FORECAST SUMMARY:
Monday, October 14th, 2019 through Monday, October 21st, 2019
Ozone: 8-hour Ozone concentrations will be Good.
PM-2.5: 24-hour Fine Particulate concentrations will be mostly Good with only a few chances for low Moderates.
FORECAST DISCUSSION:
High pressure slides in Monday ending scattered lake effect showers across the northern portions of the state. Dry conditions will be short-lived, however, as a low-pressure area brings a cold front through late Tuesday/early Wednesday. Moisture lingers as cold air filters in keeping scattered showers in the forecast Wednesday. High pressure moves back in behind this system with dry conditions expected though the end of the workweek.
As for air quality, weather systems every other day will not allow for any extended period of stagnation, therefore, mostly Good air quality levels are expected through Friday. The only exception may be lighter winds early Friday, especially in the southeast, which may cause hourly Moderate fine particulate concentrations during the morning and early afternoon. Readings should improve to Good as winds pick up in speed during the afternoon.
EXTENDED FORECAST:
Extended models show a weak system possibly bringing scattered precipitation Saturday, and a second system with better chances for precipitation coming in late Sunday/Monday. Warmer southerly winds may allow for some low Moderate fine particulate readings this weekend through early next week; however, ozone will be Good.
