National Weather Service New York NY
252 PM EDT Sun Oct 1 2023
.SYNOPSIS...
Offshore low pressure will continue to track out into the
western Atlantic, while high pressure builds in through mid
week. The high will then give way to a frontal system at the
end of the week.
&&
.NEAR TERM /UNTIL 6 PM THIS EVENING/...
Forecast remains on track this afternoon. High pressure will
continue to provide dry conditions. today. Will continue to
carry haze in the forecast as the northerly winds usher in smoke
from the Canadian wildfires. Otherwise it will remain cloud
free.
Highs this afternoon will be in the 70s.
&&
.SHORT TERM /6 PM THIS EVENING THROUGH TUESDAY/...
Not much change during this time as temperatures work upward
heading into Tuesday. Highs on Tuesday will be around 80 for
many locations, with the 70s elsewhere. These readings will be
about 7 to 10 degrees above normal. Overnight lows will be mild
as well, from the 50s to around 60. Locations that typically
radiate well may get closer to around 50. Winds will also be
light during this time as the high builds across the area.
Seabreezes are likely in the afternoon.
&&
.LONG TERM /TUESDAY NIGHT THROUGH SATURDAY/...
Deep layered ridging over the Northeast will promote an extended
period of dry weather through the mid week period. It will
remain dry with above normal temperatures.
A 500 mb trough then digs into the Great Lakes Region on
Friday. This will help push a cold front through the forecast
area at some point Friday night into Saturday. The global models
over the last 24h have trended to a more amplified system, even
hinting a the the upper trough taking on a negative tilt. Still
though, it`s much too early to be too specific with the timing,
but there remains a chance of showers across the area starting
on Friday, with higher overall chances Friday night and Saturday
as the frontal system moves into the areas. Highs both days
will be cooler and closer to normal.
