Area forecast discussion 
National Weather Service St Louis MO 
357 am CDT Fri Sep 19 2014 


Short term: (through tonight) 
issued at 300 am CDT Fri Sep 19 2014 


Large area of sfc high pressure will move from the grt lks to off 
the NE coast with the ridge axis extending thru the Ohio rvr Vly and 
then into the sthrn plains. The morning should start off with 
some patchy fog, especially across cntrl and southeast MO, which should 
burn off by mid mrng. There will also be some scattered stratus 
floating around, again esp across MO. Stratus, transitioning to 
scttrd stratocu should persist thru the day. Friday should be a 
few degrees warmer than Thursday. Low to mid 850 mb temps in the 
low/mid teens support high temps in the upper 70s to lower 80s. 
The placement of the ridge axis should limit the amount of low 
level moisture return on the backside of the sfc high as it slides 
off the coast.

Long term: (saturday through thursday) 
issued at 300 am CDT Fri Sep 19 2014 


Energy that came ashore in the Pacific northwest yesterday is fcst to 
flatten the ridge across the plains today and then dig southeast thru the 
wknd. This will drive a cold front thru the County Warning Area late Saturday into 
Saturday night. Temps in advance of the front are expected to be a 
few degrees warmer than today which puts them above normal in the 
low/mid 80s. At least scttrd shras/tstms are expected to dvlp 
along the front during the aftn and then continue thru the aftn 
and into the overnight hrs as the front slides thru the County Warning Area. The 
front should clear the sthrn zones a few hrs shortly after 
midnight. Any lingering precip should move out of our sthrn zones 
Sunday mrng with drier air filtering in as another strong area of 
high pressure assumes control. A secondary short wave will dig 
down the back side of the trough on Sunday. The majority of the 
dynamics pass well to the NE of the County Warning Area but if this feature tracks 
further to the SW, then an increase in cloud cover will be needed 
with the possibility of adding mentionable pops. The region 
remains on the SW fringe of northwest flow thru Monday. By then the 
trough will have progressed to the East Coast. 


The remainder of the week is expected to be quiet with a persistent 
500mb ridge across the plains and large area of high pressure in 
control of the majority of the eastern part of the Continental U.S.. temps 
will slowly moderate thru the week while remaining in the 70s for 
the most part for the rest of the week, which is near normal.

Aviation: (for the 06z tafs through 06z Friday night) 
issued at 1150 PM CDT Thu Sep 18 2014 


Radiational fog has already begun developing across portions of 
the area and will continue to develop overnight. All of the 
terminals expect kstl should see visibilities drop to at least the 
MVFR range with ksus to LIFR. Fog will lift by 14z with VFR 
conditions the remainder of the day on Friday. 


Specifics for kstl: 


Patchy fog is expected across the area overnight but the feeling 
at this time is that kstl will remain void of fog with a vsby 
greater than 6sm. VFR conditions expected Friday and Friday evening.
