.DISCUSSION...
Issued at 255 AM EDT Sat Jun 6 2026

Today-Tonight...Ridging in the mid-levels will remain centered
across the Florida peninsula and the Gulf today, supporting the
surface high centered across the western Atlantic just off the
southeastern US coastline. The surface ridge axis will extend
towards the Florida-Georgia border, resulting in persistent
onshore flow similar to the past few days. Wind speeds of 5 to 10
mph in the morning will be enhanced into this afternoon as the
east coast sea breeze develops and moves inland, with speeds
increasing to 10 to 15 mph. While dry air near the surface and
from 850mb and aloft will act to suppress overall activity, the
persistent onshore flow off of the Atlantic waters means that
isolated, light sprinkles will be possible not only across the
local waters but also along the coast. There is a low chance (20%)
for a shower or two to move inland along the Treasure Coast and
towards Lake Okeechobee, but confidence in this remains low.
Overall, conditions across east central Florida are forecast to
remain mostly dry today through tonight.

The high pressure at the surface and aloft will support a
continued warming trend locally. High temperatures across the
interior are forecast to climb into the upper 80s to low 90s.
Along the coast, the onshore flow will help keep temperatures in
the mid 80s. Tonight, lows will remain seasonable in the low to
mid 70s, with some rural locations falling into the upper 60s.

Sunday-Monday...Late this weekend and into early next week, a
brief omega block is anticipated to develop as two mid-level
troughs set up on either side of an elongated ridge extending
northward towards the Great Lakes. This will keep the mid-level
ridge in place across the Florida peninsula and the Gulf, with the
ridge gradually sliding westward on Monday as the omega block
pattern moves offshore and breaks down. At the surface, high
pressure is forecast to remain situated across the western
Atlantic, with the ridge axis extending just north of east central
Florida. By Monday, the high is forecast to be on a weakening
trend. As it weakens, there is some indication that moisture will
lift northward towards east central Florida, which could lead to
increasing rain chances across the southern portions of the
forecast area. At this time, guidance does remain inconsistent in
just how much moisture will return to the area, with the GFS
favoring the drier solution. The NBM keeps conditions mostly dry
on Sunday outside of some isolated sprinkles, with a 20-25% chance
of showers across the Treasure Coast and Okeechobee County on
Monday. Rain chances may change on Monday if guidance comes into
better agreement.

With high pressure remaining in place, temperatures will continue
to warm, with some spots across the interior reaching above
normal values. Afternoon highs ranging from the upper 80s to low
to mid 90s are forecast, with the warmest temperatures focused
across the interior. Moderate HeatRisk is forecast to overspread a
lot of the populated areas on Monday, with some locations across
southern Lake County and western Orange County even forecast to
reach a Major HeatRisk. Residents and visitors who are planning on
spending extended periods of time outdoors are advised to remain
well hydrated and ensure breaks in the shade or an air-conditioned
building are taken frequently in order to help avoid heat-related
illness. Overnight temperatures will remain near-normal in the
low to mid 70s.

Tuesday-Friday...The omega block breaks down further into
Tuesday, with ridging forecast to slide southward across the east
coast towards the Florida peninsula. Remnant energy aloft from the
western- most trough of the omega block will also travel
southward, prompting a weak cold front to slide south across the
Florida peninsula on Tuesday. The front is anticipated to pass
with little fanfare, though moisture is forecast to increase
significantly compared to this weekend (PWATs recovering into the
1.5 to 2.0" range). Surface high pressure behind the cold front
will slide southward as well, but this is where guidance begins to
split on solutions. Eyes remain on the Gulf as to whether a low
will develop sometime next week, with the position of the low
influencing just how much moisture returns to the Florida
peninsula and therefore, what rain and storm chances will look
like. The Euro and GFS differ significantly on whether the low
will develop or not, which is directly influencing the behavior of
the NBM. For now, the NBM guidance continues to favor increasing
moisture and rain chances, with a 30-50% chance of rain on Tuesday
and Wednesday and a 40-70% from Thursday onward. As guidance
comes into better agreement, rain and storm chances will become
clearer. Temperatures will remain generally in the upper 80s to
low 90s during the afternoon hours, with lows in the low to mid
70s.

.MARINE...
Issued at 255 AM EDT Sat Jun 6 2026

Generally favorable boating conditions are forecast across the
local Atlantic waters this weekend and into next week as high
pressure remains situated across the western Atlantic. The ridge
axis will extend just north of the local waters, keeping flow
generally out of the east through Thursday. Wind speeds generally
remain between 10 to 15 knots, with seas of 2 to 4 feet
anticipated across the local Atlantic waters. While dry conditions
are forecast through this weekend, light, isolated sprinkles
cannot be ruled out across the local waters due to the onshore
flow. Towards the middle of next week, rain and storm chances are
forecast to increase as moisture returns to the area.

.AVIATION...
(12Z TAFs)
Issued at 620 AM EDT Sat Jun 6 2026

Continued mainly VFR conditions through the TAF period, but perhaps
brief MVFR in light shower activity. ERLY winds increase to 10-15
kts, with occasional gusts up to around 20 kts. While mainly dry
conditions are forecast, brief, ISOLD -SHRA (onshore-moving) cannot
be ruled out, esp Treasure Coast terminals. Onshore winds fall to
light again this evening and overnight.
