Currently and Tonight...Departure of the early clouds has led to a nice day, with temps rebounding into the 70s. West to NW winds will become light to calm with darkness, and some patchy ground fog will be possible in some spots mainly inland early Tuesday morning. Expect overnight lows in the L-M50s.

Tuesday...A shortwave aloft will pass during the day largely unnoticeable, except for some mid-higher clouds. Temperatures will warm into the 70s with modest W-NW winds.

Wednesday...(Modified Previous Discussion) Despite mostly sunny skies, the northerly breeze will keep max temps in the low/mid 70s through midweek, about 3-5F below average. Cool air advection with the NW breeze Tuesday night will allow a drainage flow to develop over the FL Peninsula that will push Wednesday morning temps into the mid/upper 40s across the interior, and into the low/mid 50s along the immediate coast, which is roughly 5-10F below average. Winds begin to veer onshore by Wednesday night, allowing temps to recover to the low/mid 50s, which is near average for late fall.

Thursday-Sunday...(Modified Previous Discussion) Progressive weather pattern shaping up for the latter half of the week as the 300mb- 200mb jet pattern takes on a strong zonal component. The ridge axis will move off the eastern seaboard by daybreak Friday ahead of a new high amplitude frontal trough pushing across the MS Valley. This trough will push the next cold front through central FL over the weekend. Some disparity between the GFS and the ECMWF (European Centre for Medium-Range Weather Forecasts) models as to the timing of the frontal passage. GFS suggesting a Sat/Sat night event, ECM hinting as a slower, Sun/Monday event. However, neither model indicates much of an impact as the frontal axis takes on a positive tilt as it develops over the Central Plains.

Temps continue to modify into the weekend with winds shifting to due east on Thursday, south/southeast on Friday, south/southwest on Saturday, then due west on Sunday. Limited time for full airmass modification will keep temps largely within 5 degrees of average.

Marine
Tonight and Tue...Current wind and wave guidance keeps an advisory in place overnight, and then will begin to trim back the advisory over portions of the near shore waters early Tuesday with expectations on higher seas being confined over the outer waters and gulf stream by Tuesday afternoon. High tides will have potential for further beach erosion through tonight.

Tuesday Night...Hazardous seas will slowly improve, anticipate Small Craft Advisory conditions to remain in place for much of the local Atlantic waters into early Wednesday. Winds veering from W/NW to N/NW in a gentle to moderate breeze. Seas subsiding to 4-5 feet nearshore, and 5-6 feet offshore.

Wednesday...A strong area of high pressure to build over the Deep South, forcing winds diminish to a light to gentle breeze while veering to due north during the day, then northeast overnight into Thursday. Seas subsiding to 3-4 feet nearshore and from 4-5 feet offshore.

Thursday-Friday...Winds will continue to shift through late week as the high pressure builds into the western Atlantic. Winds become light to gentle from the east by Thursday afternoon. Then, winds shift to south/southwest by late Friday morning. Steady state seas expected, 2-3 feet nearshore and 3-4 feet offshore.

Fire Weather
A drying trend continues through midweek with forecast min RH values inland getting into the lower to mid 30s beginning Tuesday. No rain is forecast at least through the remainder of the work week.

Hydrology
The river level on the Saint Johns River at Astor is forecast to stay in Minor Flood Stage for the foreseeable future. The combination of north winds and higher than normal tide levels downstream is preventing water from discharging at a normal rate, resulting in higher river levels upstream.
