(on/off) Help NOTE: mouseover dotted underlined text for definition| Fxus62 kmfl 181131 aaa afdmfl area forecast discussion... Updated national weather service miami fl 731 am edt Tue jun 18 2019 Aviation There could be a few showers around the east coast TAF sites this morning before an increase in showers and thunderstorms during the afternoon hours due to the heating of the day. Kapf TAF site should see the showers and thunderstorms mainly this morning. The vis and ceiling should remain inVFR conditions, but could fall down into MVFR or even ifr conditions with the passage of the showers and thunderstorms. Prev discussion issued 325 am edt Tue jun 18 2019 discussion... today and tonight... mid to upper troughing will slowly progress towards the western bahamas as 15-20 kt of s-sw 850 mb flow brings a continued moisture feed across southern florida. This flow regime will advect a broken band of showers and storms originating from cuba north through our area early this morning with primarily light to moderate rainfall. With this activity arriving earlier than on previous nights, a early to mid-morning break in the rain is possible (as advertised by a consensus of the mesoscale models) before isolation brings a renewed round of showers and storms during the afternoon. Given the mentioned 850 mb flow, it appears that the east coast metro areas will be targeted yet again for the greater rain chances. Slow storm motions, potential backbuilding, a deep warm cloud layer, and 850 mb moisture flux convergence all point towards heavy rain potential. Thus, urban flooding is the primary weather related hazard for today, given given 24 hour radar estimated gauge bias corrected rainfall amounts of 1-3". As such, it shouldn't take much to cause additional issues today should repeated rainfall rounds impact a particular area. Secondary concerns for today are lightning and gusty winds which are possible with any of the taller cores. As the mid upper wave pulls away later tonight precipitable water values should drop a bit, with recent model solutions suggesting a bit drier conditions are expected than with the previous nights. There should be enough cloud cover and precipitation today to temper afternoon highs just a bit, although most areas should still be able to reach the upper 80s in between showers and storms. Overnight lows will be in the 70s. Wednesday... with the mid to upper trough axis located to our east, additional low amplitude perturbations will continue, with a renewed push of deeper moisture arriving via ssw low-level flow. At the surface we'll be under the influence of the western atlantic subtropical ridge, whose axis will branch west across south florida. Expect a dominant atlantic sea breeze given this regime, with convective initiation along it during the late morning to early afternoon hours. Thunderstorms should have a tendency to drift more towards the northwest given the steering flow, targeting eastern broward and palm beach counties with the greatest afternoon evening rain chances. Of course, all portions of our area will see scattered showers and storms at a minimum given the coupled deep moisture, low- level sea breeze forcing, and slightly better than average (for this time of year) upper support via the passing waves aloft. With the coverage being more diurnal and scattered in nature, look for a warming trend to begin (especially for the eastern interior and metro areas), with highs likely climbing back into the 90s. Thursday and Friday... |
a low pressure system will trek across the eastern 2 3 of the conus, while a zonally elongated mid-level ridge expands from the northern caribbean sea into the gulf of mexico. This will support strengthening surface ridging across south florida with a slight decrease in tropospheric moisture. Shower and storm coverage should decrease as a result, while becoming more diurnally driven with sea breeze collisions as the focusing mechanism. Weak ssw steering flow should favor the northeast and lake regions for the greatest late afternoon evening storm coverage. Temperatures should remain on the warm side, trending towards above normal for portions of the east coast metro. Maximum heat index values could eclipse 105 degrees for some areas during this time. Saturday through Monday... ridging aloft will prevail for much of this period, punctuated by a wave that should drift from the bahamas towards cuba over the weekend. Deep layer ridging along with slightly drier conditions should prevail, with only the typical sea breeze driven convection. With easterly low-level winds picking up later in this period the warmest temperatures should shift more towards the interior and west coast. Near to above normal readings should continue. Marine... numerous showers and thunderstorms are likely over the waters today, with coverage gradually decreasing this week. Lightning, gusty winds, and waterspouts are all possible, so mariners should exercise caution. Southerly winds are expected today, with south to southwest winds prevailing through Friday. Seas will be 3 feet or less. Aviation... periods of showers and thunderstorms are expected at each terminal through the TAF period. Perhaps there could be a bit of a break later this morning once this line from the south moves through, with another round of showers thunderstorms late morning into the afternoon.VFR conditions are expected outside of convection. Hydrology... bias corrected radar rainfall estimates indicate 1-3 inches of rain has fallen on average across much of the east coast metro areas during the past 24 hours. Periods of showers and storms producing heavy rainfall appear possible yet again today. Given somewhat slow storm motions, potential backbuilding, a deep warm cloud layer, and 850 mb moisture convergence urban street flooding will again be a concern today. The best time for heavier rain appears to be from late morning through the late afternoon hours. Motorists should exercise caution. Remember, never attempt to drive through flooded roadways.

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program. |
