Area Forecast Discussion National Weather Service Melbourne FL 652am EST Thu Jan 23 2025 .PREVIOUS Issued at 442am EST Thu Jan 23 2025 Today-Friday...Weak low pressure is forecast to develop off the southeast FL coast and lift N/NE through the day today and eventually farther offshore through late week as trough aloft approaches and eventually crosses Florida late Friday into Friday night. High pressure will gradually build eastward across the northern Gulf coast through this time, with northerly flow toward the surface persisting across the area and wind speeds remaining somewhat elevated. This will continue to transport colder air into the region, and keep temperatures well below normal through late week. Scattered to numerous light showers mostly persist across the waters and portions of the coast early this morning, with some areas of drizzle also occurring in the stratus across east central Florida. Coverage of lighter showers should begin to increase closer to daybreak and into the morning across east central Florida (PoPs up to 50-60 percent) as S/SW flow off the surface from around 850-700mb continues to transport moisture northward and increases isentropic lift. This light to at times moderate shower activity will then continue through the afternoon and gradually diminish and shift offshore into tonight as drier air builds down into region. Dry conditions then prevail Friday into Friday night. As mentioned previously, colder than normal temperatures will persist through late week. Cloudy, showery conditions will keep highs in the upper 40s to low 50s near to northwest of the I-4 corridor and in the mid 50s to low 60s farther southeast, except potentially reaching the mid 60s along the Treasure Coast. Colder air then remains reinforced into Friday, with highs in the mid to upper 50s across the entire area on Friday. Nighttime/early morning temps will remain very chilly, with lows tonight in the 30s and 40s. Temps may reach near freezing with areas of frost developing in normally colder locations across far northern Lake and northwest Volusia counties. Northerly winds around 10 mph will produce wind chill values as low as the mid 20s and 30s across much of the area. A Cold Weather Advisory has been issued for Lake, Volusia, Seminole and Orange counties tonight through early morning Friday where lowest wind chill values of 25 to 30 degrees are forecast. Coldest night will be into Friday night/early Saturday, where freezing temperatures and frost will be more likely for areas northwest of I-4, with mid 30s to upper 30s then forecast for much of the rest of east central Florida, except low/mid 40s along the immediate coast, south of the Cape. Wind chill values as low as the mid 20s to mid 30s are forecast for early Saturday morning, and another Cold Weather Advisory will likely be needed for a larger portion of east central Florida. Saturday-Thursday...High pressure builds into the southeast this weekend keeping dry conditions in place and veering low level winds onshore. This will lead to a gradual rise in temperatures after the cold start to Saturday. Highs will still be below normal into Saturday afternoon, reaching into the 60s, except upper 50s northern Volusia County. Lows Saturday night then not as cold, but still in the 40s across much of the area, and upper 30s across normally colder locations northwest of I-4. Highs on Sunday will be a little closer to normal, in the upper 60s to low 70s, except low/mid 60s along the Volusia County coast. Lows then fall to the mid 40s to mid 50s Sunday night. Warming trend then continues into next week as high pressure settles farther southward across the area. Mostly dry conditions look to persist through the extended, with highs either near to slightly above normal in the 70s and lows in the upper 40s to 50s. Marine Issued at 442am EST Thu Jan 23 2025 Hazardous boating conditions will persist across the waters through late week. Weak low pressure developing off the southeast Florida coast will increase northerly winds to 20-25 knots across the adjacent Atlantic today, with a strong to fresh northerly breeze then persisting through Friday into Friday night as low shifts toward the north-northeast. Seas will range from 7-10 feet today, and decrease slightly across the nearshore waters to 4-6 feet on Friday, but still remain up to 7-9 feet in the gulf stream waters. A Small Craft Advisory continues across the entire waters through today into late tonight, and then persists for the offshore waters through Friday. However, additional extensions will likely be needed through at least Friday night. High pressure then builds into the southeast U.S. this weekend and farther southward across the area early next week, with boating conditions gradually improving. Winds become E/NE into the weekend and diminish to 10-15 knots Saturday and 5-10 knots Sunday. Seas will still be up to 5-7 feet over the gulf stream early Saturday, but will fall to 3-5 feet into Saturday night and 2-4 feet Sunday. Fire Weather Issued at 442am EST Thu Jan 23 2025 Friday...A drier airmass building southward into the area will lead to min RH values as low as the upper 30s to low 40s along and north of the I-4 corridor Friday afternoon. Northerly winds will be around 10 mph across the interior and around 15 mph and gusty along the coast in the afternoon. NOAA Melbourne FL Office: Watches - Warnings - Advisories FL...Cold Weather Advisory from 3am to 9am EST Friday for FLZ041- 044>046-141-144. AM...Small Craft Advisory until 4am EST Friday for AMZ550-552-555. Small Craft Advisory until 7pm EST Friday for AMZ570-572-575. |
