Thankfully, a Colorado Low south of the border looks to remain to south and east over the next couple days. As a result, there are no worries of snowfall here in Winnipeg. However, this does not mean we wont feel any effects of the system. Moderately-strong north/northeasterly winds today and tomorrow will draw in much more fall-like temperatures. In addition, today will be fairly cloudy.
For today, it will be a cloudy one. Other than perhaps a couple breaks in the cloud here and there, it doesn't look like we'll see the sun much today if at all. Temperatures will only reach the high single digits with a high of 9°C anticipated in Winnipeg. North-northeasterly winds between 20 and 30 km/h are expected with gusts to 40 km/h at times.
The sun returns tomorrow as the Colorado Low begins to move further away. After a mix of sun and cloud in the morning, the afternoon looks fairly sunny. We should see temperatures rise to the low teens with a high of 11°C expected in Winnipeg. It is of note that frost will be likely in southwestern Manitoba Saturday morning as temperatures dip to between -1°C and -4°C. This frost may get as close as the western RRV. Here in Winnipeg there may be some patchy frost, but it doesn't look widespread at this point.
A better chance for frost exists in Winnipeg on Sunday morning. Lows between -1°C and -3°C are expected. This will be the city's best chance for frost so far this season and this could end the growing season inside the city. As for the afternoon, it looks fairly pleasant. We should see a mix of sun and cloud with highs reaching 14 to 15°C.
Early indications point at a mild week next week. If these indications are correct, we may see another day or two of temperatures near 20°C. Hopefully this trend continues!
