Area forecast discussion...updated aviation 
National Weather Service St Louis MO 
1115 PM CDT Fri Oct 24 2014 


Update: 
issued at 945 PM CDT Fri Oct 24 2014 


Present indications are that we should see dense fog overnight 
across portions of northeast Missouri into west central Illinois. 
Its origin may be two-fold. First there could be some development 
in the moist southerly flow ahead of the weak encroaching cold 
front. However there may be a better probability in the wake of 
this boundary as it moves into northern Missouri/western Illinois late 
tonight. Quite a bit of dense fog has developed across the southeast 
half of Iowa and trajectories overnight with the passage of the 
front would bring this south-southeastward. Recent runs of the 
hrrr have been suggesting this scenario which is also supported 
by relative humidity progs in the lowest 500 feet from the NAM and the rap. I 
have issued a dense fog advisory through 14z Saturday and 
depending on trends overnight this may need to be expanded.

Short term: (tonight through sunday) 
issued at 332 PM CDT Fri Oct 24 2014 


The last vestiges of this morning's low clouds and fog is finally 
dissipating. However, clearing sky and light wind combined with 
relatively high dewpoints in the mid and upper 50s tonight will 
likely produce more fog. A weak trof of low pressure now moving 
through eastern Nebraska will also drop into the area providing a 
little lift and convergence but not much of an increase in wind. 
Unsure how low to go at this time, but at least patchy fog looks 
likely with more widespread fog in northeast MO/west central Illinois. 


Fog will likely linger into the daytime hours of Saturday morning. 
A lot of uncertainty as to how long...but at least through 14-15z 
seems likely. The trof is expected to come to a halt Saturday 
afternoon/evening near the MO/Arkansas border then begin lifting back to 
the north as a warm front as warm advection begins ahead of the next 
system. The warm front continues lifting north Sunday and decent 
mixing should give US temperatures well above normal. MOS 
temperatures through Sunday look pretty reasonable so have followed 
them closely.

Long term: (sunday night through next friday) 
issued at 344 PM CDT Fri Oct 24 2014 


Sunday night into Monday the next strong shortwave moves from The 
Rockies into the Great Plains. Strong warm advection should keep 
temperatures pretty mild...more Summer-like in fact...into Monday 
afternoon. As the surface cold front associated with the shortwave 
approaches the area Monday night, expect scattered showers and 
possibly a few thunderstorms to affect the area. Kept pops in the 
high chance/low likely range as the front moves through the area 
late Monday night into Tuesday. Rain chances should be more or less 
done by 00z Wednesday. Cooler conditions for the rest of the week 
as the upper pattern amplifies with a deep trof over eastern North 
America and a strong ridge over The Rockies. A shortwave is forecast 
to ripple by Thursday which could produce another round of light 
rain, tho differences in medium range guidance indicate slight 
chance pops are the best way to handle it at this time. Next Friday 
looks cool and dry at this time as a strong Canadian high pressure 
system slides down into the Mississippi Valley.

Aviation: (for the 06z tafs through 06z Saturday night) 
issued at 1033 PM CDT Fri Oct 24 2014 


A weak cool front will move southeastward through the area late 
tonight. Fog is expected to develop and/or advect southward into 
our area from Iowa and nwrn Illinois late tonight along/ahead of this 
front. Patchy stratus clouds is also possible as well, due to 
light surface winds near the front and relatively high surface 
dewpoints along and south of the front. The lowest visibilities 
will likely be in uin where they may drop to one quarter of a mile. 
This fog will dissipate by late Saturday morning. A S-swly 
surface wind will veer around to a nwly direction late 
tonight/early Saturday morning after fropa. The surface wind will 
become N-nely Saturday evening, albeit light as a surface ridge 
moves through the region. 


Specifics for kstl: just high level clouds late tonight and maybe 
scattered low level clouds as well. Light fog can be expected late 
tonight/early Saturday morning. A S-swly surface wind will veer 
around to a nwly direction early Saturday morning after fropa. The 
surface wind will become N-nely Saturday evening, albeit light.
