The forecast remains on track for east central Florida this evening, with minimal adjustments made with the evening update.
High pressure remains in control of the local weather, with the ridge axis positioned just north of Florida. Dry conditions will prevail, with no rain forecast. East-southeast flow diminishes into the overnight hours, with cloud coverage remaining high locally. Seasonable temperatures are anticipated late tonight into early Tuesday morning, with lows in the low to mid 60s.

PREVIOUS DISCUSSION

Now-Tonight...Dry and warm conditions are in place this afternoon with some cirrus and a few cumulus spread across the area.
Temperatures are steadily climbing into the 80s, on track to approach the low 90s across the interior late in the afternoon. In the presence of onshore flow, a diffuse east coast breeze is now moving inland. As a result, winds are gusting a bit in its wake, around 20 mph. Breezy to gusty conditions at times are expected through the early evening as temperatures fall into the low 70s by midnight. High clouds and dry weather stick around through the overnight.

Tuesday-Wednesday...Similar conditions are forecast through the middle of the week as the warm and dry weather pattern holds for east central Florida. Mild morning lows in the 60s will set the stage for temperatures reaching the 80s to low 90s by the afternoon.
Due to lower relative humidity, heat indices will remain a non- issue. However, for those more sensitive to the warmer weather, plan to take breaks in the shade or air conditioning. The onshore flow and gusty conditions along/behind the afternoon sea breeze will provide minimal relief. Wednesday looks to be the warmer of the two days, as mid level warming and slightly clearer sky conditions materialize.

Thursday-The Weekend (previous)...A passing upper level shortwave trough weakens the ridge late week over the western Atlantic.
However, it looks to be almost immediately replaced by additional ridging over the Southeast. This pattern will maintain a ridge axis north of the local area, leading to continued east to southeast flow through the weekend. Overall, the pattern is forecast to remain largely the same, with above average highs in the upper 80s to lower 90s inland, while the daily sea breezes keep coastal areas nearer to normal in the lower to mid-80s. Little relief from fire weather concerns, as the sea breezes become gusty at times, as the pressure gradient tightens slightly. However, have maintained very low (~20% or less) PoPs for the weekend, as increased PWATs closer to 1-1.2" advect into the area. Unfortunately, impactful QPF remains out of the forecast through the period.

East-southeast flow is forecast to continue through the remainder of the week as high pressure influences the local pattern. Gusty winds can be expected behind the afternoon sea breeze, reaching 15-20 kt. Seas generally 3-4 ft, perhaps building up to 5 ft offshore late Thursday and Friday. Very low rain chances return as early as Friday, mainly offshore and south of Sebastian Inlet.

AVIATION
(00Z TAFs)
Issued at 720 PM EDT Mon Apr 21 2025

VFR conditions are anticipated through the period at all east central Florida terminals. Guidance has backed off on the potential for MVFR CIGs late tonight into early Tuesday morning, so have removed TEMPOs from the coastal terminals. Will monitor and amend as needed. East-southeast winds at 10 to 15 knots diminish to around 5 knots overnight at all terminals, picking back up tomorrow morning at 5 to 10 knots. The east coast sea breeze is forecast to develop Tuesday afternoon and move inland, enhancing winds locally and causing the terminals to reach 10 to 15 knots once again. Gusts up to 20 knots cannot be ruled out. Dry through the period, with no rain forecast.

FIRE WEATHER
Issued at 215 PM EDT Mon Apr 21 2025

With high pressure remaining in place, the dry weather pattern will continue this week. An onshore wind, becoming gusty each afternoon and evening due to the inland-moving sea breeze, will combine with lower relative humidity values and produce sensitive fire conditions. Near critical fire conditions may develop over far interior locations.
