.LONG TERM /FRIDAY THROUGH SUNDAY/...
Wetter and eventually cooler times on the way as we close out the
work week and head into next weekend.
Still appears at least the first half of Friday will be dry, and
possibly the entire day just depending on location of and speed at
which the deeper tropical moisture associated with TS Nicole moves
northward up the Atlantic Seaboard. The other player will be an area
of low pressure that moves NE`ward through the upper Great Lakes and
how its trailing cold front interacts with Nicole`s moisture. Timing
of these features will be key as there will likely be a swath of
heavy rain moving N`ward with this system. At this point, appears
the best chance for any significant rain will be from
central/eastern NY and points east Friday night into Saturday before
strong cold front sweeps it off the New England coast.
Now for the `cooler` portion of the forecast period. Much cooler air
will start to work in across the area through the day on Saturday in
the wake of the cold fropa and as a broad mid and upper level trough
takes shape over the central and eastern CONUS. Cold air will
continue to deepen through the second half of the weekend which will
lead to the development of lake effect rain showers as early as
Saturday afternoon, with the airmass growing cold enough to support
frozen precipitation all the way to the surface by Saturday night.
Big picture...lake effect rain and snow showers look like a pretty
good bet downwind of the lakes for Saturday night into Sunday,
although way to far out to pinpoint location. Several mid level
disturbances will also move through the trough aloft, so winds will
likely shift around a bit from time to time as well. Looking further
out, appears that overall this cooler pattern may have some staying
power, hence more seasonable weather may be here to stay for at
least a little while.
