(on/off) Help NOTE: mouseover dotted underlined text for definition| Fxus61 kokx 132326 afdokx area forecast discussion national weather service new york ny 626 pm est Wed nov 13 2019 Synopsis High pressure moves offshore on Thursday as a weak warm front passes to the north. This will be followed by a cold front Friday night, and then high pressure for much of this weekend. Low pressure will move east of the area Sunday night into Monday, with another weaker coastal low pressure system potentially passing to the east Tuesday and Tuesday night. Near term until 6 am Thursday morning Dry weather tonight with a strengthening 1030 high building over the region. A mid and high cloud shield continues to progress east from the great lakes, upstate ny, and the appalachians. This could limit slightly the radiational cooling potential tonight. The forecast was not adjusted below guidance as a result, despite the anomalous cold. Some record lows are expected to be broken. If the cloud shield erodes sufficiently and is not as thick as the GFS suggests, lows may be colder than forecast. So far this evening high clouds have pressed east and have entered parts of the region. This first wave of high clouds, generally around 25 kft have thinned out for the most part as they have progressed east over top of high pressure. The next wave of high clouds will be likely be a touch more dense for late this evening and into the first half of the overnight. Will have to monitor this as this may have an impact on how low temperatures get. The current minimum temperature forecast is a touch aggressive when one considers that it will not be completely clear. The feeling as of now is that the cloud cover will be high enough and not thick enough overall to bump up temps for later tonight. Wind speeds were adjusted downward for late in the night as glamp winds appear to be matching obs the best and tend to do better with lighter winds with high pressure essentially overhead. Therefore have held off on any significant adjustments upwards with temperatures for the overnight. Short term 6 am Thursday morning through Thursday night Return flow develops during the day Thursday as the high builds offshore. This will bring a warmer, moist flow into the region. Shortwave energy embedded in the next approaching upper trough may provide just enough lift to produce some pockets of light rain, particularly Thursday night. A blend of the models was used as a starting point for probabilities, which are still low with the best chances remaining offshore. However, did manually increase them Thursday night giving the NAM a bit more weight. No ice crystals in the cloud layer per model time heights, but surface temperatures could be a concern, especially if any precipitation breaks out away from the immediate coasts late Thursday night. Some light freezing rain has been included in the forecast, but the probability in this area remains below 30 percent at this time. The nbm was followed closely for temperatures with some minor adjustments. Long term Friday through Wednesday To begin the period on Friday a weakening cold front will slide through the region. Friday should be mainly dry with near seasonable temperatures. The more noticeable wind shift will occur behind the front by Friday evening as this will serve to bring in another round of unseasonably cold and dry air. This next round of below average temperatures will not be as intense, nor last as long. This will be primarily due to the core of the cold air passing by further north this go around. Therefore this next cold airmass will be shallower than the current cold air mass. Temperatures will still average several degrees below average for Friday night into Saturday, but record or near record cold is not expected for this next shot of cold air. The weekend will begin cold and dry with low dewpoints due to a strong lower level polar air mass. Dry conditions with mainly clear skies will be the rule on Saturday. A stiff northeast wind due to a tightening pressure gradient will lead to wind chill values likely remaining in the 20s through the day on Saturday. With the northeast wind continuing Saturday night wind chill readings will run mainly in the teens Saturday night, before wind chills climb into the lower and middle 30s during the day on Sunday with the air mass modifying. High level moisture will try to move up from the south by late Saturday night into Sunday. A positively tilted trough in the southern branch will then have to be watched for late in the weekend and into early next week. The latest global models by and large are further south initially Saturday night as the system emerges off the southeast coast, and therefore further east later Sunday and Sunday night as the system tries to turn the corner up the coast. Not writing off this system completely in terms of giving at least eastern sections some rain for Sunday night into Monday. As temps warm, especially aloft any precipitation if it occurs would be in the form of rain along the coast, and any precipitation inland could start briefly as frozen but it is doubtful as to how far north and west any precipitation would get with a track off the coast, and possibly well off the coast. With the latest 12z package being further east overall, and made some cosmetic downward adjustments with pops but did not pull out precipitation and rain chances all together. Based on teleconnections and the 12z naefs the slightly more eastward track appears to be the way to go for now. The northern branch will then attempt to become somewhat more active as to reform the trough in the east. Initially in the wake of the previous southern branch system there may be a lack of lower and mid level moisture despite cyclonic curvature aloft developing upstream. Then much of the global guidance attempts to develop an offshore low |
pressure system along with hints at a norlun trough impeding coastal sections. Thought it prudent for the time being to keep some chance of precipitation through Tuesday night before high pressure builds in from the west and southwest into the mid week period. Due to the aforementioned pattern with the possibility of a prolonged NE wind and an easterly swell developing for late in the weekend and early next week minor coastal flooding for some coastal locations cannot be ruled out. A mitigating factor however is that tides will be running astronomically lower late in the weekend and into early next week. Aviation 00z Thursday through Monday High pressure builds tonight and moves offshore on Thursday as a weak warm front passes to the north. Vfr with mainly high clouds tonight. Winds will be light and variable. Vfr on Thursday, although ceilings of 3500-5000 ft may develop along the coast during the morning and continuing into the afternoon. Light winds early in the morning will become s-ssw under 10 kt through the remainder of the day. Outlook for 00z Friday through Monday Thursday night-Friday MainlyVFR, although a few borderline clouds 3-5 kft are possible along the coast Thursday night. Friday night Vfr. NW wind gusts 20-25 kt. Saturday-Sunday Vfr. N-ne gusts around 20-25 kt. Monday MVFR or lower possible in rain wintry mix inland. Ne wind gusts 15-20 kt. Marine Winds and seas will continue to subside this evening, and the small craft advisory was canceled as a result. Winds and seas will then remain below advisory levels through Thursday night with high pressure over the region. Sub SCA conditions are expected on the coastal waters through Friday. Seas will then begin to build late Friday night into Saturday due to a tightening pressure gradient and a developing increasing easterly swell. SCA conditions are expected out on the ocean, and eventually all the coastal waters due to increasing winds during Friday night. With high pressure to the north and low pressure well to the south on Saturday SCA conditions will continue with building ocean seas. Wind gusts may reach gale criteria out on the ocean waters by Saturday night and continue through the remainder of the weekend. By Monday the pressure gradient relaxes and sub SCA conditions will return to the non-ocean waters. Out on the ocean however, seas will remain elevated as SCA conditions will continue mainly due to high seas. Hydrology No hydrologic impacts expected through the forecast period.

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. |
