.SYNOPSIS...
High pressure remains in control through midweek. Cold front
to bring cooler temperatures but limited precipitation Thurday.
Another weak system by the weekend.

&&

.NEAR TERM /THROUGH TUESDAY/...
As of 130 PM Monday...

High pressure dominates the weather the start the week. This
will bring dry conditions with daytime highs well above normal.
High clouds, thanks to Hurricane Maria will linger during this
time. Morning river valley fog will be the only real weather
concern.

&&

.SHORT TERM /TUESDAY NIGHT THROUGH THURSDAY/...
As of 300 PM Monday...

Temperatures will remain well above normal for this time of year
to start the period as the responsible upper-level ridge erodes
with an approaching trough from the West.

Autumn knocks on the door with great anticipation Wednesday
night through Thursday with a mainly-dry cold front moving
through the region from the NW to SE. Hurricane Maria will
continue to hang around the coast of North Carolina, and its
circulation effectively cuts the moisture feed into this area.
Pressure fields will be somewhat compressed in the eastern zones
due to Maria, so some gusts in 10-15 mph neighborhood can be
expected. What little low-level moisture exists will turn to
scattered cumulus cover in the cold-air advection behind the
front during the day Thursday with near-normal temperatures.

&&

.LONG TERM /THURSDAY NIGHT THROUGH MONDAY/...
As of 300 PM Monday...

A progressive weather pattern dominates the long-term forecast.
A reinforcing shot of cold air behind another mainly-dry cold
front will sweep though Friday night into Saturday, with low-
level Great Lakes moisture struggling to make much headway into
this area. Long-range model consistency tapers off considerably
going into the next week with indications of generally
unsettled weather.

&&

.AVIATION /19Z MONDAY THROUGH SATURDAY/...
As of 130 PM Monday...
VFR will continue through the daytime hours into the early
evening hours. River valley fog will develop once again. LIFR
conditions are anticipated in this region. By sunrise, fog will
lift. By mid morning, conditions will return to VFR.
