Local Impact of Tropical Storm Edouard
Tropical Storm Edouard is tracking toward the Texas-Louisiana border, bringing a shift in local weather patterns for McKinney. While the heaviest rainfall is expected over Southeast Texas, residents here can anticipate a modest increase in precipitation chances and a break in the recent heat.
The storm is forecast to turn west-northwest and weaken as it approaches Central Texas, meaning the direct impact on McKinney will be limited to slight chances of showers and thunderstorms rather than severe weather.
Currently, the air temperature is 90F, feeling like 95F with relative humidity at 52%. The sky is clear, and winds are light at 6 mph. This dry, hot start to the day is typical before the system begins to influence the region. As the storm moves closer, the atmosphere will become more unstable, leading to the slight chance of precipitation noted in the forecast.
