.DISCUSSION...
Issued at 1147 AM CDT Wed Oct 21 2026
A large upper ridge over the central CONUS slowly progresses into
much of the eastern states through this weekend as a large eastern
states upper trof mostly moves well off into the western Atlantic
though leaves a weaker upper trof lingering just off the East
Coast. The upper ridge dampens out Monday into Tuesday as an
upper trof advances across the western half of the CONUS, possibly
into the Plains. A surface ridge persists across much of the
eastern states, and strengthens over the southeastern states
Friday night into Saturday. Meanwhile on Friday night and Saturday,
a surface low is anticipated to develop near/east of the Bahamas
and track slowly northward, with the pressure gradient tightening
over the forecast area between this system and the strengthening
surface ridge. This results in moderate to strong winds developing over
the marine area Friday night into Saturday night along with the
rip current risk increasing to High and continuing through at
least Sunday night, with a bit cooler air potentially flowing into
the area as well. The pressure gradient looks to relax Monday
into Tuesday which could lead to a decreasing rip current risk.
Our dry weather continues on into next Wednesday as deep layer
moisture remains limited. Highs on Thursday and Friday will be in
the upper 70s to lower 80s, then highs on Saturday through Monday
will be in the mid to upper 70s. Temperatures then trend a bit
warmer going into next Wednesday by which time highs will be in
the upper 70s to lower 80s. Lows each night will mostly range from
the mid/upper 40s well inland to the lower or mid 50s at the
coast. /29

on Monday.
