Forecast Discussion

Hourly ozone levels have temporarily risen into the low Code Yellow range but should quickly fall as clouds increase and solar radiation decreases. Fine particulate levels are in the low Code Yellow range across most of the state.

Monday into Tuesday, a weak backdoor cold front will attempt to push in from the north. If successful, a colder and drier air mass will advect in that should lower air quality levels back into the Code Green range statewide. A weak upper disturbance will rapidly approach from the west that could spark some showers as well. Fine particulate levels will likely hover in the upper Code Green to low Code Yellow range, while increased clouds and showers should easily hold ozone levels in the Code Green range.

Wednesday, an upper level ridge axis builds overhead, which should result in less clouds and light southerly surface flow. Given the time of year, can only expect that continued prescribed/agricultural burns to the south will result in smoke and elevated fine particulates to begin working back into the region, which will result in both ozone and fine particulate levels rising.
