KEENE, N.H. (MyKeeneNow) Smoke from wildfires burning in Canada will continue to create hazy skies across the Monadnock Region through Thursday, while warm temperatures remain in the upper 80s.

The New Hampshire Department of Environmental Services has issued a smoke advisory as fine particle pollution drifts into the state from large wildfires burning in central and western Canada. The smoke has given the sky a yellow-orange tint across much of New Hampshire and is expected to continue affecting air quality through at least Thursday.

Wednesday’s forecast for Keene calls for widespread haze and partly sunny skies, with a high near 87 degrees. Overnight, skies will become mostly clear, although patchy smoke is expected after midnight as temperatures fall to around 63 degrees.

Smoke will linger into Thursday, with patchy haze possible throughout the day despite mostly sunny skies. High temperatures are expected to reach 87 degrees again, with west winds increasing to 5 to 10 mph and occasional gusts up to 20 mph. Any remaining smoke should begin clearing Thursday evening as overnight lows dip to around 59 degrees.

Environmental officials say the smoky conditions have reduced air quality across the Granite State. People may notice the smell of smoke and experience symptoms such as coughing, shortness of breath or chest discomfort.

Health officials recommend that people who are especially sensitive to air pollution—including older adults, young children and those with heart or lung conditions—as well as healthy individuals, limit prolonged or strenuous outdoor activity while the advisory remains in effect.

Forecasters expect the smoky conditions to gradually improve by the end of the week as the wildfire plume shifts away from New Hampshire. Cooler, more comfortable weather is expected to arrive Friday and continue into the start of the weekend.
