Area forecast discussion...updated aviation 
National Weather Service St Louis MO 
1245 PM CDT Tue Sep 2 2014 


Short term: (through Wednesday night) 
issued at 355 am CDT Tue Sep 2 2014 


Early morning sh/ts expected to continue pushing east and south with 
the sinking synoptic boundary and a veering low level jet. The Flash Flood 
Watch has been canceled early for the counties where rain has 
already ended. Additional counties may be canceled over the next few 
hours based on radar trends. 


After a lull in sh/ts over most of the area for today (except 
possibly across the southern County Warning Area in closer proximity to outflow 
boundaries and in the higher terrain of the eastern ozarks), 
precipitation chances increase again late tonight and tomorrow as 
the quasistationary frontal boundary lifts back northeastward as a 
warm front and a southwesterly low level jet begins to interact with it. 
Kanofsky 


Long term: (tonight through monday) 
issued at 355 am CDT Tue Sep 2 2014 


An approaching cold front will bring the next chance of sh/ts to 
the area late this week, however the best dynamics are forecast to 
remain north of the County Warning Area. 


Expect warm temperatures (80s-90s) through the end of the week 
followed by a rapid cool-down on Sat. The warmest day of the week 
will probably be on Thursday after the passage of a warm front on 
the previous day and in the absence of widespread precip/cloud 
cover along with 850 mb temperatures increasing to 20-22 deg c. The 
coolest days will probably be on Saturday and Sunday behind a cold 
front. The cooler weather might even last into Monday. Expect 
highs to be around 10 degrees cooler on Saturday compared to 
Friday.

Aviation: (for the 18z tafs through 18z Wednesday afternoon) 
issued at 1226 PM CDT Tue Sep 2 2014 


Celings across the area have been slow to improve today, and while 
KUIN has gone VFR, MVFR ceilings are still affecting kcou, ksus, 
kstl, and kcps. Expect improvement early this afternoon within an 
hour or two of taf valid time, with ceilings becoming scattered 
VFR and then clearing after sunset this evening. With clear skies 
expected overnight, attention then turns to potential fog 
development. Currently, it looks like Metro taf sites as well as 
kcou have a better chance to see fog, given extra available 
boundary layer moisture due to recent rainfall. Have introduced a 
few hours of MVFR fog for the aforementioned locations for the 
late overnight/early morning time frame, and a brief window of IFR 
for ksus. Otherwise, northwesterly winds today will become light 
and variable overnight, and then become southerly on Wednesday as a 
front lifts northward through the area. Showers/thunderstorms are 
possible area-wide on Wednesday afternoon as well, though 
uncertainties in timing/coverage preclude mention in the current 
taf. 


Specifics for kstl: 


MVFR ceilings are expected to improve to scattered VFR within an 
hour or two of the valid taf period this afternoon, and then clear 
after sunset later this evening. Given clear skies and ample 
boundary layer moisture, have included mention of MVFR fog for 
several hours during the late overnight/early morning time frame. 
While 12z models indicate the potential for some IFR fog 
development, mainly right around daybreak Wednesday, have not 
mentioned in the taf at this time, and will defer to later shifts 
to make the call if model trends are maintained. Northwesterly 
winds this afternoon are expected to become light and variable 
overnight, and then become southerly on Wednesday, and while 
showers and thunderstorms are possible on Wednesday afternoon, 
uncertainties in timing/coverage preclude mention in the current 
taf.
