FORECAST SUMMARY:
Monday, August 3rd, 2020 through Friday, August 7th, 2020
OZONE: 8-hour average Ozone concentrations will be mostly Good with Moderates possible Friday.
PM-2.5: 24-hour average Fine Particulate concentrations will be mostly Good with a few low Moderates, mainly in the southeast.
FORECAST DISCUSSION:
Clouds and chances for precipitation are in the forecast Monday and Tuesday thanks to upper level disturbances moving through the region. High pressure at mid-week will dry conditions and provide cooler than normal temperatures for a couple days. Warmer conditions look to move in for the end of the week and into the weekend.
As for air quality, weather conditions will not be conducive for ozone development through Wednesday; therefore, mostly Good ozone is expected. High pressure overhead will produce plenty of sunshine by Thursday and temperatures warm closer to 80 on Friday. Lighter winds turning southerly could allow for Moderate ozone in some locations Thursday and/or Friday.
By Saturday, winds pick up from a southerly direction and both surface and upper level temperatures increase. Weather conditions turn more conducive for ozone development by the weekend so we will update the forecast Friday to detail any potential increase for the weekend into early next week.
Fine particulate through mid-week will continue mostly Good with only a few locations in the southeast possibly averaging low-Moderate for the day. Like ozone, by the end of the week a few more Moderate levels are possible.
EXTENDED FORECAST:
Extended forecast maps show warmer temperatures into early next week, but what is uncertain is a possibility of storm activity. More details on the extended forecast will be posted Friday.
