.DISCUSSION...
Issued at 213 PM EDT Sun Apr 5 2026

Currently, cooler and drier air continues to filter in behind the
departed cold front as surface high pressure builds in from the
west. A rather uneventful weather week looks to be on tap for this
forecast period. High pressure will remain in control through
Monday, then a moisture starved cold front will approach late Monday
and push through our area Monday night into Tuesday before washing
out. No precipitation is expected with this front, but another shot
of cooler air will move in behind it.  We will start the week with
temperatures around or even slightly below seasonal normals and
there may be some late night/early morning patchy frost in a few
areas during the next few nights, especially north, with the coldest
night likely to be Tuesday night.

Relative humidity values will be low each day as well over the next
several days, with minimum values likely dipping at least as low as
the upper 20s and 30s each afternoon across much of the area.

High pressure will continue to keep us dry for the remainder of the
period through Sunday, along with a warming trend beginning
Wednesday and continuing through the upcoming weekend.  Temperatures
will be back to well above normal by the weekend.

Any brief low cigs at TYS/TRI will quickly clear out with VFR
conditions expected all sites for the remainder of the period.
May be some fog around sunrise at TRI but right now the probability
of occurrence looks too low to include.
