After this, the remnants of Ida will track across the mid-Atlantic
states around Wednesday. Model guidance continues to show strong
high pressure to our north will keep the tropical remnants to the
south of the forecast area, but there will be a very sharp gradient
with significant rainfall possible just south of the NY/PA state
line. There`s little doubt that most of the area will remain rain-
free, with a small chance the Western Southern Tier will get clipped
by some rain Wednesday. Otherwise, there will be a cool
northeasterly flow due to the pressure gradient between the strong
high pressure system and the remnant low passing to our south and
east. High temperatures will only range from the upper 60s to lower
70s on Wednesday.

.LONG TERM /WEDNESDAY THROUGH SUNDAY/...
An upper level trough across New England on Thursday will slide
east with a ridge building across the lower Great Lakes through
Friday. Meanwhile, surface high pressure will drift east across
the area which will provide a continuation of dry weather. It
will be cooler, but generally comfortable, with highs ranging
from the upper 60s to mid 70s Thursday and Friday.
Over the weekend, a shortwave will dig across Ontario province with
a series of weak frontal boundaries potentially crossing the region.
There`s some model disagreement if there will be a warm frontal
passage ahead of a cold front or just a cold front. Either way,
Saturday should be mainly rain-free with just a small chance for
showers Saturday night and Sunday. It will be slightly warmer, with
highs in the 70s over the weekend. There`s some potential it could
be 5 degrees warmer (or cooler) than forecast depending on the
progression of the warm front.
