Thunderstorms did materialize across parts of southern Manitoba overnight and this morning. The bulk of the storm activity occurred in the Whiteshell area east of Winnipeg and also in southwestern Manitoba. Multiple waves of thunderstorms have been and are occurring so far today in the Brandon area with 25+ mm recorded so far, including about 32 mm in Forrest and Virden according to Manitoba Agriculture.
Thunderstorm activity is expected to continue through the night for parts of southern Manitoba. Additional thunderstorm activity is likely tomorrow, especially over central and eastern parts of southern Manitoba. Main threat will again be flooding rains. Winnipeg's best shot for thunderstorm activity will be tonight and tomorrow.
We do not dry out for a while. Scattered shower activity remains possible Sunday through to Canada Day Tuesday. Thunder is possible on Sunday but not very likely Monday and Tuesday. Temperatures will be quite cool Monday and Tuesday as well, likely only reaching mid to high teens. Drier weather returns by Wednesday and temperatures should warm back up late in the week.
