Oklahoma City faces a warm, sunny Friday, Oct. 9, with temperatures rising from the low 60s in the morning to near 90 in the afternoon. An ozone Air Quality Alert is in effect Friday, adding a health concern to the heat.
What the ozone alert means
An alert is a forecast that ozone pollution could reach levels unhealthy for sensitive groups; it does not confirm that those levels have been measured. That distinction is outlined by the Oklahoma Department of Environmental Quality. DEQ identifies children, older adults and people with underlying lung diseases such as asthma as especially vulnerable to unhealthy ozone effects.
During the alert, people with heart or respiratory conditions are advised to reduce strenuous outdoor activity. Residents can also limit unnecessary driving, refueling and outdoor burning. Tuesday’s high is forecast near 85 degrees.
How warm is that for October?
The National Weather Service Norman’s Oct. 9 climate report puts Oklahoma City’s normal high for the date at 76 degrees and its record at 96, set in 1965. A forecast high near 90 would be well above normal but below the record. The report also lists an observed high of 87 degrees on Oct. 8, 11 degrees above that date’s 76-degree normal. These date-specific readings offer local context, but they do not establish a broader temperature trend.
The same report shows 1.30 inches of precipitation for October through Oct. 8, compared with 0.87 inches normal to date. That recent total is a baseline, not a prediction of how much rain the approaching system will bring.
Rain chances rise midweek
The forecast gives a 20% chance of rain Tuesday, with chances increasing Tuesday night into midweek. Forecasters are watching for potentially strong storms as warm, moist air meets an approaching system, but the forecast does not establish whether severe weather will occur or how much rain will fall. Thursday’s high is expected to ease to around 83 degrees.
Until conditions change, drink water, seek shade and shorten outdoor exertion during the hottest part of the day. People who are sensitive to ozone should also follow the alert’s activity guidance.
