NWS Forecaster Discussion




Area forecast discussion 
National Weather Service St Louis MO 
250 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 areawide 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 approching 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. Lous 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. 


Cvking 


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 bulding 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. 


Cvking 


&& 


Aviation: (for the 06z tafs through 06z Friday night) 
issued at 1142 PM CDT Thu may 28 2015 


Short wave continue to lift across the area, still kickig up some 
showers in central MO. Hrrr is high on this with high MOS pops as 
well so have put a vcsh for cou and uin for some of the overnight 
hours. Next weaker wave will likely kick off more tsra Friday 
afternoon. 


Specifics for kstl: skeptical about all the precip the hrrr is 
producing before the short wave exits east central MO. Have thus 
left short term dry. Scattered tsra for Friday afternoon with more 
coverage to the north of stl. Next best shot of precipitation will 
be late in the period as the cold front begins moving into 
northern MO.
