An upper-level trough moving over Western Canada brought some unsettled weather to British Columbia this week, a welcome change from the relentless heat and dry conditions that have dominated the region this summer. While the trough will soon move east, more moisture could spread over southern B.C. by the end of the week. More on the rain chances and ongoing wildfires, below.
TUESDAY: SHOWERS LINGER IN THE INTERIOR
Scattered showers will continue across the B.C. Interior on Tuesday as an upper-level trough moves through the area. The best chance for accumulating rain exists near the border with Alberta, where spots could see an additional 5-10 mm of rain through the end of the day.
While any rainfall is welcome for areas dealing with wildfires, totals won't be nearly enough to put a stop to the ongoing blazes.
Temperatures will remain in the lower 20s across southwestern B.C., with highs in the upper teens likely in southeastern B.C. where clouds and rain help keep temperatures down a bit.
WEDNESDAY AND BEYOND: DRY CONDITIONS RETURN BEFORE RAIN CHANCES THIS WEEKEND
A ridge building behind the trough will allow conditions to dry out once again across B.C. We’ll see temperatures around seasonal for the remainder of the week.
Moisture will return by this weekend, bringing several opportunities for showers and thunderstorms across southern B.C.

POOR AIR QUALITY FROM ONGOING WILDFIRES
Hazardous air quality is still an issue across parts of the B.C. Interior, especially for communities near large wildfires. Fires continue to burn across the province despite the cooler temperatures and the recent rainfall.
The rain will help to clear out some of the smoke, improving air quality somewhat. However, special air quality statements remain in place for the Interior. Northerly winds will blow wildfire smoke into the valleys.
"During a wildfire, smoke conditions can change quickly over short distances and can vary considerably hour-by-hour," says Environment Canada in the air quality advisory.
As of Tuesday morning, there are 263 fires burning throughout the province, mostly in the Interior. The province has seen more than 1,500 fires so far this year, which is more than double the total number of fires we saw in all of 2020.
