NWS Forecaster Discussion




Area forecast discussion 
National Weather Service St Louis MO 
320 am CST Sat Dec 20 2014 


Short term: (through late this afternoon) 
issued at 320 am CST Sat Dec 20 2014 


Dirty ridge remains over the area today with abundant low level 
moisture trapped beneath an inversion around 850mb. Flurries are 
currently falling at weather forecast office lsx out here in Weldon Spring, so have 
updated the forecast to include flurries along and west of the 
Mississippi for a few hours this morning. Forecast soundings 
indicate that the lower atmosphere should warm sufficiently to 
preclude any frozen precipitation by around 15z, and weak low level 
lift should be subsiding by mid-day as the upstream shortwave which 
is currently over northwest MO/eastern NE moves into Illinois. Was 
a little too cool on yesterday's highs...and today's temperatures 
may be tricky as well with variable cloud heights and thicknesses 
across the region. Used a blend of MOS guidance, but tried to lean 
toward the warmer numbers except over northeast Missouri and west 
central Illinois where clouds should generally be thicker allowing 
for less insolation. 


Carney 


Long term: (tonight through friday) 
issued at 320 am CST Sat Dec 20 2014 


(tonight) 


Southerly flow is expected to take some toll on the rather extensive 
area of low clouds currently entrenched across the area. The areas 
that stand the best chance of seeing some clearing will be south and 
east of stl Metro and went cautiously optimistic with the forecast. 
Any clearing should be short-lived with mid and high clouds 
increasing heading into Sunday with the next system. 


Prefered the warmer met MOS for areas north and west of stl Metro 
where clouds should hang tough, but a MOS blend preferred for areas 
in the south and east where some clearing looks likely. 


(Sunday - wednesday) 


The beginnings of what will be a deep upper level trough is expected 
to develop later on Sunday over the central Continental U.S. And then take at 
least until Wednesday before finally shifting east. 


An initial impulse will begin to lay the groundwork for this to 
happen late Sunday night and Monday...with pops primarily confined 
to the northern part of MO and central Illinois. The highest pops were 
reserved for Monday night and Tuesday with a very favorable synoptic 
setup with a more mature deep trof, upstream, and a significant 
impulse rotating around the base of the trough. Pcpn-types thru 
Tuesday afternoon look to be all liquid, however. 


Things begin to get interesting Tuesday night into Wednesday with 
most model solutions closing the system off and with the cold air 
thus generated from this closing off, the pcpn will turn to snow. 
Where and when this system closes off will be critical. The current 
model consensus favors this to occur late Tuesday night almost 
directly overhead of our region. If this stands, snow will be 
possible at the end of the event later on Tuesday night and 
transition to snow showers Wednesday with light accums possible. 
Something to watch closely...because...an earlier closing off and/or 
a more Western Location for the closing off of the system (per the 
dgex and 06z nam) would mean a substantial increase in snowfall 
potential for parts of our area...such as what the consensus 
solution currently shows for parts of eastern Illinois. 


Temps will be at or above normal thru Tuesday, with a return to 
below normal values on Christmas eve in the wake of the system. 


(Christmas) 


Models continue to advertise a transitional pattern this day which 
is a good sign for quiet wx with near seasonal temps. 


(Friday) 


Models all diverge significantly on how to handle the next system 
and so very low confidence on not just pops but also pcpn-types with 
a rather large spread in temp profiles. A lot of how this pans out 
will depend on exactly how the Tuesday-Wednesday system develops.

Aviation: (for the 06z tafs through 06z Saturday night) 
issued at 1119 PM CST Fri Dec 19 2014 


VFR conditions have persisted through the evening hours at KUIN 
and the St. Louis Metro taf sites because of drier air moving in 
from the east. MVFR conditions are expected to move into these taf 
sites between 06-09z as large area of lower ceilings over the 
western two-thirds of Missouri expands eastward overnight. Still 
expect visibilities to fall to 2sm at ksus which lies in the 
Missouri River valley. These MVFR and IFR conditions will then 
likely persist through the morning hours before there is some 
improvement by early afternoon. Also, some patchy drizzle or 
freezing drizzle is possible at kcou and KUIN between 09-15z, 
though chances are too low to include in the taf. 


Specifics for kstl: expect mfvr conditions to move into the 
terminal by 08z as large area of MVFR ceilings to the west of the 
terminal expands eastward. Expect these conditions to last through 
at least midday on Saturday.
