Though poor quality air continues to hang over the D.C. region on Tuesday, there may be relief in sight.
Though nowhere near as dense as the smoke that prompted last month’s unprecedented health alert, an unmistakable brownish haze continues to linger over downtown D.C.’s monuments Tuesday.
On Monday, air quality levels dropped to a Code Orange alert as smoke began to roll back into the region from ongoing Canadian wildfires. Air quality improved to between Code Orange and Code Yellow Tuesday morning, where it still sits around 80 AQI Tuesday afternoon.
A slow-moving cold front is approaching the D.C. region, which is expected to bring a southwesterly wind and a chance for a pop-up afternoon shower or storm, as well as improved air quality, according to 7News meteorologist Eileen Whelan.
A couple of storms could also bring damaging winds and hail.
“As we head through the latter half of the day, one or two storms could fire off, nothing too widespread but if that does come together, it could pack a punch with some heavier rains and gusty winds,” van de Graaff said.
