Area Forecast Discussion National Weather Service Melbourne FL 642am EST Wednesday Feb 19 2025 .PREVIOUS Issued at 421am EST Wednesday Feb 19 2025 Today - Tonight Isolated coastal showers will continue to be possible (rain chances around 20%) in the low level southeast flow through early this morning. Then expect increasing rain chances into the afternoon and evening as a wave of low pressure crosses the northern FL peninsula later today, and drags a cold front through the area tonight. Hi-res guidance continues to show a band of rain (remnants of an MCS), with isolated embedded thunderstorms possible, reaching Lake County and through the I-4 corridor into mid to late afternoon. This activity will then continue to progress east- southeast across the area as it weakens through this evening. Instability is meager, with MUCAPE values forecast around 250 J/kg or less, so any thunderstorm potential will remain limited (around 10-20%). Greatest rain chances, up to 60-80%, continue north of a line from Lake Kissimmee to Melbourne, with Probability of Precipitation 30-50% near to south of this line, except 20% across Martin County. As front moves through, cooler and drier air builds in with rain chances diminishing overnight. Developing gusty southwest winds around 10-15 mph and some breaks in the cloud cover into late morning and early afternoon, should allow highs to reach the low to mid 80s from around the Orlando area southward. However, max temps likely to hold in the 70s farther north of Orlando where increased cloud cover should hold on through the day. Behind the front, temperatures will cool into the 50s across much of the area by daybreak Thursday, except low 60s across the southern Treasure Coast. Thursday-Friday...Conditions forecast to remain dry into late week, with below normal temperatures expected as northerly flow behind the front continues across the region. Highs Thursday only reach the mid to upper 60s from Osceola/Brevard northward and lows 70s across Okeechobee County and the Treasure Coast. Coldest temperatures for the week then forecast into Thursday night, with lows in the mid to upper 30s northwest of I-4 and in the 40s along and south of I-4, except low to mid 50s along the barrier islands of the Treasure Coast and southern coastal mainland of Martin County. Northerly winds around 5-10 mph inland and 10-15 mph along the coast will make it feel even colder, with wind chill values in the 30s to low 40s across much of the area early Friday morning. May even see wind chills fall as low as the upper 20s briefly across far northern Lake and NW Volusia counties. Highs on Friday will even be cooler than Thursday. Max temps forecast in the upper 50s across northern Lake and Volusia counties, and Daytona Beach will actually be close to their record cool high for the day. Farther south highs will be in the 60s. Temps Friday night will not be as cold as Thursday night due to an increase in low level onshore winds. However, it will still be somewhat chilly with lows in the 40s across much of the interior and Volusia coast, and 50s for Brevard County and Treasure Coast. Saturday-Tuesday...High pressure building offshore the Mid-Atlantic coast Saturday will leads to onshore flow and an increase in temps into the weekend. However, highs on Saturday and Sunday will still be a little below normal, ranging from the upper 60s along the Volusia County coast and 70s farther south and inland. Min temps will mostly be in the 50s across the area each night. Saturday looks to remain mostly dry, but rain chances increase slightly into Sunday, up to 30 percent, with passing S/W trough aloft. Some differences in overall Quantitative Precipitation Forecast from the deterministic GFS/ECWMF into Sunday/Sunday night, with the GFS (Global Forecast System) a tad wetter. Drier conditions look to prevail into early next week behind the passing trough, with temps still a tad cooler than normal (highs in the upper 60s/low 70s) on Monday and then a gradual warming trend setting in to Tuesday as max temps reach the low to mid 70s. Min temps continue to fall to the 50s for much of east central Florida. Marine Issued at 421am EST Wednesday Feb 19 2025 Today - Tonight Passing wave of low pressure across the northern Florida peninsula will increase rain chances today, with a few storms possible. This system will then drag a cold front through the region tonight leading to poor to hazardous boating conditions. Small craft should already exercise caution over the offshore waters today for S/SW winds up to 15-20 knots and over the nearshore Volusia waters this afternoon as a surge in N/NW winds is forecast behind the low, up to 15-20 knots. As front shifts south, winds become W/NW up to 15-20 knots across much of the waters tonight. A Small Craft Advisory will go into effect overnight tonight for the offshore waters of Volusia and Brevard County where wind speeds will be closer to around 20 knots, with seas building up to 6 feet. Thursday-Sunday...Poor to hazardous boating conditions then continue into late week, with a fresh northerly breeze behind the front. This will build seas up to 6-8 feet over the gulf stream waters. The Small Craft Advisory expands to include the offshore waters of the Treasure Coast late Thursday morning and then continues through Friday evening. Additional expansions to the nearshore waters may be needed, especially for Thursday night. Winds diminish to less than 15 knots as they veer onshore into Saturday, with seas falling to 4-6 feet in the morning and 3-5 feet in the afternoon. Winds then become N/NW into Sunday around 10-15 knots with seas 2-4 feet. NOAA Melbourne FL Office: Watches - Warnings - Advisories FL...None. AM...Small Craft Advisory from 1am Thursday to 7pm EST Friday for AMZ570-572. Small Craft Advisory from 10am Thursday to 7pm EST Friday for AMZ575. |
