.DISCUSSION...
.KEY MESSAGE 1...

A nearly zonal flow aloft today will be followed by significant
height rises along the eastern seaboard Sunday through Tuesday.
By Monday night, 500mb height anomalies will be on the order of
2 to 3 standard deviations above normal. What this all means is
much warmer weather this weekend, but the hottest days are forecast
to be Tuesday and Wednesday. For these days, temperatures will
be about 15 to 25 degrees above normal. Highs will get into the
upper 80s to as high as 95 away from the immediate coast. The
warmest readings will be north and west of NYC and interior
southern CT. Gusty SW-S winds both of these days will bring in
cooler maritime air in along the coast, especially across the
south shore of LI.

Highs Sunday will be in the 80s and possibly 90 Sunday for the
warmest spots. Even coastal areas are anticipated to be into the
upper 70s to low 80s.

Monday poses a bit of an anomaly during this period, as a backdoor
cold front passing through the area Sunday night will lead to more
of a marine influence with SE winds. Many locations will see highs
fall off 5 to 10 degrees with the possible exception being locations
well north and west of NYC. A passing shortwave trough and strengthening
confluent flow across eastern Canada and into the Northeast Sunday
night look to be just enough to get the front as far NE NJ and
eastern portions of the Lower Hudson Valley. The front quickly
returns to the north as a warm front Monday night. The S/SW flow
in the warm sector Tuesday and Wednesday will bring the hottest
days as previously mentioned. Heat index values could approach
95 in spots away from the coast.

NBM high temperatures were blended with the NBM 10th percentile and
the CONSAll to knock down highs some based on a noted warm bias
early in the warm season.

Expect mainly dry conditions with an isolated shower and/or sprinkle
tonight with the passage of shortwave trough. There could also be an
isolated late day thunderstorm north and west of NYC Monday and
Tuesday afternoon/evening.

.KEY MESSAGE 2...
A positively tilted upper trough builds in from the NW mid to late
week sending a cold front across the area Wednesday night into
Thursday. The boundary looks to be active with scattered to numerous
showers and thunderstorms. More seasonable temperatures are forecast
for the end of the week. NBM does maintain a slight chance of showers
as there are some differences in the progression of the system.
More recent model guidance suggests that the the cold front pushes
far enough south to allow for a slightly warmer and drier Thursday
than previous runs.

.KEY MESSAGE 3...
There are cold water safety concerns this weekend as water
temperatures remain in the lower 50s. The cold water temperatures
can quickly cause hypothermia and physical incapacitation to anyone
suddenly immersed in the water. Anyone going out on small boats,
canoes or kayaks should plan accordingly and use extreme caution to
avoid this threat.

.MARINE...
A SCA remains in effect for the oceans through Sunday.

A strengthening southerly flow brings a return to SCA
conditions on the ocean through Sunday. Winds will gradually
subside tonight into tomorrow. However, ocean seas could linger
around 5 ft for much of Sunday with residual S swell.

There are cold water safety concerns this weekend as water
temperatures remain in the lower 50s. The cold water temperatures
can quickly cause hypothermia and physical incapacitation to anyone
suddenly immersed in the water. Anyone going out on small boats,
canoes or kayaks should plan accordingly and use extreme caution to
avoid this threat.

Sub-SCA conditions are anticipated Sunday night through Monday night
as flow temporarily weakens under high pressure. SCA conditions
likely redevelop on the ocean water Tue into Tue night with
strengthening SW flow, potentially for all waters by Wednesday.
