.DISCUSSION...
Issued at 124 PM EDT Sat Sep 5 2026

The holiday weekend started off on the warm, humid and for some
stormy side. However, the pesky upper ridge aiding in this pattern
will retrograde somewhat and allow a brief return to more seasonable
temperatures (around 80 in the afternoon and 50s at night) through
the remainder of the extended weekend. Thereafter, the ridge tries
to edge back NE Tuesday allowing slightly warmer and more humid
conditions to return (still dry). A trough scoots across the
northern US mid week, flattening out the ridge and allowing a weak
boundary to linger in the area with some low end chances for showers
and storms mainly Wed night into Thursday.

Additional waves pass north of the area, helping to limit the ridge
from building back in (dangerous heat and humidity remains south of
the area) with possibly some chances for showers and storms with
each wave into next weekend.
