Supper hour storm makes it three in one day on Friday

Posted by Adam in Local Weather, 9/20/2019

Mother nature is clearly not a happy customer in Westman today. 

Just hours after a pre-dawn severe storm brought heavy rain, intense lightning and up to loonie-sized hail to Brandon the city was forced to batten down for rounds two and three on Friday. 

A storm that passed over just after 2pm resulted in Environment Canada issuing its second Severe Thunderstorm Warning of the day for the city. Primary threats to that particular event were a handful of loud booms and additional heavy downpours within. 

After a period of relative calm with a little more rain sprinkled in for good measure a third fast-moving separate storm passed over the city from the Southwest beginning at approximately 5pm and lasting for less than half an hour. Initial accounts point toward the evening’s main threats having been a torrential downpour with its share of thunder and lightning. Though a severe thunderstorm watch had been in place at the time, no severe storm warning accompanied the third event for Brandon despite the same system being severe-warned for Souris. 

Prior to round three Environment Canada had placed Brandon as having received 25-35mm of rain on the day through 4pm. Unofficial data via eBrandon’s rain gauges placed the third storm as having brought an additional 7-10mm. 

Runoff areas like this 18th St South ditch were put to the test by the end of storm #3

Though no additional storms appear imminent as of the time of this posting Brandon remained under a severe thunderstorm watch with Environment Canada’s hourly forecast calling for a high likelihood of showers or thunderstorms through the 9pm hour. All watches at warnings can be monitored at this link.

It’s all made for the most unusual day as the official end to summer draws near. Typically the area receives its most severe weather during the May-through-August period with more moderate storms rearing their head in September. 

As of now the current forecast calls for further thunderstorm risk late in the morning and in the afternoon on Saturday before a return to sunny skies on Sunday and Monday.
