AREA FORECAST DISCUSSION
National Weather Service Jackson KY
529 PM EDT Sun Sep 4 2022

.SHORT TERM...(This evening through Monday night)
Issued at 529 PM EDT SUN SEP 4 2022

Little has changed since yesterday. Late this afternoon a large,
weak, slow moving upper level trough extends from eastern TX to
the Great Lakes, where it meets up with a more progressive trough
in the prevailing westerlies aloft. Upper level ridging is off
the southeast coast. In between, our flow is from the southwest
over a very long fetch, bringing deep tropical moisture over the
region. At the surface, a high pressure ridge remains near the
East Coast. Flow around the west side of the surface ridge is
bringing warm and humid air northward across the region. The flow
continues to have a downslope component in the JKL forecast area,
especially the eastern counties. However, the flow is very weak,
and the drying influence is minimal. The setup is producing
showers and thunderstorms, especially since diurnal
destabilization occurred. Models show precipitable water generally
from 1.75-2 inches.

This scenario will change very little through Monday evening.
Features focusing convection are very weak and difficult to pin
down. Areas of showers and thunderstorms will likely persist into
this evening, but eventually show diminishing coverage as heating
is lost. The GFS and the HRRR indicate another uptick in activity
toward dawn, with the NAM following suit during Monday morning.
Have followed this general trend in the forecast. If this is the
case, it could keep activity later in the day Monday somewhat
more limited by inhibiting heating. However, confidence is not
very high in the evolution. With weak flow, high atmospheric
moisture content, and forecast soundings showing thin CAPE in the
column, conditions favor heavy rainfall. However, very weak
features, weak inflow, and lack of organization would probably
keep any hydro problems fairly localized. A Flood Watch into
Monday evening was inherited and let it ride to cover this threat.

The upper level trough will continue to slowly advance, especially
on the northern end as it gets dragged along by the more
progressive trough in the prevailing westerlies. By the end of
Monday night, this will make our flow aloft a bit more zonal, and
the highest precipitable water is expected to shift eastward. Weak
surface low pressure is expected to develop east of the
Appalachians Monday night, and this will result in very little low
level flow in our area. The combination of factors should reduce
our heavy rain threat.

.LONG TERM...(Tuesday through Sunday)
Issued at 335 PM EDT SUN SEP 4 2022

A very active weather pattern is anticipated in the extended, as
a series of upper level troughs, sluggish surface fronts, and
perhaps a closed low all make their way through the region. The
most active periods will be during the afternoon and early evening
hours from Tuesday on into the upcoming weekend. Persistent and
at times widespread cloud cover, along with repeated rounds of
rainfall, will keep temperatures below normal each day. Daytime
highs in the upper 70s to lower 80s are on tap because of this.
Nightly should bottom out in the mid 60s on average. Winds will be
either out of the light and out of south or light and variable
during the period.

&&

.AVIATION...(For the 18Z TAFS through 18Z Monday afternoon)
ISSUED AT 234 PM EDT SUN SEP 4 2022

Mainly VFR conditions were present to start the period, but
ceilings were common. Spotty showers/thunderstorms were beginning
to develop around the area. They will increase in coverage,
peaking during the late afternoon or early evening, and will bring
localized IFR or worse conditions. However, timing/location is too
problematic to include anything more than VCTS in TAFs. The
activity should diminish after about 00Z. Another increase in
showers is forecast around dawn, with most places expecting rain on
Monday morning. This will probably lead to VLIFR conditions,
except for extreme eastern KY, where downslope low level flow may
provide enough drying influence to spare that area and allow VFR
conditions to persist.
