Surface high pressure slides southeastward off the Atlantic Seaboard and settles across the southwest Atlantic. A much drier airmass builds locally with modeled PWATs around 0.7-0.8”, limiting any precip chances. Onshore flow continues remaining out of the east and increasing to 10-15 mph as the sea breeze develops and progresses inland. Afternoon temps reach the M80s across the interior with L80s forecast along the coast and in vicinity of I-95.

PREVIOUS DISCUSSION
Issued at 325 PM EDT Tue Apr 29 2025

Current-Tonight...Isolated showers have moved westward with dry conditions building locally. Partly cloudy skies are forecast to gradually clear as a diffuse east coast sea breeze moves inland through the remainder of the afternoon. Mostly clear conditions are then forecast into the overnight before marine stratocu gradually drifts onshore ahead of sunrise. Low temperatures will mostly range the 60s, remaining warmest along the coast. Although, a few normally cooler rural locations could see lows fall into the upper 50s.

Wednesday-Thursday...Surface high pressure slides southeastward off the Atlantic Seaboard and settles across the southwest Atlantic. A much drier airmass builds locally with modeled PWATs around 0.7-0.8”, limiting any precip chances through mid week.
Onshore flow continues through the period, remaining out of the east to east-southeast and increasing to 10-15 mph as the sea breeze develops and progresses inland each day. Afternoon temperatures reach the mid 80s across the interior with low 80s forecast along the coast and in vicinity of I-95. Low temperatures mostly range the low to mid 60s, although onshore follow will keep coastal locations warmer in the upper 60s.

Friday-Monday (modified previous)...A mid-level ridge begins to erode into Friday as a trough sweeps eastward from the Great Lakes towards New England and the Mid-Atlantic through the weekend. Beyond this, there remains some model discrepancies in the mid-level pattern. However, models are in fairly decent agreement that a weakening cold front will approach the Florida peninsula over the weekend, stalling across south Florida late this weekend into Monday. As a result of this, moisture is forecast to increase across east central Florida. The development of the east coast sea breeze and its push inland will take advantage of the greater moisture, with rain chances increasing to 20 percent on Friday afternoon and 30 to 50 percent each afternoon Saturday through Monday. Isolated storms also cannot be ruled out, particularly Saturday through Monday. Activity is anticipated to diminish into the evening and overnight hours each day, with lingering showers and storms possible out across the local Atlantic waters.

Outside of the shower and storm activity, temperatures are forecast to remain near to slightly above normal each afternoon through Sunday, with highs in the low to upper 80s and lows in the 60s.
Slightly cooler on Monday with highs in the upper 70s to low 80s.
South to southwest winds Friday veer through the weekend, becoming northeast Sunday and Monday. The east coast sea breeze will cause winds to become more easterly each afternoon.

MARINE
Issued at 325 PM EDT Tue Apr 29 2025

Boating conditions improving, but remain unfavorable offshore the Treasure Coast for east winds 15-20 kts. Across the rest of the waters, winds 10-15 kts further diminishing towards morning.
Favorable boating conditions anticipated to set in across the waters by Wednesday, with mostly dry weather prevailing through Thursday. By Friday, rain chances begin to increase once again across the local Atlantic waters as moisture returns via south- southeast flow and an approaching weakening frontal boundary. The best rain chances across the local waters are focused on this weekend as the front moves closer to the area, with PoPs rising into the 30 to 50 percent range. Seas are anticipated to remain between 2 to 4 feet, with veering winds remaining below 15 knots.

AVIATION
(00Z TAFs)
Issued at 720 PM EDT Tue Apr 29 2025

Mainly VFR conditions continuing. ERLY winds diminishing thru the evening and overnight to around 5 kts across the interior, but remaining elevated 10-13 kts along the Space/Treasure coasts during the evening, slowly decreasing to 5-10 kts overnight.
Persistent pattern continues on Wed as ERLY winds gradually increase to 10-15 kts with some higher gusts. Conditions mainly dry.

FIRE WEATHER
Issued at 325 PM EDT Tue Apr 29 2025

Moisture is forecast to diminish starting Wednesday as an area of high pressure drifts southward towards the Florida peninsula, with minimum RH values falling near critical thresholds Wednesday through Friday across the interior. Rain chances remain below 15 percent through Friday, though some isolated showers Friday afternoon along the Treasure Coast cannot be ruled out. Onshore winds persist through Thursday, becoming southerly on Friday as the surface high sits directly east of the peninsula. Wind speeds reach up to 15 mph each afternoon out of the east across the area as winds are enhanced by the local sea breeze. Based on these variables along with continued drying of fuels due to a lack of appreciable rainfall, sensitive fire weather conditions are anticipated across east central Florida over the next several days.

Light winds over the weekend veer as another weakening front begins its approach, with moisture slowly increasing. Winds become easterly each afternoon as the sea breeze develops and moves inland. Rain chances increase into the weekend through early next week, with PoPs of 30 to 50 percent currently forecast across east central Florida. There is also a low chance (20 percent) for storm development, though confidence in this remains low at this time. If storms were to develop, any lightning strikes may be capable of sparking new wildfires.
