.SYNOPSIS...
High pressure will build in from central Canada through Friday as an
upper level trough swings through eastern Canada. High pressure will
crest over the area this weekend into early next week.

&&

.NEAR TERM /THROUGH TONIGHT/...
All in all, a pretty quiet wx pattern for tdy thru tngt. Skies
will begin mclr this morn, with a build up of some sc cld cvr
this aftn across the N hlf of the FA as a weakening s/wv trof
alf crosses the Rgn from Cntrl QB. SC cld cvr will dissipate
across the Rgn erly this eve with the loss of day tm htg,
leaving mclr skies for the ovrngt. Hi temps tdy and lows tngt
will cont a slow cooling trend...about 5 deg cooler than ystdy.

&&

.SHORT TERM /FRIDAY THROUGH SATURDAY/...
A large area of high pressure building in from central Canada
combined with a cool upper level trough moving over the region will
bring a cool day on Friday. Stratocumlus clouds forming in the cool
mid level air will likely spread into northwestern areas Friday
morning then across the rest of the north Friday afternoon. A few
spotty showers are possible across the north Friday midday and
afternoon. Temperatures will only be in the 60s north and the low
70s Downeast on Friday. Skies will be partly cloudy north and
clear Downeast Friday night with a cool and dry night. This will
give way to a cool day on Saturday with high pressure
continuing to build down from the northwest, and a mixture of
sunshine and cumulus clouds.

&&

.LONG TERM /SATURDAY NIGHT THROUGH WEDNESDAY/...
A large and slow moving high pressure system across the area will
bring clear and dry weather Sunday into early next week. During the
mid-week period our focus will be on a subtropical low spinning off
the Southeast coast. Models have been varying considerably on the
track of this low. The ECMWF carries it out to sea, and the latest
GFS is now also carrying the low south of the area on Wednesday and
out to sea. If this is the case, dry weather will persist through
midweek with some spotty showers possible Thursday as a weak front
drops down from the north. The next chance for significant
precipitation may be from the remains of tropical storm Harvey
lifting across the east late next weekend.

&&
