.DISCUSSION...
.KEY MESSAGE 1...
A weak frontal system tracking east of the Great Lakes today,
and then across the region tonight into Wednesday will bring a
warm front through the region late tonight into Wednesday, and
be accompanied with showers. The system is a little slower and
today will be dry. With weak forcing along the warm front
showers will become late tonight into Wednesday morning, and
CAM`s and NAM are showing widespread precipitation, so
increased probabilities to likely. Warm advection and the
frontal passage ill bring milder air into the area with
temperatures nearing normal levels tonight into Wednesday.
Thursday is likely the mildest day of the week with highs in the
upper 60s/lower 70s from NYC north/west, and lower/mid 60s east
as weak upper ridging builds behind the low.


.KEY MESSAGE 2...
Not much change for the weekend from the earlier forecast.
Upper air pattern heading into the weekend will a feature a
weakening upper ridge just west of the area, sandwiched between
an upper low over the Northern Plains and another east of New
England and the Canadian Maritimes. At the same time, a surface
high builds over the area on Friday, following what appears to
be a back door cold front. A warm front associated with the
western system then moves nearby on Saturday. This results in a
strengthening boundary in close proximity to the area. This will
be a key player in determining the coverage and extent of rain
this weekend.

The 00Z operational global models still indicate that the
surface ridge could be strong enough to keep eastern areas, in
particular eastern Long Island and southeast CT on the drier
side, with higher probabilities of rain back toward NYC and
northern NJ. The latest ECMWF has trended just a bit drier for
the area, but still one of the wetter solutions. Either way, it
looks like there will be a tight gradient somewhere close to the
area, going from rain to no rain. Also, there is decent
agreement in a persistent easterly flow which will keep high
temperatures in the 50s both days, especially for eastern and
coastal areas. Using the NBM, this results in cloudy conditions
with a chance of rain everywhere Saturday and likely Pops for
NYC north and west, but decreasing on Sunday as a frontal wave
and boundary get suppressed to the south by strengthening
high pressure.

.AVIATION /15Z TUESDAY THROUGH SATURDAY/...
High pressure along the Mid Atlantic coast will shift offshore
today, with a frontal system approaching the area late tonight.

period of 20-25 kt gusts for some coastal terminals late tonight
into early Wed morning.
