Version 3.4 |
6/25/2017 - NOAA is having a major issue that impact the 7 day forecast load times. Many users are reporting problems. The issue has been reported. 5/23/2017 - Worked with NOAA again to speed up the 7 day forecast load times. Thanks to them for being responsive. 5/19/2016 - There were issues with the 3 day airport observation history. I switched to another data source. Let me know if you see any issues with the data feeds. |

(on/off) Help NOTE: mouseover dotted underlined text for definition| Fxus61 kokx 220010 afdokx area forecast discussion national weather service new york ny 810 pm edt Mon aug 21 2017 Synopsis High pressure moves offshore tonight. A cold front approaches from the west Tuesday and passes through Tuesday night into Wednesday morning. High pressure builds in behind the cold frontal passage on Wednesday and remains in control through the end of the week with a much drier and cooler airmass. Near term until 6 am Tuesday morning Scattered convection over eastern pa will gradually approach the lower hudson valley this evening. However, loss of heating should help limit intensity and coverage. Will continue to show mainly slight chance pops with low chance for the western half of orange county. The hrrr and 3-km NAM support this activity dissipating through 03z. While there will be a mid-level shortwave, do not foresee any convection after midnight as the best lift may stay to our south and west. High resolution models support this idea, with any convection staying to the south. Otherwise, high pressure will continue moving offshore. A mav nam MOS blend looked good for low temperatures, and muggy conditions should prevail with dewpoints around 70. Short term 6 am Tuesday morning through Tuesday night The shortwave should still be over the tri state area during the morning, so cannot completely rule out a shower storm during this time. In the afternoon, subsidence behind the shortwave will work against convective development. A surface trough over the interior could still provide a focus for convergence. Will go with a slight chance to chance for showers and storms, with the higher chances over the interior. Some thunderstorms may be strong to marginally severe with bulk shear of about 30 kt and sufficient CAPE values forecast. 850mb temps are forecast to be around 18-19c which should translate to high temperatures in the low-mid 90s for the typically warmest spots across the city, NE nj and adjacent areas given the expected cloud cover and wind flow. With winds at a southerly component and 850mb dewpoint temps forecast at mostly 14-17c, chances of mixing out and having surface dewpoints drop more than a degree or two in the afternoon are slim. Heat index values are therefore expected to range in the 90s to around 100. With Wednesday's heat index values expected to fall short of all advisory criteria, will issue a heat |
advisory for the 1-day heat index criteria of 100. Will go with the advisory over the city, southern westchester county and parts of ne nj. A cold front moves into the region Tuesday night with better chance of showers and thunderstorms across the area. CAPE will drop due to the loss of daytime heating but lift and shear increase ahead of the front. Strong to marginally severe thunderstorms will be possible once again. The steering flow should be quick enough to mitigate chances of flash flooding, but with high moisture content around, minor nuisance urbanized flooding is possible. There is a high risk of rip currents at all atlantic ocean beaches on Tuesday. Long term Wednesday through Monday The cold front will slowly push east of the area on Wednesday with lingering showers and perhaps a few embedded tstms mainly across the eastern half of long island and southern ct. Skies clear Wed evening with a much cooler airmass arriving. Canadian high pressure builds into the region Thursday through early next week, providing dry and sunny conditions. Temperatures will remain below normal as highs only reach the 70s to near 80 each day. There could be some isold showers tstms on Sunday as an upper trough moves through the northeast. Most model guidance has the upper level energy passing to the north of the CWA so have not included in the current forecast, however this may change in subsequent forecasts. Aviation 00z Tuesday through Saturday MainlyVFR through the TAF period. An isolated shower or tstm is possible early tonight from the nyc metros north west. Bigger forecast problem centers around late night reductions in cigs vsby. Think kisp kgon kswf most likely to see reductions to at least MVFR, but cannot totally rule it out at the the nyc metros some time between 09z-12z give or take an hour. South to southwest winds diminish tonight, and slowly increase tue morning. Then expect both stronger southerly coastal sea breezes and SW inland flow Tuesday afternoon, with gusts AOA 20 kt likely.
