Synopsis -
as high pressure over the area weakens tonight and into the early week dominant period, conditions will become less hazardous. However, hazardous winds will still continue through Monday morning before subsiding. Thus, hazardous marine conditions will continue as winds and seas remain elevated.
gulf stream hazards: easterly winds 15-20 knots with gusts to 25 knots and occasional 7 foot seas.

New UPDATE, AVIATION, MARINE

UPDATE
Issued at 1039 PM EDT Sun Apr 28 2024

Mostly quiet again across east central Florida this evening. The pressure gradient loosens a bit as high pressure off the Carolinas slowly shifts farther offshore, allowing easterly winds to settle to 5-10 mph tonight. A few faint echoes remain on radar from the couple heartier convergence lines over the Atlantic waters, but essentially dry conditions at the moment. Hi-res guidance in pretty good agreement shower activity will pick across the Atlantic waters late tonight, which could push onshore towards the morning. 20 pct PoPs creep back to the coastal corridor by around 8 AM. Mostly clear skies and light winds mean the boundary layer could decouple, so while overnight lows are generally in the 60s, a few locations rural and northern locations could dip below 60.
On the other hand, if onshore winds managed to maintain, locations along the coastal corridor might settle around 70.

AVIATION
(00Z TAFs)
Issued at 1039 PM EDT Sun Apr 28 2024

VFR conditions prevail through the TAF period. Easterly winds 10-15 kts settle to 5-10 kts while veering slightly to the southeast, then pick back up to 10-15 kts with gusts to around 20 kts after 15Z Monday, shifting back towards easterly after 21Z.

MARINE
Issued at 1039 PM EDT Sun Apr 28 2024

Tonight...Boating conditions improve, but remain unfavorable to poor. High pressure off the Carolinas will slowly shift farther offshore, loosening the pressure gradient across the local Atlantic waters. Easterly winds veer slightly to southeasterly at 10-15 kts north of Sebastian inlet, and 15-20 kts to the south.
Seas up to 6 ft in the Gulf Stream subside through the night, but small craft should continue to exercise caution.

PREVIOUS DISCUSSION
Issued at 345 PM EDT Sun Apr 28 2024

Key Messages: -High risk of rip currents at Atlantic beaches.
-Poor to hazardous boating conditions continue tonight.
-Slight rain and storm chances early this week.

Through Tonight...We have developed a healthy cu field this afternoon, save for the coast where a sea breeze is embedded in the easterly flow. A handful of stray showers / sprinkles have dotted the shoreline this afternoon, but the subsidence inversion resides just above H85 which is limiting appreciable shower coverage for now. Into tonight, CAMs bring another batch of deeper moisture from NE of the Bahamas toward our coastline by dawn.
Much of the night should be dry with only sprinkles noted east of I-95, especially after midnight. Lows 65-72F near the coast, with low/mid 60s in most inland locales.

Monday...A mid-level ridge axis scoots east of our longitude as surface high pressure remains entrenched between Myrtle Beach and Bermuda. E/SE winds continue but subside slightly as the pressure gradient tries to relax a little bit. 28/12Z HRRR members indicate that the moisture profile deepens tomorrow (lowest 250 mb), likely prompting somewhat better coverage of onshore-moving showers. For now, we have a slight chance (20%) only along the coast. Cloud- bearing winds veer more to the SE which could keep the activity from getting quite as far inland as what we saw yesterday. Partly sunny skies prevail again, with highs in the low 80s along the coast to the mid 80s from Clermont to Orlando to Okeechobee.

Monday Night-Tuesday...Isolated rain chances are forecast to continue Monday night, mainly along and east of I-95, as marine showers work onshore. Locations along the Treasure Coast could pick up to 0.20" of rain by daybreak Tuesday. Temperatures overnight into Tuesday remain mild in the 60s, close to 70 degrees at the coast. An upper ridge axis slides east on Tuesday as a weak mid level wave moves across Florida. The resulting afternoon sea breeze may become a bit more active, supporting showers and an isolated storm as it pushes inland. Right now, the highest storm chances look focused south of Melbourne, from I-95 along the Treasure Coast to Okeechobee County.

Wednesday-Saturday...As mentioned in this morning's forecast, the pattern will remain largely unchanged through late week as high pressure maintains its influence over the western Atlantic, southeast U.S., and Caribbean. Drier air gradually intrudes from the north Thursday into early next weekend, reducing cloud cover and leaving room for plenty of sunshine. Therefore, a gradual increase in daytime highs remains forecast from Wednesday onward, with inland locations reaching the upper 80s to low 90s and coastal sites staying slightly cooler due to the east coast sea breeze. Overnight lows remain seasonable in the mid 60s.

MARINE
Issued at 345 PM EDT Sun Apr 28 2024

Tonight-Monday...Poor boating conditions stick around over the local Atlantic. Seas will be slow to subside tonight as east winds persist from 12-17 KT. Moderate ESE breezes continue on Monday from 10-15 KT. So, expect seas 4-6 FT tonight to gradually taper toward 3-5 FT tomorrow. Inshore/Intracoastal boaters will experience a moderate chop. 20-30% chance of showers through the period.

Tuesday-Thursday...Continued improvement to boating conditions is forecast through mid week and favorable conditions will likely last into early next weekend. SE winds 10-15 kt Tuesday slacken to around 10-13 kt Wednesday and Thursday. Seas 3-4 ft nearshore Tuesday, up to 5 ft offshore. By mid to late week, seas fall to 2-4 ft. Isolated showers and even a lightning storm or two is possible over the waters, especially on Tuesday.

FIRE WEATHER
Issued at 345 PM EDT Sun Apr 28 2024

Monday...Steady east-southeast winds from 10-15 mph with gusts to around 20 mph are expected. This will combine with RH minima from 35-40% generally west of Orlando to Okeechobee to, yet again, prompt fire-sensitive weather conditions in the afternoon.

Tuesday-Saturday...Southeast winds persist 10-15 mph with gusts up to 20 mph each afternoon. Minimum relative humidity values recover a bit Tuesday before falling again into the 35-40 percent range mid to late week, leading to fire-sensitive conditions each afternoon.
