Current Conditions and Active Alert

A Heat Advisory is currently in effect for Celina, issued by the National Weather Service in Fort Worth. This moderate-severity alert remains active until 8:00 PM CDT this evening. As of this afternoon, the air temperature stands at 97F, but the combination of heat and humidity means it feels like 104F.

The relative humidity is 42%, with a dew point of 70F, contributing to the muggy conditions. Winds are blowing from the south at 11 mph, with gusts recorded at 9 mph, and the sky remains clear. The current heat index values are reaching 104F, posing a risk of heat-related illness for those spending time outdoors.

Today’s Forecast and Tonight’s Outlook

For the remainder of today, expect sunny skies with a high near 99F. The heat index values could reach as high as 106F, making the perceived temperature significantly higher than the actual air temperature. South winds will continue around 10 mph.

The chance of precipitation is minimal, at just 2%. As night falls, conditions will remain mostly clear. Temperatures will drop to a low near 79F, though they may rise slightly to around 81F overnight.

The heat index values will remain elevated, reaching as high as 103F. Winds will shift to the south-southeast, blowing between 5 and 10 mph. Residents should continue to monitor their hydration levels and limit strenuous activities during these warm evening hours.

Tomorrow’s Outlook and Safety Reminders

Tomorrow will bring a high near 98F with sunny conditions initially. However, the weather pattern will shift, bringing a chance of showers and thunderstorms after 1:00 PM. The overall chance of precipitation is 50%, with new rainfall amounts expected to be less than a tenth of an inch.

Heat index values will still reach as high as 104F, so the dangerous heat conditions will persist into the afternoon. Winds will be lighter, around 5 mph from the south. Tonight, the chance of showers and thunderstorms continues, with mostly cloudy skies and a low near 77F.

Given the persistent heat and potential for thunderstorms, it is crucial to stay informed. Drink plenty of water, avoid prolonged sun exposure, and check on vulnerable neighbors. If you must be outside, seek shade and take frequent breaks to cool down.
