often too much chatter when there's no weather going on.

    I don't think we'll see much in the way of storms this week, but there is a chance that Winnipeg will get some rain overnight on Thursday and through the day on Friday, but I get a feeling that the South Perimeter Shields© may go up and keep us dry. Looks like more nice weather through the weekend and the first half of next week.

  25. Whoops, I forgot about today. I'd say there's a slight chance of a thundershower in the city in a hour or two as some weak instability moves into the area. If it happens, it'll be nothing big, just some moderate rain and a few rumbles of thunder.

  26. Hi Rob!

    Knowing that you are a "weather nut" like the rest of us I would also like to ask you if you have any interest in Astronomy and the cosmos????
    I have always wondered if the people who have a passion for weather also will somehow be drawn to the stars???
    Just thought I would ask??? Thanks!

  27. Daniel..

    Yes, many people interested in meteorology are also interested in astronomy. Me, just a passing interest.. I like to watch the night sky on occasion, but I'm not an avid follower like some people.

    Although I hear there's some northern lights possible around here the next few nights.. that celestial phenomenon always interests me.

  28. Mike..

    As b7 mentioned, there's a chance of some storms Thursday night into Friday, but once again looks like the main activity will be bypassing Winnipeg to the south, with the best chance along and south of the intl border. The last time a thunderstorm was officially observed at Winnipeg airport was back on July 4th.. 5 weeks ago. Very unusual to go this long without a thunderstorm at peak thunderstorm time..

  29. Could be worse though.. you could be living in Wichita Falls Texas where they just recorded their 50th consecutive day over 100F today, with 1 day of measurable rain (0.5 mm) since May 25th.

    ReplyDelete
  30. Correction.. they picked up 1 mm yesterday!

    ReplyDelete
  31. Thanks B7, I'll try and remember that next time I post, as you put it other people are working or busy. that is pretty much the same thing for me, so I understand.
    Thanks.
