Area Forecast Discussion National Weather Service Melbourne FL 446 AM EDT Fri Sep 17 2021

DISCUSSION.

Current-Today . A fairly complex setup with a lot of moving parts has remained in place over the region the past couple of days. Current analysis charts show the remnants of what's left of Post Tropical Depression Nicholas located over Louisiana. Meanwhile, a tropical wave with a 70% chance of development by the National Hurricane Center is situated off the Carolina coasts. Additionally, the western Atlantic high pressure system continues to slowly build and stretch into the eastern Gulf of Mexico which has blocked Nicholas from moving much over the Deep South. Also of note, a mid/upper level ridge continues to build over the eastern Gulf of Mexico which has produced deep southwesterly flow over the area. Thanks to the multiple tropical systems near the area and deep southwesterly flow, above normal moisture continues to advect into east-central Florida. Water vapor imagery shows this well with an abundance of moisture seen upstream moving into east- central Florida from the Gulf of Mexico as Nicholas helps advect moisture eastward. Observed skew-t soundings and SPC mesoanalysis showed precipitable water values (PWAT) well over 2," in addition to, low/mid level RH values around 80%. Guidance shows PWAT values could approach close to 2.3-2.5" later this afternoon, especially over locations across and north of Osceola county.

Much like yesterday, the west coast sea breeze is expected to be more dominate today with a much deeper southwesterly flow compared to the weak and shallow onshore flow on the east coast of Florida. This means that shower and thunderstorm development will likely be a little later this afternoon as the west coast sea breeze collides with the weaker east coast sea breeze and outflow boundaries through this evening. Furthermore, showers and lighting storms will likely form a little farther east than some short term guidance has suggested which models are starting to pick up on in more recent runs. The west coast sea breeze is forecast to pin precipitation development mainly along and east of I-4 as it converges with the east coast sea breeze. The HRRR and NAMnest have started to model this line of thinking well in more recent runs. With that said, scattered-to-numerous showers and storms are expected to form this afternoon and increase in coverage through the early evening hours. With an abundance of moisture in place, moderate CAPE values, and absolutely unstable low-level lapse rates, a few isolated strong storms can't be ruled out. The main concerns with any storms that develop this afternoon will be wind gusts to around 40-50mph, frequent cloud-to-ground lighting strikes, heavy rainfall, as well as, flooding over low-lying areas and where training of storms occur. High temperatures will reach the upper 80s to low 90s this afternoon.

Tonight . Widespread showers and lighting storms will be possible through around midnight before precipitation weakens and pushes offshore with the loss of forcing and daytime heating. Overnight, precipitation will dwindle and remain mainly over the far Volusia and northern Brevard county Atlantic waters as the tropical wave departs the region to the northeast. Drier air will filter in overnight and give way to partly cloudy skies. Low temperatures will reach the low-to-mid 70s.

Saturday-Sunday . A broad low pressure trough extending from low pressure offshore the Carolinas (ATLC Invest 96L) will bifurcate high pressure ridges over the eastern US and the Atlantic. This will produce a rather light/chaotic wind regime dominated by the local sea breezes, with very deep moisture (PWATs 2.0-2.3") leading to high diurnal showers/storm chances this weekend, with slightly lower coverage near Okeechobee on Saturday. Weak steering flow will lead to slow storm motion and locally heavy rainfall totals of 1-3", possibly higher in a few spots.

Not expecting expect much shower activity overnight Saturday. Precip chances will be high again Sunday afternoon and evening with convergent surface flow setting up again. Expect showers and storms to continue into the late evening as easterly flow establishes itself, bringing high chances of onshore moving showers to the coastal areas. Max/min temps fairly close to mid-Sep climo.

Monday-Friday . High pressure dominates the Atlantic basin with the ridge axis extending across the basin west towards Florida, while ample moisture remains in place across the state. Predominantly easterly flow through the long term period, but an upper level trough dipping down the southeast on Thursday will bring light and variable winds toward the end of the week. Onshore flow will favor early development of the east coast sea breeze, with showers/storms developing as it progresses inland. Highest coverage of showers and storms will be inland in the late afternoon. Temps expected to stay near climo.

AVIATION.

VFR conditions will persist throughout the TAF period outside of any convection. High coverage of showers and thunderstorms are expected to develop this afternoon as sea breeze and outflow boundary collisions occur with high moisture in place across the region. Precipitation will dwindle around midnight as showers and storms dissipate and move offshore. Winds will remain light from the south-southwest across inland TAF sites. Coastal locations will see light winds back onshore during the afternoon hours before veering offshore overnight.

MARINE.

Current-Tonight . Boating conditions will remain favorable outside of convection with the Atlantic high pressure system building westward into east-central Florida. Showers and thunderstorms are forecast to develop during the afternoon hours before pushing offshore over the Atlantic waters during the late evening hours. Winds will remain light 5-10kts from the west- southwest during the overnight and morning hours before winds back onshore during the afternoon as weak easterly onshore flow develops. Seas will remain 1-2ft nearshore with 3ft waves possible farther offshore.

Saturday-Tuesday . Presence of the broad surface trough over central Florida will create a variable wind flow at 10kt or less through the period. SW winds early Sat will back to S-SE in the afternoon, aided by the local sea breeze circulation, with the synoptic flow becoming more S-SE on Sun. SE to ESE flow become a little more established Mon-Tue. Seas 1-2ft near shore and 3ft well offshore.
