NWS Forecaster Discussion




Area forecast discussion...updated aviation 
National Weather Service St Louis MO 
617 PM CST Thu Dec 18 2014 


Short term: (through late tonight) 
issued at 206 PM CST Thu Dec 18 2014 


Any lingering flurries or drizzle will taper off late this 
afternoon. Increased low-level moisture from today's snowfall 
along with light winds overnight will create favorable conditions 
for fog formation. Later shifts will need to monitor the potential 
for dense fog. 


Kanofsky 


Long term: (friday through next thursday) 
issued at 206 PM CST Thu Dec 18 2014 


An upper trough and its associated surface low will move across 
the central and southern Continental U.S. Tomorrow and tomorrow night. Light 
rain/snow is possible across southern/southeastern MO into 
southern IL, but the bulk of the precipitation will occur south of 
the lsx County Warning Area. A separate vort Max drops down from Canada into the 
back side of the upper trough before it swings through southern Iowa 
on Fri night/Sat. This feature could provide upper support for 
sprinkles/flurries across northern MO and west central Illinois if 
sufficient moisture becomes available. 


A clipper-like system is forecast to develop over the northern 
plains/western Great Lakes on Sunday night into Monday, then close 
off over the northeastern quadrant of the Continental U.S. During the middle 
of the week. The GFS and European model (ecmwf) exhibit differences regarding 
timing (ecmwf is slower), vort intensity (gfs is more intense), 
and the result of interactions with other disturbances. If this 
low pressure system develops as currently advertised, then it 
would be expected to produce widespread rain/snow between Monday 
and Wednesday with clouds and flurries lingering into the middle 
of the week within a cyclonic flow regime aloft. 


Temperatures will be seasonably cool on Friday and Saturday, then 
warm to around 5-7 degrees above average on Sunday and Monday 
ahead of the clipper-like system. Expect cooler temperatures for 
the middle of next week within the colder air behind the clipper 
system. 


Kanofsky

Aviation: (for the 00z tafs through 00z Friday evening) 
issued at 614 PM CST Thu Dec 18 2014 


Expect mainly MVFR and IFR conditions through the period as there 
is abundant low level moisture in the atmosphere and light winds. 
Expect IFR conditions the next 24 hours at kcou. The St. Louis 
Metro taf sites are on the edge of a large area of IFR ceilings. 
Expect current MVFR ceilings at kstl and kcps to slowly decrease 
this evening to IFR after 06z...and become LIFR between 10-17z. 
KUIN will see MVFR conditions most of the night...becoming LIFR 
late tonight into late Friday morning. All locations should see an 
improvement in ceilings and visibilities by late afternoon Friday. 


Specifics for kstl: expect current ceilings to fall below 2000 ft 
in the next hour or two with the onset of evening. Then ceilings 
and visibilities will likely slowly decrease through the night 
given the high atmospheric moisture and light winds. LIFR conditions 
are still expected between 10-17z. Do expect some slow improvement 
in ceilings and visibilities during the afternoon hours...though 
do not think they will rise above 2000ft at this time.
