.DISCUSSION...
Issued at 135 AM EDT Fri Oct 17 2025

Broad upper ridging extends northward from the northern gulf coast
states to the Great Lakes region. The surface reflection is a 1022
mb high pressure center located southeast of the Great Lakes. The
upper ridge and surface high will slowly move east-southeastward and
will be located along the eastern seaboard by Saturday morning. This
pattern will keep a predominant east-northeast wind flow, partly
cloudy skies and dry conditions over the Florida peninsula through
Saturday. By Sunday morning, the upper ridge and surface high has
shifted farther southeastward off the Carolina coastline between the
Bahamas and Bermuda. Farther to the north, upper level troughing and
an area of low pressure moves through the Great Lakes region with a
cold front extending southward through the Ohio River Valley and
into the north central gulf. The trailing edge of this weak cold
front will approach the area from the northwest on Sunday. This will
bring a shift in the winds to the southeast and southwest and also
bring a slight uptick in moisture over the region. Rain chances
remain on the low side, but can`t rule out a stray shower as the
front moves through on Sunday into early Monday. The front pushes
south and east of Florida and dissipates on Monday as high pressure
builds back in over the southeast U.S. with pleasant weather
expected for most of next week. Near seasonal temperatures expected
through the period with daytime highs in the mid to upper 80s and
overnight lows in the upper 50s to low 70s.

.AVIATION...
(06Z TAFS)
Issued at 135 AM EDT Fri Oct 17 2025

VFR, rain-free conditions and east-northeast winds less than 12
knots expected through the period.

&&

.MARINE...
Issued at 135 AM EDT Fri Oct 17 2025

High pressure north of the area will produce rain-free conditions
and prevailing east-northeast winds around 10-15 knots through the
day, with some brief periods of increasing winds to Cautionary level
overnight tonight and again on Saturday night. The only chance of
any showers will come on Sunday as a weak front moves across the
eastern gulf waters. High pressure then builds back into the area
for the first half of next week with pleasant weather expected.

&&

.FIRE WEATHER...
Issued at 135 AM EDT Fri Oct 17 2025

Pleasant weather expected for most of the period with only a slight
chance of a shower on Sunday. No fire weather hazards are expected
as sufficient moisture will keep minimum afternoon relative humidity
values above critical levels.
