Area forecast discussion...updated aviation 
National Weather Service St Louis MO 
709 am CDT Fri may 29 2015 


Short term: (this weekend) 
issued at 248 am CDT Fri may 29 2015 


A few showers dot the radar scope locally, but have my eyes on a 
cluster of convection increasing in coverage across eastern Kansas/OK 
early this morning. This activity is moving east at 20kt and is on 
schedule to arrive in central MO later this morning between 10 am 
and noon and eastern MO/western Illinois between noon and 3 PM. Additional 
storms will likely form this afternoon area wide as the atmosphere 
destabilizes. Widespread severe weather is not anticipated, but 
just like yesterday a few stronger storms could produce some local 
wind gusts and/or small hail. Temperatures will range from the 70s 
in central Missouri to the 80s across eastern MO and Illinois. 


Meanwhile, a cold front will begin approaching the area from the 
northwest this evening which will shift the focus for convection to 
our northern County Warning Area. The front will move southeast across the County Warning Area 
tonight and Saturday, reaching St. Louis around 18z. The best chances 
of showers and thunderstorms will accompany the front with a 
clearing trend from northwest to southeast Saturday afternoon and 
evening. Temperatures on Saturday will depend on convective trends 
and frontal position, but generally think upper 60s northwest to 80s 
southeast. 


Sunday appears to be dry now as the front pushes south and a ridge 
of high pressure builds across the region. It will be a cooler day 
with highs struggling to reach 70 degrees.

Long term: (monday through thursday) 
issued at 248 am CDT Fri may 29 2015 


A cutoff low is expected to develop across the lower Mississippi 
River valley underneath a building ridge of high pressure aloft. 
Appears the cutoff will stay far enough south that pops will be 
limited and temperatures should increase through the period back 
into the middle 80s. Next trof of low pressure approaches on 
Thursday with an increased chance of showers and thunderstorms 
across the western County Warning Area.

Aviation: (for the 12z tafs through 12z Saturday morning) 
issued at 707 am CDT Fri may 29 2015 


Timing of precipitation still hard to pin down. For now have 
vicinity showers at kcou and KUIN this morning, then as system 
moves closer will see scattered storms develop at all taf sites 
between 17z and 19z. More predominate area of storms to move in 
this evening, so have MVFR conditions with storms after 01z-04z 
Saturday. Then some showers behind system late tonight, so have 
vicinity showers after 10z Saturday with MVFR cigs persisting. 


Specifics for kstl: 
timing of precipitation still hard to pin down. For now as system 
moves closer will see scattered storms develop in Metro area after 
19z. More predominate area of storms to move in this evening, so 
have MVFR conditions with storms after 04z Saturday. Then some 
showers behind system late tonight, so have vicinity showers after 
11z Saturday with MVFR cigs persisting.
