At times, speeds may increase in pressure surges, particularly overnights in the atlantic, and small craft operators may need to exercise caution. The surge looks particularly robust Thursday night, and a small craft advisory may be warranted at that time.

Area Discussion for - Miami-South Florida, FL
(on/off) Help NOTE: mouseover dotted underlined text for definition| Fxus62 kmfl 170715 afdmfl area forecast discussion national weather service miami fl 315 am edt Wed oct 17 2018 Discussion Short term (today through Friday) relatively benign weather pattern persists across south florida this week. Few showers have pushed inland from the atlantic into mainly miami-dade county early this morning, and mesoscale guidance suggests a few more will impact the east coast through the morning before transitioning to western northwestern areas in the afternoon. Coverage will be relatively sparse, as pwats are not exceptionally high and easterly flow is strong enough to negate significant sea-breeze boundary development. Synoptically, deep layer ridge that has dominated since last weekend will prevail through the short term, bringing fairly dry conditions with only isolated to scattered showers and a few thunderstorms, focused east overnights and mornings, and west during the afternoons. Temperatures will be above normal for october, with maxima in the upper 80s to low 90s and minima in the 70s to around 80f. Some records will be threatened; see climate section below. Long term (Friday night through Tuesday) at least subtle changes continue to be hinted at by global guidance for the weekend and early next week. Upper-ridge should weaken and drift southeastward, allowing some influence in south florida from mid-latitude longwave trough that will progress through the eastern CONUS this weekend. A weakening cold front is forecast to approach central florida Friday night into Saturday, then be reinforced by another weak front that appears poised to reach south florida later Sunday into Monday. Although both gfs and ECMWF show the front having little dynamical support or significant moisture pooling for more than scattered convection, they differ in the magnitude of any cooler (i.E. Drier) air behind the front. ECMWF suggests a slightly more pronounced fropa, with early next week yielding dewpoint values in the 60s and temperatures down toward normal. GFS has front stalling over far southern florida will little in the way of drier air and only lower temperatures to result from curbed diurnal heating from clouds scattered showers. Marine With high pressure dominating south florida waters, moderate east wind will prevail into the weekend, with only isolated to scattered showers and a few thunderstorms. At times, speeds may increase in pressure surges, particularly overnights in the atlantic, and small craft operators may need to exercise caution. The surge looks particularly robust Thursday night, and a small craft advisory may be warranted at that time. Aviation With high pressure in place easterly flow will continue to persist throughout the period. Showers over the atlantic continue to quickly move eastward over the east coast sites this |
morning. Showers will shift towards interior and west towards apf this afternoon. Overnight, partly cloudy skies with winds around 10 knots. Beach forecast East wind of 15 to 20 mph has persisted for several days and will continue for several more. This has increasingly favored rip current generation along the east coast and there is now a high risk of rip currents on atlantic beaches today. A moderate to high risk will likely continue on the east coast into the weekend. Fire weather Fairly strong easterly wind will lead to excellent dispersion over interior south florida for at least the next couple of days, with indices exceeding 75 today over interior collier county. Values above 75 are likely over portions of the interior again on Thursday. Climate Record high minima were set at all 3 east coast climate sites on Tuesday, october 16th. - at miami, the low temperature of 80 degrees broke 1933's daily record warm low temperature of 79 degrees. - at fort lauderdale, the low temperature of 80 degrees broke 1925's daily record warm low temperature of 79 degrees. - at west palm beach, the low temperature of 80 degrees tied the daily record warm low temperature, last set in 2016. Persistent onshore flow from the warm atlantic threatens additional warm records over the next several days. For today, Wednesday, october 17th, the record warm minima are as follows: city record date miami 79 2016 fort lauderdale 79 1998 west palm beach 80 2016 naples 75 2007 Preliminary point temps pops West palm beach 89 77 88 77 20 20 20 30 fort lauderdale 88 80 88 80 20 30 30 30 miami 89 78 88 78 20 20 20 30 naples 90 74 90 73 20 10 20 10 Mfl watches warnings advisories Fl...

Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors.

It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. 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. |
