Today will start out sunny, but thunderstorms to follow will set the tone for the next few days.
Environment Canada says Brandon can expect sunny skies until about lunchtime, with increasing cloudiness after that, and a southerly wind picking up, at 30 km/h. The high will be 24ºC, but the UV Index is expected to only hit 6, although that's considered high.
There's a good chance of showers or thunderstorms this afternoon and this evening, although the rain should taper off near midnight, as the wind dies down, and skies will clear after that. In total, expect 10–15 mm of rain, but thunderstorms could bring as much as 25 mm in some areas. The overnight low will head to 12ºC.
Tomorrow will dawn sunny, but like today there will be more clouds as the day goes on, and a good chance of showers or thunderstorms late in the afternoon and in the evening. Southwest winds are expected at 20 km/h late in the afternoon, swinging around to the northwest, and picking up to 30 km/h late in the evening. Tomorrow's high will be 24ºC.
Sun is predicted for Friday, but in the wake of the storms, the temperature will be dramatically lower, with a high of just 16ºC to close out the work week.
The weekend looks cool, with a high of 18ºC on both Saturday and Sunday. There will be sun on Saturday, but clouds roll in for Sunday and there's a chance of showers that day.
At this point, it looks like the start of next week will see Monday with a mix of sun and cloud, and a high of 22ºC, followed by clouds and probable showers on Tuesday, along with a high of 21ºC.
The normal high for this time of year is 22ºC; the normal low is 10ºC.
The warmest it's ever been on this date was in 1988, when temperatures were 35.8ºC. The coldest ever was just the next year, in 1989, when they dropped to 0.8ºC.
