10/6/2018 Colors of tide XTide graphs changed to emphasize that they were upgraded. See next note. Comments welcome. 10/4/2018 I have fixed XTide and updated the harmonic files. There were some name changes so you might have to click EDIT to find the new station name. |

(on/off) Help NOTE: mouseover dotted underlined text for definition| Fxus61 kokx 222344 afdokx area forecast discussion national weather service new york ny 744 pm edt Wed may 22 2019 Synopsis High pressure continues to move offshore tonight as a cold front approaches from the midwest. The front passes through the area Thursday night. High pressure returns to the region for Friday and Saturday. A frontal system will pass through the region late Saturday into Sunday. The front will stall to the south of the region Monday with a wave of low pressure passing through Monday night. High pressure returns for Tuesday and Wednesday. Near term until 6 am Thursday morning Main update this evening to update sky cover, as an opaque area of cirrus is moving into the lower hudson valley and will quickly spread eastward. High temperatures seem to have peaked later in the day, allowing deeper mixing and lower dew points than previously forecast. Otherwise, forecast remains on track with seasonable temperatures and a chance of showers tonight. Previous discussion follows. Both the upper and surface ridges will translate east tonight with a return southerly flow developing by this evening. This will result in gradually increasing low-level moisture with overnight lows near or just above seasonable levels. Warm advection on the backside of the departing ridge will allow for increasing mid and upper clouds overnight along with a chance of showers. The best chance will be from nyc and points west as drier will be slow to erode to the east. Rainfall amounts will be light and generally less than a tenth of an inch. Short term 6 am Thursday morning through Thursday night Early morning showers will become isolated by afternoon as the warm advection wanes. Any rain in the morning should be on the light side. The potential for a round of more significant convection arises during the late afternoon and early evening hours on Thursday. An upper low north of the great lakes on Thursday will track ese, sending height falls into the region. This coupled with moistening low-levels will destabilize the airmass. Their are mixed signals from the guidance during this period as to whether all the ingredients will come together at just the right time to erode a low-level cap and overcome dry air in a deep-layered westerly flow aloft. Additionally, the best dynamics will reside north of the area. Mid level lapse rates do steepen to |
around 7-8 deg c km and 0-6 km bulk shear is around 50 kt. Href members show varying solutions with most in the camp of the convection being scattered in nature. There is also the question as to whether the shear is sufficient to maintain a cold pool to push through the maritime airmass. So yes, there could be a few strong and or severe thunderstorms, but that should mainly be to the north and west of nyc. The convection will likely dissipate as it approaches the coast. The best timing looks to be between 6 and 10 pm, from west to east. Warm advection during the first half of the day will result in mostly cloudy skies, but there should be some breaks in the afternoon. This will also be a factor into how much we can destabilize. Gusty s-sw winds ahead of the front will get up to 25 mph, mainly near the coast. Highs will be nearly seasonable levels, in the upper 60s at the coast, to the mid 70s north and west of nyc. Cold front passes through between 10 pm to 1 am Thursday night with gusts NW up to 25 mph developing toward daybreak. Long term Friday through Wednesday High pressure builds across the region on Friday and most of the day on Saturday, so expected dry conditions with temperatures in the mid to upper 70s on Friday and upper 60s and lower 70s on Saturday. A cold front will then approach the region Saturday evening and overnight, bringing a threat of showers and thunderstorms across the area. The front should push south on Sunday keeping the area under a slight and chance probabilities of showers Sunday and into memorial day. Temperatures on Sunday will be in the upper 70s to mid 80s with temperatures on memorial day in the mid to upper 70s. Dry conditions return on Tuesday and Wednesday as high pressure builds into the region. Temperatures on Tuesday will start out in the low 70s then warm up into the mid to upper 70s on Wednesday. Aviation 00z Thursday through Monday High pressure just offshore moves farther out to sea into tonight. Vfr through this evening with winds at 10kt or less. For Thursday, a few showers possible within a few hours either way of daybreak, but mostlyVFR. Tstms and sub-vfr conds possible late aftn early evening.

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. |
