Next threat of thunderstorms moves into RRV Thursday evening
A trough of low pressure moving across southern Manitoba Thursday is forecast to produce an area of showers and thunderstorms over southwest MB by afternoon, likely spreading into the Red River valley by evening before weakening east of the valley Thursday night. The storms are not likely to be that severe owing to the lack of strong wind shear, however adequate moisture and instability will likely trigger a few strong storms with a slight risk of nickel size hail. More likely, the storms will produce locally heavy rainfall with local amounts of 25 to 50 mm possible, especially over western MB into the Interlake region. This band of showers and thunderstorms will gradually push through the Red River valley Thursday night into Friday, with a gradual drying trend by Friday afternoon. More unsettled weather with showers and thunderstorms is expected Saturday night into Sunday over the RRV, with a potential for some locally strong to severe thunderstorms.
