...New Long Term

.SHORT TERM... (This afternoon through Saturday) Issued at 1158am EST Fri Dec 8 2023

Predominantly dry conditions are expected through the short term period as a dry air mass remains over the area. Surface high pressure remains the primary synoptic feature, which will keep surface flow east to southeasterly through the remainder of today and through Saturday. As the boundary layer moistens with easterly surface flow in place, a few isolated showers will be possible for east coast metro areas this afternoon through tomorrow. Highs will be in the mid to upper 70s today. Lows tonight will be in the lower 60s for interior areas, and mid to upper 60s for coastal regions. On Saturday, the aforementioned area of high pressure continues its eastward trek, as a mid-level trough begins to dig across the Great Plains. This influence should keep predominantly dry weather across the CWA, with a continuing chance for isolated showers across eastern areas. Highs on Saturday will be a little bit warmer, with lower 80s expected for eastern areas and mid 80s for western areas.

Long Term
(Saturday night through next Thursday) Issued at 231pm EST Fri Dec 8 2023

On Sunday, the intensifying mid-level trough is anticipated to advance further into the Southeast and Gulf of Mexico. Concurrently, a robust surface frontal boundary will progress through the Southeast, extending into Northern and Central Florida as the day unfolds. Ahead of this frontal system, regional winds are expected to shift towards a south-southwesterly direction, and concurrently, the likelihood of showers and thunderstorms will incrementally heighten. However, substantial uncertainty persists regarding the specifics, as recent ensemble model outputs have indicated a deceleration in the eastward movement of both the mid- level trough and the surface frontal boundary. This delay suggests that the peak probabilities for showers and thunderstorms might occur later in the afternoon and into the evening hours. While the most favorable dynamics and instability are projected to remain significantly north, there remains a potential for a few intense thunderstorms, characterized by gusty winds and heavy downpours. Elevated values of bulk shear and mixed-layer Convective Available Potential Energy (ML CAPE) will create a conducive environment for the development of thunderstorms, contingent upon adequate low-level mass convergence. This aspect of the forecast will continue to be closely monitored throughout the week. Sundays high temperatures are expected to reach the lower 80s in east coast metropolitan areas and the mid-80s in the interior regions of Southwest Florida.

With model guidance indicating a slower movement of the frontal boundary, its passage over South Florida is now forecast for the overnight and early morning hours of Monday, possibly stalling over the Florida Straits thereafter. Cold air advection across South Florida is expected to be modest, as winds rapidly shift to a more north-northeasterly direction from Monday into Tuesday, with high pressure building from the north. Forecast uncertainty for the early to middle part of next week remains heightened due to discrepancies in model guidance regarding the strength of the incoming high pressure. A more robust high-pressure system could extend further south, potentially ushering in drier air during this period. Conversely, a weaker high-pressure system might allow the stalled frontal boundary to remain closer to the region, maintaining higher moisture levels and continued chances of showers. The latest forecast adopts a model blend, incrementally increasing shower probabilities on Tuesday and Wednesday. Mondays high temperatures are forecast to range from the upper 60s west of Lake Okeechobee to the lower 70s along the east coast. With the development of northeasterly winds, a gradual warming trend is anticipated for Tuesday and Wednesday.

Marine
Issued at 1150am EST Fri Dec 8 2023

Marine conditions today have improved, with the earlier hazardous conditions no longer present. Wave heigheights over the Atlantic waters are now more moderate, generally ranging between 3 to 5 feet. Winds are expected to continue evolving, shifting out of the east today and veering out of the southeast as the weekend approaches. The possibility of thunderstorms later in the weekend should be noted,
