Residents in Orlando and surrounding areas are advised to bundle up as a Cold Weather Advisory remains in full swing early this morning, except in coastal Martin County. According to the National Weather Service Melbourne FL, wind chills are expected to hover in the mid-20s to mid-30s, as a Freeze Warning is also effective for Lake and Inland Volusia counties until 9 AM EST.
With high pressure gaining strength in the western Gulf and an upper-level trough cutting through Florida, today's temperatures will struggle to climb above 12 degrees below the usual for this time of year. Very dry air across central Florida will keep PWATs well below 0.5, with minimum RH values between 25-30%, as mentioned in the weather service's discussion, pointing to an extended period of cooler climate.
Sailing conditions, too, are forecasted to stabilize throughout the day as the violent seas up to 6-7 ft over the Gulf Stream start to subside. However, mariners should exercise caution as northwesterly winds are poised briefly to strengthen to 15-20 kts after sunset into early Thursday morning, mainly north of Sebastian Inlet. A respite is expected later in the week with lighter offshore winds and calmer seas.
On the fire weather front, the risk remains elevated through Thursday due to persistently dry conditions and moderately strong winds. Conditions will be particularly sensitive this afternoon," the weather service cautions, with winds forecast around 8-12 mph and relative humidity dropping sharply to 25-30%. Thankfully, the outlook begins to improve by Friday with lighter winds and ascending moisture contributing to a less critical fire environment. For the aircraft services, VFR conditions will be dominant, courtesy of clear skies and decreasing winds tonight.
Orlando area denizens can anticipate a slight upturn in temperatures as we approach the weekend, with a warming trend pushing thermometer readings to around the seasonal average by Friday. However, the forecast hints at a cold front sweeping through by Saturday evening, which could usher in scattered showers and a brief resurgence of brisk winds. After its passage, a high-pressure system is predicted to reign over the southeast US, leading to onshore flow and highs resting comfortably in the mid to upper 70s early next week.
