Area Forecast Discussion National Weather Service Miami FL 801 AM EDT Thu Jul 16 2020

Aviation. Generally VFR with a light easterly wind pattern. Sea breezes are expected to develop with the Gulf breeze pinned to the west. Atlantic convection will spread over the east coast in the mornings and the focus will shift westward with a potential boundary collision around APF in the afternoon. Convection should diminish in the evening as the sea breezes retreat. Overnight convection should remain focused over the area waters.

Prev Discussion. /issued 329 AM EDT Thu Jul 16 2020/

Short Term (Today through Friday) . An area of high pressure will remain in control of the weather pattern across South Florida today. Easterly flow will increase as the day progresses. Scattered showers and thunderstorms this morning over the Atlantic waters as well as portions of the east coast will shift more towards the interior and west coast during the afternoon and evening hours. Shower and thunderstorm activity could become more widespread this afternoon and this evening as the sea breezes collide over the interior and west coast. The strongest storms could contain gusty winds, heavy downpours, and frequent lightning. High temperatures will still remain on the warm side as they will rise into the lower 90s across the east coast metro areas to the mid 90s across the interior sections. Triple digit heat indices will occur once again across most of South Florida late this morning into the afternoon hours.

On Friday, the latest GFS and the ECMWF show a mid level disturbance moving eastward from the Bahamas around the southern extent of the ridge of high pressure that is in place. This will help to begin to usher in deep tropical moisture into South Florida as the day progresses. The chances of showers and thunderstorms will increase across the region especially Friday afternoon and into Friday evening. Easterly flow will still remain in place, however, with the increased amount of moisture coming into the region, the potential for some flooding will exist across the urban and low lying areas due to the high rainfall rates that could occur during this time frame. High temperatures on Friday may be a couple of degrees lower then what they have been over the past several days due to increased cloud cover and increased chances of rain. Highs on Friday are forecasted to range from the upper 80s along the east coast to the lower 90s across the interior sections.

Long Term . Friday night through Wednesday night .

Active weather with a stagnant pattern .

Models are in pretty good agreement that a strong surface high will build over the central Atlantic. This will block any northward movement of any system or moisture moving west across the Atlantic, until it reaches Florida. The models are indicating that tropical moisture will continue to stream in across the region through the weekend, and at least most of next week.

The models do differ as to coverage of showers and thunderstorms over South Florida each day, with the GFS seeming to favor convection mainly over the coastal waters and the adjacent shoreline, while the ECMWF is much wetter and more widespread. Given this, PoPs have been kept at the higher end of the likely range each day, with some nocturnal lulls in activity. However, while there is a forecast lull each night, this does not mean that showers and thunderstorms are not possible. But, with the loss of diurnal heating, the atmosphere will not be as unstable as during the day.

Speaking of instability, given the amount of coverage of rain, and probable cloud cover, thunderstorms have been kept in the chance category through the period, as they may have a harder time being widespread. Much of the challenge will be getting the lift and enough instability to get them to develop. So, if the cloud cover is abundant, thunderstorms will probably be a little less likely. On the other hand, if the day starts out with sun, it could provide enough heating to enhance the instability and also allow for sea breeze development, which would then act as the lifting mechanism. So, there is a decent potential for thunderstorms each day as well, but the coverage and intensity of the storms will be very conditional through next week.

Marine . Easterly flow will continue across the Atlantic and Gulf coastal waters through the end of the week. Scattered showers and thunderstorms will be possible each day over the local waters. Chances of showers and thunderstorms will increase by the end of the week and into the upcoming weekend as a tropical wave approaches the local waters. Winds and waves could be locally higher in and around showers and thunderstorms.
