Area Discussion for - Miami-South Florida, FL
(on/off) Help NOTE: mouseover dotted underlined text for definition| Fxus62 kmfl 180523 afdmfl area forecast discussion national weather service miami fl 123 am edt Sun aug 18 2019 Aviation Vfr conditions will prevail throughout the forecast period. Light and variable winds for the rest of the night will increase out of the southeast to 10 to 15 knots by Sunday afternoon. At kapf, winds will shift around to the southwest in the afternoon as a gulf coast sea breeze moves inland. Scattered showers and thunderstorms are possible across the interior and west coast sections. Chances are too low for tafs for east coast terminals. Prev discussion issued 918 pm edt Sat aug 17 2019 update... convection continues to trend down this evening with some remnant cells over the everglades making up the last convection for now. The convection over cuba today was more limited today which means that there should be a lack of an outflow to get as much convection going over the waters tonight. Tweaked the forecast a bit to kept some remnant rain chances over the everglades over the next few hours. Updated zones have been transmitted. Have a great Saturday night! prev discussion... Issued 755 pm edt Sat aug 17 2019 aviation... primarilyVFR conditions are expected through the period. Another round of showers and thunderstorms are expected across the area tomorrow, but the best coverage should shift more towards the interior and west coast. Therefore the east coast TAF sites have been left dry for now, although an isolated shower or storm cannot be ruled out along the seabreeze. Prev discussion... Issued 404 pm edt Sat aug 17 2019 convective focus shifting to SW florida this week... discussion... this afternoon and evening: we saw a peak in convective activity over the last few hours with things generally winding down as activity pushes northward along the southerly flow. Boundaries will provide the focus for any remaining convection, particularly as the afternoon winds down into the evening. Overnight: tonight should be drier than last night with a noticeable lack of convection over cuba this afternoon to fuel an outflow boundary that could initiate convection over the waters again tonight. Slightly drier air will also help cut off the amount of convection but the warm, rich surface moisture over the atlantic and gulf waters will provide an environment where shallow convection could definitely persist overnight and any interactions by that convection with boundaries could lead to some strong thunderstorms. For the forecast, most high resolution guidance was fairly dry so adjustments were made for the gridded forecast to illustrate that low end rain and thunderstorm chances focused over the waters tonight. Sunday: slightly drier air advecting into the area from the east on Sunday will help to cap convective coverage but convection should still be able to get going with the sea breezes. The easterly flow regime will favor the convective focus over the interior and west coast. Morning showers becoming early afternoon thunderstorms along the sea breezes near the coasts are in the forecast with the majority of the rain chances over southwest florida, particularly inland portions along the state road 29 corridor, on Sunday afternoon. Temperatures will continue to be warm with a degree or so above the consensus blend preferred for the forecast in most areas. Monday-Wednesday: with the surface ridge of high pressure reaching |
into the region from the atlantic to start the week, the surface trough and associated pooled moisture will remain north of the area. A weakness in the mid to upper level ridge will begin to develop which may allow a trough to return over the peninsula of florida. This small shift in pattern could allow for an increase in convective coverage but the easterly to southeasterly pattern through mid- week should keep the focus of convection over southwest florida and the interior. The national hurricane center continues to monitor the surface trough to our north in case tropical development were to occur (formation chances per the 2 pm edt tropical weather outlook remain low through the next 5 days). To the south, a tropical wave pushing across the caribbean could bring some additional moisture to the region, particularly if a surface trough breaks off the northern portion of the wave and moves into the region Monday into Tuesday. Thursday-Saturday: easterly to southeasterly flow will persist into the end of the week with a pattern that favors a continued convective focus over southwest florida and the interior. Another northern trough from a tropical wave traversing the caribbean Friday into Saturday could again bring additional moisture into the region to close out the extended forecast period. With these waves, the convective activity could be more widespread temporally instead of focused along the more normal diurnal pattern. Marine... a more typical pattern for august with south southeast flow this weekend becoming east southeast into the upcoming week as the ridge axis from atlantic high pressure builds over the region and shifts northward. With prevailing speeds generally less than 10kts, seas will be 2 feet or less for all waters. The main boating concern will remain scattered showers and storms, where winds and waves could be locally higher in and around any activity. Hydrology... while much of the area remains saturated, a lack of widespread coverage the last couple of days has allowed the ground to tolerate heavy rainfall a bit better the last couple of afternoons. With a shift to easterly to southeasterly flow, the greatest concern for flooding from repeated rounds of afternoon convection day after day will shift from the east coast metro towards southwest florida. Locally heavy rainfall anywhere in south florida could still cause minor flooding over the coming days, but those with interests over in southwest florida particularly should monitor conditions and the forecast over the coming week. Fisheating creek at palmdale is currently at 6.14 feet with additional heavy rainfall from thunderstorms over portions of the basin in northern glades and highlands counties occurring the afternoon. The forecast trend is an expectation for fisheating creek to gradually rise over the coming days. At this time, all the ensemble guidance continues to maintain the creek below flood stage at palmdale.
