Orlando residents can expect a change in the weather as rain chances make a comeback this evening and persist through tonight due to a weak disturbance moving across central Florida. The National Weather Service in Melbourne forecasts that the disturbance developing over the Gulf of Mexico will reach East Central Florida late tonight. This system is bringing in higher than usual precipitable water values, around 1.6 to 1.8 inches, which is well above the climatological 90th percentile for this time of year. These conditions could lead to elevated shower activity, particularly from Brevard and Osceola counties northward, though lightning and heavy rain aren't anticipated given the lack of instability.
Following the disturbance, a cold front will pass through the area, bringing in cooler air and lowering temperatures below typical levels for the remainder of the week. Locals can expect a wide range of temperatures today due to cloud cover and the incoming weather system, with some parts of the region potentially not surpassing the 50s. In contrast, southern areas such as Martin County may experience temperatures close to 80 degrees. However, low temperatures will drop to the mid-40s up north and low-60s down south tonight, according to the National Weather Service.
Marine conditions are set to worsen, with the forecast anticipating poor to hazardous boating conditions beginning early Tuesday through Wednesday. The weather disturbance will cause winds to shift north and increase to 20 knots, starting early Tuesday morning in the Volusia waters and moving southward later in the day. This will lead to building seas, reaching up to 4-6 feet nearshore and 5-7 feet offshore by late Tuesday evening, a signal that advisories for higher seas will soon be necessary.
As we head into Wednesday through Friday, the marine situation remains choppy, with high seas lingering, particularly in the Gulf Stream. However, conditions will gradually improve as high pressure moves towards Florida. This trend is projected to continue through the end of the week, with dry air pushing humidity values down and northerly winds decreasing. However, there is some potential for another weak disturbance that could develop and move across the area around Thursday.
The aviation sector will also feel the effects of this weather pattern, with broken to overcast conditions expected to lower and linger throughout the area, potentially affecting visibility. Flight conditions are forecasted to deteriorate along the front, especially north of Melbourne. Instrument Flight Rules (IFR) ceilings are predicted to develop post-frontal passage and persist into at least midday Tuesday. The outlook towards the weekend remains uncertain, with models disagreeing on another significant weather system's timing and strength, keeping a close eye for any updates on potential warming trends or increased rain chances.
