Area Forecast Discussion National Weather Service New York NY 752 PM EDT Sat May 30 2020

SYNOPSIS. A cold frontal passage occurs tonight. High pressure settles over the area on Monday. Weak low pressure and its associated warm front affects the region Tuesday into Tuesday night. A cold front will be nearby late Wednesday into Thursday, with a potential return to high pressure for Friday and into the weekend.

NEAR TERM /UNTIL 6 AM SUNDAY MORNING/. Adjusted POPs every so slightly higher to slight chance over extreme northern sections of our NY zones as a few showers could linger over the next few hours. Otherwise, as one cold front passes e of the area this eve, another over wrn PA will pass tngt. The best mid lvl moisture is progged to remain north of the area, although a couple of sprinkles or a few quick showers could clip parts of Orange, Putnam, and potentially Fairfield counties. The NAM appears to have a good handle on the convection nw of BGM, lending support to the model soln. The NBM with local adjustments was used for temps, with lows mainly in the 50s.

SHORT TERM /6 AM SUNDAY MORNING THROUGH SUNDAY NIGHT/. A cooler airmass builds in on Sun so high temps will be several degrees cooler than Sat. Some sct cu is possible, mainly in the late aftn as the cold pool aloft builds in with steepening lapse rates. 20 kt of nw flow at h85 should be strong enough to hold off the sea breeze. This regime produces high temps much more uniform across the area, with the warmest readings across the srn portion of the cwa as opposed to the nw interior with a deep mixing regime. Dry wx expected to continue Sun ngt with a fairly dry airmass in place along with weak subsidence. The NBM with some tweaks was used both Sun and Sun ngt for temps.

LONG TERM /MONDAY THROUGH SATURDAY/. An blocky pattern will continue to persist to some degree in the northern latitudes of Eastern North America and the Northwestern Atlantic. Much of the period upper level low pressure will remain anchored well north of the region across Eastern Canada, while upper level height rises attempt to get established down to our south and southwest over the Lower Plains, and eventually the Gulf states later in the week. In between these dominant upper level features a semi-zonal upper level jet will race west northwest to east southeast over the region, and at times just north of the region. This will result in relatively weak weather systems embedded in the large scale flow potentially resulting in subtle sensible weather changes from Tuesday through Thursday night. The degree of weakening of this blocking regime will largely determine the timing of and positioning of weak weather systems as they attempt to slide through. Otherwise, most of the extended period should feature dry conditions and temperatures overall averaging near normal. A slight warming trend is then likely later in the period.

With high pressure providing large scale sinking motion over the region to begin the period for Monday and Monday night, you can expect slightly below average temperatures and dry conditions. Little in the way of cloud cover is expected through much of Monday night. By Tuesday morning clouds are expected to quickly increase as a quick moving weather system and its associated warm front approach from the west. A mainly light QPF event is expected with this feature with rain likely beginning some time during Tuesday afternoon in most places and continuing into Tuesday evening. Rainfall amounts look to be not more than a tenth to a quarter of an inch or so at this time. Temperatures will warm up significantly in the lower to mid levels into Wednesday. Cannot rule out a few thundershowers as instability overall will increase into the day on Wednesday, with coverage questionable at this time. Another quick moving system then likely passes just north of the region with its associated cold front slated to come into the region late Wednesday into Wednesday night. Then questions arise into Thursday as to how far south the front will get. Clouds and a shower or thundershower chance could linger through the day on Thursday. By Friday into Friday night some of the global model guidance were attempting to get gradual height rises into the region from the southwest. The degree to which this occurs is even more in doubt now. Weak high pressure will attempt to settle in, but a weak boundary may attempt to get close from the north with the chance of an upper level trough lingering just north of the area. Much of the global guidance now sends another round of height falls into the northeast Friday night into early on Saturday. More substantial upper level ridging thus could get delayed into the latter portion of next weekend or later the following week, resulting in a series of cold fronts to potentially contend with for the late week period. Forecast uncertainty thus increases for late in the period.

AVIATION /00Z SUNDAY THROUGH THURSDAY/. Another cold front will cross the region tonight. High pressure builds in for Sunday.

VFR through the TAF period. W to WSW winds to start will shift to the NW and increase later this evening. G15-20 kt are possible overnight, increasing to G20-25kt during the day on Sunday before gradually diminishing.

OUTLOOK FOR 00Z MONDAY THROUGH THURSDAY. Sunday night-Tuesday Afternoon. Mainly VFR. Tuesday Night-Wednesday. MVFR possible. A chance of showers and a slight chance of thunderstorms. Thursday. MVFR possible. A chance of showers.

MARINE. SCA Advisories have been discontinued on the eastern ocean zones. Winds and seas are expected to be blw sca lvls Sun, although some nearshore gusts around 20 kt can be expected during the day.

Sub-SCA offshore flow will continue into Monday as high pressure builds southwest and south of the waters. The flow will diminish Monday night with ocean seas averaging around 2 ft. The winds will then shift to the south and southwest into Tuesday with non-advisory conditions continuing into Tuesday night and Wednesday as gusts on the ocean approach 15 to 20 kt. Ahead of a cold front late Wednesday into Wednesday night seas may build close to 5 ft. out on the eastern ocean waters, otherwise sub-SCA conditions should prevail for the remaining waters as a southwest fetch continues.

HYDROLOGY. No hydrologic impacts expected through Saturday.

EQUIPMENT. NYC NOAA Weather Radio Station KWO35 (162.55 MHz) is undergoing its final stages of testing, and is operating at full power.

OKX WATCHES/WARNINGS/ADVISORIES. CT . None. NY . High Rip Current Risk until 8 PM EDT this evening for NYZ075- 080-081-178-179. 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.
