Area Forecast Discussion National Weather Service Melbourne FL 405 AM EST Mon Dec 9 2019

DISCUSSION. Today-tonight . An expansive area of high pressure over the northwest Atlantic this morning will shift east. It will then stretch southwest toward the Florida peninsula and Gulf of Mexico. Southeast winds this morning will veer from the south in the early afternoon, and vary between SE to S tonight. PWAT values will stay near one inch today and increase to around 1.3 inches later tonight. As the ridge positions itself over central FL, some patches of moisture will stream towards the Treasure Coast and adjacent waters late tonight. At the same time, wind go calm late tonight across areas north of Orlando and patchy fog could develop after midnight through early morning. Temps today will climb to the lower 80s and drop down to the lower 60s late tonight across the interior and mid 60s along the coast.

Tuesday-Tuesday night . Scattered showers will remain possible through the morning hours on Tuesday across the Treasure Coast before flow veers keeping showers offshore. Afterwards, a very warm day by December standards is expected with southerly flow remaining in place. Highs are forecast to be roughly 10 degrees above normal for this time of year, which may threaten a record high at Sanford, which stands at 85 degrees from 2013. Interior locations should reach the 84-86 degree range, and the Atlantic seabreeze will keep highs a couple of degrees cooler toward the coast. The atmosphere will still be pretty dry aloft, but some increasing moisture should allow isolated showers to develop in the afternoon.

By Tuesday evening, our next cold front will be moving into northern Florida, and a disturbance aloft moving in from the southwest out ahead of this front will lead to additional shower development across the area. Overnight lows well above normal with mid to upper 60s inland and upper 60s to near 70 near the beaches.

Wednesday-Friday . The previously mentioned front will enter central Florida during the day Wednesday and then stall out somewhere across the area. Rain chances will increase during this period, especially in the Wednesday night through Thursday night timeframe. Models are still showing a coastal trough developing just offshore, and convergence associated with this trough along with deep moisture and impulses in the flow aloft will keep the highest chances for the coastal counties. Both the ECMWF and GFS are indicating locally heavy rainfall with the models starting to key in on Brevard and Volusia county. However, this is highly dependent on where the front stalls out and will undoubtedly fluctuate in the next several models runs. Due to cooling temperatures aloft, have also included a slight thunder chance for Thursday.

High rain chances continue into Friday with the front still lingering across the area, but it is forecast to lift north through the day as a weak surface low/trough develops over the Gulf of Mexico and starts to take the deeper moisture with it. Forecast will carry 40-50% chances across the area with the higher chances north of Orlando.

Saturday-Sunday . The global models are both showing the surface low/trough over the Gulf lifting rapidly to the north on Saturday with its trailing cold front extending down the U.S. east coast. The GFS rapidly pushes the cold front through the area on Saturday as a mid-level trough moves across the Gulf Coast states. The ECMWF is showing the mid-level trough as well but does not clear the front through the area. Forecast will compromise among the models and advertise a chance of showers on Saturday, but both are indicating dry conditions for Sunday once the mid-level trough axis moves to our east and brings in some drier air.

AVIATION. VFR today. SE winds 5-10 kt today becoming light and variable tonight. Isolated areas could experience fog late tonight into early morning reducing visibilities for some of the terminals, mainly KMCO to KDAB and Treasure Coast (KVRB-KSUA)

MARINE. Today-tonight . A ridge from the northeast will extend towards the local Atlantic waters today, keeping winds less than 15 kt from the SE to S through the night. Seas 3-4 ft across the nearshore waters are expected while offshore will experience 4-5 ft.

Tuesday-Wednesday . Southerly flow will increase to around 10-15 knots nearshore and around 15 knots offshore on Tuesday. Flow will begin to veer late Tuesday night as a cold front approaches and then stalls out across the area on Wednesday. Seas will be generally 4-5 ft but may approach 6 ft well offshore.

Wednesday night-Friday . Deteriorating conditions are expected beginning Wednesday night as northeasterly winds increase north of the stalled boundary. Seas will also begin to build from north to south across the waters Thursday into Friday with combined seas reaching 6 to 8 feet nearshore and 8 to 10 feet offshore creating hazardous boating conditions.

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases.

In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
