The first 20°C of the year occurred on April 11 with a high of 22.1°C at Winnipeg Int'l A. This was just over a week earlier than the normal of April 20 and just under a month earlier than in 2013 and 2014. In total, 6 days exceeded 20°C in April, slightly above the normal of 4 days and the most since 2010.
An early spring combined with drier than normal conditions to produce blowing dust on windy days through April. April 15 will be remembered well for this when wind gusts over 80 km/h produced significantly reduced visibility in blowing dust outside the city. Winds also caused damage with some broken windows, ripped shingles and other damages reported on social media. That same day, record highs occurred. Winnipeg Int'l A reached 24.8°C, breaking the old record of 24.1°C in 2006.
Another burst of warmth occurred at the end of the month with highs in the mid to high 20's. A high of 27.4°C on April 30 was the warmest in April since 2001. Trees finally began budding during this late month warm spell as well.

The warmth continues for now...
For today, lots of sunshine and highs in the mid 20's. Winds will be from the south-southwest at 20 to 30 km/h.
Tomorrow will feature the peak of the warm spell with highs approaching 30°C in the Red River Valley. Highs will depend on how quickly cloud increases in the afternoon. Areas closer to the US border that manage to remain quite sunny for part of the afternoon have the potential to hit the 30°C mark. 30°C might be a stretch for Winnipeg, but highs around 28 to 29°C are possible. I will provide an update tomorrow morning. Isolated thunderstorms will be possible in the afternoon. Due to low moisture levels, high cloud bases are expected. Strong winds will be the main threat with locally strong wind gusts and reduced visibility in blowing dust possible near thunderstorms.
Mild conditions continue for Sunday and Monday with highs not far from 20°C.
Models hint at a stronger system sometime mid-late next week which could bring some significant rainfall. Too early for specifics.
