Area Forecast Discussion National Weather Service Melbourne FL 930 PM EDT Sun Sep 26 2021

UPDATE.

A quiet, comfortable night is in store for ECFL with a large autumnal high pressure ridge covering much of the eastern CONUS including FL. Diurnal CU/SC field has moved either west of CWA or dissipated with the loss of insolation. Light NE flow in place in the process of weakening as local air mass decouples. Dry surface (L-M60s TDs) and mean airmass (PWATs around 1.0" north-central and <1.5" south will set the stage for widespread overnight lows in the M-U60s with a few L60s possible over rural northern and interior sheltered areas Forecast is in great shape. no changes needed.

AVIATION. VFR/SKC.

MARINE. A gentle to moderate NE breeze will continue to produce seas around 3ft near shore and 4-5ft away from the coast. The inherited CWF looks fine with some minor cosmetic adjustments.

Cristaldi/Watson

PREV DISCUSSION. (Issued 400 PM EDT Sun Sep 26 2021)

Monday-Tuesday . High-amplitude ridging in the mid-upper levels will take hold of the center CONUS while a longwave trough axis lurks just offshore of the eastern seaboard, maintaining the north to northwest flow of dry and stable air into FL, just above a strong subsidence inversion at around 5000 ft AGL. In the low levels, high pressure over the SE U.S. will keep northeast winds, which will bring in occasional marine stratocu from the Atlantic. However, beyond these clouds, the atmosphere will be too dry to support any rain mention with the exception of the Treasure Coast on Tuesday, where the base of the subsidence inversion lifts by a couple thousand feet, which would support the development of a few showers.

Min temps in the mid-upper 60s for most and closer to 70 across the barrier islands. Max temps mid 80s at the coast and upper 80s to near 90 inland, but dewpoints in the 60s will still make it feel pretty comfortable out.

Wednesday-Thursday . Mid-upper level ridge axis will slide eastward toward the Great Lakes and the SE U.S. while strengthening at the same time. This will prolong this stretch of mostly dry weather, but with occasional pockets of higher low-level moisture advecting in from the east with the onshore flow, can't rule out a few marine showers making it onshore. Will maintain a dry forecast for now, but it's possible that some precip mention (but no thunder) will need to be added later.

Not much change in high temperatures with mid-upper 80s along the coast and around 90 inland. Min temps will start to moderate slightly to the upper 60s to low 70s as the onshore easterly flow deepens toward Thursday.

Friday-Saturday (modified previous) . There is uncertainty in the forecast at the end of the week and early next weekend, though the trend has been for increasing rain chance as the deep ridge over much of the eastern CONUS (from Great Lakes to FL) breaks down with a weak backdoor front moving across Florida Friday afternoon into Saturday.

This front brings in higher moisture as forecast soundings show 1.30"-1.50" PWATs across the area, with rain chances increasing to 20-30 percent Friday and Saturday. Deep ridging is forecast to develop over the Deep South, trapping large amounts of dry air in the mid/upper levels over FL. Virtually all of the moisture is below 850mb in forecast soundings. Models also show an increase in the pressure gradient, with breezy east winds along the coast and Atlantic waters. So while the trend is wetter, the pattern setting up typically produces scattered fast-moving showers and a storm or two throughout the day.

Afternoon highs in the upper 80s, and some inland spots could get up to 90 degrees. Morning lows in the low to mid 70s.

AVIATION. VFR prevailing through Mon afternoon. Winds will slightly increase late this afternoon up to 12 kt but subside to light and variable for the rest of the night.

MARINE.

Monday-Friday (modified previous) . Generally good boating conditions are expected across the local waters for much of the upcoming week. High pressure north of the area will maintain northeast to east- northeast winds around 10 knots. Seas 3-4 feet on Monday will diminish to 2-3 feet Tuesday through Thursday.

By Friday, seas will build to 4-5 ft as swells from distant Hurricane Sam arrive across the local waters. E/ENE winds are expected to increase to 10-15 kt across the waters.

HYDROLOGY. The St. Johns River at Astor/ASTF1 is forecast to remain within Minor Flood Stage, between 2.3 to 2.4ft through mid week as a period of north winds should keep the water level higher there. At Geneva above Lake Harney/GENF1, the river is forecast to slowly recede in the coming week but will remain within Action Stage.
