...New

Issued at 926am EST Tuesday Nov 29 2022

There are no chances to today's forecast. Dry weather will dominate with winds becoming breezy out of the east. A brief stray shower cannot be totally ruled out across the area, but besides that expect dry and warm conditions to prevail.

.SHORT TERM... Issued at 350am EST Tuesday Nov 29 2022

An upper (H500) ridge will retrograde westward, with the center being positioned over Cuba. A low-level ridge will become centered well offshore of the Carolinas. This will allow for low amplitude, quasi-zonal flow to become established aloft, while the southeast periphery of a surface ridge is draped over South Florida. As a result, easterly flow will become established. A modest pressure/geopotential height gradient should develop within boundary layer, allowing for breezy conditions along the east coast at times. Overall, mostly dry and benign weather should continue through Tuesday, although cannot rule out a few showers along the east coast. By Wednesday, winds will subtlety veer from east to east/southeast. This will allow for advection of a maritime tropical airmass characterized by higher theta-e value. This gradual moisture return and modest low-level convergence will allow for an uptick in shower activity, as isolated to scattered showers will be possible through Wednesday. The heightened instability may allow for an isolated thunderstorm or two, however thunderstorm development is generally unlikely. Aside from locally gusty winds and reduced visibility within showers, land- based impacts will be limited through Wednesday. Seasonably warm temperatures will continue across South Florida. Maximum temperatures in the low/mid 80s can be expected today. Wednesday may feature temperatures warmer by a degree or two owing to the subtle southerly shift of the wind field. Overnight, mild temperatures ranging from the mid 60s/lower 70s can be expected for interior/coasts respectively.

Long Term
Issued at 350am EST Tuesday Nov 29 2022

By the middle of the week, a mid-level short-wave trough will propagate across the Great Lakes, with an attendant frontal boundary traversing towards the Mid-Atlantic states and eventually the northeast. Latest guidance indicates that a distinct cold frontal passage imparting on South Florida is unlikely at this time, as the sharpest temperatures gradients appear to extend into the central Florida region (further north from the CFWA). Low- level convergence within the SFC-925 hPa wind field may allow for the development of some semi-organized shower development – not too atypical ahead of frontal systems – however any associated impacts would be limited as forcing weakens significantly over South Florida. As this frontal system eventually passes eastward, an upper ridge will emerge over the Gulf of Mexico towards the end of this week. Modest SFC-850 hPa pressure/geopotential height gradient will allow for a fresh northeasterly breeze to develop, ushering in a cooler maritime airmass. The frictional convergence near the east coast may result in isolated/scattered shower activity through the weekend. Again, nothing too concerning here as far as land-based impacts go. Maximum temperatures will be seasonably warm Thursday, and then gradually decreasing to seasonable temperatures towards the end of the week and through the weekend. Afternoon highs reaching the low/mid 80s and mild overnight temperatures in the upper 60s/lower 70s for the interior/coasts. After Thursday, maximum temperatures may struggle to exceed 80 degrees for some locations.

Marine
Issued at 350am EST Tuesday Nov 29 2022

Relatively benign conditions prevail, although seas may be choppy at times for the Atlantic waters as moderate easterly flow becomes established. Winds will gradually shift out of the east/southeast ahead of an approaching frontal system, then veer out of the northeast by Friday and through much of the weekend. Seas generally will not exceed 2-4 ft in height for the Atlantic waters, and 1-2 feet for the Gulf waters. Conditions are expected to deteriorate by Wednesday afternoon ahead of an approaching frontal system, and may be hazardous at times.

Beaches
Issued at 350am EST Tuesday Nov 29 2022

The return of onshore flow will result in a high risk for rip currents for coastal Palm Beach County, while a moderate risk for rip currents will be present for the remainder of the east coast. This threat may continue through the week, as flow remains onshore for extended periods.

NOAA Miami FL Office: Watches - Warnings - Advisories
FL...High Rip Current Risk until 7pm EST this evening for FLZ168.

AM...None. GM...None.
