Whew.. it's a sweltering one out there today. As of 2 pm, my weather station is showing 29C with a 23C dewpoint giving a humidex of 39C. Very uncomfortable. (A trick to estimate humidex.. add the temperature and dewpoint in C, then subtract 13). Even more oppressive down to our south with Emerson checking in with a 42C humidex as of 2 pm (temp 32C dewpoint 23c) The hot and humid airmass will trigger a few thunderstorms this afternoon as a cold front approaches from the northwest. A few of thes storms may become severe, with large hail and damaging winds being the main threats. Isolated tornadoes are also possible given the extreme instability today. EC has issued a severe thunderstorm watch this afternoon for much of southern Manitoba including Winnipeg. Stay tuned and keep an eye to the sky if you're out and about today.

Front went through Winnipeg just after 4 pm.. but it was dry. No thunderstorms or showers.. just a wind shift into the north, and a noticable drop in temperature (from 31 to 26 in one hour). I guess it was too warm aloft to get anything going..ReplyDelete
