Area Forecast Discussion National Weather Service Miami FL 731 PM EDT Fri Aug 7 2020

Aviation. Mainly VFR conditions will prevail throughout the forecast period. Scattered showers and thunderstorms over the interior and west coast will diminish as the evening progresses. Winds will become light and variable during the overnight hours. Winds will increase out of the east southeast again by late Saturday morning. At KAPF, winds will shift to the southwest in the afternoon. Scattered showers and thunderstorms will develop across the interior.

Update. Updated the forecast based on current radar trends. Scattered showers and thunderstorms over the interior and west coast will continue to diminish as the evening progresses. Many areas will see dry conditions overnight as high pressure remains in control of the weather pattern across South Florida. The only exception will be across the Atlantic waters where there could be some shower activity during the overnight and early morning hours. East to southeasterly flow will continue on Saturday as high pressure remains in place. Scattered to numerous showers and thunderstorms will develop as the east and west coast sea breezes push inland. The greatest chances of showers and thunderstorms will be located across the interior and west coast sections during the afternoon and evening hours. High temperatures on Saturday will generally range from around 90 across the east coast to the mid 90s across the interior sections.

Prev Discussion. /issued 347 PM EDT Fri Aug 7 2020/

Short Term . The short term offers very few changes from the previous forecasts. High pressure at both the upper levels and the surface will likely limit much convection overall. That said, the sea/lake/gulf breeze will be enough low level convergence to generate a few showers and storms. With some drier air, gusty winds may be possible in the strongest convection. Short term guidance is showing a bit of a heavy rain signal across the Gulf region this afternoon. Some localized urban/poor drainage flooding may be possible.

Overnight, a few widely scattered showers possible over the coastal waters, but much of the region will remain dry. Going into Saturday, much of the same with the best potential for convection being across interior and the Gulf coast. Temperatures remain at or just slightly above average.

Long Term .

Saturday Night through Monday .

A subtropical ridge will extend from the western Atlantic Ocean through the western Gulf of Mexico. This will maintain light east to southeast flow through the lower troposphere. While a few ripples may pass through at times in the mid-level flow daily convection trends should be largely regulated by the sea breeze circulation pattern. This will favor morning shower/isolated thunderstorm chances on the Atlantic coast followed by greater chances/coverage over the interior and Gulf coast regions into the afternoon and early evening hours. The primary thunderstorm hazards during this time should be frequent lightning, heavy rainfall, and the possibility of an isolated strong wind gust here or there. Temperatures will be seasonal, with highs mostly in the 90s away from the coasts and lows in the 70s to around 80.

Tuesday through Friday .

The low to mid level ridge should center over the western Atlantic with a slight uptick in easterly flow anticipated locally. A somewhat drier pocket of air may advect through the region as well, potentially cutting back on late week thunderstorm coverage a bit. That said, will defer to consensus blended PoPs for the time being. Seasonal temperatures should continue.

Marine . High pressure will be in control with light to moderate easterly flow through the period. This will lead to very favorable marine conditions across the Gulf, Atlantic and Lake waters of South Florida. The only exception would be convective development where locally gusty winds, higher waves, and frequent cloud-to-water lightning will be possible.

Aviation (18z Aviation) . VFR conditions expected through the period. Convection will develop through the afternoon, generally inland; however, showers and storms may be just close enough for short fused TEMPOs for temporary wind changes. Otherwise, convection should diminish later this evening. Easterly flow is expected, which should become lighter overnight tonight.
