It will be another hot one for Manitoba today as temperatures rise into the low thirties, and dewpoints in the high teens and near twenty. This will bring humidex values close to 40 later this afternoon and early evening if you are not under a thunderstorm. It will be one of those days where strenuous activities outdoors should be reduced, and everyone should keep hydrated outdoors. Seeking shade if you have to be outdoors is a great idea.Today will also be a watch-the-sky type of day as severe thunderstorms will be possible throughout southern and central Manitoba this afternoon and evening. Severe thunderstorm watches have already been issued by Environment Canada this morning for all of southern Manitoba, excluding only the Virden and Melita areas. Large hail and damaging winds will be possible. A small risk of tornadoes exists in the Interlake due to lake-breeze convergence, and in south-central/southwestern Manitoba. Winnipeg's best risk for storms will be late afternoon and evening.
Behind these storms, it will be a cooler and drier day tomorrow with highs in the high twenties, and humidity low.
Things heat up again Tuesday. Highs in the low to mid thirties will be possible, however it will be a drier heat. Humidex values are ''only'' expected to be in the mid to high thirties.
Working on a thunderstorm forecast update, will have it ready soon.
ReplyDeleteMy update is ready, go in the Thunderstorm Forecast tab for the update. I will continue to update it as necessary.
ReplyDeleteWow, the temperature just keeps getting higher and higher! 35°C in the city now, the hottest day since August 2011.
ReplyDeleteOld record today is 36.1°C back in 1939, so I don't think we'll break it.
ReplyDeleteSevere thunderstorm warning for Winnipeg. Batten down the hatches! It would be a good idea to secure items outside, as this could be a good windstorm. Gusts of 120 km/h have been seen with this line heading for the city.
ReplyDeleteThunderstorm risk is now over for us for tonight. Wow, what a storm earlier! Winds gusted to 98 km/h at Winnipeg airport, and there are unconfirmed reports of 150 km/h gusts to the north of the city in the Interlake. Lots of damage throughout southern Manitoba, including in the city of Winnipeg. Uprooted trees, lots of twigs and branches on the ground, and other damages being seen. Even a report of a house levelled near St. Laurent. Likely was not a tornado, and rather a result of plow winds near 150 km/h possible.
ReplyDeleteThere could be some severe thunderstorms in southwestern Manitoba tomorrow. All the ingredients - shear, moisture, low-level winds, instability, trigger - are all there. However, there is a negative about tomorrow; and that is the cap. The cap is expected to be quite strong tomorrow, which could prevent any storms from developping at all. But if a storm does break the cap tomorrow, it would have good chances of becoming supercellular with the potential for tornadoes.
ReplyDeleteDefinitely something to watch tomorrow...
It could be another severe weather outbreak in Manitoba today. Today's threat covers many of the areas worst hit by Sunday's outbreak, so today could potentially only add insult to injury. Will keep you all updated. Main threat today is vicious winds, just like Sunday.
ReplyDeleteWill have my thunder forecast up later this morning, along with a new post.
