Very hot weather builds in Allen
Allen is starting Wednesday overnight under clear sky, but the main weather story is the heat ahead. The air temperature is 77F, and it feels like 78F. Relative humidity is 74%, with a dew point of 68F.
Wind is light at 5 mph, with gusts to 12 mph. The quiet start will not keep temperatures from climbing sharply today, when sunshine is expected and the high is near 102F. The chance of precipitation is 4%, so meaningful rain relief is not expected from the forecast.
Today, tonight and tomorrow
