.DISCUSSION...
Issued at 142 PM EDT Sat Jun 6 2026

Currently another day of calm weather as we remain under the ridge
sitting over the southeastern United States. But winds have turned
more southerly so our dew points and temperatures are ticking up as
a low/trough tries to move north through the plains states into the
midwest. This system will try and make inroads into the ridge that`s
been over the southeastern US, but looks to lose out and  remain
over the Ohio Valley as we head into next week.

Rain chances do increase tomorrow and pretty much through the rest
of the upcoming week as we get into a more hot and humid pattern.
Generally near or above normal temperatures and dew points in the
upper 60`s to low 70`s will be in play for most of the upcoming
week. There will be a few disturbances expected to move through and
provide times of enhanced  coverage, but even without that the very
warm temperatures means we should expect to see the return of
diurnally driven showers and thunderstorms. Much of next week looks
to see an extremely saturated atmosphere with PWAT values hovering
around the 2 inch mark until late in the week. This means that any
showers and storms that develop will be very effective rain-makers.
The profile soundings show tall, skinny CAPE which hints at
efficient rain production, and would also tend to limit the severe
threat a bit (although not completely eliminate it). There is no
major strong synoptic forcing for longer range models to try and
depict, so it`s hard to pinpoint where the highest risk for flooding
may be next week. As the week continues on and we see some places
get multiple rounds of moderate to heavy storms expect to see the
threat for flash flooding increase, but confidence on timing and
location at this time is very low until we see where early week
storms and rainfall end up occurring.

(00Z TAFS)
Issued at 725 PM EDT Sat Jun 6 2026

VFR conditions to continue for most locations for most, if not
all, of the period. Low probability for fog tonight at KTRI, but
not enough confidence to include in the TAF. Otherwise, rain
showers, with a few embedded TS, will be moving north out of AL/GA
tomorrow afternoon, with possible impacts to KCHA post 18z.
