Saturday will start off humid and quite warm for most, our high temperatures will quickly budge up into the high twenties to low 30's. Factoring in the dewpoints being in the low to mid 20's we will be dealing with a very humid airmass and it will feel oppressive heat will be present in a huge way as humidex's surpass 40C. As a result of the heat and humidity our atmosphere will become extremely unstable based on various models meaning there will be a risk for severe weather throughout the day. Here is how it could play out, a frontal system is expected to slide through southern manitoba during the morning sparking off showers and thunderstorms in areas just to the east of Winnipeg however this will not be the main story for tomorrow's severe weather. Once this systems clears out sunny skies will overtake but the next threat will come in the evening as storms possibly form in Southeast Sask/Southwest Manitoba and merge into a line of storms some possibly severe what I call a MCS (Mesoscale Convective System). The line will likely progress eastwards through areas of southern manitoba through the evening and overnight, likely reaching the RRV and Winnipeg in the late evening. Large hail and damaging winds would be possible along with intense to frequent lightning. I will post details in the thunder storm outlook center, and will update the comments as needed to provide information on the evolving situation.
Storms would clear overnight and then there will again be a potential for storms on Sunday.
Thundery Sunday
Sunday looks like it will be a quieter day weather wise and as a result there won't be severe storms but still a chance for showers and non severe thunderstorms as a cold front slumps southwards our high temperatures will be in the mid to high 20's.
Potentially Stormy Week Ahead
Much nicer weather will return to start our week however there will be multiple storm chances as they return on Monday, Wednesday, Thursday and Friday. High's still in the mid to high 20's.
