Southern Manitoba is in for a very hot day today, possibly what may feel like the hottest day of the summer to date. An influx of warm and very humid air will move into the province throughout the day as an approaching low pressure system will pull warm air up from the south.

Daytime highs will range from 30 to 34 degrees, with the warmest temperatures in the southwest. Couple that with very high humidity today, and the Humidex, or what our body perceives to be the temperature around us, will feel like 35 to 40 degrees.

The heat and moist air, combined with a cold front expected to slice its way through the province today as well, will also make the recipe perfect for storms to develop.  However, C-MOSS Accredited Weathercaster Chris Sumner stresses there is one very big factor working against the development of Severe storms today, and that's something called the 'cap'. The 'cap' is a warm layer of air in the atmosphere, that prevents the convective development of thunderstorms.

"If that cap breaks, then yes, we will have a potentially serious situation on our hands with all severe weather threats on the table including tornadoes," said Sumner. "If it doesn't break, then it will be simply a very hot, very humid day... perfect for sitting on the deck."

Even though the risk of severe weather is only a potential risk at this point, Sumner says it's still important to be prepared.  "The general guidance right now is, again, if the cap breaks and thunderstorms do develop, it will be late this afternoon and early into the evening hours," said Sumner.  "Another caution to throw out there is if these storms start, they will develop very very quickly, so being aware of what's going on around you, and staying up to date on watches and warnings, especially if you are outdoors later today, will be very important."
