FORECAST SUMMARY: Monday, June 24, 2024, through Friday, June 28, 2024
OZONE:
8-hour average Ozone concentrations are expected to range between Good (Green AQI) and Moderate (Yellow AQI).
PM-2.5:
24-hour daily average Fine Particulate concentrations will also range between Good and low Moderate.
FORECAST DISCUSSION:
High pressure will dominate conditions on Monday with plenty of sunshine and seasonable temperatures. By Tuesday, however, a more active weather pattern sets up. The pattern change begins as an area of storms tracks northwest to southeast across the state late Monday night into Tuesday morning. These storms are associated with a frontal boundary that will drop in as well, and this boundary will keep precipitation in the forecast through early Wednesday. A dry out is expected Thursday into Friday as high pressure briefly settles in, but the next system moves in from the west, with precipitation moving back into the state from west to east as Friday progresses.
As for air quality, cooler conditions, along with on-and-off clouds and precipitation, will hamper ozone development, keeping readings in the Good to Moderate range. The active weather pattern should keep the atmosphere well mixed, and at this time, the upper-level wind pattern is not expected to bring any wildfire smoke from active Canadian fires into the region. Levels of PM2.5 during the week will range from Good to low Moderate.
EXTENDED FORECAST:
Precipitation chances continue into Saturday, but high-pressure returns on Sunday, bringing in dry conditions for early next week. During this period, both ozone and PM2.5 should range between Good and Moderate.
