Cooler than normal temperatures, ozone alert in forecast for July 4

GREENVILLE — After a pleaseant, but unseasonably cool, morning in Greenville, revelers looking forward to the July 4 holiday can expect a reasonably cool — for July in Texas — Independence Day, marked by an alert for possible high levels of ozone in the atmosphere.

The thermometer at Majors Field, the City of Greenville Municipal Airport, dipped all the way down to 59 degrees Wednesday morning. The National Weather Service forecast is calling for mostly sunny skies and a high near 89 degrees this afternoon.

For July 4, the forecast is calling for another sunny day and a low in the mid-60s overnight — so it should be wonderful weather for tomorrow's Firecracker 5K, Buena Vista/Chapman and Park Street parades and all of the other activities during the morning — and a high of around 93 degrees during the afternoon.

But the forecast is also calling for little to no wind Thursday, which has prompted the issuance of an Ozone Action Day alert:

...OZONE ACTION DAY...

THE TEXAS COMMISSION ON ENVIRONMENTAL QUALITY (TCEQ) HAS ISSUED AN OZONE ACTION DAY FOR THE DALLAS-FORT WORTH AREA FOR THURSDAY,
JULY 4, 2013.

ATMOSPHERIC CONDITIONS ARE EXPECTED TO BE FAVORABLE FOR PRODUCING HIGH LEVELS OF OZONE AIR POLLUTION IN THE DALLAS-FORT WORTH AREA
ON THURSDAY. YOU CAN HELP PREVENT OZONE POLLUTION BY SHARING A RIDE, WALKING, RIDING A BICYCLE, TAKING YOUR LUNCH TO WORK,
AVOIDING DRIVE-THROUGH LANES, CONSERVING ENERGY, AND KEEPING YOUR VEHICLE PROPERLY TUNED.

Temperatures should start falling shortly after the Patriotic Picnic starts at the Greenville SportsPark at 5:30 p.m. Thursday, and it will likely be very comfortable around the time the fireworks start after dark, with a low back down in the 60s expected by Friday morning.
