Colder weather on tap..
Colder weather is on tap over southern Manitoba for the next few days as a cold northwest flow sets up behind a storm system intensifying over northern Ontario Thursday. This system will drag the coldest air of the season so far over southern Manitoba, with daytime highs only near or slightly above freezing, some 5-7C below normal for late October. The cold weather will be accompanied by mainly cloudy skies and occasional flurry activity, with locally heavier snow bands possible to the southeast of Lakes Winnipeg and Manitoba. The cold weather is expected to persist through the weekend into early next week, with a moderating trend possible later next week.

Is the 15 month above normal streak gonna be over?ReplyDelete
Yes it will be. We're right on normal right now (5.3c) but we're going to lose a few tenths of a degree over the next few days. It was quite the run though...ReplyDelete
Quite the cold snap in Alberta... Calgary hasn't rose to the freezing mark since Saturday and is not expected to until at least Monday... The 24 cm of snow that has fallen there since the weekend is not melting much I'm supposing. Some ski resorts are opening in the next couple days, apparently the earliest start ever.ReplyDelete
And on the other hand, Windsor recorded a humidex of 28C (temperature of 24.1C) yesterday along with a LOW of 15C.ReplyDelete
They still haven't froze this year.
Jeez, Welland-Pelham in the Niagara peninsula recorded 25.3C today!ReplyDelete
Several places in Ontario also had a humidex up to 28C.
All this while it's snowing in Kenora...
Welland.. my hometown! They still have leaves on the trees down there too. All downhill after today though as a cold front goes through later today followed by the approach of "Frankenstorm" early next week!ReplyDelete
Southern Quebec's turn to taste the heat...ReplyDelete
Huntingdon, Quebec recorded 24.5C today, the warmest spot in the country.
They also had a humidex of 27C which is quite possibly the last humidex reading we'll have in Canada this year.
with October likely to finish slightly below normal, can we expect much of the same for November in terms of below normal temps?
I see, it looks like we'll finally see some sunshine next week and a welcomed break from the precip, are there any signs of this wet pattern this month continuing through November?
Anybody in more northern parts of the city have a snow measurement of what fell last night? Only got 0.4 cm here in south end, but looking at radar it looks like there was more in central/east/north parts of city.ReplyDelete
On the north side I have nothing scientific but I would say approx 1.5cm of very fluffy snowReplyDelete
Sorry for the lack of input lately... weather's kind of dull here and I'm following the big weather story out east (Sandy) with great fascination. Will be a very interesting 24-48 hours coming up..ReplyDelete
Anonymous.. I don't see much in the way of big cold snaps or storms over us for the next week or so. Temps should be generally near normal for the first part of November. But after that, it's too tough to say how November will play out.. no real clear signals one way or the other at this point.
Wreckhouse, Newfoundland recorded 22.6C today... with a humidex reading reading (25C) for an hour.ReplyDelete
Amazing warmspell in the East before Sandy!
Pressures are dropping like crazy!!!ReplyDelete
Lowest I've seen so far is 976 mb in Wildwood, NJ.
For Canada, lowest so far is 100.7 mb at a couple of places in Eastern Ontario.
BTW-Canadian all-time low is 940.2 mb in St Anthony, Newfoundland during a winter storm on January 1977.
Eye approaching southern NJ coast... Atlantic City down to 958.7 mb as of 20z, a drop of 6 mb past hour!ReplyDelete
Atlantic City down to 952.4 mb!!!!ReplyDelete
Oh I didn't know Winnipeg 'A' CS station took snow depth measurements. I see 1 cm depth was reported last Friday. Are these measurements official or are yours official Rob?ReplyDelete
The snow depth obs from YWG "A" station are automated observations from a sonic snow sensor that uses sopund waves to estimate the snow depth. Prone to error, but they are entered as obs in the climate database.ReplyDelete
I take snowfall observations from my climate site in Charleswood (since 2004), and those are considered official snowfall obs for Winnipeg.
Officially, Sandy made landfall about 5 miles south of Atlantic City at 8 pm with a minimum pressure of 946 mb. ECMWF was the clear model winner on predicting this storm's evolution several days out, with the other models eventually catching on. Make no mistake about it though, models overall did an incredible job predicting this system days in advance.. in its evolution, its intensity and its track. I continue to be amazed how accurate these models can be..ReplyDelete
Point Petre, Ontario pressure is now down to a 98.9 kPa...ReplyDelete
Well... lowest pressure I saw overnight was Long Point at 98.3 kPa.ReplyDelete
Geez Edmonton (Int'l) has not been above zero since two Saturdays ago (10 days) and not expected to rise above zero until at least this coming weekend. Ground in Alberta has been snow covered for about 10 days now too. Now that's an early winter! Doesn't feel so bad here now!ReplyDelete
Downtown Montreal recorded 22.1C today! Highest in the country.ReplyDelete
Low of 14C over there as well...
Actually only 13 stations in Canada were above 20C today and they were all in Southern Quebec (warm side of Sandy).
Weather network is calling for 5 cm snow Friday. Is this really a possibility?
Actually downtown Montreal was not the warmest spot in Canada...ReplyDelete
Saint-Hubert on Montreal's south shore recorded 22.4C. Pretty impressive for Halloween in Canada.
We have a weak Alberta clipper crossing southern SK Friday spreading an area of snow over southern MB, over SW MB before dawn reaching Winnipeg/RRV by midday. Models bring about 3-8 mm of liquid pcpn, which would work out to about 5 cm of snow with a little melting. So yes, some accumulating snow definitely possible Friday, especially Friday afternoon/evening for Winnipeg. Current forecast of "Mix of sun and cloud" for Friday fails to capture this possible snow event.
