Area Forecast Discussion National Weather Service Melbourne FL 410 AM EDT Mon Mar 30 2020

DISCUSSION.

. Near Record Heat Will Continue Through the End of March .

. Elevated Fire Weather Danger on Tuesday .

Currently . Hi-res model and MOS guidance indicates patchy ground fog is still possible, mainly over the far interior toward Lake County and west of Florida's Turnpike through early this morning. Any fog should once again break up and diminish an hour or two after daybreak with daytime heating. Today-Tonight . Mid-level ridge across the area will begin to shift southward through tonight as mid/upper level trough over the central and southern Rockies shifts eastward into the central United States. Still, the influence of the ridge will continue, by stalling a weak front north of the area, and keeping a hot and dry pattern in place. Weaker and more variable winds expected today, before sea breeze shifts inland and increases onshore flow along the coast. The development of the sea breeze will continue to keep highs limited to the mid to upper 80s along the coast, while inland max temps will reach into the low 90s with Sanford and Leesburg likely reaching their record highs again today (see climate section below). Temperatures tonight will remain very mild with lows in the mid to upper 60s.

Tuesday-Thursday . Nil changes to the forecast surrounding the upcoming FROPA. Potent, fast-moving short wave trough with an attendant compact low pressure center will bypass Florida to the north Tue-Tue night. The system will drag a cool front SE through the central peninsula Tue night through early Wed morning, clearing the SE CWA by mid-morning. Increasing, gusty SW winds will make for another hot day areawide Wed, with highs reaching the U80s-L90s areawide, with a band of showers moving quickly into the CWA in the evening, with isolated activity possibly reaching north Lake/Volusia around sunset.

While TS are still not being forecast, given the mean steering winds of 40-50 mph, there could be some gusty winds with the more robust activity. Precip will pretty much be SE of central FL buy sunrise, with a few straggling showers possible over the far SE for another hour or two early Wed morning. Cooler maxes Wed (L80s north to U80s south), but there are still about 1-2 cats above normal for most of the CWA. Cooler/drier air takes a brief hold Wed night with M-U50s inland and L60s along the coast. However boundary layer winds are already veering onshore by Sunrise Thu, which will modify any further CAA. U70s for most of CWA Thu, with M70s for the Volusia Coast and L80s from Western Lake County southward across the Lake O region.

Friday-Sunday . Florida will lie in zonal, anticyclonic flow aloft through through this weekend between a flat ridge over the southern GOMEX and broad western Atlantic troughing. Weak vort lobes will ride over the top of the ridge this weekend, with the guidance hinting at perhaps a slightly more robust trough aloft Sun. However, given what we've seen happen to NBM-advertised numbers out past day 4 in this current pattern, for the time being feel it's better to cap POPs at 20 percent for next weekend.

Temps will be near to slightly above normal, with Sun likely being the least warm of those 3 days, given the increase in cloud cover. Maxes in the U70s near the coast and L80s inland. Mins in the L60s, except U50s inland Fri night.

AVIATION. Patchy ground fog may produce brief IFR/MVFR conditions early this morning, mainly over the interior. Otherwise VFR conditions expected with light and variable winds, becoming easterly and increasing up to 10-15 knots along the coast as the east coast sea breeze forms and moves inland.

MARINE. Today-Tonight . Favorable boating conditions expected. Area will be between two weak high pressure centers over the Gulf and west Atlantic, which will keep relatively light (around 5-10 knots) and variable winds over the waters in the morning. Into the afternoon as the east coast sea breeze forms and moves inland, winds near the coast will become E/SE and increase to around 10 knots. Then into tonight, winds will increase to 10-15 knots as the become S/SW. Seas will range from 1-3 feet.

Tuesday-Friday . SW-W winds increase through Tue night, reaching 15kt near the coast and 20kt farther offshore. The offshore component will keep highest seas (5-6ft) well away from the coast, until winds shift to NW-N on Wed. This will allow higher seas (5-7ft) to spread across the outer waters, with 4-5ft near shore. Seas remain 4-6ft through Thu night, falling back to 3-5ft late Fri and 3-4ft Fri night, as winds gradually veer to NE while gradually slackening.

FIRE WEATHER. Hot and dry pattern continues, with poor dispersion values expected across the area due to weaker transport winds in place. East coast sea breeze will develop and shift inland by early afternoon, which will increase onshore winds and keep RH values elevated along the coast, while inland min RH values will fall to the upper 30s to low 40s.

No change to the outlook for Tue, as SW winds increase to 15-20mph and become gusty. RH values will drop into the L40s areawide, with U30s in some locations. Fire Weather danger will be high in spite of min RH values being forecast to remain a little above 35 percent.

CLIMATE.

Leesburg and Sanford are forecast to tie their record highs for today, with Melbourne, Vero Beach and Fort Pierce close to their record highs on Tuesday.

March 2020 Stats/Rankings .

With well above normal temperatures continuing through the rest of the month, we are on track for the warmest March on record for Daytona Beach, Leesburg, Sanford and Orlando.

It should also be the driest March on record for much of the area. However, isolated to scattered showers are currently forecast ahead of an approaching weak cold front into the evening of the 31st, so any additional rainfall before midnight on Tuesday evening could change these current rankings.
