(on/off) Help NOTE: mouseover dotted underlined text for definition| Fxus61 kokx 182026 afdokx area forecast discussion national weather service new york ny 426 pm edt Sun aug 18 2019 Synopsis High pressure remains over the region through Tuesday with only a couple of weak troughs of low pressure moving in. A cold front approaches Wednesday and moves through Wednesday night. High pressure then builds in through next weekend. Near term until 6 am Monday morning Shortwave lift pushes through this evening with the strongest lift over the northernmost zones. At the same time, capes diminish, but still unstable enough for a chance of strong thunderstorms. Severe storms not out of the question given marginally strong enough winds aloft with a weakly veering shear profile. This would be for mainly the NW half of the forecast area. Still a chance of additional showers and tstms late at night, but probably with less coverage as we continue to stabilize. Patchy fog is anticipated as well. Muggy conditions into this evening expected. A heat advisory has been issued for portions of the tri-state area. See the short term section below for more details. There is a low risk for the development of rip currents at atlantic ocean beaches into this evening. Short term 6 am Monday morning through Tuesday The overall pattern doesn't change all that much for Monday through Tuesday night with a somewhat flat flow aloft interrupted by late-day early evening shortwaves. Showers tstms are possible both days, and again, best chances highest coverage in the afternoons and evenings as lift and instability are maximized. Marginal speed and directional shear would appear to bring at least a low chance of strong to severe storms both days. Regarding temperatures and heat indices, Monday's 850mb temps are forecast to be 18-19c and slightly cooler on Tuesday. Full mix down potential both days will be limited by somewhat high dewpoints at the top of the mixed layer, and for areas nearby the water, a southerly flow. Uncertainty of cloud cover also complicates the high temperature forecast, but thinking it should be at least partly sunny rather than mostly cloudy both days. Surface dewpoints won't have a great opportunity to mix out both days given the wind direction and dewpoints aloft. So with highs generally in the upper 80s to lower 90s and dewpoints in the lower 70s, heat index values are expected to reach at least 95 for most of the forecast area on Monday, but with less overall coverage on Tuesday. Will go with advisories where the criteria is expected to be met for the Sunday- Monday period, and let subsequent shifts assess the need to add Tuesday as appropriate. There is a moderate risk of rip current development at atlantic beaches on Monday. Long term Tuesday night through Sunday Hot, humid and unsettled weather continues through wed, possibly into Thu depending on the progression of a closed low traversing eastern canada and its associated cold front. 12z nwp model suite is in good agreement with the overall upper pattern across north america during the long term period, although there are some slight timing differences and amplitude differences, especially with the eastern canadian low. Heights begin to fall Tue night as the closed low over hudson bay drops into southern quebec and ontario. There will be shortwaves moving around the trough that extends into the lakes and northeast, but the details on the timing of these are still in question. Thus, have chc pops Tue night into Wed morning. Better chances for showers tstms will come Wed aftn night with |
the development of a pre frontal trough west of nyc and an approaching cold front. Too early to say whether there will be severe weather, but it is a possibility if things align right. Front may only be about halfway through the forecast area by thu morning so could have additional convective activity across eastern locations on Thu before it clears the area. A cooler and more comfortable airmass filters in behind the front for Fri into the weekend. Upper troughing will linger into sat with another shortwave progged to move through, although there may not be enough available moisture for any pcpn. Have kept forecast dry for now. Temps are expected to be near to slightly below normal levels during this time. Aviation 20z Sunday through Friday Low pressure passes to the south and east through tonight. Vfr late this afternoon into the evening, outside of an isolated shower or thunderstorm which could briefly cause a reduction in visibilities and ceilings. For tonight, expect stratus fog once again, mainly east of the nyc terminals, and possible patchy fog at hpn and swf. Once the stratus and fog burn off,VFR once again Monday morning. Winds will be southerly around 10 kt. Speeds diminish after sunset. Outlook for 18z Monday through Friday Monday afternoon-Monday night MainlyVFR, but MVFR is possible in any showers or thunderstorms. Tuesday-Thursday MainlyVFR, but sub-vfr possible in showers or thunderstorms. Thursday night-Friday Vfr. Marine A light pressure gradient will maintain relatively tranquil conditions on all waters through Tuesday night. Sub advsy conds are expected to prevail through the period, outside of tstms. Wind gusts and seas on the ocean could approach 25 kt Wed night and 5 ft Wed night into thu, although feel that guidance was overdoing the seas on SW flow so have knocked them down a foot for now.

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. |
