.DISCUSSION...
.KEY MESSAGE 1...
Good radiational cooling tngt with high pres building over the
area. The 12Z MET and MAV were blended in with the official
fcst. The NBM continues to look too warm under these conditions.

No changes to the frost advy with the nrn tier the best chance
to see widespread frost.

.KEY MESSAGE 2...
Dry and mild thru most of the week with return flow around the
departing high. A cold frontal passage could produce a few shwrs
late Wed ngt and Thu, but the sys is moisture starved and the
NBM pops are dry. Kept the fcst dry as a result.

The warmest day is Thu attm right ahead of the front. The
numbers however will depend on the speed of the front. The NAM
is much quicker, and would keep temps cooler as a result. The
MET has 69 for a high at EWR. In contrast, the slower GFS
supports of high of 80 in the same place per the MAV. Stuck with
the NBM which was middle of the road for now.

.KEY MESSAGE 3...
The next chance for rain is Sunday night into the beginning of
next week as residual tropical moisture potentially gets into
the area ahead of the next upr trof. Too far out to deviate from
the blended approach with chances now in the 40-50 percent
range. There is the possibility that the upr trof gets in quick
enough to keep most of the moisture south of the area with
little pcpn. There is also the possibility that the tropical
moisture gets into the area and produces some locally heavy rain
before the trof clears things out.
