Area forecast discussion...updated aviation 
National Weather Service St Louis MO 
607 am CST sun Dec 21 2014 


Short term: (through late this afternoon) 
issued at 340 am CST sun Dec 21 2014 


A full latitude trof is moving through the Great Plains this 
morning; and although the pattern is relatively low amplitude, the 
trof will begin deepening today as the strong shortwave over the 
Pacific northwest moves rapidly across The Rockies and dives into 
the Great Plains. This will result in increasing southerly flow in 
the low levels as the trof deepens over the plains. Unfortunately, 
plenty of moisture will remain trapped under the persistent 
inversion which has been locked in over the County warning forecast area for the past few 
days. Present indications are that the sky will remain cloudy 
across most of the area today; but there is potential for some 
breaks in the overcast during the afternoon along and south of the 
I-44 corridor. Highs today will likely be near or just a few 
degrees warmer than yesterday's temperatures.

Long term: (tonight through saturday) 
issued at 340 am CST sun Dec 21 2014 


(tonight - wednesday) 


There remains good model consensus on a deep longwave upper level 
trough becoming established over the central Continental U.S. By Monday...right 
over our region...and then taking until Wednesday before exiting. 
It is the specifics on the last 24 hours that remains elusive and 
probably will for at least another day or so until a critical 
component can finally come ashore. 


The initial phase tonight and Monday will feature some deepening of 
the trough to our west with most of the pcpn staying to the north and west of 
stl Metro. Pcpn-types here will be all liquid. 


The middle phase Monday night and Tuesday will then feature 
significant deepening and amplification of the trough with higher 
levels of moisture and additional disturbances riding northward. At 
this time, it looks like much of the moisture will get shunted off 
to the east and so have the best pops generally for stl Metro and 
areas to the S and east. Pcpn-types once again will be all liquid. 


The final phase for Tuesday night and Wednesday, arguably the most 
important one, is where the models still have significant diffs on. 
All solutions continue to trend slower with bringing the trough axis 
thru our region, but differ on exactly how to do that. The GFS is 
the most extreme in closing off a low over western Arkansas and then 
tracking it northeast into the lower Ohio Valley. This would paint a 
solution of accumulating snow for a good chunk of our region late 
Tuesday night into Wednesday (christmas eve). The ec and Gem 
continue to lead the opposition by maintaining an open wave with 
this southern disturbance and maintaining a low to the north. This 
would end up leaving very little pcpn back in the cold air with what 
edges US from the deformation zone well to the north and scattered 
shsn in its wake. Spotty dustings of snow would be the likely 
result here. Both the 00z and 06z NAM have somewhat more of a 
compromise between these two camps. Vertical temp profiles favor 
rain changing to snow for most areas Tuesday night, especially west 
of stl city, continuing to trend snowier for Wednesday. Sufficient 
cold air should be aloft to not have to worry about mixed pcpn, 
especially if the GFS verifies, with upper los notorious for 
manufacturing their own cold air, and will almost exclusively come 
down to temps in the lowest 2kft of the atmosphere, with decent 
correlation to surface temps: where surface temps are mid 30s or 
below, this should favor mostly snow, with liquid for upper 30s and 
up. Have maintained the going course of preferred snow for the 
pcpn-types but spreads are much too large to properly speculate on 
amounts or impacts at this time, but with surface temps mostly above 
freezing and recent mild air, it will take strong snowfall rates to 
successfully achieve decent accums anyway and would need the GFS 
solution to win out. 


Mild temps forecast thru Tuesday, with below normal temps for 
Wednesday. 


(Christmas) 


Models continue to advertise a transitional pattern this day with 
quiet wx and temps returning to above normal levels. 


(Friday - saturday) 


There is better model agreement than 24hrs ago, with a 
re-establishment of a longwave upper trough over the central Continental U.S. And 
an area of sheared vorticity moving thru. Coupled with a cold front 
on Friday, it is Worth a pop mention but amounts look sparse at this 
time.

Aviation: (for the 12z tafs through 12z Monday morning) 
issued at 556 am CST sun Dec 21 2014 
MVFR flight conditions will prevail across most of the area for 
much of the day today. Expect that ceilings will improve to VFR 
along and south of the I-70 corridor, and there will probably be 
some breaks in the overcast across southeast Missouri and southern 
Illinois. 


Specifics for kstl: 
MVFR flight conditions will prevail at Lambert this morning. 
Ceilings should improve to VFR this afternoon, although timing is 
uncertain. VFR ceilings will likely hold through the night, but 
should fall again sometime Monday morning. Timing of the falling 
ceilings and heights are uncertain at this time.
