.DISCUSSION...
Issued at 215 AM EDT Mon Apr 6 2026

In the upper levels, a deep trough is over the Eastern U.S. At the
surface, high pressure is building into the Midwest and Ohio Valley
today. By midweek, a weak ridge builds into the Southeast and high
pressure at the surface will be centered over the Northeast. Ridging
over the Southeast and high pressure at the surface will likely hold
through the weekend. Dry weather will continue all week and through
the weekend. Frost will be possible in Southwest Virginia, Northeast
Tennessee and the higher elevations this morning and tomorrow
morning as ground moisture lingers and temperatures drop in the
morning hours. By Wednesday morning, frost will still be possible
but more patchy as morning RH is lower.

Monday, Tuesday and Wednesday afternoons, will have good mixing
conditions with mostly sunny skies. Therefore, afternoon RH values
will be low in the 25-35% range in many locations. Fire weather
concerns should be minimal with the recent soaking rain and winds
will be light. Highs today and Tuesday will be in the 60s for most
of the Tennessee Valley. A warming trend will start Wednesday with
highs getting into the 70s through Friday and into the 80s for the
weekend.
