.DISCUSSION...
.KEY MESSAGE 1...
Surface high pressure builds east and settles offshore into
Friday. This will allow drier conditions to persist with a
gradual warm up.

More sunshine is expected today compared to Tuesday, but still
anticipate sct stratocu to develop in the afternoon with a
cirrus deck moving in late. A weak warm front lifts up to the
northwest on Thursday leading to an increase in high and mid
cloud cover, but expect conditions to remain dry. Temperatures
get into the 70s both days, with Thursday several degrees warmer
than today.

By Friday, deep SW flow helps pump H925 temps toward 22-23C.
Forecast highs are into the low 80s for most areas, perhaps mid
80s in urban NE NJ, about 10 degrees over climo for early
October but far from record territory. A cold frontal passage
late Friday brings an end to the warmth. A few showers are
possible with the front Friday evening, mainly across the north
and west interior, but coverage and impacts appear limited.


.KEY MESSAGE 2...
Behind the frontal passage, surface high pressure quickly
builds east from the Great Lakes, ushering in a cooler air mass
for the weekend.

With cool, dry northerly flow, temperatures Saturday likely
struggle to reach 70 in most areas. Winds veer E by Sunday as
the high shifts into New England.

Forecast confidence then lowers a bit by late in the weekend
with uncertainty around a possible wave of low pressure that
could develop and pass to the south. Global NWP and AI guidance
has generally backed away from wetter solutions previously
offered, but being 4 to 5 days out, will still need to monitor.
For now, went with the national blend`s 20 to 30% chance for
showers Sunday and Sunday night. Otherwise, remaining cooler in
the 60s with high pressure once again building in from the Great
Lakes into early next week.

.MARINE...
Light SW flow continues through Thursday with high pressure
settling offshore. Winds and seas increase with an approaching
cold front Friday and this could lead to a brief period of SCA
conditions on some of the coastal ocean waters by Friday evening.

Behind the fropa, winds turn N on Saturday, then E by Sunday,
but conditions are expected to remain below SCA criteria through
the weekend.
