Air quality better; burning ban lifted

Air quality improved overnight as a weak weather system stirred up the atmosphere, helping ventilate some of the wood smoke that had accumulated over Spokane by Monday morning. Monday’s burn ban was lifted late this morning. National Weather Service forecasters said the weak storm system is bringing a slight chance of snow to Northeast Washington as far south as Spokane and northern portions of North Idaho through 10 a.m. This morning’s temperatures were an improvement over recent days with 34 degrees reported at 7 a.m. at Spokane International Airport. The high today in Spokane could reach 46 and some sun may show through after the threat of precipitation passes about 10 a.m. Light southwest winds are likely later today. The Spokane Regional Air Agency lifted a code red burning ban for all fireplaces, stoves and wood burning devices, even those that are certified to produce less pollution. The ban came Monday after the Spokane region saw smoke levels climb to the upper end of the moderate range with an air quality index of 88. A level of 100 is considered unhealthful for sensitive persons and people with health problems. This morning’s air index stood at 41, less than half of Monday’s level and in the upper end of the good range of 0 to 50. The burning restrictions were re-evaluated today, allowing the clean air agency to lift all burning restrictions. Forecasters said they are concerned that pollution levels could build again through Friday as a system of higher pressure comes over the region. Sunshine is likely to be seen on Wednesday and Thursday before clouds gather in advance of a potent weekend storm that should bring rain. Highs will go back into the lower 50s with lows in the upper 20s to lower 30s.
