Rest of Today - Tonight
Made a few adjustments to temperatures, bringing afternoon highs down a degree or two in a few locations, but nothing impactful. Still expecting to see afternoon highs reach the M-U80s inland west of I-95, while the coastal corridor tops out in the U70-L80s, maybe even the M70s on the barrier islands thanks to the sea breeze. Southeasterly winds have picked up to 10-15 mph with gusts 20-25 mph along the I-95 corridor, occasionally tipping over 15 mph with gusts close to 30 mph. More of a moderate breeze inland with winds up to around 10 mph, but still on the gusty side at 15-20 mph. Skies have become mostly clear, but a few controlled burns are producing smoke, notably one in west central Brevard County which the southeasterly winds are pushing towards the Orlando Metro. Mid to high level clouds return overnight, as temperatures drop into the 60s.

Thursday...The mid-level ridge builds back over the eastern US between the shortwave trough working its way across New England and a substantial mid-level low bearing down from Canada. High pressure over the western Atlantic starts to shift south in response to a series of low pressure systems developing across the CONUS, dragging the ridge across across east central Florida. This will result in lighter surface flow and increasing temperatures. The sea breeze will be a little more muted, increasing south to southeasterly winds to around 10 mph in the late afternoon and evening. Afternoons highs a few degrees warmer than today, with inland areas in the U80s with a few spots reaching 90, and the coastal corridor in the L-M80s due to the weaker sea breeze. Remaining dry.

Friday - Sunday
High pressure over the western Atlantic will influence the region into the weekend. The mid/upper level ridge axis is expected to continue to flatten over the weekend behind the weak shortwave Thursday and with a major shortwave trough developing to the north over Canada and the Upper Midwest into the weekend. Zonal flow aloft over central Florida is expected to continue through Sunday ahead of the next "cool" front Monday. Dry conditions are forecast with non-mentionable PoPs. However, Global models suggests a few isolated showers may be possible Sunday if a sea breeze is able to develop with increasing offshore flow into Sunday. Temperatures are expected to continue an increasing trend and reach near-record values, mainly at inland locations Friday and into the weekend. Afternoon highs are forecast to reach the mid 80s to lo 90s along the coast and the low to mid 90s inland west of I-95 with lows in the low to upper 60s under mostly clear skies. Offshore flow will continue with the east coast sea breeze developing and pushing inland west of I-95 from the east-southeast at around 10mph at least Friday and Saturday afternoons.

Monday-Tuesday... Global models and ensembles are in good agreement that the next "cool" front will weaken and become diffused as it enters central Florida with upper-level support remaining to the north over the Carolinas. Scattered showers (20-40% PoPs) and isolated lightning storms are forecast to develop and move east-northeast Monday morning to the north of I-4 with showers and lightning storms forecast to move to the south into the afternoon. Rain chances then dwindle into Monday night over land as the "cool" front moves farther east-southeast, before stalling over south Florida into Tuesday. Most of east central Florida is forecast to remain dry Tuesday, although some of the guidance suggests that a few isolated showers will be possible into Tuesday afternoon across the Treasure Coast depending on whether the front nudges back north. Afternoon highs are forecast to reach the mid 80s to low 90s Monday with slightly cooler temperatures Tuesday (upper 70s to low 80s across Volusia and Brevard counties with the mid 80s to low 80s elsewhere. Overnight lows are expected to drop into the mid 60s to near 70 degrees.

Previous discussion... High pressure will remain in control over east central Florida through the weekend, maintaining dry conditions and warming temperatures. Southeast wind flow today 10-14 mph with some higher gusts up to 20 mph. Slightly lower wind speeds Thursday as high pressure ridge axis slips south across the area. Winds become southwest late week into the weekend with sea breeze development along the coast each afternoon. Min RH values will reach critical levels across the interior, falling to 30-35% each afternoon through Sunday. Along the coast, min RH values will hold between 40-50%. Very Good dispersion is forecast this afternoon and generally Good on Thursday.
