High pressure across the southern peninsula will maintain west winds and slight seas over the Gulf waters today. The high will sink further south on Friday as a weakening cold front moves south through the waters with some showers and storms possible. West winds ahead of the front will shift to the northwest and north Friday night in the wake of the front, with winds becoming northeast to east on Saturday as high pressure to the north shifts east into the Atlantic. Winds will become southeast to south with speeds increasing to Cautionary or Small Craft levels during Sunday and Monday as the gradient tightens ahead of the approaching cold front, with increasing chances for showers and storms expected as the front moves into and stalls out across the waters through the period.

...Increasing Rain Chances Early Next Week
onight - Next Thursday)... High pressure draped across the southern peninsula this afternoon will move south of the state tonight as a cold front approaches from the north with the front moving into the region during the day on Friday. As the front approaches clouds will increase across the forecast area tonight. It will be a warm and muggy night with lows in the upper 60s to lower 70s.
On Friday the front will move south into the forecast area bringing with it increasing rain chances, first across the Nature coast during the early morning hours, with the showers and possibly a storm or two then spreading south across the remainder of the forecast area during the day. Temperatures on Friday will be cooler especially across northern areas where highs in the lower to mid 70s can be expected with lower 80s central and south. As the front moves to the south, showers will come to an end across the area Friday night as some drier air works it way in from the north with post frontal low temperatures falling into the upper 40s to around 50 across the Nature coast, 50s central zones, and lower 60s across southwest Florida.
During the weekend the frontal boundary to the south will lift back to the north as a warm front as strong low pressure develops over the southern Plains and lower Mississippi valley with some additional showers (probability of precipitation 20%) possible within the moist and unstable air mass. Warm air advection will support warm to hot temperatures with highs on Saturday in the lower to mid 80s, then climbing into the upper 80s to lower 90s on Easter Sunday.
On Monday another cold front is expected to move into the northern peninsula during the day as the aforementioned deepening storm system moves up the eastern seaboard. Similar to yesterday models show this front stalling out across the north-central Florida peninsula through mid week as the front becomes parallel to the upper level southwesterly flow. The stalling front combined with moisture pooling along it and some upper level energy moving across the area will support some unsettled weather with chances for showers and isolated storms with the possibility of some beneficial rainfall especially from the I-4 corridor north into the Nature coast where the highest rain chances (probability of precipitation 40-60%) will reside closest to the stalled frontal boundary. In addition to the rain chances a few strong to severe storms may be possible across the northern Nature coast on Monday as well so stay tuned to later forecasts. Temperatures will remain well above normal with overnight lows generally in the upper 60s to lower 70s, with daytime highs in the lower to mid 80s along the coast, and upper 80s to lower 90s inland.
High pressure across the southern peninsula this afternoon will move south of the waters tonight as a cold front moves into and south through the waters on Friday bringing with it chances for showers and isolated storms. West winds ahead of the front tonight will shift to the northwest and north during Friday and Friday night in the wake of the front, with winds becoming northeast to east on Saturday as high pressure to the north shifts eastward into the Atlantic. Winds will become southeast to south with speeds increasing into the Cautionary or Small Craft range on Sunday and Monday with some rough boating conditions developing as the gradient tightens ahead of a stronger cold front which will be approaching on Monday with increasing chances for showers and storms as the front moves into and then stalls out across the waters through mid week.
Humidity values will remain above critical levels through Thursday. Some drier air will move into the region on Saturday in the wake of a cold front, but Red Flag conditions are not expected. Increasing moisture is expected on Sunday and into early next week as a breezy to windy southerly wind flow develops over the region ahead of the next cold front. This next cold front will move into the region on Monday, then will likely stall out across the area through Wednesday with increased chances for shower and storms. Increasing 20 foot winds and transport winds ahead of the front will support high dispersions across the forecast area on Sunday and Monday, otherwise no other fire weather hazards are expected at this time.
