Synopsis.. Prevailing east southeast winds will be in place for most of the upcoming week with the atlantic ridge axis to the north of the region. The main boating concern will be showers and storms across the local waters each day. A few waterspouts are also possible over the atlantic waters today. Prevailing flow will lead to more storms pushing off the gulf coast in the afternoons and evenings. Winds and waves could be locally higher in an around any shower or Thunderstorm.
Gulf stream hazards..Lightning, gusty winds, locally higher seas, and waterspouts are possible with Thunderstorms over the gulf stream.

(on/off) Help NOTE: mouseover dotted underlined text for definition| Fxus62 kmfl 191438 afdmfl area forecast discussion national weather service miami fl 1038 am edt Mon aug 19 2019 Update Low-level easterly flow prevails this morning as we remain between the atlantic ridge axis to our north and inverted troughing over the eastern bahamas. Showers and a few thunderstorms will continue pushing inland from the atlantic waters this morning with the dominant atlantic breeze concentrating afternoon convection over inland south florida and the gulf coast region. Mesoscale and sounding analyses reveal the possibility for a few strong thunderstorms this afternoon and evening given the slight uptick in mid upper flow juxtaposed with slightly drier air aloft and good surface heating low-level lapse rates. Although conditions seem mostly supportive of special weather advisory criteria type storms, a marginally severe wind gust or two is possible in any taller thunderstorm cores provided sufficient precipitation loading. Lightning and localized heavy rainfall minor flooding remain concerns as well, particularly towards the gulf coast. Updated pops and sky cover to reflect current trends and the latest output from the convection allowing mesoscale models. Otherwise the forecast is in great shape and no major changes are anticipated through the early afternoon hours. Prev discussion issued 750 am edt Mon aug 19 2019 update... atlantic showers pushing inland may briefly impact the eastern terminals through late morning. While a brief visibility reduction is possible, prevailingVFR is anticipated. Afternoon shower storm coverage should favor interior and gulf coast areas, so left vcts out of the eastern TAF sites for now. Prevailing easterly winds will continue, becoming more light and variable tonight for inland areas. Prev discussion... Issued 330 am edt Mon aug 19 2019 discussion... today: the leading edge of the next moisture push associated with a low level trough moving through the bahamas is currently moving through the central bahamas early this morning. It's already kicking off a few more showers and storms over the local atlantic than we saw this time yesterday, with a gradual uptick expected as we head towards daybreak. Today will be a transitional day as the western atlantic ridge axis continues to lift northwards and we remain under the diminishing influence of the saharan air layer that was in place on Sunday. Coverage today looks higher than yesterday due to the influence of the approaching trough, though it will play more of a factor on Tuesday, as well as cooling temperatures aloft. The atlantic showers and storms will move into the coast through the morning hours, with the better coverage shifting west as the east coast seabreeze moves inland. As with yesterday, convection will pile up along the gulf coast and SW florida interior. Tonight and Tuesday: the perturbations of the western atlantic ridge will be the largest influence on the weather across south florida through the upcoming week. The axis of the ridge will generally be to our north, putting us in prevailing deep, though somewhat light, east southeast flow. A few factors will bring a trend of higher coverage of showers and storms as we go into midweek. First, the saharan dust that was in place will move fully westward, allowing a re-moistening of the local airmass with pwats creeping back towards 2". This moistening will be brought upon by the second |
factor, the combination of a westward moving tropical wave passing to our south Monday night and the low level trough on it's northern end moving into the fl peninsula by Tuesday morning. These features have a midlevel reflection that will erode the western end of the ridge, bringing in a little cooler temperatures aloft. The highest rain chances of the week will likely be Tuesday as the influence of the above factors are maximized. We will still see a diurnal maximum of activity in the afternoon with daytime heating and diffuse east coast seabreeze. While the highest coverage will be across inland SW florida and the gulf coast, locally heavy rain may be a concern for all locations. Wednesday through Friday: the latter half of the week looks to favor a return to more seasonable scattered showers and storms once the wave and trough round the ridge and pass to our west. The ridge will weaken as we end the week, but still exert enough influence to keep us in prevailing light easterly flow. This will continue to push the highest coverage towards the gulf coast and inland SW florida each afternoon. Convection will generally be diurnally driven, developing along the seabreezes in the late morning and afternoons. Next weekend: another tropical wave, currently located around 35w, is forecast to enter the picture as we go into next weekend. Models have this feature tracking a little further north, potentially having more direct impacts in terms of a deep moisture push. Exactly when and in what shape it arrives will determine when enhanced rain chances may return to south florida. For now though, scattered to locally numerous showers and storms will be the forecast. Marine... prevailing east southeast winds will be in place for most of the upcoming week with the atlantic ridge axis to the north of the region. Speeds will generally be 10kts or less, though occasional 10- 15kts is possible across the atlantic. The main boating concern will be showers and storms across the local waters each day. Prevailing flow will lead to more storms pushing off the gulf coast in the afternoons and evenings. Expect locally higher winds and waves near any convection. Hydrology... a lack of widespread coverage the last couple of days has allowed the ground to tolerate heavy rainfall a bit better. Locally heavy rainfall anywhere in south florida could still cause minor flooding over the coming days, but the prevailing flow will tend to concentrate afternoon showers and storms towards gulf coast and southwest florida. Fisheating creek at palmdale continues to slowly rise and is currently at 6.38 feet this morning. The forecast trend is an expectation for fisheating creek to gradually rise over the coming days as additional rainfall falls across the basin. At this time, the forecast remains for the creek to stay below flood stage at palmdale.
