Nice week ahead!
Looks like we could be seeing the nicest stretch of weather of the summer this upcoming week! Models are indicating an upper ridge building over the Prairies which will block any weather systems from moving into southern MB over the next few days. This will bring plenty of sunshine with high temperatures in the mid 20s through mid week.. which is actually a little ABOVE normal for a change(now 22c) The upper ridge will flatten a bit by mid week then rebound again for the end of the week into next weekend.. bringing more dry weather and warm temperatures. At this point, models are indicating the next significant threat of rain won't be until Labour Day.. so it will be a good stretch of dry weather to finally start drying up some of those water logged fields over southern MB. We need it.

ReplyDeleteWhat is the mean temperature at the Winnipeg airport so far this month>>>
August below normal month so far????
As of the 29th, the mean temperature at YWG airport was 17.4C, which should be close to the final average. This will be a degree below the normal August average of 18.5C..
ReplyDeleteThanks for the stats Rob!
ReplyDeleteRecords are meant to be broken with 9 MONTHS of below temperatures now!
This week really does look like a very nice span of weather!
It is so funny how it comes on the last weeks of summer!
Oh well better late than never!!
The well advertised string of 9 consecutive months below normal will be the longest such streak in recent memory for Winnipeg. In looking through the entire period of record from 1971 to present, there has never been a streak of 9 consecutive months below normal (2 occurrences of 8 months below)
ReplyDeletePrior to 1971, the last time a 9 month below normal streak occurred was December 1949 to August 1950 (using 1941-1970 normals). That year had a lot of similarities to the current situation: It was also a 9 month period from December to August, with a big spring flood (the May 1950 flood). Interestingly it was followed by a warmer than normal September and October, a colder than normal November to January and an above normal February.
Before that, you'd have to go back to the 1880s to get longer cold streaks. During this decade there were some incredible cold periods that were much longer than 9 months. Using the 1881-1910 normals, the longest streak was 18 consecutive months below normal from November 1882 to April 1884. This was followed by one normal month (May 1884) and one above normal month (June 1884) and then another 16 consecutive months below normal from July 1884 to October 1885. In other words, in the 36 months between Nov 1882 and Oct 1885, there was only one month above normal.
During that period, one of the biggest volcanic eruptions ever recorded on Earth, Krakatoa, occurred on August 26-27, 1883. This likely was a major factor to the prolonged cold spell back then.
Rob If it takes a month in Italy for you to come up with this great stretch of weather please leave earlier next year.lol
ReplyDeleteThe 7 days were in now not the 9 months
