The long hot dry summer of 2011 continues today over southern Manitoba with another 30C+ day on tap.. our 4th in a row in Winnipeg, and the 23rd occurrence of 30C or more temperatures this year. Several record highs are likely again today over southern Manitoba, including Winnipeg where 1998's mark of 32.4C set on this date in 1998 is in jeopardy. Another summerlike day is expected Sunday with temperatures in the upper 20s, not quite as hot as today as we get into a light northeast flow of somewhat cooler air.
Big changes are on the way though as we get into Monday and Tuesday. A cold front will push through southern Manitoba Monday with clouds and a chance of showers, with gusty northwest winds developing bringing in cooler air. By Tuesday and Wednesday, high temperatures will only be in the low teens along with clouds and brisk northwest winds along with some lake effect showers off the Manitoba lakes. High pressure will build in by Wednesday and Thursday which will likely produce the season's first widespread frost to southern Manitoba. Moderating temperatures are expected by the end of the week into next weekend as temperatures return to more normal values for this time of year (around 20c). So enjoy the warm weekend.. this could be summer's last hurrah!
