.NEAR TERM...
-- Changed Discussion --
(Through Wednesday)
Issued at 314 PM EDT Tue Jun 18 2024

The upper level high will build over the U.S. Mid Atlantic region,
while surface high pressure holds just to the northeast. This will
allow dry air to be ushered into the region, which combined with low
pressure over the southwest, will lead to a tightening pressure
gradient. This will lead to unseasonably strong easterly winds. The
weather pattern set up should suppress shower and thunderstorm
through the rest of today and into tomorrow, though there could be a
few isolated showers or thunderstorms.

.SHORT TERM...
-- Changed Discussion --
(Wednesday night through Thursday night)
Issued at 314 PM EDT Tue Jun 18 2024

High pressure will hold along with strong easterly flow during
this time frame. A easterly wave from the Atlantic will begin to
creep towards the region, ushering in some moisture. This will
increase precip chances, particularly for the FL counties;
however, confidence is still fairly low with 15-30% north of I-10
into southern GA and 30-45% south of I-10. Highs for Thu will be
in the low 90s and then fall into the upper 60s to low 70s Thu
night.

.LONG TERM...
-- Changed Discussion --
(Friday through Monday)
Issued at 314 PM EDT Tue Jun 18 2024

High pressure will sag a bit to the south during this period and
weaken, allowing for a more typical summer like pattern. The
easterly wave in the Atlantic, currently several hundred miles
east of the Bahamas will, will drift towards the southeast US
coast. This will bring increased showers and thunderstorms to the
region for the weekend. Broad high pressure should settle just off
the Atlantic extending back into the FL peninsula. This will lead
to southeasterly flow and bring us start steering us back to our
typical summertime days with increasing chances showers and
thunderstorms.

.AVIATION...
-- Changed Discussion --
(18Z TAFS)
Issued at 107 PM EDT Tue Jun 18 2024

VFR conditions will prevail with the only aviation hazards being
gusty easterly flow in the afternoons. Sustained winds will be
around 10 to 15 knots through the TAF period but expect gusts from
20 to 25 knots in the daylight hours of the TAF period.

.MARINE...
-- Changed Discussion --
Issued at 314 PM EDT Tue Jun 18 2024

The main update to the forecast package is the introduction of a
Gale Warning this evening through mid Wednesday morning as
frequent gale force gusts are expected for the majority of the
Gulf waters. Strong easterly breezes and rough seas will then continue
over the northeast Gulf through Friday morning, thanks to a tight
pressure gradient between strong high pressure off the New
England coast and a developing tropical cyclone over the Southwest
Gulf. Winds will start to decrease on Friday, as the high
pressure center to our northeast moves closer to Bermuda and
extends a ridge axis across the Southeast States.

.FIRE WEATHER...
-- Changed Discussion --
Issued at 314 PM EDT Tue Jun 18 2024

Our weather will generally be dominated by high pressure over the
next few days; however, the pressure gradient over us will tighten
due to low pressure over the Bay of Campeche developing.
This will lead to unseasonably strong breezes through the week, deep
mixing, and high dispersions through at least Thursday. Mainly dry
weather should supress shower and thunderstorms each afternoon,
though a few rogue showers or storms could pop up. The pattern may
change to a wetter one late in the week, but confidence is low on
timing for this.

.HYDROLOGY...
-- Changed Discussion --
Issued at 314 PM EDT Tue Jun 18 2024

Significant or widespread flooding is not expected through this
weekend. Little, if any, rain is expected through Thursday. Rain
chances will increase some starting Friday, but rainfall should
not be hydrologically significant.

By Monday and Tuesday of next week, ensemble mean solutions show
1000-700 mb flow becoming southerly, pumping up a more richly
moist maritime tropical air mass. With more moisture to work
with, rainfall loading beneath storms will increase, as steering
flow weakens and storm motions slow down. Therefore, there is
increasing potential for isolated flash flooding starting early
next week.
