.SHORT TERM... (Rest of today through Tuesday) Issued at 130pm EST Monday Nov 28 2022

A departing low pressure system over the northeastern United States will continue to propagate northeastward today, with an associated surface frontal boundary in tow. The frontal boundary extends into our area, weak in nature, due to a lack of baroclinic forcing (and a moderation of the airmass behind the boundary). A few measly isolated showers may be able to briefly develop along the frontal boundary as local ascent is maximized but overall the passage of the front will be a fairly dry one. One important change will be the gradually veering of winds to a northeasterly direction behind the passage of the boundary, which will result in onshore flow along the east coast. This will result in high temperatures remaining in the low to mid 80s along the immediate east coast, with the upper 80s remaining confined to the southern Everglades.

Although cold air advection (CAA) will be limited in nature behind the frontal passage, light northeasterly winds will allow for temperatures across inland areas to cool overnight with temperatures in the low 60s forecast across the Lake Okeechobee region. Elsewhere, temperatures in the upper 60s to low 70s are possible along both coasts. While the model guidance and the HREF does not explicitly show widespread areas of fog tomorrow morning, it would not be surprising to see a few localized patches of fog across southern inland portions of our area.

With the establishment of a surface ridge of high pressure over the southwestern Atlantic on Tuesday, a pressure gradient will develop and become enhanced in nature. This will result in breezy to gusty conditions on Tuesday with a fresh easterly component. Given the onshore flow, a few stray isolated showers could be possible along the east coast during the afternoon hours. High temperatures will reach the low 80s along the east coast and Lake Okeechobee region with temperatures in the mid 80s along the Gulf coast and western Everglades.

Long Term
(Tuesday night through next Sunday) Issued at 130pm EST Monday Nov 28 2022

By the middle of the week, a strong mid-level trough will be propagating across the Great Lakes, with an attendant frontal boundary stretching down into the Southeast US. It is too early to speculate if this front will make it all the way to South Florida and result in a noticeable reduction in temperatures, however, the pre-frontal regime will likely bring increased atmospheric moisture and chances for showers. As this feature eventually passes eastward, an upper ridge becomes re-enforced over the northern Gulf of Mexico towards the end of this week, ushering in drier air and normal temperatures. Overall, the late week/weekend period will feature east/northeasterly winds and a dry and mostly benign weather regime. Maximum temperatures should remain near seasonable to seasonably warm, with afternoon highs reaching the low/mid 80s and mild overnight temperatures in the upper 60s/lower 70s for the interior/coasts.

Marine
Issued at 130pm EST Monday Nov 28 2022

Mostly benign conditions will prevail across the local waters today outside of a few isolated showers. A weak frontal boundary continues to move through the region, which will result in north to northeasterly winds by late today. By tomorrow, a developing pressure gradient will allow for breezy to gusty winds over area waters which will result in seas of 3-4 feet over the Atlantic waters with lower seas 2-3 feet over the nearshore Gulf waters.

Beaches
Issued at 130pm EST Monday Nov 28 2022

A moderate risk for rip currents will be present for all east coast beaches today. As onshore winds enhance tomorrow, an elevated rip current risk will materialize and persist for much of the upcoming week.
