The skies over Orlando are exhibiting a bit of indecisiveness today, with weather patterns grappling with a mixture of factors that could influence storm development. According to the National Weather Service in Melbourne FL, there's diminished confidence in the shower and storm potential due to drier air aloft and a blanket of increased cloud coverage that might just to restrict storm development. "Confidence in shower and storm development has diminished slightly," the National Weather Service noted in their morning aviation forecast, which could affect flyers with plans to take off after 20Z today. However, the weather service has decided not to add temporary flight restrictions but has maintained a cautionary stance with a mention of "VCTS" – that's weather code for a potential thunderstorm in the vicinity.
Despite the uncertainty, pilots should prepare for southwesterly winds across the interior and a switch to southeasterly closer to the coast, courtesy of an expected east coast sea breeze. Interesting to note, however, is the planned sea breeze collision closer to Florida's eastern shores, which, if conditions align just right, could kick-start those showers and storms National Weather Service flagged in their forecast discussion.
For those not soaring the skies but instead grounded with weekend plans, be prepared for the heat to ramp up. The mercury is expected to soar leading into next week, with "heat indices of 105 to 107 degrees continuing into next week," the National Weather Service warns. They advise locals to start planning to stay cool and hydrated now. Early risers in the Treasure Coast and Okeechobee counties witnessed this firsthand with scattered showers and lightning storms this morning. This activity was noted to be moving southward at a pace of 10-15 mph, potentially dampening dawn patrols.
The current weather pattern is largely dictated by an upper-level low over the Florida peninsula that is set to inexorably shift northward, and a surface low skirting off the coast of northern Florida, Georgia, and South Carolina navigating westward. Over the next few days, high pressure from the western Atlantic is expected to extend its influence, promoting a south-southeast wind flow. The forecast for Saturday through Sunday calls for scattered showers and lightning storms to potentially develop in the afternoons, with a "PoP 50-60 percent" chance along and west of I-95 come Saturday. So if you're to make the most of the outdoors this weekend, it might be worth keeping an umbrella handy just in case.
For the sailors and marine enthusiasts, the waters may be mostly cooperative, barring any unforeseen showers or storms. "Favorable boating conditions outside of convection expected through early week," reads the report from the National Weather Service. Still, those taking to the seas should be vigilant for the potential development of convection, especially with the east coast sea breeze picking up in the afternoons, stirring winds to about 10-15 knots, and potentially affecting sea conditions.
