Warm westerly wind prompted a yellow-level wind warning in southern Alberta early Tuesday. Environment and Climate Change Canada explained, “Strong west winds gusting to 100 km/h will continue this morning. Winds will weaken by this afternoon.” By 9 a.m., wind gusts around 70 km/h were recorded around Pincher Creek and Lethbridge with gusts near 50 km/h in Calgary. Temperatures were elevated early in the morning with many weather stations around Calgary showing values around 12 C to 14 C. A typical morning temperature for the area this time of year would be 1 C to 3 C. Yellow-level rainfall warnings have been issued for the southern B.C. coast and that same system is expected to continue pulling moisture toward the Rockies. Rain and mixed precipitation were observed between Highway 1 and Highway 3 in southern British Columbia overnight and early Tuesday, and precipitation is expected to continue to fall into the evening and early Wednesday. Some light rain is possible on the eastern side of the Rockies Tuesday night and early Wednesday, but if that system does cross over Calgary, the totals would be minimal. A low-riding jet stream will allow cooler air to flow west to east along the southern half of the western prairies on Wednesday and Thursday which will lower the temperatures. Daytime highs in Calgary will peak at 13 C on those days before returning to the mid-teens by the weekend. By Monday, daytime highs should return to the high teens to low-20s and stay there until the middle of next week.
