After a sizzling Sunday, it's a meltdown Monday as the hot and humid airmass persists over southern MB. As of 11 am, humidex values had already surpassed the 40 degree mark over many localities thanks to some very high dewpoints today.. including an unbelievable 28C dewpoint reading at Carman. (I suspect this value is erroneously high, as the dewpoint at Carman always seems to be a couple of degrees too moist compared to neighbouring sites.) Nonetheless, dewpoints across southern MB are in the 22-25c range today which will make today's 35C temperatures feel oppressive. Take it easy out there.
By the way, I replaced the barometric graph plot on my main page with a dewpoint/heat index plot to better gauge how sticky it is over the next few days.
