.DISCUSSION...
Issued at 156 AM EDT Fri Jun 6 2025

Saturated soil from recent rainfall along weak boundary layer
winds will promote fog developing through the remainder of the
overnight and early morning hours. Meanwhile, a weak frontal
boundary will linger across the region through today, bringing
isolated showers and thunderstorms, particularly east of I-69
and south of US-24. High temperatures will remain near normal,
in the mid to upper 70s, with overnight lows in the mid 50s to
around 60. By Saturday, high pressure will build in, leading to
drier conditions and more sunshine, with temps rising into the
upper 70s to low 80s.

On Sunday, we may see a resurgence of scattered to numerous
showers and storms as a surface low traverses through the
Midwest. In fact, it`s possible that blended guidance is lagging
behind in PoPs, as recent deterministic runs look rather wet
Saturday night through Sunday. However, it`s worth noting
these operational runs are on the wetter side of their ensemble
envelope. Temperatures will run near or just below average for
this time of year through Tuesday.

By midweek, a more pronounced warming trend is expected with
the return to low/mid 80s. Drier conditions, at least
temporarily, will prevail before signals point back towards
higher rain chances in time for next weekend.

.AVIATION /06Z TAFS THROUGH 06Z SATURDAY/...
Issued at 130 AM EDT Fri Jun 6 2025

Surface boundary will remain draped south of the terminals for
most of this forecast valid period which will keep light
northeast flow in place along with relatively poor mixing
profiles. This should allow low clouds to linger through much of
the day, with some improvements this afternoon from the morning
IFR/LIFR conditions. KSBN should see the earlier improvement
where drier low level air will become established later this
afternoon. Abundant near sfc moisture north of the boundary will
allow for some areas of fog and perhaps some patchy drizzle at
KFWA through the early morning hours. KSBN remains VFR as of
05Z, but near term progs still support idea of easterly low
level flow helping to promote some weak low level moisture
advection from Lake Erie vicinity back across the southern Great
Lakes. Thus, have made no major change in trend back to MVFR
cigs at KSBN after 07Z.
