| A Powerful upper level ridge will once again build in over our region |
A powerful upper ridge will make it's way into Southern Manitoba over the next 12 hours. As a result heat will start cranking up in the southern half of the province and could last 3 days at the most. Tonight winds will shift to the south with most temperatures remaining in the high teens for overnight lows. The southerly wind will help clear the air of any leftover haze or smoke that has been hovering around. That will also aid more solar heating of the atmosphere resulting in cooking temperatures throughout the next 3 days. How hot exactly will it get? Models indicate temperatures of 37 to 40C over areas along the international border, while the temperatures further North towards Highway 1 along and South you can expect temperatures of 34 to 37C. Although I think that 40C might be a bit of a stretch on Thursday considering that it hasn't happened for a long time into history, as well as dewpoints sit in the 20's. With the temperature and the dewpoint combined humidex values will be from 40 to 45C across a widespread portion of the province, some places may even feel closer to 50C. It is near certain that we will see temperatures in the mid to high 30's with humidity values making it feel like the 40's It will definitely be a hot day in the southern half of the province.

| NOAA Wx Map at 00UTC Friday |
Although there will be a potential for some thunderstorms on Thursday afternoon through until 6am Friday in Southern Manitoba as a front slides through, if storms fire along the front they may become severe given the heat and humidity. If nothing fires we will just see sunny skies, but then again there is a risk given the hot weather.
As for things on Friday daytime highs should be closer to 30C and not as hot as Thursday's 30C+ Temperatures. So thing's will feel a little more comfortable given less heat and humidity. As For the weekend hot weather to continue with isolated storm chances.
Get Out There and Cool off with a Slurpee and or a Blizzard!
Oops forgot to mention; Given the high heat and humidity tomorrow Environment Canada may end up having to issue a Humidex Advisory as Humidex values are forecast to surpass 40C. Overall they will likely end up dropping the advisory during the evening hours. Stay Cool!
