Area Forecast Discussion National Weather Service Melbourne FL 302 PM EDT Tue Apr 7 2020

DISCUSSION.

Tonight-Wednesday . Ridge axis of high pressure over the west Atlantic will shift south of the area, with low level winds becoming offshore into tomorrow. Rain-free conditions mostly expected tonight into Wednesday, but could see a few showers develop and move east- southeast into northern Lake and Volusia counties during the mid to late afternoon where greater moisture will exist. Offshore winds look to be strong enough to either pin the east coast sea breeze at the coast or stop it from forming altogether. This will lead to even warmer temperatures tomorrow with highs near records in the upper 80s to low 90s even along the coast.

Thursday . Low level westerly flow to 15-20 knots at 925 mbs ahead of the next front that will approach on Friday will make for a very warm day across east central FL. High temps should reach the upper 80s across Lake county and around 90 to the lower 90s for the rest of the forecast area. Near record highs are expected at all climate sites except Orlando Intl (MCO) where the record for the date is 96 degrees. Somewhat deeper moisture supporting isolated afternoon convection should remain just north of Lake and Volusia county but will keep a low shower chance in the Lake George area with any activity that develops across N FL in the late afternoon.

Friday . (previous) The global models are in better agreement than 24 hours ago with the previously mentioned cold front's arrival and movement through east central FL. The ECMWF is just a tad faster than the GFS, but both have the front moving into northern Lake/Volusia counties Friday morning with rain chances increasing prior to sunrise across northern areas before increasing across the rest of the area as the front treks southward. The front is expected to be south of Lake Okeechobee by early evening, but lingering moisture behind the front will keep a slight shower chance in across the Treasure Coast/Okeechobee through the evening hours on Friday. Based on the earlier time of arrival of the front, max temps have been lowered (ranging from the mid 70s north to mid 80s across the Treasure Coast). Also with the earlier arrival, prospects for thunder have decreased as instability is forecast to be marginal.

Saturday-Tuesday . (modified) Low-level high pressure builds in just offshore of the SE U.S. coast with upper-level ridging across the eastern CONUS. The southeasterly winds in the low-levels will begin to lift back some of the higher moisture back north with the now stalled front also lifting back north as a warm front. At the same time, an upper-level cutoff low over the southwestern U.S. will induce a surface low to develop near the Red River Valley that will drag a cold front toward central Florida late Sunday night (GFS) or Monday (ECWMF). Both models show the cutoff low dampening as it translates eastward before being absorbed by another trough over the Great Lakes. This will lift the surface low rapidly N/NE near or just west the Appalachians, and how far west/east this occurs will ultimately result in how far southward the front can progress. The ECMWF has the front reaching and stalling out across central FL by Tuesday while the 12Z GFS shows it also approaching the area Monday and stalling across southern sections on Tuesday. With the approach of the frontal boundary and deeper moisture near the area late Monday into Tuesday will have POPs in the scattered range for Day 6 and the new Day 7 forecast.

AVIATION. Mainly VFR. Could see some IFR/MVFR cigs in stratus develop over the far interior near KLEE toward daybreak. However, any cig reductions will be short lived as daytime heating breaks up any of this lower cloud cover within a few hours after sunrise.

MARINE. Tonight-Tuesday . S/SE winds up to 10-15 knots tonight will become W/SW into tomorrow as ridge axis shifts south of the waters. Small craft will need to continue to exercise caution over the gulf stream waters, south of the Cape, through early this evening for seas up to 6 feet. Otherwise, seas will fall to 5 feet or less.

Thursday . Westerly flow to 15-20 knots offshore in the morning will decrease into the afternoon. Seas will range from 2-3 ft near shore to 3-5 ft offshore.

Friday-Sunday . (modified) A cold front is forecast to cross the waters on Friday with a brief period of poor to hazardous boating conditions developing behind it. North-northwest winds will increase to around 20 kt behind the front but will quickly diminish late Friday as the pressure gradient weakens. Seas are forecast to build to 4-5 ft nearshore and 5-6 ft offshore before subsiding Friday night into Saturday. Flow will veer quickly to southerly on Sunday with winds to 15-20 knots near shore and up to 20-25 knots offshore as the pressure gradient tightens ahead of the next front for early next week. This will allow seas to build to hazardous levels away from the coast on Sunday.

CLIMATE. Record highs will be approached the next two afternoons at some locations across east central Florida.

It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. 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. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
