New UPDATE, AVIATION, MARINE

UPDATE
Issued at 859 PM EDT Thu Apr 18 2024

High pressure over the western Atlantic nudges slightly southward overnight. Cirrus and mid level stratus drift overhead with skies becoming partly cloudy. Low temperatures fall to range the low to mid 60s. The current forecast remains on track.

AVIATION
(00Z TAFs)
Issued at 859 PM EDT Thu Apr 18 2024

VFR through the period. Light and variable winds become east to southeast as the sea breeze moves inland tomorrow afternoon. The sea breeze may not reach ISM/LEE where light winds are forecast to remain west to southwest throughout the day. Dry conditions persist.

MARINE
Issued at 859 PM EDT Thu Apr 18 2024

Tonight...Southeast winds around 5-10 kts veer southwest as high pressure drifts southward. Seas remain steady around 2-3 ft. No precip is forecast.

PREVIOUS DISCUSSION
Issued at 343 PM EDT Thu Apr 18 2024

Rest of Today-Friday...Not much to talk about other than the well above normal temperatures. Highs are forecast to top out near 90 inland and in the L-M80s closer to the coast. The ridge axis from high pressure over the Atlantic extends across central Florida this afternoon, and will continue drifting towards south Florida where it will settle tonight. Lows tonight in the 60s, except the barrier islands who will be closer to 70. Very light background flow will veer southwesterly to westerly by Friday morning, but for the most part expect variable winds until the sea breeze develops Friday afternoon, shifting winds southeasterly around 10 mph. Afternoon highs will climb into the lower 90s inland and the M-U80s along the coastal corridor. While very warm and well above normal, we're still a few degrees short of high temperature records for the day. Very dry with relative humidity values less than 45 pct west of I-95, and only the barrier islands at or above 60 pct.

Saturday-Sunday... High pressure over the western Atlantic will continue to influence the region. Flow aloft will become zonal Saturday into Sunday with a mid/upper level ridge expected to flatten over the Southern US as a low to the north deepens across Canada and the Upper Midwest. Offshore west to southwest flow will continue with the east coast sea breeze developing and pushing inland west of I-95 from the east-southeast at around 10mph Saturday. Wind fields are expected to increase from the southwest Sunday ahead of a "cool" front which will keep the sea breeze confined near the coast, mainly south of Cape Canaveral. Southwest winds at 10-15mph with gusts to 25 mph are forecast.
Rain chances stay non-mentionable through the weekend.
Plenty of sunshine is forecast Saturday with partly cloudy skies Sunday. Afternoon highs are expected to reach above normal (~5-10 degrees) to near records with temperatures in the upper 80s to low 90s along the coast and the low to mid 90s inland west of I-95. Low temperatures are forecast to drop into the low to upper 60s. Patchy fog is forecast across Lake, Volusia, Seminole, Orange, northern Osceola, and northern Brevard counties Saturday morning, mainly between 5 and 9am where visibilities will have the potential to drop to 1 mile or less.

Monday-Wednesday... Global models and ensemble solutions continue to show the next "cool" front weakening as it enters central Florida with upper level support remaining to the north over the Carolinas.
Moisture is also a limiting factor with forecast soundings showing substantial dry air above 700mb, in addition to PWAT values in the 1.2-1.6" range. Scattered showers and isolated lighting storms are forecast to develop and move east-northeast Monday morning north of I-4, before moving to the southeast into the afternoon. Guidance keeps QPF very low through Wednesday with only 0.05-0.25" forecast Monday. Onshore flow is expected to develop Tuesday afternoon with the front forecast to stall over south Florida into Tuesday. Some of the guidance suggests that isolated showers will be possible into Tuesday afternoon across areas south of the Orlando metro depending on whether the front nudges back north. Isolated showers are possible Wednesday with a shortwave trough forecast to track across central Florida Wednesday coupled with onshore flow and PWATs in the 1-1.6" range.
Afternoon highs are forecast to reach the low 80s to low 90s each afternoon with lows in the low 60s to near 70 degrees.

FIRE WEATHER
Issued at 343 PM EDT Thu Apr 18 2024

An area of high pressure located across the western Atlantic will continue to provide dry conditions across east central Florida through the remainder of this week and into the weekend. Minimum RH values will remain in the 35 to 45 percent range across the interior west of I-95, with a few localized areas across the interior falling to 30 to 35 percent, especially Saturday and Sunday. Along the coast, minimum RH values will remain above critical values in the 40 to 55 percent range. Light winds will become west-southwest tomorrow as the ridge axis shifts southward across the peninsula. The development of the east coast sea breeze and movement inland will cause winds to back out of the east-southeast each afternoon.
Wind speeds are forecast to remain below 15 mph through the remainder of the week. Afternoon smoke dispersion will be generally good to very good on Friday, and very good to excellent Saturday.
