AREA FORECAST DISCUSSION
National Weather Service Jackson KY
352 AM EST Fri Dec 2 2016

.SHORT TERM...(Today through Saturday)
Issued at 352 AM EST FRI DEC 2 2016

A stacked low pressure system across Quebec will continue to result
in cyclonic flow into the Ohio Valley, producing rounds of clouds
moving across eastern Kentucky. Despite the greatest concentration
of stratocumulus remaining north of the Interstate 64 corridor,
cirrus will stream in downstream of an upper ridge attempting to
build north across the Great Plains as an upper low digs into the
Gulf of California. However, aforementioned Canadian upper low
will limit height rises, subsequently keeping high temperatures in
the mid 40s to low 50s as a low level cold dome remains locked in
place into the Tennessee Valley. Surface ridging stretching from
the northern plains to the northern gulf coast will make greater
headway toward the Commonwealth today. Enough of a pressure
gradient will remain in place to allow for west/southwest winds to
still increase to 5-10 mph later this morning through this
afternoon.

This surface ridge looks to nose into southern Kentucky this evening
and tonight, producing calm surface winds. Portions of the Big Sandy
region through northeast Kentucky will likely see enough low level
moisture to keep radiational cooling from taking full effect. The
remainder of eastern Kentucky will likely also be somewhat limited
in this regard as the cirrus shield thickens and becomes more
widespread. Nonetheless, valley locations should cool into the mid
20s while ridges remain near 30 degrees by daybreak Saturday.

Upper ridging looks to finally move overhead by later in the day on
Saturday with accompanying height rises. However, top-down
moistening and high pressure overhead, making for slow retreat of
the lingering cold dome, will in all likelihood result in below
normal temperatures once again to start the weekend, as highs top
out in the mid 40s to low 50s.

.LONG TERM...(Saturday night through Thursday)
Issued at 352 AM EST FRI DEC 2 2016

The Long Term Discussion will be issued shortly.

.AVIATION...(For the 06Z TAFS through 06Z Friday night)
ISSUED AT 1253 AM EST FRI DEC 2 2016

Greatest concentration of cloud cover continues to remain north of
Interstate 64, with only isolated to scattered clouds off to the
south. Thus, VFR conditions look to remain in place with some
stratus/stratocumulus around FL035-040 and some high cirrus.
West/southwest winds will be light at less than 5 mph overnight
before increasing to 5-10 knots Friday morning. These will
diminish late Friday afternoon as they veer to the west/northwest.
While a few clouds will remain around FL030 Friday evening/night,
ceilings currently look to remain northeast of all sites.
