Area Forecast Discussion

...New LONG TERM...

.SHORT TERM...
(Rest of today through Thursday)
Issued at 1232 PM EDT Wed Sep 27 2023

South FL will remain unsettled through Thursday as a frontal
boundary remains across northern FL and low level SE flow continues
to pump in rich moisture. Morning 12Z sounding showed a PWAT value
of 2.42 inches with the column nearly saturated through 500 mb. HREF
shows similar PWAT values remaining across the area through
Thursday. PoPs this afternoon/evening and again on Thursday will
remain above climatological norms with numerous showers and storms
across the area. With the high PWAT values, storms will be capable
of high rainfall rates, thus localized urban flooding will remain a
threat. WPC has much of the area in a marginal risk for excessive
rain both today and Thursday. Cloud cover this morning helped to
keep the atmosphere a bit more stable, but breaks in the clouds this
afternoon should help de-stabilize things quickly. While severe wx
is not the primary concern, a few stronger storms can't be ruled out
with strong wind gusts the primary threat.

High temps today and Thursday will generally be in the upper 80s,
and low temps tonight will range from the lower 70s around the lake
to mid and upper 70s elsewhere.

&&

.LONG TERM...
(Thursday night through next Tuesday)
Issued at 139 PM EDT Wed Sep 27 2023

The unsettled pattern will continue through the end of the week
and into the first part of the upcoming weekend as we remain on
the warm/moist side of the nearly stationary boundary to our
north, and weak synoptic ascent remains present over the area
downstream from troughing over the GOM. PWATs will remain 2.1-2.3
inches through Saturday with synoptic southeasterly flow generally
resulting in the storm focus shifting north and west diurnally.
Naturally in this regime, heavy rainfall and flooding will remain
a concern, although at this range pinpointing specific
impacts/risks remain difficult as more mesoscale factors such as
cloud cover, convectively-enhanced shortwaves, and mesoscale
boundaries haven't come into focus.

The pattern shifts Sunday into early next week as the flow trends
more NErly and a considerably drier airmass (PWATs < 1.5 inches)
pivots into the area by Monday. Sunday likely remains fairly
unsettled as a potent shortwave pivots into South Florida, and the
moisture boundary approaches the area. Some drying south to north
then looks likely on Monday with rain chances finally decreasing
into the Chance range (40-50%) in the drier airmass on Tuesday.

High temperatures will generally be in the upper 80s to near 90
through most of the extended period with lows mostly in the mid to
upper 70s, although some modest cooling is possible early next
week as the drier air filters in.

.AVIATION...
(18Z TAFS)
Issued at 108 PM EDT Wed Sep 27 2023

SCT to BKN MVFR ceilings this afternoon. Convection late this
afternoon into early evening may result in brief flight
restrictions and erratic winds. Outside of thunderstorms, winds
will be SE around 10 kts this afternoon into early evening become
light and variable tonight.

&&

.MARINE...
Issued at 1232 PM EDT Wed Sep 27 2023

Generally light to moderate easterly to southeasterly winds will
prevail through the end of the week as high pressure is positioned
north of the area. Scattered to numerous showers and thunderstorms
will be possible through the weekend which could result in locally
hazardous marine conditions. Seas 2 ft or less today increasing to 2-
4 ft in the Atlantic by the end of the week as northerly swell
increases due to a system off the SE coast.

&&

.BEACHES...
Issued at 1232 PM EDT Wed Sep 27 2023

A high risk of rip currents will continue for the Palm Beach County
beaches through Thursday evening with a moderate risk for the
Broward County and Miami-Dade County beaches. An elevated risk of
rip currents is likely to persist for the Atlantic beaches through
at least late week as onshore (easterly) flow persists. Minor
coastal flooding is possible during high tide cycles this week along
the Atlantic coast this week due to King Tides. A Coastal Flood
Statement has been issued for the Atlantic coast of South Florida
through at least Thursday evening.
