719 FXUS62 KMLB 201731 AFDMLB Area Forecast Discussion National Weather Service Melbourne FL 1231 PM EST Thu Nov 20 2025 ...New AVIATION... .KEY MESSAGES... Issued at 155 AM EST Thu Nov 20 2025 - Patchy fog is expected to form for the next few mornings with some locally dense fog possible. - There is a Moderate Risk of life-threatening rip currents at Atlantic beaches. - Warm and mostly dry weather over the next week. && .DISCUSSION... Issued at 155 AM EST Thu Nov 20 2025 Today-Sat...Weak high pressure will remain in control of our local weather. Light winds in vicinity of the low level ridge axis and precip water values 1" or less will maintain warm and dry conditions. A daily afternoon sea breeze will enhance the onshore flow slightly along the coast, up to 10 mph. There will be some high (cirrus) clouds streaming E to SE across the area due to moistening in the 250-300mb layer. Otherwise, only scraps of lower level fair weather cumulus expected. Max temperatures will remain above normal in the low 80s coast and low-mid 80s interior. Conditions will be favorable for patchy fog each morning under light winds, mostly clear skies and full recovery of RH. Sun-Thu...Models are in agreement that a weak cold front pushes through Sunday bringing a wind shift out of the north, little cooling and no rain. The high pressure to the north will steadily move east over the Atlc resulting in a quick veering of wind flow, out of the southeast by Tue and south southeast Wed. This will keep temperatures above normal in the low to mid 80s. Cannot rule out isolated showers pushing onshore from the Atlc Tue-Wed but most areas will remain dry. The next cold front is forecast to approach around Thanksgiving Day but great uncertainty on how quickly it approaches and where it initially stalls. At this point, it is looking like a mild to warm Thanksgiving with some small shower chances possible. && .MARINE... Issued at 155 AM EST Thu Nov 20 2025 Favorable boating conditions are forecast through at least Saturday as high pressure remains in place over the local Atlantic. Light and variable winds turn onshore near the coast each afternoon up to 10 knots, enhanced by the local sea breeze circulation. A weak front pushes through Sunday with NW flow veering N/NE. Winds veer E/NE Mon around high pressure to the north. Seas 1-2 FT through Sat then up to 3 FT in the Gulf Steam Sun-Mon. && .AVIATION... (18Z TAFs) Issued at 1223 PM EST Thu Nov 20 2025 Afternoon LAV guidance lends increased confidence to FG conditions overnight tonight into early Friday morning. Have included prevailing MVFR VIS for all but the Treasure Coast terminals by 7-9Z, with TEMPOs for IFR through around 13Z. It`s possible LIFR VIS will occur at times, especially along and north of the I-4 corridor. The Treasure Coast appears the least likely to see significant impacts. However, have included a prevailing 6SM at those terminals, given the threat for at least patchy FG/MIFG across east central Florida. FG will need to be monitored with future updates, as it is notoriously difficult to forecast. While light winds and the presence of high pressure near the Florida peninsula typically support FG, there was very little observed early this morning. Regardless, light and generally easterly winds look to prevail through the TAF period. && .PRELIMINARY POINT TEMPS/POPS...
