Marine Weather and Tide Forecast for Valparaiso, FL

DISCUSSION
Issued at 111 PM CDT Mon May 18 2026

An upper ridge builds across the extreme southeast states through Tuesday then weakens going into Thursday before rebuilding late this weekend. A large upper trof pattern located mostly over the western half of the CONUS eventually progresses mostly across the interior eastern states through this weekend, and in the process maintains a southwesterly flow aloft over the forecast area. A series of shortwaves move through the southwesterly flow over the area meanwhile, which along with a weak sea breeze circulation developing each day will lead to convective development. That said, subsidence effects associated with the nearby upper ridge are anticipated to make for a mainly dry day on Tuesday, then going into Friday tend to limit convective development over eastern portions of the area. Have gone with slight chance to chance pops on Wednesday for much of the area, then for Thursday will have slight chance to chance pops mainly west of I-65.

While the upper ridge is anticipated to rebuild going into the weekend, it also becomes oriented mainly across the Florida peninsula. Predominately likely pops return for Friday through Sunday over western portions of the area, while further to the east pops gradually trend to chance pops. Patchy fog will be possible late tonight and late Tuesday night, with the potential for some localized thick fog. A moderate risk of rip currents is expected through tonight, then a High Risk follows for Tuesday. A moderate risk is anticipated for Wednesday with a low risk for Thursday and Friday. /29
