Key Messages:

-Breezy to gusty northeast winds develop midweek and continue into the weekend, leading to hazardous marine conditions

-Dry weather prevails for much of the week, near to below normal temperatures mid to late week

Now-Tonight...A noticeably drier airmass has settled over the peninsula this afternoon, leading to dew points in the 60s across much of east central Florida. West-northwest winds are light, around 10 mph or less, and sunshine is out in full force. We'll see highs peak in the mid 80s before quickly falling into the 70s after sundown. Lows overnight are forecast to reach the low to mid 60s areawide with light westerly winds present.

Tuesday-Wednesday...One more day of near to slightly above normal temperatures is forecast Tuesday before a strong (but dry) cold front arrives on Wednesday. Temperatures in the 60s Tuesday morning will climb into the mid 80s by the afternoon, thanks to mostly sunny conditions. Winds out of the west-northwest will veer easterly along the coast in the afternoon.

A deepening longwave trough is expected to move eastward during the middle of the week. As it does, high pressure quickly fills in behind it over the central CONUS. All this happens in concert with the aforementioned cold front pushing through our area on Wednesday, which will be closely followed by breezy to gusty north winds and cooler, drier air. Wednesday's high temperature forecast falls closely in line with the NBM50, some 5 to 10 degrees below mid October normals. The coolest night of the next seven days is expected Wednesday into Thursday as locations along and north of I-4 reach the mid to upper 50s! Elsewhere, a range through the 60s will be common, and Stuart southward will hold right around the 70 degree mark.

Thursday-Sunday...Thursday and Friday are still forecast to be cooler than normal for this time of year, but a warmup to near normal returns next weekend. High pressure remains in place for the rest of the work week while a weak surface trough forms just offshore of the Atlantic coast by week's end. This, along with a return of some moisture Friday into Saturday, could spark a few onshore-moving showers, especially from Cape Canaveral southward along the Treasure Coast. There is disagreement in the models on how widespread the activity becomes, especially on Saturday, and perhaps how long it lasts into Sunday. For now, this forecast carries slight to low-end chance Probability of Precipitation for southern coastal locations to at least hint at the potential for showers.

Now-Tonight...10-15 kt of offshore wind is forecast with decreasing seas of 2-4 ft. Winds slow to 10 kt or less overnight into Tuesday morning. Mostly dry conditions are expected.

Tuesday-Friday...NW winds Tuesday veer onshore in the afternoon (10 kt or less). A strong cold front is set to arrive late Tuesday night into Wednesday morning, bringing a quick increase in northerly winds. By Wednesday afternoon, N winds 15-22 kt will be gusting as high as 25-30 kt. Boating conditions deteriorate from then on, remaining poor to hazardous into late week. Seas 2-3 ft Tuesday build to 4-6 ft nearshore, 5-8 ft offshore Wednesday afternoon. 9 ft seas (or higher) are possible offshore mid to late week. More formidable rain chances return to the waters Friday into next weekend, especially south of Cape Canaveral.

Hydrology
Issued at 220pm EDT Monday Oct 14 2024

As rainfall from Milton continues to drain through the Central FL river basins, flooding concerns remain, especially along the Saint Johns River. While the point at Astor has shown a steady decline from the crest at 4.81 ft (new record), upstream points continue a gradual climb, with Deland and Lake Harney within Major Flood Stage and Sanford approaching Moderate Flood Stage. Each of these upstream points from Astor are forecast to crest within the 7 to 10 day timeframe, pending any additional rainfall within the basin. Long term flood impacts will occur along the Saint Johns River from Geneva to Lake George.

The Little Wekiva River and Shingle Creek at Campbell have also shown steady declines from the crests observed after Milton; both points are forecast to fall below Flood Stage within the next 48 hours.
