.SHORT TERM /6 PM THIS EVENING THROUGH FRIDAY NIGHT/... The main weather hazards with the strong cold front will be strong winds with gusts up to near 65 mph, possible flooding, both from heavy rain and coastal flooding. Winds will continue to increase in the low levels of the atmosphere Thursday night along with the rain. The rain will become more widespread and will become heavy. Vertical forcing is shown with Q Vector convergence in the 850 to 500 mb layer. PWATS with all the increasing southerly flow will rise near 1.5 to 1.6 inches by early Friday morning, which is above the maximum moving average climatology for OKX according to SPC sounding climatology. Model soundings show warm cloud depth 10-11 kft. Despite the lack on instability, still a lot of dynamic forcing and anomalous moisture so flooding will be a possibility including flash flooding. With the strong SE flow, that should enhance rainfall amounts for the higher terrain north and west of NYC with orographic lift. Those locations could end up being on the higher side of total rainfall amounts. See hydrology section for more details and for the coastal flooding see the tides/coastal flooding section for more details. For the winds, there will be a low level jet strengthening through the night, with around 90-95 kt winds in the 850 to 900mb layer as a max near 7-11Z for NYC and locations north and west, SW CT, Central Long Island in the 8-12Z time period and 9-13Z to the east using the 3km NAM Bufkit. The NAM shows a stronger inversion so only a fraction of this jet will be mixed down, but with the downward momentum from the heavy rain, winds at 1500 ft could easily mix down and those are in the 50-60 kt range. The models have a consensus of a main cold frontal squall line that moves into the forecast region and then strengthens as it moves across Long Island and Southern Connecticut. With GFS Bufkit shows this as well but overall timing with the whole cold front and highest winds and rain is a few hours earlier compared to the NAM.- 227 replies

All the models are basically the same as far as timing and gust potential I guess it’s just comes down to the inversion now, upton thinks with the rain we should be able to mix down 50-60kt- 227 replies

Plus all the melting snow in the city, and hours of 40-50 gust will beat up trees. I live 4 blocks from the water and 10 min from Atlantic in Brooklyn south we usually take a beating in winds by me. But to counter all this isias and a severe t storm event we had did take down a lot of dead wood.- 227 replies
