Area Forecast Discussion...UPDATED
National Weather Service Miami FL
147 PM EDT Mon Apr 4 2022

.AVIATION(18Z TAFS)...

Showers and storms continue to develop along stalled frontal
boundary. Sea breezes and outflow boundaries will allow for
additional development. VCTS this afternoon for all terminals.
Periods of MVFR or even IFR are possible in and around showers and
thunderstorms and will be handled with amendments and TEMPOs. At
KAPF, winds will shift around to the southwest in the afternoon as a
Gulf breeze develops. Light winds overnight. Breezy at times gusty
southerly winds tomorrow, with lower overall convective coverage.

&&

.PREV DISCUSSION... (Issued 916 AM EDT Mon Apr 4 2022)

UPDATE...
A few showers and storms along the east coast or just offshore so
far this morning. Bulk of activity has been near Palm Beach County
and to the south over the upper keys. Hi-res model guidance
continues to be very variable this morning with how much
development occurs over the east coast before the seabreeze
develops this afternoon, as well as location of just onshore or
offshore. However, the potential for streaming showers to effect
a localized area remain possible. With high rainfall rates, these
streamers could produce locally heavy rainfall that may lead to
flooding. Therefore, the Weather Prediction center continues to
have a Marginal risk of excessive rainfall for the east coast.

A frontal boundary remains across the region with an unsettled
weather pattern once again this afternoon. The 12Z MFL sounding
shows that the atmosphere is conducive for the potential of strong
to severe storms this afternoon. Mid-level lapse rates around
6.5-7C/km, 500mb temps around -12C along with 20-30 knots of bulk
shear will allow for upward growth of storms. Scattered showers
and storms will form along the frontal boundary and the sea
breezes this afternoon. Given the favorable parameters, the Storm
Prediction Center has placed most of South Florida in a marginal
risk for severe weather. Main hazards will be strong to damaging
winds, hail up to 1 inch, and heavy downpours. Can not rule out an
isolated tornado along boundary or sea breeze interactions.

A few adjustments in the forecast to account for latest radar
trends and current observations.

PREV DISCUSSION... (Issued 741 AM EDT Mon Apr 4 2022)

AVIATION(12Z TAFS)...
Mainly VFR conditions to start the taf period. Winds will
increase out of the east southeast by mid-morning. Hi-res models
are having trouble depicting location of convection this morning
and afternoon. For now carrying VCSH then VCTS later this morning
and afternoon. Periods of MVFR or even IFR are possible in and
around showers and thunderstorms and will be handled with
amendments and TEMPOs. At KAPF, winds will shift around to the
southwest in the afternoon as a Gulf breeze develops. Light winds
overnight.

PREV DISCUSSION... (Issued 317 AM EDT Mon Apr 4 2022)

SHORT TERM (Today through Tuesday)...

Latest sfc analyses and model data keep a semi-stationary,
decaying front just off the southern tip of the Florida peninsula
and into the Florida Keys today. Meanwhile, model consensus
depicts high pressure building over the SE CONUS, Which will
influence our synoptic flow and veer it more to the SE today.

With this synoptic scenario in place, expect still abundant
moisture to linger over SoFlo, and combine with daytime
heating/sea breeze boundaries for another round of scattered to
numerous showers and thunderstorms. Better chances for the east
coast metro areas will be in the morning, then shifting over the
interior and west coast areas in the afternoon. Latest model
sounding data still depict 500 mb temps in the -11 to -12 degrees
celsius, which will support vertical development of a few strong
cells, especially this afternoon. SPC latest outlook places most
of the area again in the marginal level for risk of severe
weather. Main hazards will be gusty winds, hail, and heavy
downpours.

Models also show the remnants of the front finally moving away
from the area late Tuesday, as a trough pushes across the SE
CONUS. This will briefly lower POPs across SoFlo with coverage
mainly isolated. It will also enhance the southerly flow across
the area, with breezy periods expected in the afternoon.

Warm temps continue each day with daytime highs in the low-mid
80s near the coast, and in the upper 70s inland.

LONG TERM (Wednesday through Sunday)...

Models show prevailing zonal flow aloft on Wednesday, while
enough remnant moisture lingers across SoFlo. This should be
enough for a few afternoon showers to develop. Meanwhile, a mid
level trough is shown on latest long range solutions moving
eastward across the E CONUS, with an associated sfc front pushing
into the east GOMEX and the west coast of Florida. The convection
ahead of this front will bring another round of increasing
showers/t-storms on Thursday. Models show fair agreement in
pushing this front across the state, with a cooling trend in its
wake beginning Friday night and through the weekend. The situation
will continue to be closely monitored, and the forecast will
continue to be adjusted accordingly.

MARINE...

Winds will gradually shift to a more easterly flow today and
increase into the 10 to 15 kt range as the remnants of a front
dissipate over the southern waters. Potential for thunderstorms
remain in place during the next couple of days, with Brief periods
of rough seas and gusty winds will accompany any storm that
forms. High pressure shifting well east of Florida turn winds to
the southwest during the latter part of the week ahead of another
cold front moving into Florida. Seas will be generally 3 feet or
less outside of showers and thunderstorms, building slightly
Thursday as SW winds increase some.

BEACHES...

The threat of rip currents will increase to moderate today for all
the Atlantic beaches as easterly flow re-establishes. But it
should be short-lived as the threat decreases for the east coast
metro areas as the winds become more southerly for the middle to
end of this week.
