Oklahoma City is staring down a steamy Father’s Day, with afternoon highs expected to climb into the mid‑90s and humidity pushing the feel-like temperatures well over 100 degrees. A heat advisory will keep the midday into evening hours downright uncomfortable, and then scattered evening storms could build into a larger overnight complex that moves through into Monday morning. Forecasters warn the overnight system could produce pockets of large hail and damaging winds, with the worst hazards favored north of the metro.
Heat peaks this afternoon
Meteorologist Mikayla Smith expects temperatures to top out around 95°F in Oklahoma City, with readings in the upper 90s and even near triple digits across western Oklahoma. Smith notes that Sunday marks the summer solstice, the first official day of summer, and that a heat advisory is in effect through the afternoon and evening. As reported by KOCO, heat index values could reach the 105–110°F range.
Severe storm outlook tonight
The Storm Prediction Center Day 1 outlook places parts of the central and southern Plains under a Slight risk for severe thunderstorms, warning that organized storms could bring very large hail, damaging winds and a few tornadoes. SPC forecasters highlight the potential for supercells to develop from the central High Plains into parts of Kansas and nearby western Oklahoma. That threat is locally higher north of I‑40, although exact storm tracks will determine which neighborhoods see the roughest weather.
Timing and where to watch
Local forecasts call for isolated showers and storms to fire up around 7 p.m., with a larger storm complex likely to organize closer to midnight and push toward the Oklahoma City area in the pre‑dawn hours, roughly 3:30 to 4:00 a.m. Monday. Trailing showers are expected to linger into Monday morning. Forecasters are also flagging a localized hail threat north of the metro near the Oklahoma‑Kansas line and have assigned a modest tornado index in parts of northern Oklahoma. Those timing and hazard details were outlined by KOCO meteorologist Mikayla Smith in her Father’s Day forecast.
How to stay safe
The National Weather Service in Norman recommends standard heat precautions during the peak afternoon hours: drink plenty of water, take breaks and avoid strenuous outdoor work. They also advise having a plan to move activities indoors if storms approach. NWS graphics and products indicate multiple waves of storms from Sunday evening into early Monday and emphasize that any sustained cluster could pack damaging winds as it grows. Check local watches and warnings before heading out, and consider moving outdoor Father’s Day plans earlier in the day or indoors if you are concerned about the weather.
Plan for the heat this afternoon, then keep an eye on the sky after sunset. Forecast details may shift as storms develop and organize, so stay tuned to local updates and alert services for any watches or warnings that may be issued overnight.
