Temperatures soar into mid to upper 30s over southern Manitoba

It was a record hot day over parts of southern Manitoba Wednesday as a brisk southerly flow pumped in some of the hottest air of the summer into the region. Temperatures soared into the mid to upper 30s over the Red River Valley and SW Manitoba, the 20th day this summer with highs of 30c or more in Winnipeg (normal is 13) Winnipeg's high of 35.4C tied July 29th as the hottest day of the year in the city, while temperatures soared to a record 36.9C in Brandon and 37.9C in Dauphin, the hottest spot in the country. Even hotter temperatures were recorded south of the border, including 40C in Minot, ND and 44C in Chamberlain, SD.  A cold front pushing though tonight will usher in cooler but still above normal temperatures for Thursday and Friday with highs in the mid 20s, before another shot of 30c weather for Saturday.

Record temperatures across southern Manitoba Wed Aug 29...

    If today was 2 degrees warmer than EC predicted
    So tomorrow 29C + 2C = 31C. We might have a shot at another 30C.

    Mark.. Best precip chances for Winnipeg this weekend will be Sunday when a slow moving cold front starts pushing across the RRV. A few showers and some local tstorms possiible. Models are also hinting at a smaller chance of some showers or weak thunderstorms Saturday morning along the warm front that is spreading in the warmer air through the day.

    Nice to get such very low dew point temperatures on this last hot day of August. Makes it so much easier to take the heat. Kinda like a cool summer day in Arizona out there.

    I was wondering how much above normal was the month of August.

    August 2012 will end up with an average around 19.3C at YWG airport, which is 0.8C above normal. We were actually below normal up to the 21st, but above normal temperatures over the last 10 days of the month ( including 5 days of 30c or more) pushed August to an above normal average. That makes an amazing 14 straight months now with monthly temperatures averaging above normal, an unprecedented stretch of wamth in Winnipeg's climate history dating back to 1872.

    I was amazed Winnipeg got as hot as it did today, with a high of 31.6C. Nice dry air plus a SW downslope wind gave us maximum heating today. If we had a similar setup on Wednesday as today, Winnipeg could have hit 40C that day.

    No problem. By the way, correction on my stats.. we've had 6 days of 30C or more over the last 10 days, 21 on the year. Could see another one this weekend.

    Hi Rob, How is our thunderstorm potential looking for the next few days, with our next system? Anything strong to severe?

    Mike.. We may see some tstorm activity tonight as a strong southerly low level jet moves in over the RRV ahead of Sunday's cold front, but I don't expect anything strong or severe. Any activity will push into the interlake and eastern MB Sunday morning with a drying trend in the afternoon.
