As Orlando residents wind down their holiday weekend, the National Weather Service Melbourne FL has alerted the area to a weather pattern that includes lightning, wind gusts up to 50 mph, and heavy downpours. In a statement released early this morning, it was noted that these conditions are a result of a persistent moist airmass lingering over the peninsula, with scattered to numerous showers and storms forecast throughout the work week. Additionally, with temperatures creeping back into the lower 90s, tropical humidity is set to push peak heat indices into the oppressive range of 100 to 105 degrees on most afternoons.
Today's forecast is largely influenced by Tropical Storm Chantal's movement onshore along the South Carolina coast and its northward progression throughout the day. The shifting atmospheric patterns are expected to allow for a sea breeze collision, particularly favoring the eastern portions of the peninsula later this afternoon. According to the National Weather Service, this weather activity is expected to have a 70 percent probability over the I-4 corridor. At the same time, the Treasure Coast may experience a lower chance of rain and storms. Orlando and the surrounding areas should brace for the potential of experiencing frequent cloud-to-ground lightning and conditions that could support localized flooding, especially in areas that are already well-saturated or have poor drainage systems.
As the new week kicks off, the Atlantic ridge axis is projected to continue its northward journey across Florida. This movement should result in another round of southwesterly winds and pinned east coast sea breezes, which translates to a persistent 50-65% chance of rain on both Monday and Tuesday afternoons. This pattern not only heralds the recurring prospects of lightning and gusty winds but also primes the environment for more heavy downpours, as activity may fade overnight.
The remainder of the week is looking to stay wet, with the surface ridge axis holding its ground across the state. From Wednesday to Saturday, sea breeze collisions are expected to provoke increasing rain chances each afternoon into the evening hours. Maintained a 60 to 70 percent chance of rain and up to a 60 percent chance of storms due to increasing moisture across the peninsula through the end of the work week, the National Weather Service explains. Warm and muggy conditions are expected to persist into the weekend, with daytime highs anticipated to range from the upper 80s to the low 90s, and overnight lows settling in the low to mid-70s.
Mariners, meanwhile, can expect improved conditions as the Atlantic high moves northward and builds across the local waters. Notwithstanding the build of high pressure, a moist airmass fostering an active pattern remains in place. Boaters should particularly take heed of forecasted convective patterns that could lead to gusty winds and heavy downpours, especially prevalent in the late evening and overnight hours as they intersect with the southwesterly flow from the peninsula.
