Marine Weather and Tide Forecast for Indian River Shores, FL

DISCUSSION
Issued at 351 PM EST Sun Jan 12 2025

Current-Tonight... High pressure across the Deep south will continue to build across the Florida peninsula as the high pressure shifts offshore the eastern US into tonight. Dry conditions will prevail through tonight with sunny/clear skies forecast. North to northwest winds generally below 10 mph, will become north to northeast later this afternoon before becoming light to calm overnight. Temperatures will be below normal once again today, with afternoon highs ranging from low to mid 60s across the north, and mid to upper 60s across the south. Overnight lows will generally be in the 40s, with low 50s possible along the coast from southern Brevard southward.

Mon-Mon Night... (Modified Previous Discussion) High pressure gets nudged into the western Atlantic with the approach of the next low pressure system. Increasing moisture across the local area, with forecast PW values ranging from 1.3-1.5", will support rain chances returning to the forecast. There is a medium (30-50 percent) chance of showers Monday and Monday night, starting across the I-4 corridor Monday afternoon, and expanding southward Monday night. Conditions do not favor heavy rainfall at this time. A cold front will get pushed southward into central FL Monday night, with precip chances diminishing into early Tuesday morning. Onshore flow will dominate through the period, with speeds generally 5-10 mph before becoming light and variable overnight. Widely ranging temps on this day in part to thicker cloud cover northward and earlier rain chances. Max temps in the L-M60s north of I-4 with U60s to L70s south thru central Osceola-central Brevard counties, and M-U70s possible southward toward Lake Okeechobee. Temps remain milder into Mon night with mins generally in the 50s, except U40s for portions of north Lake and northwest Volusia counties.

Tue-Sat... (Previous Discussion) The aforementioned cold front slowly exits the county warning area to the south on Tue, but depending on how fast this occurs, we could see a low (20 percent)
chance of showers in the morning along portions of south Brevard and Treasure coast as moisture is slowly scoured out. From here, mainly zonal flow aloft with occasional shortwave impulses traversing the area. Continue to keep conditions mainly dry through the end of the week as surface high pressure remains in control. However rain chances return to east central Florida into the weekend, with a low to medium (20-30 percent) chance of showers Saturday and Saturday night ahead of the next approaching front, mainly from Brevard to Osceola counties northward.

Below normal temperatures will continue through late week, with highs in the 50s and 60s. Temperatures will become seasonable to slightly above normal on Saturday, with highs in the 70s, ahead of the next front. Lows also below normal, generally in the U30s and 40s through mid to late week, with Wednesday and Thursday overnight lows being the coldest. Overnight temperatures become more seasonable into the weekend, with lows generally in the 50 to 60s on Saturday night. Still some patchy frost development may be possible Thu/Fri mornings, particularly north of the I-4 corridor in prone rural wind-sheltered locations.

MARINE
Issued at 351 PM EST Sun Jan 12 2025

Current-Tonight... High pressure will continue to build across the local waters into tonight, providing favorable boating conditions.
North to northwest winds around 10 KT today will become north to northeast later this afternoon before becoming light overnight. Seas will be 2-4ft today, subsiding to 2-3ft overnight.

Mon-Thu... (Modified Previous Discussion) Next front moves into the area Monday night into Tuesday, with increasing moisture ahead of the front, which will support rain chances returning to the forecast. There is a medium (30-40 percent) chance of showers Monday afternoon across the north, and a medium (30-50 percent) chance of showers areawide by Monday night-early Tue. Conditions do not favor lightning storm development at this time. With this next system conditions begin to deteriorate on Tuesday as northerly winds behind this front increase 15-20+ kts and seas building to 7 ft in response. Seas will continue to build to 8 ft into Wednesday before gradually improving Thursday to 3-6ft. Thus, poor to hazardous boating developing Tue-Wed night, and a Small Craft Advisory may be needed.

AVIATION
(18Z TAFs)
Issued at 1245 PM EST Sun Jan 12 2025

VFR prevails thru the TAF. Northerly winds lighten and become variable overnight. Then, winds gradually veer ENE into Mon., generally under 10 kt. VCSH was included for northern sites as a low chance of -SHRA arrives after 15z-18z Mon. CIGs also become SCT/BKN around 5-6kft after 12z Mon. across northern terminals.
