Great Lakes region and southern Ontario, as front pushes into
the Mid-Atlantic and SE US. Dampening shortwave energy
associated with this feature could be enough to support isolated
to widely scattered showers and storms overnight. High res
models show line of precip associated with this feature having a
difficult time pushing east of the mountains, but models are in
good agreement showing weakening line approaching the coastal
plain after 03/04z. Will continue sc/low chance pops, with best
chances across the northern tier late. Overnight lows in the
upper 60s/low 70s.
.LONG TERM /FRIDAY THROUGH WEDNESDAY/...

this evening, with seas building to 4-7 feet south of Oregon
Inlet. Will initialize with SCA for the central waters with
41025 still hovering at 6 ft, and NWPS model keeps 6 ft seas
across the central waters through the period. SCA seas develop
south of Ocracoke this evening.
Long Term /Fri through Mon/...
As of 230 AM Thu...Moderate SW flow of 10 to 20 kts expected
thru Sat night around offshore high pres. These winds combined
