Hot and more humid conditions will spread over southern MB today ahead of a trough of low pressure through Saskatchewan. Afternoon temperatures will reach the low thirties with dewpoints climbing into the uncomfortable low 20s today. This will send humidex values close to the 40C mark this afternoon across the RRV, and thus a humidex advisory has been issued for the area including Winnipeg. The big question is what will happen later this afternoon into this evening as the frontal trough approaches from the west. This trough will encounter the hot and humid airmass over southern MB to trigger some scattered thunderstorms later today.. some of which may be severe with heavy rain, hail and strong winds possible. There is even a risk of isolated tornadoes with any discrete supercells that develop. At this point, the best chance for convective development will be over the RRV, and SE MB into ND.. but hopefully, some weaker storms fire up in the RRV to give us some much needed rainfall. Will we miss out again, or will we finally see some rain today? Stay tuned..
