The dewpoint of 18.1°C on September 26 was the 4th highest on record for so late in the year. It was also very close to being the highest for so late in the year: a dewpoint of 18.6°C on October 8, 1997.
Only one temperature record was broken however, perhaps because temperature records go back much further, all the way back to 1872. Nonetheless, a minimum temperature of 17.4°C on Friday the 26th shattered the old record high minimum of 14.4°C in 1950. This was also the highest daily minimum temperature for so late in the year.
The heat and humidity on Friday also broke yet another record. A maximum humidex of 35.8 was the highest for so late in the year and the latest occurrence of humidex over 35 on record. A high of 30.2°C was just shy of the old record high of 31.7°C in 1952 and brings our total of 30°C days this year to 8 days. This is below the 1981-2010 normal of 14 days for an entire year.It was even hotter out west, where this burst of late September heat was basically unprecedented for so late in the year. In Brandon, temperatures exceeded 32°C for two consecutive days on Thursday and Friday. Highs of 34.0°C and 32.8°C, respectively, did not only shatter the old record highs, but were also the hottest temperatures ever recorded for so late in the year since 1890. Previously, the latest Brandon ever got that hot was on September 22, 1897 and 1938 with highs of 33.9°C. Humidex values reaching 37 were also unprecedented for so late in the year.
The hottest temperatures recorded last week were 35.1°C in Wawanesa on Thursday and 35.1°C in Swan River on Friday.
Fall-like conditions return today with temperatures remaining steady near 10°C. Periods of rain will continue until this afternoon. 5-10 mm is likely with locally higher amounts possible. Low cloud will likely remain tomorrow, keeping our highs in the low teens. Warmer for Tuesday and Wednesday with highs in the mid to high teens. A system will likely bring some showers Tuesday night into early Wednesday however. We cool down for late week. There is the potential for our first frost Saturday morning, but it's too early to confirm. Just keep in mind the possibility exists.
Quite cloudy today with lingering low cloud, likely keeping our highs around 9-11°C. If we managed to get more sun than expected, we could reach 12-13°C, but I'm not too optimistic that will happen. Sunnier to start tomorrow, but increasing cloud in the afternoon with showers likely in the evening. Highs in the mid teens, perhaps high teens if we got enough sun. It will be breezy out of the southeast as well.
ReplyDeletePeriods of rain tomorrow night, ending Wednesday morning. Not expecting high totals with this, likely only 5-10 mm at most. Depending how much sun we get Wednesday afternoon, could see highs getting close to 20°C.
More significant cool down arrives on Friday with highs likely remaining in the single digits.
Wow, it has been a major struggle to get a real extended period of above normal temperatures in 2014. Now that we are near the end of the year, it seems things haven't changed. Unfortunately, it doesn't get any better as all signs point to a below normal October. November and December will probably follow the same theme meaning this may go down down as one of the worst weather years especially in recent memory. And too make matters worse, there are more and more rumblings that yet another cold and snowy winter is on tap for us as the now expected very weak el nino is likely not to be a major factor.
ReplyDeleteYikes, clouded up earlier than expected today. Doesn't look like we'll see much, if any, sunshine at all today. Could keep our highs a little lower than they could have been. Showers at times this evening through to tomorrow morning. Looks like bulk of the rain may stay to our west, so only expecting up to 5 mm here. Doesn't look like we'll clear for the afternoon, so that'll also keep our highs lower than they could've been. So far, looks sunnier to start on Thursday, which should allow for highs in the high teens. Clouding up in the afternoon as another weak system moves in. Chance of showers later in the afternoon and evening. Scattered showers to continue on Friday. Big cool down also starts on Friday, with highs only in the high single digits at most.
ReplyDeleteAt this point, it appears the cold will continue through the weekend and through all of next week. This will likely mean frequent chances for our first frost of the year, starting on Saturday. Can't rule out our first snowflakes of the year coming next week as well, considering how cold we'll be. I don't see any evidence of accumulating snow just yet however.
Low cloud beginning to break up in southeastern Manitoba and the RRV this afternoon, so thankfully not a complete downer of a day. Will cloud up again later in the day as that system approaches.
