Seasonably warm weather to close out July.. but 30C heat continues to elude Winnipeg
It will be a nice warm week ahead with high temperatures generally in the mid to upper 20s over the RRV and southern MB. Conditions should be generally dry as well with little in the way of showers or thunderstorms expected through Friday. The next threat for organized showers will be on Saturday as a weak frontal system slides through southern MB. The greatest heat through the end of the month however will still be focused out west over SK and AB which have experienced multiple days of 30C or more this month. In Winnipeg, we have yet to hit the 30C mark in July, even though precipitation has been below average and sunshine has been plentiful. The upper pattern this month has brought the bulk of the heat over western Canada with cooler temperatures over eastern Manitoba into Ontario. There is a chance Winnipeg may be close to the 30C mark by the end of the week. Since 1872, there have been 12 Julys in Winnipeg that have failed to reach the 30C mark, most recently in 2009. With one week to go, we'll see if July 2017 is added to that list.

Coolish Canada Day 150.. but then heat builds for first half of July over Prairies
Happy Canada Day! Canada is 150 years old today, founded back on July 1st 1867, and celebrations marking the milestone event will be held throughout the country. In southern MB, skies on Canada Day will likely start off cloudy as a disturbance tracks across southwest MB into North Dakota tonight into Saturday. This system will spread a few showers across SW Manitoba tonight and into the Red River valley overnight into Saturday morning. The bulk of showers will likely be mainly south of Winnipeg, but there is the chance the city may see some showers Saturday morning. The system should be out of southern MB by midday leaving a mix of sun and cloud Saturday afternoon along with a northerly breeze of 20 km/h. Temperatures will be on the cool side of normal with highs around 21C, a few degrees shy of the average of 25C for July 1st, but quite comfortable for outdoor activities. There is the chance of some isolated showers popping up Saturday afternoon with daytime heating, but most areas should be rainfree for Canada Day festivities. Skies will be clearing by Saturday evening, with ideal conditions for fireworks at 11 pm.. although a little on the cool side with temperatures near 15C by that time. The rest of the holiday weekend is looking good with sunshine on Sunday and highs of 24C and 27C by Monday under partly sunny skies and increasing southerly winds.
