Although a storm that swept through Brandon this morning just before breakfast appears to have passed, Environment Canada is warning of very variable weather for Westman through most of the weekend.
To blame is a persistent weather pattern setting up over western Canada, sending several days of unsettled weather through western and central Manitoba.
In general, bands of showers and thunderstorms will develop over the northern U.S. and track into western Manitoba, stretching from the Saskatchewan border to the edge of the Manitoba escarpment.
So far today
Ag-weather stations across Westman reported highly variable amounts of precipitation from Friday morning's storm. As of 8 a.m., the following rainfall amounts were reported this morning:
- Birtle — 5.9 mm
- Boisevain — 3.7 mm
- Deloraine — 26.6 mm
- Forrest — 31.6 mm
- Glenboro — 1.4 mm
- Hamiota — 6 mm
- Killarney — 0.7 mm
- Minnedosa — 6.8 mm
- Reston — 13.8 mm
- Russell — 5.5 mm
- Souris — 11.7 mm
- Virden — 28 mm
- Wawanesa — 0.6 mm
The next bit of unsettled weather is expected to develop this afternoon and persist well into the evening. Thunderstorms are expected to again develop first in southwestern Manitoba and then spread eastward and northward through the evening.
Rainfall amounts will be highly variable from location to location, as the track of the individual thunderstorms may drench some areas and leave others mostly dry. In general, another 5 to 10 mm is expected in many areas with Brandon expected to get 10–20 mm and a few locations once again seeing upwards of 25 to 50 mm from intense thunderstorms Friday night.
The high today will be 25ºC, but the storm systems will bring winds as well, with southeasterly winds at 30 km/h gusting to 50 km/h this morning, and then switching around to 20 km/h late this afternoon.
Winds will finally die down late this evening, as temperatures drop to a low of 15ºC.
Cloudy skies continue tomorrow, with a 60 per cent chance of showers later in the afternoon and evening, along with the risk of a thudnerstorm. Tomorrow's high will be 23ºC.
Sunday will see showers, with a high of 23ºC. Monday, too, will be wet, with showers throughout the day. It'll be cool on Monday, too, with a high of just 18ºC.
Holiday Tuesday will see a bit of a break from the rain, with a mix of sun and cloud for Canada Day. But you'll want to take a jacket anyway, the high will be 18ºC.
Further into the truncated week, the extended forecast for Wednesday and Thursday calls for sun, with temperatures approaching normal, in the low- to mid-20s.
The normal high for this time of year is 24ºC; the normal low is 12ºC.
The hottest it's ever been on this date was in 1961, when it hit 35ºC. The coldest ever was in 2000, when it was 3.8ºC.
