(on/off) Help NOTE: mouseover dotted underlined text for definition| Fxus61 kokx 221734 afdokx area forecast discussion national weather service new york ny 134 pm edt Thu aug 22 2019 Synopsis A cold front will approach today and pass offshore by Friday morning. High pressure builds to the north this weekend and across the canadian maritimes early next week. A frontal system approaches by mid week next week. Near term through tonight Bumped up high temperatures by a couple of degrees, mainly across long island, but also for a few other locations based on latest obs and a mostly sunny partly cloudy sky. A cold front approaches today. Ahead of this front, hot and humid weather will continue. A prefrontal trough through the city and into ct will remain nearly stationary before being forced to the east this evening. Behind the trough, dewpoints may lower another degree or two as the low level flow comes in off the land. Elsewhere, dewpoints mostly 70-75. No changes to the heat advisory with the heat index still expected to be around 95 for much of the area within the advisory. The area is in a marginal risk for severe for this afternoon and evening. The increasing shear late supports organized cells. However the models depict some NVA coming through at peak heating, so this may suppress development for most of the day. The jet gets close enough to support activity tonight. Some of this could be strong to severe, mainly the southern third of the area, until the front comes through. Thereafter, showers are possible with the jet still providing upper level divergence. There is a moderate rip current risk today. Short term Friday Lingering morning showers are possible per the 00z nam, GFS and ecmwf. Although the upper jet will be supportive of activity through the day, the stable airmass building in will counteract this. As a result, clearing is expected to occur from the northwest through the day, and temperatures will mix out to |
around 80. The humidity will be much lower with the drier airmass building in. There is a moderate rip current risk Friday. Long term Friday night through Wednesday Models, except the nam, are in general agreement with handling of a sw to NE oriented trough and eventual closed low over the northeast this weekend, as sfc high pressure builds to the north. Dry, cooler and less humid air will be ushered in for the weekend, with temperatures several degrees below normal. As the upper low passes overhead by Sunday, the sfc high moves east and easterly wind flow will moisten the lower levels of the atmosphere. With this increase in low level moisture and upper cold pool overhead, a pop up shower is possible on Sunday. This upper low traverses east as next trough begins to approach from the upper mid west early next week. This upper trough slowly lifts north in central canada, so do not foresee a huge rain event by mid week as sfc frontal boundary weakens as it approaches due to lack of upper support. As such, generally dry weather conditions are anticipated early to mid week next week. As mentioned, cooler than normal temperatures can be expected this weekend, and possibly into Monday. These temperatures begin to creep up closer to normal as the upper low passes east toward mid week next week. Aviation 18z Thursday through Tuesday A cold front will move through late tonight into Friday. MainlyVFR and dry conditions expected the remainder of this afternoon. Showers and thunderstorms are possible late this afternoon with the highest chances later this evening moving from NW to se. With these, brief MVFR to possibly ifr conditions as well as potentially gusty winds will be possible. Regarding winds, SW flow of 5-10 kts for most terminals initially will become more S with sea breeze development in the afternoon with a slight increase in wind speed. A few gusts to 15-20 kt will be possible late afternoon into the early evening along the coast. Winds will become more w-nw at 5-10 kt tonight after the cold frontal passage.

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. |
