.AVIATION...27/00Z TAF Cycle

Scattered SHRA and a few TSRA are ongoing across the fcst region
with widespread low- to mid-level cloud cover. Conditions will
continue to remain at MVFR/IFR clgs and vis, with mostly SHRA
persisting over Cntrl/Ern AR through the remainder of Mon night
into early Tues. A cold front will enter from the NW around
27/03Z, bringing a sharp wind shift from Srly to Wrly with
sustained winds of 20 kts expected, and stronger gusts possible.
Additionally, have included WS groups at all terminals through
27/04Z. As the front moves across the state late in the period,
an upward trend in conditions towards VFR is expected with
clearing skies and modest W/Nwrly winds.

.PREV DISCUSSION...(ISSUED 247 PM CST Tue Nov 26 2019)
Short Term...Tonight thru Thanksgiving Day...
The event we have been discussing for several days is now upon us.
Trof coming across the Rockies has spun up a vigorous surface low
across the Plains, which is making for a tight pressure gradient in
its vicinity. A surface cold front is making its way toward the
state, and will push thru the area overnight.

Considerable wind shear is present across the forecast area, with
relatively little instability in most areas. Surface-based CAPE is
virtually non-existent, but there are some pockets of elevated CAPE,
by my estimate there could be a few areas where the elevated CAPE
exceedes 500 j/kg. It should be noted that plenty of light rain and
drizzle has been falling across portions of the state today, and
some heavier rainfall bands are starting to show up across the
northwestern portions of the state, which is in line with what most
of the meso models have been showing today.

At the moment the convection is quite shallow, which is not
unexpected given the current thermodynamic profile. With midlevel
winds potentially exceeding 100 knots (especially across the north),
it's not hard to envision a weaker storm producing wind damage if
even a portion of that wind energy is able to translate to the
surface. As for the tornado threat, I could see a few weak tornadoes
spinning up later this evening into tonight in a QLCS-type event,
and these will be quite challenging to detect.

The front should push rapidly thru the state tonight, bringing
cooler and drier air to the state for tomorrow. Of course
Thanksgiving is looking to be wet, as a strong trof across the west
coast sets up a southwesterly flow aloft, with numerous shortwaves
moving thru the flow across the area.

Extended Term...Thursday Night thru Tuesday...
The long term period will begin with an upper level ridge axis just
east of the state, bringing southwesterly flow aloft to Arkansas.
With plenty of upper level moisture, disturbances in the flow will
develop widespread precipitation over the western and northern parts
of the state Thursday evening through Friday evening. Surface flow
will be southerly as well, bringing warm, moist air through the area
along with the precipitation. Highs Friday will be in the mid 50s to
mid 60s through the state, lows in the mid 40s to upper 50s.
We'll warm up to the mid 60s to lower 70s Saturday afternoon.

A cold front will move east through the state Saturday, as an upper
low tracks east through the northern plains region, aiding in more
organized and widespread precipitation across the central and
southern plains, covering the state by Saturday morning. The rain
will exit Sunday morning as the upper low exits to the east and an
upper level ridge builds into the region behind it, along with cold,
dry conditions. Temperatures Saturday night in the mid 30s in
northern Arkansas to the lower 40s in the southern part of the
state. Temperatures will cool into the early part of the week, with
highs in the 40s and 50s. Low temperatures will be in the upper 20s
to lower 30s Monday and Tuesday morning.

gusty winds as these storms will be moving very quickly. While
the tornado chance is low, it can not be ignored.
