Southern Manitoba will experience a warm da y on the day Thursday with southerly winds ushering in  warm temperatures. Also temperatures on Thursday will rise into the mid to high 20s some areas may surpass 30 Celsius depending on location and daytime heating. The red river valley areas towards the international border are more than likely to experience daytime temperatures in the high 20s ahead of the cold front .

With the heat and humidity that’s in place instability will increase   MUCAPE values reaching 1,500 to 2,500 J/KG. A cold front will enter this unstable airmass in the late afternoon to early evening promoting thunderstorm development likely NW Of this city of Brandon travelling east south east throughout the remainder of the evening hours entering the red river valley by around supper time to 9 PM.
