Your day
A hot, gray morning turned scorching and mostly sunny this afternoon, staying hot into a gray evening; heat indices near 100° make shade and water worth planning around.
Tonight's forecast low of 77° would be warmer than the 73° warmest low on the books for the date, set in 1954. Steady south winds off the Gulf keep the muggy air in place overnight.

‹The scorecard · this week›
Plano's high should reach about 91° this afternoon, nearly 10 degrees above the 81.3° average for the date, with dewpoints near 70° pushing the heat index toward 100°. The 95° record, set in 1954 and tied in 2024, looks safe (records since 1948).
After Thursday's forecast high of 88°, a strong cold front sweeps through Thursday night, and Friday's high should only reach 71°. North winds behind it could gust near 30 mph around 1 AM Friday, with the windiest models near 45 mph.
Next Sunday's high spans 62° to 91° across the models, depending on how soon high pressure slides east and south winds return. We hold it at 76°, leaning cool, since the dry post-front air should linger through the weekend before warming starts.
