Today - Tonight
A broad area of high pressure across the western Atlantic will remain in place, with the associated ridge axis settling across central Florida. Dry conditions are forecast to persist, with mostly sunny skies remaining in place. With the ridge axis draped across the peninsula, winds are forecast to remain light and variable this morning, becoming easterly this afternoon as the east coast sea breeze develops and moves inland as a result of the temperature gradient between the peninsula and the local Atlantic waters. Afternoon highs will be slightly warmer than the last couple of days, roughly in the low 80s along the immediate coast and reaching the mid to upper 80s across the interior. Winds will begin to diminish late, becoming generally southeasterly and even variable at times overnight. Dry conditions will continue into the overnight hours. Lows in the upper 50s to low 60s.
Fri-Sun...Mid-upper level ridging will hold tight across the southeast U.S. and FL peninsula thru the weekend. Mid-level impulses will occasionally slide down the peninsula during this time, though we retain mostly dry conditions with a stable onshore surface flow and less than modest moisture. However, will not rule out a few showers across the local coastal waters. Surface high pressure will dominate across much of the eastern CONUS. This will allow for a persistent onshore flow and the pgradient will be tight enough for breezy conditions each afternoon, especially along the coast. Afternoon highs in the U70s to L80s near the coast and L-M80s into the interior, possibly some U80s Fri afternoon toward the Kissimmee River. Overnight lows mild and well into the 60s each early morning.
Mon-Thu...The upper ridging begins to break down and shift off of the Atlantic Seaboard into the western Atlc. Initial surface high pressure off of the Carolinas will also weaken thru mid-week, while gradually shifting southward. The onshore surface flow stays mostly intact, though the pgradient will slowly weaken during this time. Continue to keep conditions over land dry. A warming trend will begin, with L80s at the immediate coast, perhaps some M80s here by Thu, and M-U80s into the interior - perhaps some readings near 90F well into the interior by Wed/Thu. Overnight lows remain consistent and in the 60s areawide.

Today - Tonight
Generally favorable boating conditions will persist across the local Atlantic waters. An area of high pressure will continue to keep conditions dry, with light and variable winds this morning becoming east-southeast across the waters at 5 to 10 knots. Seas will remain between 2 to 4 feet today into tonight.
Fri-Mon...Less than favorable boating conditions going forward. ERLY winds on Fri gradually increase to 10-16 kts during the day, 15-20 kts Fri night with Cautionary Statements necessary, and the pressure gradient continues to tighten Sat-Sat night 16-22 kts (marginal Small Craft Advisory criteria), then slowly backing off Sunday 14-19 kts and Mon, again, 10-16 kts. Initial seas 2 ft near shore and 3 ft Gulf Stream will gradually build in response to the increasing winds, 4-6 ft by daybreak Sat morning, 5-6 ft during the day on Sat, 5-7 ft Sat overnight - gradually/slowly subsiding Sunday afternoon-Mon. While conditions will remain mostly dry, cannot rule out some isolated shower activity thru this period.
Fire Weather
Issued at 238am EDT Thu April 25 2024
Today...Sensitive fire weather conditions will still exist across east central Florida as minimum RH values drop into the 30 to 45 percent range. Winds will be light and variable this morning, becoming easterly around 10 mph as the east coast sea breeze develops and moves inland.
Fri...Min RHs recover a bit into the U30s to M40s inland and 50- 55pct near the coast. Easterly winds increase to 10-15 mph, with perhaps a bit gusty along the coast.
Sat-Mon...Onshore winds increase a bit more into the extended 15 mph/15-20 mph. Min RHs stay above critical levels on Sat, but as temperatures climb Sun-Mon, we will see values fall back to 35-40pct over the interior on Sun/Mon.
