(on/off) Help NOTE: mouseover dotted underlined text for definition| Fxus61 kokx 200136 afdokx area forecast discussion national weather service new york ny 936 pm edt Mon aug 19 2019 Synopsis A weak cold front will slowly move through the region during the evening, and into late tonight. High pressure builds briefly across Tuesday with a wave of low pressure developing late Tuesday and approaching Tuesday night. A warm front will move north of the area Wednesday. A cold then slowly approaches Wednesday night and moves through Thursday night. High pressure builds Friday and remains into the beginning of next week. Near term until 6 am Tuesday morning A weak cold front will continue to slowly cross the area tonight. With any lingering showers well offshore and northerly flow in the wake of the front ushering in drier air, conditions are expected to remain dry through the rest of the night. Overnight lows will generally range from the upper 60s to lower 70s, with a few readings in the mid 60s possible across outlying areas. Short term 6 am Tuesday morning through Tuesday night High pressure builds across the area with a northerly surface flow allowing dew points to be lower and temperatures to be a few degrees cooler than Monday. Overall, a little less hot and humid with heat indices reaching a MAX in upper 80s to near 90. Showers and thunderstorms return Tuesday evening as a wave of low pressure approaches and moves across the area. High temperature Tuesday will be in the upper 80s to near 90 with night time lows in the low to mid 70s. There is a low risk of rip currents at ocean beaches for Tuesday. Long term Wednesday through Monday A longwave upper trough across eastern canada will be slowly digging into the upper midwest and northeastern states Wednesday into Friday, with the eastward progression slowed by a ridge remaining in the western atlantic. Vort maxes will be rotating through the upper trough. Meanwhile, at the mid and low levels, the area remains on the western periphery of the bermuda high. A slightly cooler and drier airmass will be in place early Wednesday, then warm advection sets up early and a warm front is expected to push through the region. There is some uncertainty as to the timing and areal extent of precipitation Wednesday and will depend on the energy rotating through the upper trough. The area will destabilize by the afternoon and shear and lapse rates will support the possibility of stronger storms. With the area currently in a marginal risk for Wednesday have added heavy rainfall and gusty winds in the afternoon and into the early evening. With the airmass as warm as Monday decided to lean toward the much warmer GFS guidance and even raised temperatures for Wednesday highs. Heat indices will therefore once again peak into the mid 90s. With the slower progression of the upper low and cold front, there will be chances of precipitation remaining into Thursday. The front may even stall for a time Thursday, before pushing |
through Thursday night as ridging does build to the west, and the cooler and drier airmass moves the front through the area. Canadian high pressure builds for Friday through the beginning of next week with a much drier airmass. Aviation 02z Tuesday through Saturday High pressure builds overnight into Tuesday. Vfr conditions are expected overnight and Tuesday. An isolated shower or thunderstorm is possible in the afternoon. Winds will be light as they veer from SW to N tonight. NE winds Tuesday morning will shift to the S SE by afternoon. Outlook for 00z Wednesday through Saturday Tuesday night-Thursday MainlyVFR, but sub-vfr possible in showers or thunderstorms. Thursday night-Saturday Vfr. Marine Conditions are expected to remain below SCA criteria for the waters through Tuesday with sub small craft conditions expected Tuesday night. An increasing south to southwest flow Wednesday into Wednesday night ahead of an approaching cold front will allow for ocean seas to build to SCA levels by late Wednesday night into Thursday. The cold front will pass through the waters Thursday night, with winds shifting to the northwest. Ocean seas will then subside below SCA levels by Friday morning. Winds across the forecast waters are expected to remain below SCA levels Wednesday through Friday. Then Friday night through Sunday winds and seas will remain below SCA as high pressure builds into the region. Hydrology No hydrologic impacts are expected at this time 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. |
