Heat and Humdity Persist, ongoing chances for showers and thunderstorms.

This Blog will be a little bit shorter as I have some things to work on this evening, once again our region pretty much all of southern Manitoba is dealing with significant heat. A large ridge of high pressure and a strong southerly flow over southern Manitoba will aid in high humidity values this weekend. Saturday expect high temperatures to rise into the low to mid 20's, humidity values will rise into the mid to high 30's. The same boat is in store for the day on Sunday where daytime high temperatures will again rise into the high 20's and low 30's, for much of our area with the humidity making it feel more like the mid to high 30's as dewpoint values rise into the high teens. There will be a chance at showers and thunderstorms with not everyone seeing rain and heavy rainfall, the higher risks will be in western Manitoba where a persistent low pressure system will sit in southern Saskatchewan so in that part of the province there may be a higher risk for severe thunderstorms on the day Saturday and Sunday. There will also be a risk for thunderstorms as we go into Sunday evening as well. Points show a cold front slicing into that hot humid airmass in the afternoon on the day Sunday. I dont have a lot of details other than that a risk for severe weather may present itself on Sunday in the interlakes and the red river valley well into southwestern Manitoba as the CAPE values surpass 1,000 to 2,000 J/Kg. Overnight lows for saturday and sunday night will only drop into the low to mid 20's. 

The Week Ahead: Significant heat will continue into the week, however more unsettled weather will be likely as a trough and shortwave move through heat and humidity with highs in the high 20's and low 30's. Overnight lows still in the high teens and low 20's. The upper trough by the start to the middle of the week will increase a risk for thunderstorms and possible severe thunderstorms. I should know more by the end of the weekend. 

Stay cool! A full in detail blog will be back on the day on Monday!
