.SHORT TERM... (Rest of today through Tuesday) Issued at 1218pm EDT Monday Mar 18 2024

Southern Florida remains in the warm sector ahead of a weak frontal boundary, with prevailing southwest winds and increasing warm moisture advection. The front itself will be rapidly decaying as it becomes further detached from its parent trough/low complex well to the NE. Thus, little impacts are expected from this feature over South Florida this afternoon, with some isolated to scattered showers or thunderstorms possible, mainly around the Lake region.

The overall synoptic scenario may allow for an efficient daytime heating process, which could result in some of the hottest temperatures of the year. Highs could push into the low 90s in some areas.

Model consensus show the front finally moving across and out of the peninsula by early Tuesday. Winds veer to the NW and then NE by Tuesday afternoon in the wake of the FROPA, with subsidence and stable air filtering into the area. Along with building high pressure, the forecast calls for benign weather conditions to establish on Tuesday with afternoon temperatures cooling down into the 70s

Long Term
(Tuesday night through next Sunday) Issued at 230pm EDT Monday Mar 18 2024

Beautiful weather is expected Wednesday and Thursday as high pressure to our north remains in control. Temperatures during this time period will be at or slightly below normal.

A potent system is expected to cross FL Friday into early Saturday. Deterministic and ensemble guidance all points to the potential for heavy rainfall across portions of South FL. Early forecast Quantitative Precipitation Forecast ranges from 1-3 inches, although some locally higher amounts will certainly be possible. Still too early to determine if there will be a severe threat on Friday into Friday evening, but that potential will be monitored closely over the next several days. Southerly winds will be quite gusty through late Friday night, especially along the coasts, with gusts of 30 mph + possible.

Once the system moves off to the east, much drier conditions are expected for Sunday into early next week as weak upper level ridging builds into the region. Temperatures Friday through the weekend will be right around climatological norms.

Marine
Issued at 1218pm EDT Monday Mar 18 2024

Winds shift to the southwest today ahead of an approaching frontal boundary. A few showers are possible this afternoon, particularly for the northern waters and Lake Okeechobee. Winds and seas are expected to increase, especially over the Atlantic waters, with hazardous marine conditions developing by tonight and lasting through Tuesday. Conditions will gradually subside by mid week.

Beaches
Issued at 1218pm EDT Monday Mar 18 2024

The risk for rip currents across the east coast beaches increase on Tuesday behind a cold front passage. The risk may remain elevated through the rest of the week as easterly flow returns.
