Area Forecast Discussion . UPDATED National Weather Service Miami FL 728 AM EDT Fri Aug 7 2020

. 12z Aviation Update .

Aviation. VFR conditions expected through the period again today. Convection will develop later this morning, 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.

Prev Discussion. /issued 408 AM EDT Fri Aug 7 2020/

Discussion .

Short Term (Tonight through Saturday Night):

Models continue to depict a persistent pattern for the short term. A quasi-zonal flow aloft will be in place on Sunday with mid level high pressure and sfc ridging over the northern half of the Florida peninsula. This synoptic scenario will help in bringing POPs and WX coverage down a little from previous forecasts, but still expecting active periods of showers and storms in the afternoon hours. With the ridge just north of SoFlo, modest easterly flow will persist during daytime hours, and becoming light and variable at times during the night hours.

In terms of moisture availability, MFL sounding and model data still keep PWATS in the 1.6-1.8/in range, which confirms that there is still good moisture for deep convection to materialize. However, in terms of lifting mechanisms, the main player will again be afternoon sea breezes, with interior areas having the best chances as sea breeze boundaries push inland. The Atlantic metro areas should also experience a few strong storms each afternoon, with periods of localized flooding rains and gusty winds. Models do hint at a few small perturbations moving aloft that may disrupt the zonal flow at times and may add an extra push to any developing strong updraft during the next couple of days.

Temperatures remain in the high 80s near the coast, and up to the mid 90s inland and west coast. Nighttime periods will become humid and muggy at times as winds relax.

Long Term (Sunday through Friday Morning):

Western Atlantic subtropical high pressure will facilitate easterly to southeasterly low/mid-level flow across South Florida throughout the extended forecast period (a typical flow pattern for this time of year). The high pressure and associated weak pressure gradient will maintain rather light tropospheric flow, generally becoming dominated by sea breeze circulations each afternoon. Anticipate the development of scattered to numerous showers and thunderstorms along an inland advancing Atlantic sea breeze each afternoon, generally spreading westward towards the Gulf Coast and Lake Okeechobee region.

While boundary-layer moisture should remain adequate for the development of cumulus convection each afternoon (mainly focused across the interior and Gulf Coast of South Florida), medium-range model guidance continues to depict relatively dry air advecting towards the region from the western Atlantic and southeastern Caribbean Sea by mid-week. If this low/mid-level dry air does materialize across the area, precipitation chances could drop below average amid weak synoptic forcing and a lack of convective instability. Will continue to monitor model trends for the potential of reducing precipitation chances in the extended period, though leaning towards climatology and the National Blend of Models (NBM) for now. Maximum temperatures will remain near normal for this time of year, with upper 80s to lower 90s anticipated across the eastern portions of South Florida, and lower to middle 90s across the inland and western areas.

Marine .

High pressure over the west Atlantic will keep moderate easterly flow through the forecast period with generally benign boating conditions prevailing. Only exception will be in the vicinity of any thunderstorms, which will bring brief periods of rough seas and gusty winds.
