.DISCUSSION...
KEY MESSAGE 1...A drier airmass spreads into the region this
afternoon.

In the wake of a cold front that is passing offshore this
afternoon, a drier airmass continues to spread into the region
with surface dewpoints dropping from the upper 60s to around 70
to the low 60. Can`t fully rule out a spot shower or two with
broad upper level troughing overhead, particularly across
northern NJ and the Poconos, but it will remain largely dry for
the rest of the afternoon as high pressure builds in from the
west.


KEY MESSAGE 2...Fair weather is expected to return later Sunday
and should persist into the middle of the upcoming week.

More zonal flow with some subtle ridging moves in for the first
half of the week. At the surface, high pressure will mainly be
in control, resulting in dry and tranquil weather through
Wednesday. Temperatures should be seasonable through this
stretch.

KEY MESSAGE 3...More unsettled to end the week.

By Thursday and Friday, high pressure moves offshore with
southerly return flow, helping bring dew points back into the
low-70s. Broad upper level troughing will allow a surface low to
make its way into the region, bringing our next chance for
precipitation. Still a bit far out for specifics at this time,
however.
