Gradual warming trend takes place early this week

The airmass over the Tennessee Valley Sunday remains comfortable for early August, though it will be hot again. Afternoon temperatures will range between 90 and 95 degrees. The wind won’t be as strong today, but the northerly component will keep the humidity level in check once again. Temperatures jump into the upper 90s to near 100 degrees Monday through Wednesday afternoon before more seasonable temperatures (near 90 degrees) arrive late in the week.

The Valley should remain free of rain through at least Monday afternoon, and many spots won’t see measurable rain again until at least Thursday. We’ve pushed back the odds of heavier, more widespread rain until Thursday through Saturday morning, but expect further adjustments as the week progresses.
