Area Forecast Discussion National Weather Service Miami FL 730 PM EDT Thu Jul 29 2021

AVIATION(00Z TAFS).

SHRA/TSRA possible around the eastern terminals this evening before conditions improve to dry/VFR after ~02z. Mostly dry through tomorrow morning with returning SHRA/TSRA chances after ~16-17z. Best storm chances are inland from the terminals, but can't rule out on-station impacts depending upon trends. Confidence is currently too low for TAF mention however. Light winds overnight become SE ~08-10kt tomorrow afternoon at the eastern TAF sites.

PREV DISCUSSION. (Issued 228 PM EDT Thu Jul 29 2021)

SHORT TERM (This Afternoon through Friday) . For the remainder of this afternoon, numerous showers and scattered thunderstorms are expected to cover most of the interior of the peninsula up to the Lake Okeechobee area, resulting from the interaction of the seabreezes and earlier convection over the metro areas of both coasts. Mean storm motion this afternoon is towards the N-NE, which may cause a few storms to build back towards the east coast metro suburbs towards early evening. Gulf coast areas should remain mostly dry for the remainder of the afternoon.

Localized rain amounts in excess of 2" have been observed each of the past few days, and expect this to happen again this afternoon. The main focus for the heaviest rainfall and localized flooding will be over the interior and Lake Okeechobee areas, with some potential for back-building into the western metro sections of the east coast.

Tonight and Friday . high pressure in the mid/upper levels will build into South Florida from the Bahamas in the wake of the upper low over western Cuba moving into the southern Gulf of Mexico. Water vapor imagery is showing a decent swath of drier air over the western Bahamas likely associated with convergence aloft and perhaps a little bit of Saharan dust, and this feature is forecast to move over the area late tonight and Friday. Model consensus is responding to this feature by showing slightly lower PoPs compared to the past few days, and will follow this general solution. Nevertheless, scattered to locally numerous showers and thunderstorms will still be the case on Friday, focusing more over the interior and Lake Okeechobee/Palm Beach County areas during the afternoon and early evening as the mean storm motion will be towards the NW.

Heat index values will top out at 100-105F over most areas this afternoon and Friday outside of areas of precipitation, with the duration of the higher values increasing on Friday with longer periods of sunshine.

LONG TERM .

Friday Night through Sunday:

Mid-level ridging will prevail along the equatorward side of an upper trough located over New England. The ridge will strengthen across our area this weekend as mid-level heights rise to 594-595 dm. This will support the westward branching of surface high pressure into our area from the central Atlantic during this time. With deep ridging and subsidence in control look for temperatures to really heat up this weekend. Leaning towards the National Blend of Models (NBM) 90th percentile values for high temperatures, which suggests mid to upper 90s for inland areas with lower 90s along the coasts. Given the onshore wind regime along the Atlantic, a decent temperature gradient should exist between the beaches (upper 80s) and western suburbs closest to the Everglades (upper 90s). Be sure to stay hydrated and take breaks if you have outdoor plans. Otherwise despite the prevalent ridging still expect a few showers and storms with the flow regime favoring western inland area and the Gulf coast for the best chances.

Monday through Thursday:

Mean upper troughing will deepen across the eastern states while suppressing the mid-level ridge farther equatorward towards the Greater Antilles and Bahamas. While our area remains within the western periphery of the surface ridge, this pattern change should allow more moisture to flow back into the region. As such shower and storm coverage should increase. Given light steering flow locally heavy rainfall and street flooding are the primary concerns, along with a few stronger storms producing gusty winds. Otherwise temperatures should remain seasonally warm, with highs mostly in the 90s and lows in the mid 70s to around 80.

AVIATION(18Z TAFS) .

Scattered SHRA/TSRA affecting some east coast terminals, but not expected to be widespread as the precipitation gradually moves inland. TEMPO TSRA with MVFR conditions being handled in the forecasts on a short term basis, with VCTS the prevailing conditions through 00z (earlier ending at KAPF). Slightly drier for Friday with slightly less TSRA coverage and SE wind 8-10 knots by the end of the forecast period.

MARINE .

High pressure at the surface will build across South Florida from the Atlantic to end the week and through the upcoming weekend. This will lead to prevailing SE-S winds across the local waters. Speeds will be generally 10 knots or less with seas 3 ft or less. Showers and thunderstorms will be fairly low in coverage compared to the past few days, then perhaps increasing again on Monday.
