.SHORT TERM...
(Today through Tuesday)
Issued at 218 AM EDT Mon Mar 16 2026

Surface analysis early this morning shows a stout low-level cyclone
traversing across the Great Lakes area while dragging a strong cold
front across the Plains. This complex will continue to progress
eastward today, with the front forecast to slide south along the
peninsula and reach our area later tonight. Isolated shower and
thunderstorm activity will be possible ahead of the front today,
especially across portions of the East Coast metro where
instability, shear and forcing will be maximized. Some of these
storms could be strong to severe in nature; there`s a Marginal Risk
(Level 1 of 5) of damaging winds (> 60 mph) and quarter-sized hail
for portions of the East Coast metro this afternoon. Isolated street
flooding could also be possible.

There remains some uncertainty regarding the frontal approach later
tonight, with models ping-ponging on its health and the potential
for convective development as it moves across the area. For now,
went with the solution that maintains some level of frontogenesis
and brings the line of showers and storms across the region
between 8PM-2AM. Some of those storms could bring heavy rain and
gusty winds, but chances for severe impacts associated with the
line look pretty meager at this time, and given the speed of the
line, hydro concerns also remain limited.

The front is forecast to clear the area by early Tuesday morning.
Northerly flow behind the front will bring a cooler airmass across
the region. Moisture along the column will remain somewhat elevated,
which could result in sparse showers and a few thunderstorms over
the local waters and the immediate southeastern coast throughout
the day.

Abnormally warm temperatures in the mid to upper 80s will
continue today as southerly flow continues to advect warmer, moist
air over the region. Temperatures will struggle to rise above the
60s on Tuesday once the front clears the area and the cooler air
mass moves over the region.

.LONG TERM...
(Tuesday night through Sunday)
Issued at 218 AM EDT Mon Mar 16 2026

Northerly flow will prevail across the area, promoting cooler
conditions through the end of the week.  Overnight temperatures
Tuesday and Wednesday nights will drop to the upper 40s and lower
50s across the interior, and low 60s along the East Coast. Daytime
temperatures for the rest of the week will remain in the
comfortable 70s, gradually rising to the 80s over the weekend.

Model guidance shows the aforementioned front lingering over the FL
straits and western Caribbean waters on Wednesday. Its presence
near our area will help maintain moisture in place along the
atmospheric column, keeping chances for showers and a few
thunderstorms in the 30-40% range for portions of the East Coast
metro on Wednesday and Thursday. The front is forecast to
dissipate come Friday, and surface high will build over the
region, ushering dry, sunny conditions in time for the weekend.

.AVIATION...
(06Z TAFS)
Issued at 218 AM EDT Mon Mar 16 2026

SHRA/TSRA will be possible throughout the day today as a cold
front approaches, and could result in brief periods of sub-VFR
conditions across East Coast terminals, especially between 18-22Z,
and then again between 00-06Z. Southerly winds will prevail today,
but will gradually veer out of the west, then the northwest
overnight as the front moves through.

&&

.MARINE...
Issued at 218 AM EDT Mon Mar 16 2026

A moderate to breezy southeasterly breeze will prevail across all
local waters today ahead of a frontal approach late tonight.  Seas
will remain below 3 feet across the Gulf waters, and between 3-5
feet across the Atlantic waters. Scattered to numerous showers will
be possible across all local waters today, with potentially rough
seas and strong winds near any storms. Winds will increase out of
the north behind the front on Tuesday, resulting in hazardous
conditions through the end of the week.

.BEACHES...
Issued at 218 AM EDT Mon Mar 16 2026

Palm Beach and Broward county beaches will be at high risk of rip
currents today as northerly swell persists.
