AREA FORECAST DISCUSSION...UPDATED AVIATION
NATIONAL WEATHER SERVICE ST LOUIS MO
1150 PM CST THU DEC 24 2015
.SHORT TERM: (Through Late Tonight)
Issued at 342 PM CST Thu Dec 24 2015
Low-mid level WAA and MCON along with frontogenetic forcing resulted
in an elongated region of light rain earlier today across central
and northeast MO. This regime is occurring in advance of a low-
amplitude disturbance which is dampening and now located in western
MO. Overall forcing has diminished and shifted to the northeast of
the CWA and only a narrow elongated ribbon of light rain still
persists in west central IL. Present indications is this will also
diminish and shift to the northeast the remainder of the afternoon
and early evening as the disturbance aloft and associated surface
cold front push east. There are some indications in the HRRR and GFS
that a new narrow band of precipitation may try to develop this
evening somewhere in the SE/EC MO into SW IL region in response to a
new region of low level MCON. I have add a slight chance of light
rain in SW IL this evening to account for this and some sprinkles
further west. Otherwise expecting several waves of clouds tonight
with current mid clouds and maybe a period of low clouds up north.
SREF probs and HRRR also suggesting some potential for fog from
across northern/central MO into western IL overnight. I added a
mention of patchy fog in this region, but the overall pattern in
post-frontal air mass with building surface high pressure is at
first glance not one typically associated with a lot of fog.

.LONG TERM: (Friday through Next Thursday)
Issued at 342 PM CST Thu Dec 24 2015
(Friday)
Overall, it looks like a fairly tranquil Christmas Day across the
area. Models continue to hint at WAA along the stalled frontal
boundary to our south generating an axis of convection from AR into
the lower Ohio Valley, with our far southern counties on the very
northern fringes of this activity. The 12z solutions have the axis
of this activity just south of our area, but since the last few
model cycles have wobbled a bit with the north/south placement of
this precip, I've maintained some very low PoPs over our far
southern counties.
Otherwise, it still appears tranquil conditions are on tap for the
region, with temperatures maintaining the very mild levels that have
been commonplace this December. Highs are expected to range from
the middle and upper 40s northwest, to the middle 50s southeast.
Concern then turns to the long-advertised heavy rain threat for the
upcoming weekend and into early next week. Due to some uncertainty
to the placement of the heaviest rain have opted not to go with any
hydro headlines...yet. However, will be reissuing the EFP to
maintain awareness of the threat, which should come in two waves as
described below.
(Saturday Through Monday Night)
The long-advertised spell of wet weather should commence in earnest
either late Friday night or Saturday. Deep southerly flow is
expected to develop across the region in response to the upper level
system digging into the southwest US, and resultant isentropic
ascent over the area should be quite strong with the stalled frontal
boundary and low level baroclinic zone just to our south. In
addition, UVV across the area will be enhance by several weak
shortwaves ejecting ahead of the main system. Moisture should be no
problem as airmass will essentially be the same one that fueled
yesterdays storms in our area, with the increasing southerly flow
adding even more moisture to the unseasonably moist December
airmass. Again, models are wobbling a bit with the exact location of
the axis of the heaviest precip, but they are in excellent agreement
with the general idea that several rounds of convection will track
along and north of the frontal boundary as it attempts to push
north...from eastern OK into s MO and s IL...in the Saturday and
Saturday night time.
It appears that this first round of significant rain will wind down
on Sunday as shortwave in the northern branch of the westerlies
allows Canadian high to drop south, temporarily shutting down the
warm advection and nudging the frontal boundary back south.
Final wave of potentially heavy rain should impact the region on
Monday and Monday night as upper level low lifts out of Texas and
pushes northeast into the mid-Mississippi Valley. Again, moisture-
laden AMS ans strong UVV should produce another band of moderate to
occasionally heavy rain...with embedded thunderstorms...that will
sweep across the area.
It's not totally out of the question that we could see a bit of
wintry precip Sunday night-Monday night. First concern will be late
Sunday night and into early Monday as surface temps drop below
freezing with the southward surge of the Canadian high...while AMS
aloft remains well above freezing. This threat should be brief and
on the northern fringes of the heavier rainfall...and with the very
warm ground temperatures am not expecting much of an impact from
this. The second concern will be Monday night as the upper low
pushes across the area. It's possible that the dropping freezing
levels beneath the low could cause the rain to change over to snow,
but not certain if the lower levels will cool enough for any
prolonged period of significant snowfall.
(Tuesday-Thursday)
Medium range progs suggest long wave trof will be parked over the
central CONUS during this time frame. This will finally allow
Canadian air to dominate the region, which should yield more normal
typical wintertime temperatures.
Best holiday wishes to all...from the day shift of the National
Weather Service in St. Louis.

.AVIATION: (For the 06z TAFs through 06z Friday Night)
Issued at 1133 PM CST Thu Dec 24 2015
Weak cold front/wind shift pushed thru the terminals this evng
turning wind W/NW. SFC ridge drifts from IA tonight to the Grt
Lks by the end of the prd which allows winds to slowly back
overnight eventually bcmng erly by Fri. There have been some
scttrd sprinkles across e cntrl/SE MO into sthrn IL this evng and
these should continue for the next several hours until the forcing
moves east. For tonight...there is an area of IFR CIGs across s
cntrl IA that some guidance has making a SE push for several hours
after midnight which brings the edge of the CIGs very close to
UIN. Not confident enough in this solution to include attm but
this will have to be monitored overnight for possible updates.
Even though the set up is not ideal for fog formation...guidance
continues to indicate that at least some patchy fog may dvlp
towards mrng across cntrl/NE MO into w cntrl IL. Not confident in
this scenario either but not sure enough that it won't happen to
pull it from the going fcst. Otherwise expect mid/high clouds.
Specifics for KSTL:
VFR fcst thru the prd. Scttrd sprinkles across the STL metro
should continue for the next couple of hours until the forcing
exits east. Winds will slowly back to the east by tomorrow as high
pressure drifts from IA to the Grt Lks. MVFR CIGs may try to
encroach upon the terminal from the south late Friday night. But
since guidance indicates that if it were to happen it would be
drng the last 3 hrs of the fcst prd and of sufficiently low
confidence to preclude inclusion attm.
