April ends on cool damp note as below normal streak continues..

Same story.. different month
Below normal temperatures dominated
in April, much like March and February
A cool damp day over Winnipeg and southeast Manitoba marked an appropriate end to the month of April, which will end up as the 7th straight month below normal in Winnipeg. The month will finish with an average temperature of +0.3C, over 4C below normal for April (1981-2010 normal April average of +4.4C), making this the 19th coldest April on record since 1872, tied with the Aprils of 1962, 1888, and 1877.  This follows the 19th coldest March and 21st coldest February, so we've had top 20 type cold weather for 3 straight months now. And it doesn't look like the weather pattern will be changing anytime soon as a persistent upper trough over central North America maintains cooler than normal weather over southern Manitoba through the first week of May at least. Normal highs for Winnipeg are now 16C and will climb to 19C by mid May and 22C by the end of May. If we can even get back to a normal weather pattern by mid May, we would be seeing more frequent and persistent 20C weather. Winnipeg has yet to hit the 20C mark this year, and has hit the 15C mark only once with a high of 15.1C on April 23rd. But there have been worse starts to May.. such as 1979 which saw single digit highs for the first 11 days of the month along with snowflurries almost each day, and a 7 cm snowfall on May 10-11th. Whatever the case, residents of southern Manitoba are eager for a pattern change.. which hopefully comes by the beginning of summer.

Latest dates that Winnipeg first reached 20C (data since 1872) 

1.   May 25 1907
2.   May 21 1956
3.   May 18 1996
4t.  May 17 1935, 1967
6t.  May 16 1883, 1892, 1979
9.   May 15 1884
10. May 14 1902

    1. You and me both... At least storm season is getting closer which will give something else to talk about soon!
      Interesting about those latest first 20°C dates... At this rate, a top 10 finish may not be out of the question!

    2. It's horrible. This weather is liking living in Scotland or something. Cool, unsettled, no warmth.. depressing and boring. Yesterday was so nice.. sunny and 16.. right on normal, no complaints. You think we could have even TWO days in a row like that?! Not this year! Sure will be nice when Mother Nature makes up for this lousy weather with a great summer, fall and winter, right Mother Nature?! Right?

  2. Hello Rob. I was going through the University of Manitoba weather central webpage and came across a section called interesting weather events. When I clicked on the July 24 2000 Brunkild Tornado, I saw your name on the Write up. Did you actually chase that tornado?? Is that your picture at the top of the page??

    1. No I didn't chase that storm, or take the photo. The photo was taken by Prairie Weather Dog storm chaser Pat McCarthy who was on that storm, almost 15 years ago now. Hard to believe it was that long ago..

  3. Just looking at our stats from last year.. we hit our first 20 and 25C of the year on May 6th with a high of 25.2C.. so although it took longer to hit our first 5C and 10C last spring, we got to 20C quicker than this year. I just hope we don't challenge that 1907 record for latest 20C this year!

  5. Rob, are you looking for warmth?? Well I found some. It's just that you have to drive over 1000 km to Oklahoma City, where temperatures will be approaching 100 F this weekend :)

    1. Pretty sad that you have to drive 1000 km for hot weather at this time of year, when we could be having it right here!

  6. The long range forecast looks wonderful this upcoming week.....if you are a fish. I just hope that this spring / summer is not a wash out. It's bad enough with these cool temps, never mind a wet and soggy summer too!!

    1. Yes, the outlook this week is not very encouraging. Cool start then more wet weather by mid to late week. Could be worse... Calgary woke up to 15 cm of snow this morning with another 10 cm on the way! Eastern Canada isn't much better. This just goes to show how widespread this cool air pattern is across the country... which doesn't bode well for those of us looking for a quick warmup. I've resigned myself to the likelihood of yet another below normal month... and can only hope that we reverse the pattern by summer.

  7. Eastern Canada has been and will be warmer than us especially later in the coming week with temps forecasted to be in the low to mid twenties over Southern Ontario/Quebec.

    Winnipeg is pretty much the only major canadian city not to reach 20C yet to this point. And to make matters worse it's not likely we'll see our first 20C for at least another 2 weeks or so as well below normal weather is expected to continue into mid month and perhaps beyond.

  8. Rob any thoughts on the upcoming 2014 El Nino?

    1. There are growing signals that an El Nino will be developing by the summer or fall, and continue through next winter. The big question is.. how strong will it be? That will have a big impact on how the El Nino affects us here in southern MB. If it's a fairly weak El Nino, then impacts will be felt mainly along the West Coast, with minimal impacts here in southern MB (and greater influence from other climatic oscillations such as the Arctic Oscillation). If it's a moderate to strong El Nino, then there's a greater likelihood of it impacting us.. including a warmer winter with less snowfall. I'm certainly hoping for the latter..
