Area forecast discussion...updated aviation 
National Weather Service St Louis MO 
642 PM CDT Thursday Aug 27 2015 


Short term: (through late tonight) 
issued at 251 PM CDT Thursday Aug 27 2015 


Thunderstorms over northwest Missouri have begun to diminish at 
midday in areal coverage as low level moisture convergence has 
diminished in response to low level jet backing. Believe that our 
area will stay dry through most of the night with the exception of 
the far northwestern part of the area late tonight. By late tonight 
weak shortwave trough now moving across Central High plains will 
move east supplying ascent that will eventually move into northern 
Missouri after midnight. This ascent in addition to the level jet 
which will veer again and will provide additional low level 
convergence underneath the ascent that will be enough for 
thunderstorm development later this evening and overnight over Iowa 
and northern Missouri. So will maintain a slight chance of 
thunderstorms late tonight over northeast Missouri. 


A compromise of MOS guidance looks reasonable given that they are 
close to current dewpoints with cloud cover already moving over the 
area.

Long term: (friday through next thursday) 
issued at 253 PM CDT Thursday Aug 27 2015 


Showers and storms will likely move through parts of northeast and 
central MO and west central Illinois...north and west of stl on Friday as 
a southwesterly low level jet brings increasing low level moisture 
into this area ahead of an approaching upper level trough over 
the northern plains and its associated surface low moving eastward 
through western Iowa along with its trailing cold front. The threat 
for convection may shift as far southeastward as the stl area by 
12z Saturday as the surface low moves eastward through eastern Iowa 
and drags the cold front into the northwestern portion of our 
forecast area. The convergence along the cold front will weaken as 
it moves slowly southeastward through our forecast area Saturday 
and Saturday night as the upper level trough moves eastward 
through the Great Lakes region. The NAM model seems a little too 
slow with the progression of the upper trough and associated cold 
front and may be a little too strong. Its probability of precipitation and quantitative precipitation forecast may also 
be too high for Friday night through Saturday night. Prefer the 
model solutions of the European model (ecmwf) and GFS which have lighter and more 
scattered quantitative precipitation forecast for Saturday and Saturday night. Will reduce the 
probability of precipitation into the slight chance catagory across southeast MO and 
southwest Illinois by late Saturday night and Sunday along and ahead of 
the weak cold front and a weak upper level trough...shear axis. 
Any noticeable cooling behind this front will be mainly across 
northeast MO Saturday and Saturday night. The models try to build 
an upper level ridge northeastward into northern MO for the next 
work week with weak upper level troughing or a shear axis 
remaining near southeast MO and southwest Illinois. Surface and low 
level winds will be mainly southeasterly/southerly with surface 
and 850 mb ridging east or southeast of the area. Temperatures 
should be slightly above normal. Will keep the forecast dry from 
Sunday night through the remainder of the extended forecast... 
although could not rule out a few showers/storms mainly across 
southeast MO/southwest Illinois near weak upper level lows/troughing 
..shear axis.

Aviation: (for the 00z tafs through 00z Friday evening) 
issued at 629 PM CDT Thursday Aug 27 2015 


Expect VFR flight conditions and slowly increasing south- 
southeasterly flow through Friday evening. Some fog is possible 
again tonight in river valleys, though it may not be as dense or 
long lasting as this morning. More high cloud cover and increasing 
boundary layer winds will hinder fog development...so I backed off 
prevailing 2 miles at ksus and kcps to tempo. Will see how the 
night shapes up...may need to back off further. 


Specifics for kstl: 


VFR flight conditions will prevail at Lambert through Friday 
evening. Expect the wind to gradually continue veering to the 
southeast and will increase to 8-12kts by late Friday morning.
