(on/off) Help NOTE: mouseover dotted underlined text for definition| Fxus61 kokx 231134 afdokx area forecast discussion national weather service new york ny 734 am edt Fri aug 23 2019 Synopsis A cold front continues to move to the south of long island this morning. High pressure builds to the north this afternoon through the weekend, and across the canadian maritimes early next week. Low pressure may pass south and east of the local area during the middle of next week, followed by a slow moving cold front late in the week. Near term until 6 pm this evening Scattered showers currently streaming across the lower hudson valley and southern connecticut will gradually sink south and east through the morning as the cold front moves offshore and upper level support gradually wanes. Increased pops across much of the area through at least mid morning as the front so far has been slower to progress than initially thought. Still thinking that the bulk of the precipitation moves offshore by noon or shortly thereafter. Otherwise the forecast remains on track, with lower dewpoint air beginning to advect into the interior behind the front. The next forecast challenge today will revolve around the degree of cloud cover. The proximity of the upper jet will likely be enough to support abundant middle and high level cloud cover well into the afternoon. This is supported by bufkit time heights of the nam, hrrr, rap, and GFS indicating a high amount of moisture from around 15 kft to 30 kft. This moisture does not diminish until this evening and the best chance for seeing significant clearing would be across the NW interior late in the day. Have gone with mostly cloudy conditions through the day for much of the area. High temperatures will be in the 70s today, much cooler than recent days. There is a moderate risk of rip currents at atlantic ocean beaches. Short term 6 pm this evening through 6 pm Saturday The core of the strongest winds aloft push offshore this evening. The bulk of the middle and upper level cloud cover should follow with clearing skies. High pressure also builds closer to the northeast as the upper trough settles over new england. With mostly clear skies, light winds, and a dry airmass, low temperatures should fall well into the 50s inland and near 60 along the coast. The nyc metro may only fall into the middle 60s. Saturday will feature high pressure and temperatures a few degrees |
below normal for this time of year. Highs will reach the middle and upper 70s. There will likely be just a few to scattered fair weather clouds as the atmosphere overall is dry through the afternoon. There is a low risk of rip currents at atlantic ocean beaches. Long term Saturday night through Thursday High pressure builds north of the region Saturday night, then continues to move east into the canadian maritimes through the day on Monday. This will create an environment favorable for the development of stratus and drizzle light rain as easterly flow sets up over the region. Several models indicate the potential for light qpf during the Sunday-Sunday night timeframe, with the best chances from nyc on east. As the high moves offshore on Monday, an area of low pressure developing along the southeast coast will begin to lift to the north, while at the same time a trough will begin digging across the northern plains. Significant differences remain with the timing and amplitude of the upper trough as well as with the strength, timing, and track of the low as it lifts north. While the model consensus continues to track the coastal low south and east of the local area, it will have to be monitored for tropical development through the weekend. A cold front then approaches the area late in the period, although the timing of this feature remains uncertain due to the aforementioned differences aloft. With the potential for plenty of cloud cover, temperatures on Sunday and Monday will be several degrees below normal, with highs generally remaining in the mid 70s. Temperatures then gradually moderate through the mid week period. Aviation 12z Friday through Tuesday A cold front settles just south of the region as high pressure builds to the north. Patchy morning stratus may result in brief MVFR conditions. Otherwise,VFR with lingering scattered light showers expected this morning, tapering off and passing south by afternoon. Mid and high clouds are then expected this afternoon. Clear at night. Northerly winds around 10 kt will lighten somewhat as the morning progresses. These winds may back to the W NW for a short time in the afternoon, but then shift back to the N NE by evening around 10 kt.

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. |
