Tonight-Sat...Satellite imagery at 1 pm ET showed a thin layer of high clouds over east central FL and also the approaching cold front. The front was extending from the eastern Gulf towards central FL panhandle and over central South Carolina. Ahead of it, local Doppler radars indicated that light to moderate showers were accompanying this front. When we compared these observations with short term models, the latter are on track with their depiction. So with that, the line of showers will continue to move towards the southeast and move across northern FL this afternoon. It will then approach Lake and Volusia counties early this evening and reach Orange Co after 7 pm. Accumulations should stay below a tenth of an inch. After reaching the Cape and Osceola co, showers will start to lose intensity, and only near 20% chance of light showers is expected to continue to move south. Rain should end by 5 am and be replaced with partly cloudy skies.

Winds will be veering tonight from SW to W by midnight and stay from the west through Sat. Speeds will increase behind the front to 10-15 mph late Sat morning. Temps tonight will not be as cold as this morning, as these are expected to drop to the mid 40s from Lake/Volusia to Okeechobee counties except Orlando metro and coastal Brevard to Martin where it will stay at near 50. Highs on Sat will feel cooler than today, as temps stay below 68F.

Saturday night-Monday...Winds easing into Saturday night, as high pressure continues to build into the area. However, winds veering from W to NW will increase cold air advection, making Saturday night into Sunday morning the coldest night of the week. Temperatures falling into the upper 30s to low 40s for most of east central Florida, except for northern Lake and Volusia Counties where temperatures in the mid 30s will be possible and along the immediate coast as barrier islands remain in the low to mid 40s. Patchy frost will also be possible for northern Lake and Volusia Counties.

Remaining dry Sunday and Monday, with building high pressure. Sunday, highs only reaching the low to mid 60s across the area. Then, a warming trend begins on Monday, as highs warm to the mid to upper 60s.

Tuesday-Friday(modified previous)...High pressure continues to remain in place across the region as it extends eastward into the west Atlantic. This will keep a dry pattern in place, with temperatures slowly increasing through the period as a light low level onshore flow persists. Highs on Tuesday in the mid 60s to low 70s will gradually rise to the mid to upper 70s by Thursday and the upper 70s to near 80 on Friday. Overnight lows will also show a warming trend from the 40s to low 50s Tuesday night to the mid to upper 50s on Thursday night.

Tonight-Sat...As a cold front starts to approach the local waters late this afternoon into tonight, southerly winds will increase over the Volusia waters to near 15 kt and increase to near 20 kt from the southwest tonight. A Small Craft Advisory will be in effect for the offshore waters with seas reaching 4-6 ft late tonight. For the nearshore, operators of small craft should exercise caution as winds reach 15-20 kt. Seas will remain in the 2-4 ft range.

On Sat, as the front pushes south of the Treasure Coast, winds will slightly increase through the day across the waters but staying at near 20 knots. Seas 4-6 ft offshore.

Saturday night-Monday...Winds easing and veering NW Saturday night, then becoming W around 10kts of less on Sunday. Then, increasing slightly to around 10-15kts on Monday, as winds veer NNW. High pressure building into the area will keep rain chances and hazardous boating conditions out of the forecast, with seas 3-5ft Saturday night becoming 2-4ft through the period.

Tuesday-Wednesday...High pressure influence persisting, as a period of onshore flow develops. Winds 10kts or less through midweek, with seas 1-3ft.
