The Next 24 Hours – A Chilly, Dry Wednesday
A strong area of high pressure in southern Canada is pushing cold, dry modified arctic air south into the Tennessee Valley now, and that means we have a chilly Wednesday in store! Temperatures start out in the middle and upper 20s with some high, thin cirrus clouds drifting in overhead in the morning hours, and it only warms into the middle and upper 40s by the afternoon with filtered sunshine. Clouds may thicken enough at times to make the sky completely gray, but we do not expect any rain on Wednesday.
That north-northwest breeze stays up around 6 to 12 MPH during the afternoon; occasionally it will feel like it is in the 30s when the clouds temporarily hide the sun for a few minutes!
Thursday is a different story, though! Rain chances rise rapidly in the afternoon and evening on Thursday. Check out WHNT.com/Weather for a look at how rain comes in, goes away, and comes back between Thursday, Friday and Saturday.
