Current-Monday... A cold front will cross the local waters Monday afternoon. Isolated showers are forecast through Monday afternoon. West-southwest winds around 8-14kts will build seas to 1-2ft with up to 3-4 ft in the offshore waters (20-60nm).
Tuesday-Thursday... (Modified Previous Discussion) The aforementioned cold front will stall across South Florida's waters and the Keys early Tuesday before diminishing. Behind the front, conditions dry out as an area of high pressure builds across the southeastern US. Expect northwest winds on Tuesday, with speeds generally between 10 to 15 knots. On Wednesday, a reinforcing frontal boundary will push southward across the Florida peninsula and local Atlantic waters, resulting in the northwesterly winds increasing to 15 to 25 knots across the local Atlantic waters. Winds will veer to out of the northeast on Thursday and decrease back to 10 to 15 knots. Seas 2 to 4 feet on Tuesday, increasing to 4 to 8 feet on Wednesday due to the winds, and then decreasing slightly to 3 to 7 feet on Thursday.

Tonight/Mon...The cold front remains well to the west near TLH late this afternoon but there is a pre-frontal trough or outflow boundary pushing into northern sections sparking scattered showers and isolated storms and a temporary wind shift out of the W/NW. This activity will continue to push E/SE into this evening into Osceola and Brevard counties and offshore. A brief downpour and gusty wind up to 40 mph is possible with the stronger cells. The front will slide into central FL overnight and early Monday and bring isolated showers. The HRRR (High-Resolution Rapid Refresh) shows stratus and fog expanding from the FL Gulf coast reaching southern and interior sections late tonight. The low clouds could linger much of Monday morning and even when they diminish, considerable mid and high clouds will keep skies mostly cloudy. Not a lot of cooling immediately behind this front. Max temps will range from the upper 70s Lake and Volusia to the lower 80s south with a few mid 80s possible.
Tuesday... (Modified Previous Discussion) The aforementioned cold front is forecast to stall across South Florida and the Keys early Tuesday before diminishing, with the Euro showing a faster decay of the boundary than the GFS. At the surface, a high pressure system over the central US will gradually strength and shift eastward across the southeastern US behind the front. Locally, northerly winds will help filter in the drier, cooler airmass into east central Florida. Thus, rain chances will be less than 10 percent with lower relative humidities as well.
Afternoon highs on Tuesday will fall closer to climatological normal for this time of year, with temperatures in the low to mid 70s across east central Florida. Overnight lows on Tuesday in the upper 40s to low 50s.
Wednesday-Saturday... (Modified Previous Discussion) Dry conditions are forecast across east central Florida through the remainder of the period. A mid-level trough will sweep across the southeastern US on Wednesday, pushing a reinforcing frontal boundary across the peninsula at the surface, with even drier and cooler air forecast to push in behind the front. As a result, clearing skies are forecast across the area Wednesday through Wednesday night. As the surface high shifts eastward towards the Atlantic, onshore flow will return Thursday into Friday, leading to some increasing moisture across the area and therefore increasing cloud coverage.
Coolest temperatures are forecast on Wednesday as a result of the reinforcing boundary, with afternoon highs in the low 60s to low 70s and overnight lows in the low 40s to mid 50s. Temperatures will then gradually warm through the remainder of the week into the weekend, with afternoon highs in the mid 60s to mid 70s on Thursday and in the low 70s to low 80s Friday and Saturday. Overnight lows in the mid 40s to upper 50s on Thursday and in the low 50s to mid 60s Friday and Saturday nights.
Issued at 231pm EST Sunday Dec 3 2023 The Saint Johns River at Astor is forecast to continue a very slow decline this week. The river is forecast to remain within Minor Flood Stage through mid week, but could fall into Action Stage later in the week.
