Area Forecast Discussion National Weather Service Miami FL 1010 AM EDT Tue Sep 21 2021

UPDATE. Coastal convergence this morning has allowed plenty of showers and a few isolated storms along the east coast. Most of the activity has been in Broward and Palm Beach Counties, so far. The 12z MFL sounding had a precipitable water value right around 2.2 inches so there is plenty of moisture in the atmosphere. This is leading to heavy rainfall with efficient rainfall rates, which has lead to minor flooding of low- lying areas especially areas in Palm Beach that saw heavy rainfall last night. Storms have been moving a little more this morning with a mean easterly wind around 8 knots or so, but there have been multiple rounds particularly in Palm Beach.

The rest of the morning more showers and storms will continue to develop over the Atlantic waters and east coast. Miami-Dade should also begin to get in on the action as well with showers already beginning to develop in the southern Atlantic waters. Localized flooding due to heavy rain and multiple rounds of showers and storms will continue to be the primary concern. Hi-res models continue to depict activity shifting towards the interior and west coast this afternoon and evening. Over the western half of the region a little better diurnal heating with less cloud cover and lapse rates have improved some where a stronger storm may be able to produce a strong wind gust over western areas. However, the main impact will continue to be the heavy rainfall with a localized flooding concern. A few changes to POPs given the latest trends and current radar but overall impacts remain the same.

PREV DISCUSSION. (Issued 727 AM EDT Tue Sep 21 2021)

AVIATION(12Z TAFS) . Showers over the Atlantic waters continue to move over the east coast this morning. VCSH with TEMPOS for SHRA where coverage is highest this morning. Scattered showers and storms possible late morning into afternoon before storms shift inland from the terminals by late afternoon to early evening. Light/variable winds this morning will become easterly around 10 kt, except at KAPF where the Gulf Breeze should result in westerly winds around 19-20z. L/V winds overnight.

PREV DISCUSSION . (Issued 310 AM EDT Tue Sep 21 2021)

SHORT TERM (Tuesday through Wednesday) .

The periphery of a weak Bermuda High remains in place over South Florida as a middle to upper level trough continues to advect eastward over the Midwestern United States. Between these two synoptic features, a plume of deep tropical moisture continues to remain in place over South Florida allowing for an unsettled and soggy pattern to continue for our area. The lack of a pressure gradient and a relatively weak ridge at the surface will allow for weak easterly flow to prevail during the day, which will favor shower and thunderstorm activity along sea-breeze and propagating outflow boundaries. With an easterly flow pattern, albeit weak, the greatest coverage of showers and thunderstorms will shift from the east coast during the morning and early afternoon hours to the interior and Gulf coast during the mid afternoon to early evening hours. With abundant moisture present in the vertical column and stagnant flow aloft, the concern for localized flooding across South Florida continues today, especially in areas that have received previous rounds of heavy rainfall over the last several days. With the onset of sunset, winds will become light and variable with the potential of a few showers and thunderstorms lingering into the early evening hours before the greatest coverage of shower and thunderstorm activity shifts to the offshore waters overnight.

Wet and unsettled remains in the forecast for Wednesday as South Florida remains in a moist tropical airmass out ahead of a frontal boundary moving southeastwards across the southern United States. Flow out ahead of the aforementioned frontal boundary will be out of the southwest over our area which will act to focus the greatest coverage of showers and thunderstorms across the interior and east coast metro areas on Wednesday. A similar evolution to Tuesday, as storm organization will be multi-cellular in nature with new development occurring along propagating outflow boundaries and sea- breeze collisions. With precipitable water values upwards of 2.0 inches, slow storm motion, and relatively stagnant flow at the surface, localized flooding concerns remain with us for Wednesday.

LONG TERM (Wednesday Night through Monday) .

Typical late summer weather to start the long term period. Generally, a light low level flow is expected, which will lead to the development of sea breezes daily during the afternoon hours. These mesoscale boundaries in conjunction with a tropical air mass across the region will generate continued daily convection. There will be a break overnight for much of the interior, however, nocturnal convection will likely develop over the Gulf Stream and perhaps propagate into portions of the Atlantic metros.

Going into late week all eyes begin to shift upstream across portions of the Southeast U.S. as our first autumn cold front will begin moving southward through the state by Thursday. The bad news is it appears that most of the globals are wanting to at least briefly stall the front around the I-4 corridor or just north of the Lake Okeechobee region through the last part of the workweek and into the weekend. This surface front will be the focus for continued rain/storm chances, especially across our north around the Lake Okeechobee region. Will lean more toward this final solution for the front given 1) climo and 2) globals showing lack of upper trough amplification, which will limit exactly how far the front progresses. That said, the GEM has been showing a bit more upper level energy to give the final push that could clear the region early next week. At this point this would be the outlier, but not impossible despite the limiting factors noted above. That said, expect continued late summer warm/muggy/and perhaps wet at times pattern.

MARINE .

Weak high pressure remains established over the area leading to light flow and benign marine conditions outside of shower and thunderstorm activity. Shower and thunderstorms remain possible over South Florida waters through late week. Locally higher winds and seas are possible in and around showers and thunderstorms.
