However, there is one record we broke yesterday. With a minimum of 17.9°C, that breaks the old record high minimum of 17.2°C in 1967. This is the 3rd daily high minimum record Winnipeg has broken in the last 2 weeks. This reflects the unusually high humidity for so late in the year we have seen this year.
Speaking of humidity, it was surely quite humid yesterday. With a max hourly dewpoint observation of 20.3°C, that was the highest dewpoint in September since a reading of 21.8°C on Sep 5, 2005. It is also only the 30th occurence of dewpoint over 20°C in September since 1953. The highest ever in September was 23.4°C on Sep 2, 1983.
In addition, humidex reached 40.4 yesterday. This is only the 4th occurence of humidex over 40 in September since 1953. In addition, it is the also the 4th highest humidex in September... and latest occurrence of humidex over 40 ever.
Highest humidex values in September since 1953...
1. 45.9 on Sep 2, 1983
2. 41.4 on Sep 5, 1978
3. 41.2 on Sep 2, 1960
4. 40.4 on Sep 6, 2013
5. 39.2 on Sep 10, 1998
Thunderstorms sparked along a cold front just east of Winnipeg yesterday late afternoon and evening. I chased the storm with Matt from A Weather Moment... because who knows, this may be the last chase of the year. Here's a couple photos below. Not the best storm we've ever chased, that's for sure.. but not bad for September.
Ain'nt loook we gonna get no more days like yesterday.
ReplyDeleteyou are darn right,
DeleteIf anyone wants to know why winnipeg never gets storm click on my name and you will find out.
ReplyDeletethat is super funny comic. ha ha ha.
Deletesuper funny. and it is right :)
Deletei love this blog so many people talk on it.
ReplyDeleteI think my forecast right now is a little pessimistic actually for Sunday and Monday. Bulk of rain and storms are expected to remain to our south right now. Don't think we'll see significant accumulations in Winnipeg based on what I see right now. We are in the year 2013 after all...
ReplyDeleteTough call for tonight. A very sharp line between the high rainfall amounts and low amounts is expected tonight. South of this line, 25-50 mm of rainfall could fall tonight, especially if there are thunderstorms. North of the line, minimal accumulations would occur. Unfortunately, it looks like Winnipeg will be right near this line. As a result, it's quite difficult predicting what Winnipeg will get because we could end up on either side.
ReplyDeleteI tend to favour the further south solution, but it isn't a guarantee.
NAM-10 MM
DeleteGFS-36 MM
GEM-62 MM
Whitch is our best bet.
I hope GEM is right.
Deletei sadly dought it though.
DeleteI think a safe call is 2-30 MM for the peg.
DeleteI would agree although there is small chance of higher amounts.
DeleteThen how about 2-30 MM+?
DeleteSounds good.
Deleteextra small chance of 2- MM.
DeleteTroll.
DeleteBulk of rain looks to remain to our south with impressive amounts of 50+ mm expected south of the border. Looks like just a chance of a few showers in Winnipeg with maybe a few mm if we're lucky. Still uncertain though because it doesn't take a big change in the track of the system to change rainfall amounts significantly.
ReplyDeleteThe Perimeter shields are back in action! The rain shield has just been scraping the south Perimeter for hours and looks to continue doing so. As a result, looks like we will get little rain in the city today.
ReplyDeleteFor September, tomorrow's thunderstorm setup actually doesn't look too bad. The potential will be thanks to a cold front. With moderate moisture and upper-level winds, some storms will be possible with the potential for an isolated severe storm.
ReplyDeleteI see some dark clouds to the south, looks more rain.
ReplyDeleteThere is the risk for a thunderstorm mid to late evening in Winnipeg today. Not a major event by any means, but better than nothing for September I suppose. An isolated and brief severe storm is possible, but widespread severe weather is not expected.
ReplyDeleteBased on how things are going so far, chance is looking good there will be storm activity in the RRV this evening.
ReplyDeleteI woild not say so, its been for the hole day, inless it clouds over (hope not) then storms is a no.
DeleteI agree although it is humid and sometimes if it is humid and not cloudy you can get thunderstorms , usauly not.
DeleteGood point Wilber.
DeleteIts geting windy a bet the storms are coming. yippee i love storms.
ReplyDeleteCan you you please stop imiting me and a butch of other people. JJ did not make this blog for people to troll it and imitate other intelligent people who comment on this blog for good reason. Please stop.
ReplyDeleteOF course the split scenario came true again in Winnipeg this evening with storms to our north/northeast and west/southwest with a hole in the line right over Winnipeg. These situations are getting to be too predictable if you ask me...
ReplyDeleteI went to go see the storms west of the city this evening with some friends... BETTER than nothing we could say! Lightning was surely the highlight with some fairly good strokes.
I think Winnipeg has a better chance at a thunderstorm today. For once we're not stuck in the rain shadow of Lake Manitoba as the wind is more northerly instead of northwesterly. Could see a few cells creep in or near the city this afternoon from the Interlake.
ReplyDeleteActually, looks like instability is moving off to the east. Thunderstorm potential is thus moving off to the east as well. Some showers, heavy at times locally, are still possible.
