points.

previous discussion
Low pressure at the surface and aloft will remain north of the
state through tonight. Drier air will gradually overspread the
forecast area today in the wake of the passage of the cold
front. Expect skies to become partly to mostly sunny by
afternoon. Dew point temperatures will fall from the mid to
upper 60s early this morning and into the 50s by this afternoon.
It won`t be quite as warm this afternoon as it was yesterday
but still a few degrees above normals for this time of year,
with highs in the mid to upper 70s north and upper 70s to near
80 down east. West winds will gust to around 25 mph at times
this afternoon.

Low pressure to our north will continue to weaken as it moves
northeast away from the region tonight and surface high
pressure builds in from the west. Expect partly cloudy to
mainly clear skies across the region. Lows tonight will range
from the upper 40s to lower 50s north and low to mid 50s
central and down east.

.SHORT TERM /THURSDAY NIGHT THROUGH FRIDAY NIGHT/...
Thu will begin fair...drier and cooler to start with increasing
sc cld cvr msly across the N in the aftn with isold shwrs
possible across the far NW as a weak s/wv trof alf crosses the
Rgn from QB. Any shwrs will dissipate by erly Thu eve with the
loss of day tm htg, leaving fair skies, lgt winds and
radiational cooling late Thu ngt for chilly ovrngt lows spcly
across Nrn vlys.

Fri will again begin fair with increasing cldnss in the aftn
along with isold to sct cvrg of shwrs across the N as a more sig
s/wv trof alf crosses the Rgn from Cntrl QB. These shwrs also
will dissipate erly Fri eve as day tm htg is lossed. Hi temps
Fri will likely be a few deg cooler than Thu followed by another
cool ngt late Fri ngt as skies clear with lgt winds...promoting
some radiational cooling.

.LONG TERM /SATURDAY THROUGH TUESDAY/...
The long term will begin with below avg temps for Sat with a
slow warming trend beginning Sun and cont into erly next week.
Cannot rule out isold shwrs across the N durg the day Sat with
some left ovr upper troffiness indicated by long range models,
otherwise, Sun thru Tues looks to be completely rain free as any
weak upper low/trof moves E of our Rgn into the Can Maritimes
