NWS Forecaster Discussion




Area forecast discussion 
National Weather Service St Louis MO 
411 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 06z tafs through 06z Wednesday night) 
issued at 1125 PM CST Tue Nov 25 2014 


VFR flight conditions and dry weather will persist overnight with 
clouds increasing and thickening across the region. A northwest 
flow storm system is still on track to impact the area on 
Wednesday with precipitation spreading in kcou around 14z and KUIN 
and the St. Louis area terminals between 16-17z. Temperature 
structure at the onset of the precipitation suggests all snow at 
kcou and KUIN with predominately MVFR flight conditions, while 
there is more uncertainty in the ptype at and kstl/ksus/kcps with 
snow at the onset and then mixing with rain. Flight conditions 
could lower into the IFR category during the precipitation. 
Precipitation should taper to very light snow/flurries by mid- 
afternoon to evening with a northwest wind shift as the system 
passes. 


Specifics for kstl: 


VFR flight conditions and dry weather will persist overnight through 
mid morning on Wednesday with clouds increasing and thickening. A 
northwest flow storm system will impact the area on Wednesday with 
precipitation spreading into kstl between 16-17z. There is some 
uncertainty in the ptype, however the current thinking is that we 
will see snow at the onset and then mixing with rain in the afternoon. 
Flight conditions could lower into the IFR category during the 
precipitation. Precipitation should taper to very light snow/flurries 
by early evening with a northwest wind shift as the system passes.
