NWS Forecaster Discussion




Area forecast discussion...updated aviation 
National Weather Service St Louis MO 
624 am CST Wed Nov 26 2014 


Short term: (today and tonight) 
issued at 310 am CST Wed Nov 26 2014 


Clipper system over Nebraska/Iowa border will continue to drop 
southeast today, bringing the area some light snow/rain. Short 
range guidance including the hrrr, rap, NAM and GFS are in good 
agreement that light precip will overspread the area through the 
morning hours, reaching the Mississippi River between 16-18z. 
Primary lifting mechanisms continue to look like low level 
moisture convergence, frontogenesis, and broad scale lift 
generated by the parent shortwave. Precipitation will initially 
have to fight some pretty dry low level air as it moves into the 
area as dewpoints are in the upper teens and low 20s. Evaporative 
cooling as well as favorable vertical profiles would indicate that 
initially most if not all of the precipitation will fall as 
snow...especially over central and northeast Missouri. Insolation 
through later in the morning and afternoon, combined with 
southerly flow along and east of the Mississippi River (which will 
be east of the low track) will probably cause the snow to mix with 
rain across a good portion of the area for at least part of the 
afternoon. Between the mix, above freezing temperatures, and warm 
ground conditions (2 inch soil temperatures range from 32 to 40 
degrees across the area), expect only minor accumulations of and 
inch or less today. The tail end of the clipper will continue to 
affect the area this evening with additional minor accumulations 
possible...generally along and east of the Mississippi in 
southeast Missouri and southwest Illinois. The lingering 
precipitation should end before 06z this evening.

Long term: (thursday through tuesday) 
issued at 410 am CST Wed Nov 26 2014 


Quiet period of weather for Thanksgiving day through Saturday as the 
pattern transitions from high amplitude to more zonal. After a cold 
day on Thanksgiving with highs struggling into the upper 20s to mid 
30s, the trof currently over the eastern Continental U.S. Will shift offshore 
by early Friday morning which will start a moderating trend. Low 
level southwest flow will bring temperatures up to near normal in 
the low 50s, and temperatures will warm further on Saturday into the 
upper 50s and low 60s. Continuing to keep a dry forecast on 
Saturday in spite of the GFS and European model (ecmwf) which continue to spit out 
light quantitative precipitation forecast. Still think this is due to the rapidly moistening 
boundary layer and the model's tendency to make precipitation when 
this occurs. Sunday's highs are still in question as a 1035mb high 
dips down into the northern plains and upper Midwest. The resulting 
cold front will be moving into northern sections of our area during 
the day which makes high temperature forecasts for Sunday quite 
difficult. Should be mild south of the front with highs in the 50s 
and 60s...possibly warmer. North of the front it will be sharply 
colder. As there will be frontal-scale lift as well as weak low 
level moisture convergence, have kept low chance pops in the 
forecast south of the front in the warm sector. High will shift 
eastward Monday and Tuesday. Medium range guidance agrees that 
Monday should be cool and dry under the influence of the high, with 
the potential for temperatures rising back above normal for Tuesday 
as southerly flow returns to the area.

Aviation: (for the 12z tafs through 12z Thursday morning) 
issued at 615 am CST Wed Nov 26 2014 


Surface low of clipper appears to be near adu in western Iowa at 
11z, with north-S band of precip in zone of warm air advection ahead of system 
stretching from east of dsm to dmo. The precip should rotate east 
during the morning, with the band of precip setting up along the 
Mississippi River around midday and then spiralling its way into 
southern Illinois and western Kentucky during the aftetrnoon as low tracks 
into the lower Ohio Valley by evening. Have attempted to time 
arrival and decrease of precip with a blend of sref, hrrr, and 
local WRF. 


Latest forecast soundings indicate that precip should mainly be 
snow in uin (arriving in the 16-17z time frame), with occasional 
IFR cigs/vsbys in the bands of heavier snow. Further S, it still 
appears that the precip could go either way (rain or snow) as 
evaporative cooling attempts to offset low level warming. In this 
transition area, gone with prevailing MVFR cigs in rain/snow mix, 
with the thinking that IFR conditions will occur for a time as the 
stronger lift produces heavier precip, with the resultant evaporative 
cooling lowering the freezing level so that it falls as all snow. 


Any significant precip should taper off to flurries heading into 
the evening, primarily along the Mississippi River. It appears 
that considerable low cloudiness will work south across the region 
in the wake of the clipper, so have maintained MVFR cigs 2-3kft overnight. 


Specifics for kstl: band of precip currently over western MO 
should work into stl area between 16-18z. Thermal profiles still 
suggest a mix of rain/snow, and have gone with prevailing 
cigs/vsbys in the MVFR range, with occasional IFR for pockets of 
heavier precip where evaporative cooling will cause the precip to 
fall as all snow. Precip should taper off to flurries this 
evening, with MVFR cigs lingering throughout the night.
