Today - Tonight
The high pressure ridge centered along/offshore the SE US Coast will continue to drift SE, with it's axis/western flank eventually reaching central FL tonight. Patchy/shallow dense fog which developed around midnight N/W of the I-4 corridor will quickly burn off post-sunrise. Expect a dry/warm day with slightly warmer max temps in the U70s, with a few inland spots topping out around 80F. Light SE winds will back slightly during the afternoon as the ECSB develops and pushes inland. Winds go light/calm again tonight as the synoptic flow veers to light southerly, allowing mins to fall back into the U50s, with normally cooler inland spots reaching the M50s.

Saturday - Sunday
.Weekend forecast remains relatively unchanged as surface high pressure settles just off the NE FL coast on Saturday ahead of the region's next frontal passage on Sunday. Nil rain chances for tomorrow, with forecast PW still sitting below 1.00". Position of surface high will allow south/southeast winds to shift southwesterly through the day, which will in turn, send afternoon highs toward 80 degrees, with above normal lows in the low 60s Sunday morning.

Models remaining in good agreement with the arrival time of the next cold front early Sunday morning, although the ECM pushes the front through more quickly, clearing most of the area in the mid afternoon. Have geared rain chances toward this solution, with Probability of Precipitation near 30% across the northern forecast area prior to sunrise on Sunday, then sliding down the peninsula through the mid afternoon with most if not all shower activity clearing the southern Treasure Coast by sunset.

Behind the front, winds will veer northwesterly and advect cooler air into east central FL. Highs Sunday will be limited to the low/mid 70s across the north due to increasing cloudiness, with areas near Lake Okeechobee still reaching the low 80s. Sunday night into Monday though will be noticeably cooler, with lows returning to the upper 40s to low 50s.

Monday - Friday
Another high pressure ridge will sink across the region behind Sunday's frontal passage. once again extinguishing any rain chances on Monday and Tuesday. Cooler and drier air returns, with highs Monday hovering near 70 degrees and overnight lows dipping again to the upper 40s/low 50s. A warming trend will initiate Tuesday, with temps returning to the mid/upper 70s in the afternoon and nighttime lows increasing to the low/mid 60s. The most popular travel day on Wednesday will feature another cold frontal passage, although expecting minimal travel impacts here in east central FL as precipitation potential will remain less than 30% areawide. Thanksgiving Day will be pleasant with no rain in the forecast and near normal temps, with highs in the low 80s and lows dipping to the low 60s.

Today - Tonight
Minimal wind chop with a decaying long (9-10s) period swell of 3-4FT will continue to gradually subside through tonight. The current forecast shows a very small area of 5FT seas out near 60NM today, given that combined seas at buoys 41009/41010 remain in the 4-4.5FT range.

Saturday-Tuesday...Generally good boating conditions prevail this weekend and into early next week, with only a brief wind surge across the local Atlantic waters with the next frontal passage on Sunday. Ahead of the front, south winds will become southwesterly, then shifting northwest, increasing up to 20 kts early Sunday, then quickly diminishing to 10-15 kts by Monday. Seas of 3-4 ft will build up to 3-5 ft with this surge, but diminish back to 2-3 ft early next week. Frontal passage will bring low end chance for light showers across the Atlantic waters.
