Current Conditions

It is currently Sunday morning in McKinney, and the sky is clear. The temperature is sitting at 70F, which matches how it feels right now. Humidity is at 78%, with a light north wind of 3 mph keeping things calm.

Today's Outlook

Expect a sunny day ahead with a high near 96F. Rain chances remain at or below 0% through this evening, so you can count on dry conditions. This high is about the same as yesterday’s, meaning temperatures are holding steady rather than spiking immediately. Winds will pick up slightly to 5 to 10 mph from the north during the day.

Tonight and Tomorrow

Temperatures will drop to a low near 72F tonight under clear skies. It is worth noting that temperatures may rise to around 74F overnight before morning arrives.

Looking ahead, tomorrow will be sunny with a high near 99F, making it about 3F warmer than today. The heat index could reach as high as 99F, so staying hydrated is key. Winds will shift to the southeast at 0 to 5 mph. Overnight tomorrow night, expect clear skies and a low around 76F.
