Area Forecast Discussion National Weather Service Melbourne FL 345 PM EDT Thu Oct 21 2021

DISCUSSION. Tonight . One last night of dry conditions across east central FL. A ridge of high pressure extending from the Atlantic towards the southeast U.S. will continue to push away from the local area as moisture starts to filter in. Winds will shift from east to southeast becoming light after midnight. A few light showers will be possible to reach the coastal communities but these are expected to dissipate rather quickly. Elsewhere, partly to mostly cloudy skies with temps dropping to the only the mid 60s across interior rural and staying in the upper 60s for coastal and urban areas.

Friday-Saturday (previous discussion modified) . Light east winds will continue on Friday as high pressure ridge axis remains north of the area. The airmass will modify somewhat as some higher moisture lifts northward from south Florida into the Treasure Coast region and also north of I-4 ahead of a cold front moving into the southeast U.S. These would be the favored areas should any diurnal showers develop (chances 20% or less), but dry air and subsidence aloft should keep most dry again on Friday.

The cold front will push to the southeast and reach the local area on Sat morning with high pressure building back over the southeastern U.S. Winds will quickly veer back onshore, and a tight moisture gradient will setup across the area. Precipitable water will range from 1.3-1.7" with the higher moisture favoring southern areas, and rain chances will follow this gradient with 30-40% across the Treasure Coast/Okeechobee and quickly reducing to near 10% from the Cape northward.

Max temps mid 80s along the coast increasing to the upper 80s to near 90 degrees inland. Min temps in the mid-upper 60s except lower 70s toward the beach communities.

Previous discussions: Sunday-Monday . Deeper moisture will lift north into the area associated with an inverted trough moving toward the Bahamas and south Florida. Increasing onshore flow and convergence with this feature will bring higher rain chances and a few storms, especially along the coast and moreso toward the Treasure Coast and Okeechobee where precipitable water will approach 1.8-1.9".

Monday night-Wednesday . A progressive shortwave trough will move across the OH Valley and toward the Mid-Atlantic, and global models are showing this trough inducing development of a surface low somewhere near the coast of the Carolinas in the Tues-Weds timeframe. We may still have enough moisture for a few showers to develop through Tuesday before some drier air on the backside of this low moves southward into FL. Will advertise 20% showers through Tuesday before drying and mid-level ridging keep rain out of the forecast for Wednesday.

AVIATION. VFR conditions prevail through the TAF period. Through the rest of the afternoon, easterly to south-southeasterly winds 8-12 kt, possibly gusty along the Treasure Coast. A marine shower or two reaching the coast is possible, but VIS/CIG impacts are not expected and coverage is too low for VCSH mention. Tonight, winds become light and variable inland as onshore flow across the Atlantic waters continues to stream SCT040 stratocu to the coast. Friday, models indicating a complicated wind field as the Atlantic high weakens and steering flow becomes light. Generally, southeasterly winds around 6 knots that may become variable at times, especially further north.

MARINE. Tonight . Onshore flow this afternoon will veer from the southeast tonight as the high pressure moves to the northeast of the local waters and will decrease through the night from near 10 kt to near 5 kt. Seas will subside from 2-3 ft to around 2 ft.

Previous discussions: Friday-Saturday . Generally good boating conditions expected to finish up the week and to start the weekend. Light onshore winds will continue through Friday before a cold front moves offshore of the U.S. eastern seaboard into Saturday, pushing the high pressure away from the U.S. Winds will briefly veer southerly Fri. night but will quickly return to onshore by Saturday evening as weak high pressure builds back into the southeastern U.S. Winds generally 10 kt or less through early Saturday before increasing to 10-15 kt late in the day. Seas 2-3 ft expected.

Sunday-Monday . Easterly flow of will continue across the waters as high pressure builds over the western Atlantic and an inverted trough approaches the Bahamas. Speeds of 10-15 kt Sunday will lessen to 5-10 kt on Monday as the pressure gradient relaxes. Seas are forecast to build slightly to 3-4 ft. Increasing moisture from the south will bring higher rain chances, especially south of Sebastian Inlet.

HYDROLOGY. The Saint Johns River at Astor is forecast to remain within Action Stage through at least this weekend.
