Orlando is bracing itself for another scorcher forecast that predicts afternoon thunderstorms and peak heat indices hitting between 104-107 degrees. "Continued hot and humid with peak heat indices 104-107 today," the service noted early Sunday morning. With the humidity comes an increased risk of scattered lightning storms that could bring heavy rain, gusty winds, and of course, dangerous lightning strikes this afternoon, as reported by the National Weather Service.
These weather conditions stem from a "broad upper level ridge across the southern US and SW Atlc" that remains in place, along with "a small weakness in the ridge over FL," the National Weather Service Melbourne FL explains. Furthermore, they note, "Steering flow is weak, esp across southern sections so slow and erratic storm motion will promote very heavy rain with up to 3 inches possible in a short time." Residents should prepare for frequent lightning and gusty winds up to 50 mph possible this afternoon.
Looking ahead to Monday, there's an expectation for an earlier onset of the sea breeze, though some dry air advection is predicted to decrease rain chances along the Treasure Coast to 30-40%. However, higher moisture pockets will support a 50-60% coverage across interior and northern sections. Residents can anticipate similar temperatures, maintaining that humid, heavy-air feeling that's become all too familiar.
As for the marine outlook, generally favorable boating conditions are expected throughout the week. "The Atlantic high pressure ridge axis will remain across south FL today then lift northward across central FL early this week before settling back across south FL mid week," the forecast discussion states. Winds will generally stay around 10 knots or less, with seas mostly steady at about 2 feet—3 feet offshore. For those hitting the waters, be watchful for scattered lightning storms, especially in the afternoon as they can bring gusty winds and lightning strikes.
