Area forecast discussion...updated 
National Weather Service St Louis MO 
909 PM CST Mon Dec 22 2014 


Update: 
issued at 909 PM CST Mon Dec 22 2014 


Rain is currently moving through the area as mid level trough 
rotates through Missouri and Illinois. Still expect area to dry 
out shortly after midnight as subsidence sets in behind exiting 
trough. Made some slight adjustments to precipitation based on 
radar trends. Otherwise going forecast still looks good.

Short term: (tonight and tuesday) 
issued at 330 PM CST Mon Dec 22 2014 


Batch one of rain is currently located from east central MO into 
south central IL, and lifting northeast. The next batch of rain 
is evolving across western MO in advance of a short wave trof 
currently extending from the ND upper low into OK. The rain will 
overspread the area this evening as the associated short wave 
rotates northeastward in advance of the southeastward moving 
upper low. Present indications are that it should be a quick shot 
with most if not all the rain out of the County Warning Area by midnight. Mid 
level drying and large scale subsidence then spread across the 
area overnight in the wake of the shortwave trof. West to east 
clearing will proceed as well overnight as the cold front advances 
and the winds veer to more westerly. Tranquil day on tap for 
Tuesday with remaining low clouds clearing but mid and high clouds 
generally overspreading the area in the increasingly southwesterly 
flow aloft associated with deepening of the upper trof through the 
plains/central U.S..

Long term: (tuesday through next monday) 
issued at 330 PM CST Mon Dec 22 2014 


Attention then turns to the storm system that will impact the area Tuesday 
night into Christmas eve day. The guidance is in general agreement that 
a closed low will develop within the deepening trof across OK by Tuesday 
evening, and then lift northeastward Tuesday night into Wednesday night. 
In response a surface low will develop on the initial cold front across 
the lower MS valley and then track northeast through the Tennessee Valley 
and into the Ohio Valley. While there is general consensus in the pattern, 
there is considerable model spread in the details of the structure 
and position and track of the important features - much greater spread 
than we normally see inside at T-60 hours. If anything there has 
been a slight general west shift in the track of the mid/upper low. 
Worrisome is the sref mean and gefs means are further west than the 
deterministic solutions, meaning there are quite a few members well 
to the west. At this point this forecast can be characterized as 
high uncertainty and low confidence. That said the current forecast 
is a uptick of the previous one with greater weighting to the 
global models - ECMWF, operational GFS and Gem. The scenario is 
that precipitation will spread from Arkansas northeastward across southeast 
MO and southwest Illinois on Tuesday night as a deformation zone develops 
in response to large scale forcing/ascent, with precipitation 
along this axis on Wednesday morning and then shifting to the 
northeast on Wednesday afternoon in association with the lifting 
system. The precipitation should be all rain through at least 06z, 
and then mix with and changeover to snow on the western fringe 
early on Wednesday morning, changing to all snow by Wednesday 
afternoon as the cold air continues to deepen. This looks like a 
wet snow with marginal surface temperatures in the lower-mid 30s 
and low slrs. The St. Louis area will be on the western fringe of 
the precipitation band. I currently have 1-2 inches forecast along 
and axis from Ellington MO to Ramsey Illinois. This may or may not be 
conservative, and will depend greatly on feature tracks and cold 
air availability. A secondary short wave rotating on the back side 
of the upper low may also bring a threat of light snow to western 
portions of the County Warning Area. 


The snow that does fall won't last long however. Low level warm advection 
gets underway by late Christmas eve and ramps up on Christmas day 
with above average temperatures into Friday. Another system could 
potentially bring another round of accumulating snow Saturday 
night into early Sunday across the southeast third of the cwa, 
however the models diverge greatly on the upper pattern at that 
time. Stay tuned.

Aviation: (for the 00z tafs through 00z Tuesday evening) 
issued at 541 PM CST Mon Dec 22 2014 


A cold front extending south across wrn MO out of a sfc low over 
wrn Iowa will push thru the terminals prior to midnight. There is 
another batch of rain that will move thru the terminals this evng 
prior to frontal passage. The front will bring winds around to the SW/west-southwest 
overnight. IFR cigs and MVFR vsbys will slowly raise overnight 
after frontal passage with low level cigs dssptg prior to 12z. There is a 
chance that KUIN will not break out of the MVFR cigs tomorrow...but 
most guidance indicates that they will. There is another batch of 
MVFR cigs poised to move into the area towards the end of the prd 
that was not accounted for with this issuance. 


Specifics for kstl: 


IFR cigs and MVFR vsbys will continue for the next several hours 
with this next batch of precip. Cigs and vsbys will begin to raise 
overnight after frontal passage with VFR conditions expected to continue for 
the remainder of the prd. Another area of MVFR cigs are expected 
to move into the terminal just beyond then of the fcst prd.
