Rain, Rain and More Rain

     This may sound like a broken record, but yet more rain is on the way later today for the RRV and Winnipeg as rain over southwestern Manitoba this morning gradually wraps around the system into the RRV. Rain may be heavy at times. Thunderstorms are not very likely in Winnipeg, but thunder will be possible closer to the Ontario border. Rain will likely continue tonight. Showers, unfortunately, will continue on and off yet again through the day tomorrow before finally tapering off tomorrow night.

      In total, there could be an additional 15-40 mm of rain by Tuesday morning in the RRV. For Winnipeg airport, this will be on top of the 123.1 mm of rain that has already fallen this June, which will place this June in the top 15 rainiest Junes on record since 1873. Other parts of the city have been wetter this month however, with 148.1 mm so far this month here in South St Vital. Even higher amounts have fallen in the far southeast corner of the city this June. To our west in Brandon, over 200 mm of rain has fallen so far this June as of this morning, only the 3rd time since 1890 that they have seen over 200 mm of rain in June. With yet more rain to fall today and tomorrow, this June will likely place itself as 2nd rainiest June on record in the Wheat City.

     A full summary of rainfall totals with this multi-day event will be posted alongside the June summary on Tuesday.

     Of note, winds will also be particularly strong today and tomorrow. Sustained winds over 45 km/h are expected for Winnipeg today, and over 30 km/h tomorrow. Even windier in parts of southwestern Manitoba where Brandon has seen sustained winds over 70 km/h at times this morning along with gusts over 90 km/h at times.

     Drier, warmer weather will return late this week.

  1. Was that 2005 when flooded basements throughout Winnipeg and Portage La Prairie (perhaps Brandon) were partially reimbursed by the city and Province.. Seems to me you could travel by boat from PLP to Elie and the PLP Bowes Modular home Plant was nick named Bowes Marina. I have some Pics I'll send you.

  3. The month of June will end on a dreary note this year, thanks to this weekend's soggy weather, which last occurred at this time, back in 2005. Me and my friends that were in Grade 8 had a farewell at Leila North School, where our fun activities in the last 2 days of school got cancelled due to unsettled conditions at the time. On the last day of school, me and my friends watched movies on a cart with TV and DVD instead of going outside, which we did until we got dismissed at 12:00pm.

  4. Yeah, truly remarkable rainfall amounts coming out of southwestern Mb and southeastern Sk. According to Environment Canada's summary, 100-200 mm of rain in general over the last few days. Brandon is now over 220 mm for the month with still more rain likely tonight and tomorrow... now officially 2nd rainiest June on record there. Rainiest was 258.3 mm in 1902 which will be very difficult to beat.

  5. Brandon has now had over 240 mm of rain so far this June with 45 mm of rain yesterday and about 5-15 mm so far today. This easily makes it 2nd rainiest June and they may actually have a shot at rainiest June on record if they get enough rain today. All they need to break the record is an additional 10-15 mm today.

    For Winnipeg, scattered showers will occur through the day today, and some may be heavy at times. Additional 3-6 mm is possible, perhaps even more if we get under any heavier downpours. Thunder is possible across southern Manitoba today, but I believe the chance for any given location is low. Winds will be strong over 35 km/h again.

    Tomorrow will be miserable to start. Clouds, chance of showers and windy conditions. We'll likely only reach a high around 16 or 17°C, likely reached late in the day when skies are expected to clear by late afternoon or so.

    Warmer weather on the way to end this week.

    1. Turns out it's also the 2nd rainiest MONTH on record in Brandon since 1890. Only other times they've had over 200+ mm of rain in a month were June 1902, August 1980, May 1999 and June 2005. A few of my family members there have had flooded basements so that seems to be a problem in the city right now.

      Winnipeg airport is up to 144.1 mm so far this June, so far 12th rainiest June since 1873.

    2. JJ..

      Daily data for June 1902 at Bandon CDA shows only 108.4 mm for the month, while the monthly summary for 1902 shows 258.3 mm for June. Not sure why the discrepancy. Looking at nearby sites for June 1902 doesn't show widespread big totals.. so I'm kind of suspicious about that 258 mm total. May have been an error in data processing... will need to look into it further. If it's an error, then this month is easily Brandon's wettest ever.

    3. You have got to be kidding me...

      Thanks for pointing that out Rob.

      I'm at a loss of words at how dissapointing the climate data archive is. I have yet to find a single city without significant data errors like this one.

  6. JJ, is this active stormy pattern expected to continue into July?

    Thanks, Anon

    1. I wont go into what mid and late July will look like because that's just too far away for me to give you something that I can be confident about.

      Looks like the pattern will become a bit more active by next weekend into early next week. Our next period of opportunity for storms looks to be then.

  7. Looks like June will actually finish a tad above normal in terms of temperature compared to the 1981-2010 normal. June should finish with average of 17.0°C or 17.1°C, pretty much bang on the 1981-2010 normal of 16.9°C.

    However, this does not mean the streak of below normal months is finished. For the below normal streak records that I have collected, I use the normal of the previous 30 years - so for this year, the 1984-2013 normal. The 1984-2013 normal is 17.1°C and so if we finish off at 17.0°C, June will mark the 9th consecutive month below normal. It will depend how warm we get this afternoon and how cool we get before midnight this evening.

  8. Turns out the low pressure we have seen in the last 24 hours with this system has been unusually low for this time of year. Will have the finalized stat in tomorrow's June summary, but all I'll say now is that the minimum sea-level pressure reading of 98.6 kPa last night was among the top 5 lowest pressure readings in June on record since 1953. This system is quite strong for this time of year.

  9. June summary to come around midday or so...

    Drizzle and showers this morning. Overall, a miserable day. We wont warm much, likely only reaching around 15 or 16°C for a high, a good 10°C below normal. Cool night tonight dropping into the single digits after clearing skies late this afternoon or early evening.

    Much sunnier day tomorrow and Thursday with highs near 22°C or so tomorrow and around 24-25°C Thursday. Winds will be light on Thursday which will be a nice break.
