Marine Weather and Tide Forecast for Pomona Park, FL

SHORT TERM
(Friday through Saturday night)
Issued at 319 AM EDT Thu May 22 2025

Broad, negatively-tilted troughing extending from the Great Lakes region through the Mid-Atlantic states and New England will maintain a dry west-northwesterly flow pattern across our region on Friday and Friday night. Surface ridging building southeastward from the Missouri Valley will brief wedge down the southeastern seaboard by the afternoon hours.
An onshore breeze will develop along the I-95 corridor before noon that will keep coastal highs in the mid to upper 80s.
Full sunshine and a dry air mass will allow highs to climb to the upper 80s and lower 90s at inland locations, with mid 90s possible across north central FL. Dewpoints crashing into the upper 50s at inland locations will keep heat index values around or just under actual air temperatures on Friday.

High pressure building over the Tennessee Valley and southern Appalachians on Friday evening will create another night of radiational cooling at inland locations as surface winds decouple before midnight, allowing lows to fall to the 60-65 degree range. A light offshore breeze will keep coastal lows in the 65-70 range early on Saturday morning.

Troughing over New England will be slow to lift northward on Saturday, and a shortwave trough embedded in the deep west-northwesterly flow pattern will traverse the southeastern states on Saturday afternoon and evening.
Deeper moisture should remain to the west and northwest of our area, with high altitude convective debris clouds possibly overspreading inland southeast GA during the afternoon hours that may keep highs closer to 90 degrees.
Otherwise, Atlantic surface ridging will build westward towards the FL peninsula as heights aloft rise, with low level southwesterly flow developing and increasing moisture values across north central FL by late afternoon. Isolated convection could sneak into southern portions of the Ocala National Forest towards sunset, with dry weather otherwise prevailing across the rest of our area through Saturday night. Plenty of sunshine and a lingering dry air mass through the early to mid afternoon hours will allow inland temperatures to soar to the low and mid 90s, while an early afternoon sea breeze keeps coastal highs in the mid to upper 80s. Afternoon dewpoints falling through the 50s and 60s again at inland locations will keep maximum heat index values in the 95-100 degree range.

High pressure will slide off the Carolina coast on Saturday evening, resulting in low level flow veering to southerly.
A light southerly breeze will prevail at coastal locations overnight, yielding lows in the lower 70s. Winds will again decouple early in the evening at inland locations, with fair skies promoting lows in the mid to upper 60s inland.

LONG TERM
(Sunday through Wednesday)
Issued at 319 AM EDT Thu May 22 2025

Troughing aloft will depart New England on Sunday, with ridging building over the Gulf that will result in a zonal flow pattern across the Deep South. Shortwave troughing that will traverse the Deep South on Saturday and Saturday evening will shift offshore, with Atlantic high pressure extending across the FL peninsula creating low level south-southwesterly flow. Moisture levels will increase enough for isolated afternoon and evening convection to develop along mesoscale boundaries such as the inland moving Atlantic and Gulf sea breezes. Plenty of sunshine will allow temperatures to soar to the mid 90s at most inland locations, with an afternoon sea breeze keeping coastal highs in the upper 80s to around 90. Increasing humidity levels will create heat index values of 100-105 during the afternoon hours, mainly for inland northeast and north central FL. Lows on Sunday night will only fall to the upper 60s to around 70 inland and the low to mid 70s at coastal locations.

Troughing will sharpen over the Great Lakes and Upper Midwest on Memorial Day, with Atlantic ridging continuing to extend its axis westward across the FL peninsula. Although low level southwesterly flow will strengthen, afternoon and evening convection developing along mesoscale boundaries should remain isolated to widely scattered in nature, with areas along the I-95 corridor favored by late afternoon as sea breezes collide.
Temperatures will again soar to the mid 90s inland and around 90 at coastal locations, with maximum heat index values climbing to around 105 degrees across inland northeast and north central FL, with values around 100 across southeast GA.
Convection should remain mostly diurnal in nature, with muggy conditions resulting in lows of 70-75 on Monday night.

Deep troughing aloft is forecast to gradually dig towards the southeastern states during the balance of next week.
Southwesterly flow will deepen locally as a frontal boundary approaches our region by midweek, and chances for beneficial showers and thunderstorms will continue to increase across our area. Long-term models differ on how quickly this front will cross our area, and model blends thus yield at least scattered convective coverage through next Thursday. Temperatures in the mid 90s with heat index values potentially approaching Heat Advisory criteria (108-112 degrees) on Tuesday afternoon will gradually cool off by Wednesday and Thursday as cloud cover and rain chances increase. Lows will likely remain in the 70-75 range through at least midweek ahead of a potential late week frontal passage.

AVIATION
(12Z TAFS)
Issued at 643 AM EDT Thu May 22 2025

Patchy inland fog will be possible again Tonight, otherwise prevailing VFR conditions are forecast this period. A few thunderstorms are expected across central FL this afternoon. This activity may come close to KGNV. Due to a fairly weak flow, a weak front moving through, and the east coast sea breeze, wind directions will be fairly changeable this period.

MARINE
Issued at 319 AM EDT Thu May 22 2025

A cold front will move further south of the area this morning, as weak high pressure builds to the northwest. A secondary front will move southeast across area this afternoon into Friday morning. Weak high pressure will build to the northwest Friday afternoon, then to the east northeast Saturday. High pressure will build to the east Sunday through early next week.

Rip Currents: SE GA Low Today, Moderate Friday NE FL Moderate through Friday

FIRE WEATHER
Issued at 319 AM EDT Thu May 22 2025

A much drier air mass will overspread southeast GA and northeast FL today, resulting in critically low humidity values this afternoon at all inland locations. North-northwesterly surface and transport winds this morning will shift to west-northwesterly this afternoon at inland locations, where speeds will remain below Red Flag criteria.
Breezy transport speeds will combine with elevated mixing heights to create high daytime dispersions for locations north of Waycross. Good values are expected elsewhere across inland southeast GA, with increasing high cloud cover this afternoon resulting in fair values for most of northeast and north central FL.

A dry air mass will persist on Friday and Saturday, resulting in humidity values approaching critical thresholds at inland locations during the afternoon hours. Breezy westerly transport winds will again combine with elevated mixing heights to yield high daytime dispersion values for most of inland southeast GA on Friday, with good values forecast elsewhere inland. Breezy onshore surface winds will develop at coastal locations during the afternoon hours. Elevated mixing heights will create good daytime dispersion values at inland locations on Saturday. Westerly transport winds during the morning hours will shift to southwesterly during the afternoon.
