Fxus61 kokx 250212 afdokx area forecast discussion national weather service new york ny 1012 pm edt Sun mar 24 2019 Synopsis A cold front approaches the region tonight, and moves across the area Monday morning. High pressure then slowly builds from the north and west before settling over the region on Wednesday. The high pressure then shifts offshore late in the week ahead of a slowly approaching frontal system. Near term until 6 am Monday morning Only minor updates needed mainly to reflect current temperature and dew point trends. A weakening shortwave approaches and moves across the area tonight. This shortwave will push a cold front across the area late tonight early Monday morning. Clouds will lower and thicken late this evening and overnight. Dry air remains below 5-6 kft, and upstream observations suggest any mid level precipitation is struggling to reach the ground. In addition, most model solutions continue to remain mostly dry as the front trough get sheared out, but cannot rule out a passing light shower or sprinkle as the front moves through. If precip occurs, some of the higher elevations over the interior could see a few snow flakes. With the clouds, and a light west southwest wind, temperatures will fall only into the mid 30s to lower 40s. Short term 6 am Monday morning through Monday night The front should pass south of the area early Monday morning. Once the front passes through, canadian high pressure builds across the great lakes region. Temperatures climb to around 50 Monday afternoon as skies clear out across much of the region. The far southern portion of the CWA may see clouds hang around for much of the day as low pressure passes well south of the region. Temperatures fall into the 20s Monday night under clear skies. Long term Tuesday through Sunday Below normal temperatures will settle across the region on Tuesday as polar high pressure builds from the north and west. Apart from a few wisps of cirrus, skies will generally be clear, with winds gradually decreasing through the day, setting the stage for favorable radiational cooling conditions overnight. Expect highs in the upper 30s to mid 40s, and lows in the 20s with the exception of the nyc metro and immediate suburbs, where lower 30s will be more common. By Wednesday, increased subsidence as deep layer ridging builds directly over the region will allow for a continuation of clear skies, but warmer temperatures closer to climatological normals. The surface high shifts offshore late in the day, allowing onshore flow and warm advection to return. Despite calm winds and clear skies, lows should be a few degrees warmer than the previous nights.

The warming trend then continues into late week with strong warm advection in southwest flow between the departing high and a slowly approaching cold front. Although the flow off the cold ocean will keep coastal areas in the 50s, the interior will likely see high temperatures in the 60s, possibly even near 70 by late week. Similarly, low temperatures will be progressively warmer each day. There remains significant uncertainty with the timing of the cold front for late week, which will likely struggle to advance eastward given the strong deep layer ridging to the east. For now, will keep low end chances of precipitation. Additionally, several days of onshore flow may allow for the development of marine stratus, leading to daytime highs a few degrees colder and lows a few degrees higher than currently forecast for coastal areas. Will continue to monitor. Aviation 02z Monday through Friday A cold front approaching from the NW will pass through the area late tonight, followed by building high pressure. Vfr through the TAF period. SW winds less than 10 kt overnight, becoming light and vrb in spots. Timing of winds shifting to the w, then NW could be off by an hour or so. Directions expected to remain right of 310 degrees magnetic aft 11-12z. Outlook for 18z Monday through Friday Monday through Friday Vfr. S-sw gusts 20 kt possible thurs. Marine A few occasional gusts to 25 kt, especially on the far eastern ocean waters may be possible this evening. Otherwise, expect winds to continue to subside. A cold front then approaches tonight and passes to the south on Monday. Northerly winds increase behind the front late Monday and Monday night. Winds may reach SCA conditions Monday night into early Tuesday morning, however it looks short lived and marginal, so will not hoist any new headlines at this time. Conditions then quickly become tranquil, as high pressure settles over the waters into Wednesday. The high then shifts eastward into the late week, allowing a return to a breezy s-sw flow and a developing s-sw swell that will allow seas to continue to build into the weekend. Hydrology No hydrologic impacts are anticipated for the next 7 days. Equipment Nyc NOAA weather radio station kwo35 (162.55 mhz) remains off the air. Okx watches warnings advisories Ct... None. Ny... None. Nj... None. Marine... None.

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.
