Area Forecast Discussion National Weather Service Miami FL 958 AM EDT Sun Jun 13 2021

UPDATE. Showers and storms that have been ongoing this morning have generally been on the downward trend. A lingering shower into Miami-Dade along an outflow boundary and some showers along the west interior.

Another afternoon of showers and thunderstorms across South Florida, mainly for the east coast today. Hi-res models this morning continue to have a hard time of pinpointing the exact location of the heaviest showers and storms. Regardless, some areas will see heavy downpours while others may stay dry today. The 12Z MFL sounding shows southwesterly winds throughout the vertical column and a little stronger than yesterday. This will keep the east coast seabreeze pinned closer to the coast. Therefore, the best chance for heavy rainfall and strong storms looks to be along the I-95 corridor and the coastal areas. This could change if the sea breeze is able to push a little further inland than expected.

Moisture from the Caribbean continues to be advected into the area with PWAT levels of 1.7 inches. Diurnal heating with temperatures into the low 90s will provide instability for storms to develop this afternoon. DCAPE values are above 1000J/kg on this mornings sounding and model soundings, which is a little higher than yesterday. Given the environmental parameters the main impacts will be heavy rainfall, leading to potential localized flooding especially for coastal areas, lightning strikes and downburst gusty wind potential.

PREV DISCUSSION. (Issued 734 AM EDT Sun Jun 13 2021)

AVIATION(12Z TAFS) . Southwesterly winds across the area with mainly VFR conditions outside of afternoon convection. Afternoon showers and thunderstorms focusing along the east coast sea breeze, VCTS included with TEMPOS likely to be added with future amendments once location and timing confidence increase. Light SW winds overnight with showers and storms a little earlier tomorrow in the late morning hours.

PREV DISCUSSION . (Issued 253 AM EDT Sun Jun 13 2021)

SHORT TERM (Now through Monday) .

A very weak boundary across the Atlantic has developed generally from extreme south Miami-Dade through roughly Grand Bahama. A few showers and even a thunderstorm or two has developed through the early morning hours near the boundary. This should fizzle through the morning and into the afternoon hours, though an isolated shower or thunderstorm will remain possible areawide as the column remains quite moist (13/00z RAOB showed around 2" pwat) so any lift may be just enough to generate something.

The better lift or "generator of convection" comes later this morning and this afternoon as both a Gulf breeze and Atlantic sea breeze develop along their respective coastlines. With weak somewhat unidirectional flow from 0-6km, expect the gulf breeze to surge inland at a decent clip limiting the Naples metro's rain chances just a bit. However, the southwest flow does signal a better chances across the interior and Atlantic metro(s) today. Forecast soundings across the Atlantic continue to indicate around ~2" pwats with a very weak deep layer flow, meaning slow storm motion will be a concern along the Atlantic (and perhaps localized flooding). Further, H5 temperatures are still rather cool (between 7-9 degrees C) as a mid level trough remains over much of the state. Forecast instability values range from modest to moderate and DCAPE values are in some cases approaching 850-1000 J/KG. There certainly could be a few strong damaging wind gusts as the stronger, more robust updrafts collapse.

Monday looks to be the rainiest day between the two. A tropical airmass will begin to advect into the region from the western Caribbean along with plenty of lift from a mid/upper level vort/shear axis settling southward over much of the state in unison with the upper trough remaining locked across the state. With such a higher concentration of moisture and continued lackluster storm motion, more localized flooding Monday can be expected for both metro areas. The good news is with the increase in cloud cover and rain chances, temperatures will be a bit lower on Monday than today as much of the region today should approach (if not exceed) the 90 degree mark.

LONG TERM (Monday Night through Saturday) .

The unsettled weather pattern will continue into the middle portion of the week as the mid to upper level trough continues to amplify over the region. This will allow for the south to southwesterly wind flow to continue to bring plenty of deep layer tropical moisture into the region. The PWAT values through the middle of the week are forecasted to remain between 1.8 and 2 inches. This will allow for scattered to numerous showers and thunderstorms to develop along the east and west coast sea breezes as they move inland. With the south southwesterly flow in place, the greatest chances of showers and thunderstorms will be over the interior and east coast metro areas during the afternoon and evening hours, and then over the Gulf and Atlantic waters during the overnight and early morning hours. With the mid level trough in place, the cooler temperatures aloft will also remain as forecasted 500 mb temperatures remain between -7 and -9C. This combined with rather modest lapse rates will provide the opportunity for some of the storms to become strong containing gusty winds and heavy downpours.

By the end of the week, the amount of uncertainty in the forecast remains on the high side. The National Hurricane Center is currently watching an area of disturbed weather over the Bay of Campeche. This area of disturbed weather looks to slowly move over the Gulf of Mexico well to the west of the region as a mid level ridge of high pressure builds back into the Bahamas and then over the Florida Straits by the end of the week. At the same time, a Saharan Dust Layer (SAL) is forecasted to move into the region by the end of the week. This SAL could help in drying things out over the mid levels which would help to reduce shower and thunderstorms coverage. The uncertainty comes into play as to how far north this SAL layer moves in as well as how far to the west the area of disturbed weather in the Gulf moves as the latest model guidance remains in disagreement in these features. The forecast for the end of the week currently represents a blend of models with a chance of showers and thunderstorms each afternoon and evening as the sea breezes develops. This will continue to be monitored as the week progresses.

MARINE .

A generally benign southwesterly flow is expected across the coastal waters of south Florida through the period. Can't rule out intermittent cautionary headlines from time to time as pressure gradient may tighten with lower pressures in the southwest Gulf of Mexico and higher pressure over the western Atlantic. Outside of this, the only other concern would be daily convection chances, which may have impacts such as cloud-to-water lightning, heavy rainfall, gusty winds, and locally rougher seas near or around convection.
