Area forecast discussion...updated aviation 
National Weather Service St Louis MO 
553 PM CDT Wed Jul 30 2014 


Short term: (through tonight) 
issued at 157 PM CDT Wed Jul 30 2014 


Not many changes in store for tonight. Diurnal cu will dissipate 
after sunset, but CI shield shud remain largely in place. Short wave over 
Kansas/OK region shud begin to dig slightly as the upper low over 
Hudson Bay helps to push it swd. This shud keep precip S of the 
County Warning Area overnight. Latest radar trends show precip is further north than 
mdl guidance suggests. However, much of the precip over SW MO is 
largely convective and shud gradually dissipate, at least 
partially, after sunset. All of that said, have added slight pops 
to the srn tier of counties late tonight to account for 
uncertainty in the nrn edge of the precip shield. 


As for temps tonight, with light winds and clouds clearing out, 
have trended twd the cooler guidance tonight except for srn 
portions of the County Warning Area where clouds will linger thru the night. 


Tilly 


Long term: (thursday through next wednesday) 
issued at 251 PM CDT Wed Jul 30 2014 


Persistent longwave trough is still forecast to dominate the 
weather pattern through the rest of the work week and into this 
weekend. Complex of light/moderate rain should stay mainly south 
of the area through Thursday with far southern sections of the 
County warning forecast area possibly being either skirted by the rain shield or isolated 
-shra/-tsra that develops with diurnal instability Thursday 
afternoon. Slight chance of showers or storms will again be 
diurnally driven on Friday/Saturday. Sunday through Tuesday at 
least looks dry with slowly moderating temperatures to near normal 
by Tuesday. Next best chance of any widespread sort of rain looks 
to be next Wednesday/Thursday as flow aloft becomes more zonal and 
a frontal boundary slowly progresses through the region.
