FORECAST DISCUSSION:
Today, Tuesday, looks to be warm but will have intermittent cloudiness throughout the day. Also, the wind direction looks to remain more southerly with a slight easterly component to it. Expect Moderate Ozone concentrations for the southern portions of the state with the possibility of isolated hourly USG levels. Overall, 8-hour averages for Ozone should remain in the Moderate range, however.
Following some cloudiness on Tuesday, ample sunshine will ramp up Ozone development for southern portions of the state throughout the afternoon on Tuesday. The forecast for Wednesday has remained consistent with sunny skies, surface temperatures in the upper 90s F, warm upper-level temperatures, and both surface and upper-level southwest winds. These conditions warrant an Air Quality Action Day Advisory for the areas listed above for USG level Ozone concentrations. Thursday presents a slight cool down with a cold front making its way through the region early Thursday morning, which should help to clean out the airmass and lower Ozone concentrations. This forecast is made out until tomorrow in case conditions change and the current forecast needs to be reassessed.
PM-2.5 concentrations look to remain in the Good to Low-Moderate range.
EXTENDED FORECAST:
Models are still showing a cool down this weekend, but as stated above, I will be updating the forecast tomorrow, Wednesday.
