...AVIATION UPDATE...

.KEY MESSAGES...

- A potent storm system will impact the region today before
  departing to the east late this evening. Showers and a few
  thunderstorms along with gusty wind will be the main impacts.

- Widespread hazardous weather is not anticipated; however,
  locally heavy rain and an isolated strong to severe
  thunderstorm will be possible late this morning and early
  afternoon, mainly east and southeast of a Trigg to Caldwell
  and McLean county line in western Kentucky. The main threat
  from the storms will be damaging winds; however, an isolated
  spin up tornado will also be possible.

- Behind the system, an extended period of dry weather is
  expected through much of the week. Temperatures will be chilly
  Sunday and Monday before gradually moderating through rest of
  the week.

.DISCUSSION...
Issued at 259 AM CST Sat Dec 9 2023

The main period of concern for this forecast issuance will today
into early this evening. A surface low pressure system over northern
Missouri is expected to continue lifting northeastward to northern
Lake Michigan by 15Z today. This low is expected to deepen as an
upper-level low digs southeastward through the northern Plains into
the western Great Lakes. A cold front extends south and
southwestward from the low this morning, stretching from just west
of St. Louis to just east of Springfield MO into southwest Arkansas
as of around 08Z this morning. This is fairly easy to identify with
cloud cover along the boundary, a quick drop in temperatures from
the 60s east of the boundary to the low to mid 40s west of the
boundary. Winds also shift from the south to the west and northwest
on the back side of the boundary. This will act as the main focus
for showers and storms as the cold front shifts east through the
area this morning into early this afternoon.

Instability values are progged to be around 400-600 J/kg over mainly
the Pennyrile up toward southwest IN between 15Z and 21Z, which is
largely a result of moisture lift rapidly northward ahead of the
frontal boundary. While this isn't a lot of instability, it really
doesn't take much with shear values on the order of 40 to 50 kts
from the southwest. A small portion of this will be perpendicular to
the forcing, so there could be some organization if the shear and
instability values are realized. (Instability is probably the
main limiting factor with respect to severe potential) The main
threat will be damaging wind gusts with a strong mid-level jet
set to be in place as the convection traverses the area. It
isn't completely out of the question that an isolated tornado
could quickly spin up mainly east of a line from around Trigg to
Hopkins and McLean Counties as 0- 3 km shear values are progged
to be between 30-40 kts from the west to west- southwest. This
is pretty much in line with the SPC slight risk area that
brushes through the eastern portion of the CWA. Not a high
confidence scenario, but definitely worth keeping an eye on for
evolution this morning/early afternoon.

There is a marginal risk for excessive rainfall for mainly western
KY into southwest IN; however, it does appear that the convection
will be moving fast enough to keep the overall threat fairly
limited. There will still be some very heavy downpours associated
with convection. The heaviest rainfall totals have also shifted to
the east with the latest update with western KY into southwest IN
seeing between a half inch and an inch of rain, while much of the
rest of the area will see around a quarter inch of rain.
Temperatures will likely max out by mid morning and then drop
quickly as the front passes from the west/northwest.

The bulk of the system/moisture will depart to the east of the area
by Sunday morning with the upper trough axis swinging through by
early afternoon. This will set the stage for continued troughing
through the day Monday. Temperatures will cool below normal to start
the week with highs in the low to mid 40s and lows in the 20s to
around 30! Zonal to somewhat troughed flow will linger through the
middle of the week as temperatures begin to moderate. A lack of an
influx of moisture will keep mainly dry conditions in place! The
pattern looks set to shift to a warmer pattern for the end of next
week as upper ridging builds in once again!

.AVIATION /18Z TAFS THROUGH 18Z SUNDAY/...
Issued at 1129 AM CST Sat Dec 9 2023

A potent cold front is moving through the area today and
bringing storms with it. Showers and thunderstorms are possible
at most of the TAF sites through this evening. Cigs will likely
remain MVFR though visibilities could be reduced at times down
to IFR under heavier rainfall. clouds should start to clear out
behind the front though there looks to be some lingering
midlevel clouds overnight. Winds will switch around to the north
behind the front and will remain around the 10 kt range.
