.SYNOPSIS...
High pressure at the surface and aloft will generally dominate
the regions weather through at least Wednesday with dry
conditions and warming temperatures expected. A weak disturbance
passing through aloft on Sunday will provide cloudier skies and
perhaps some sprinkles, but overall the next chance for any
appreciable rainfall 
isn`t until Thursday.

.NEAR TERM /THROUGH MONDAY/...  
-- Changed Discussion --
 
As of 1014 PM EDT Saturday...Temperatures have dropped sharply
following sunset with pretty ideal radiational cooling 
set up as
only some high thin clouds are in place with light to calm 
winds. Minimum temperatures overnight will bottom out in the
lower 40s to lower 50s, coldest in the Adirondacks and Northeast
Kingdom. Previous discussion follows.

A strong mid/ upper level 
 ridge 
will center over the Northeast
tonight continuing dry weather across the region. High clouds 
will be on the increase though ahead of a moisture 
starved shortwave 
 trough 
which will track through the region Sunday
afternoon and night, providing mainly just an increase in cloud
cover, and perhaps a 10% chance for a sprinkle or very light
shower across the Adirondacks. Otherwise, variable temperatures
are expected again for the overnight hours the next 2 nights,
with lows ranging from the mid 40s to mid 50s tonight, and
through the 50s Sunday night. Temps Sunday could warm a couple
of degrees warmer than today, though with thicker mid/high
clouds feel it will be about the same as today with highs in the
upper 70 to low 80s.

.SHORT TERM /MONDAY NIGHT/...
As of 315 PM EDT Saturday...Heat continues to be the primary
focus early next week with afternoon highs in the low/mid 80s
outside of higher terrain. Mainly dry conditions will be
expected as ridging amplifies over the North Country. A few very isolated 
showers will be possible over far northeastern Vermont
as a trough 
swings around the western periphery of a stalled
upper over the Gulf of Maine. Overnight lows will be mild, but
will provide relief with dew point 
temperatures being lower than
usual.

&&

.LONG TERM /TUESDAY THROUGH FRIDAY/...
As of 315 PM EDT Saturday...Unseasonably warm temperatures are
strongly favored through Thursday with an omega 
high blocking
pattern likely 
persisting over the Northeast. Highs in the 80s
will be highly probable Tuesday and Wednesday while uncertainty
increases Thursday with models projecting a large trough 
to move
towards the Northeast. The biggest question remains whether or
not the next projected trough 
will be able to move into the
North Country by late Wednesday/Thursday, or if it will be held
back by the strong ridge 
resulting in a delay until Thursday
night/early Friday for increases in shower chances. Models have
a known bias with moving blocking patterns too quickly. Also,
this high has been quite dry, so it should take a little longer
to saturate the column to get rain to the ground. As such,
30-50% chances of showers were maintained through Thursday
before increasing chances above 50% by Friday when a secondary
wave would likely 
have more success into moving farther east.
Once showers do move in, temperatures will likely 
drop into the
70s, but unlikely to be lower since flow 
will remain
southwesterly. Heading into the next weekend, ensembles 
favor a
longwave trough 
over the region with the upper low stalling and
supporting continued shower chances.
