Area forecast discussion...updated 
National Weather Service St Louis MO 
945 PM CDT Fri Apr 17 2015 


Update: 
issued at 945 PM CDT Fri Apr 17 2015 


Other than some minor tweeks to temperatures and clouds, the 
current forecast looks on track. The latest high res short range 
guidance continues to give some indications that we could see a 
few showers overnight, especially in the predawn hours, in central 
and north central MO where low pops reside. This would be along the 
eastern periphery of strongest 850 mb winds and deeper moisture 
and thus looks reasonable.

Short term: (through late tonight) 
issued at 317 PM CDT Fri Apr 17 2015 


A weak upper level ridge continues to persist overhead this 
afternoon with a vigorous upper low spinning over southern Colorado. A 
lobe of vorticity which was helping to drive a broken band of 
showers and storms across far western MO is in the process of 
weakening, and as a result, the pcpn associated with it is 
fizzling. Another stronger upper level disturbance was over far 
western Tennessee and northeast Arkansas which was igniting convection there. 
Once again we saw an explosion of flat diurnal cumulus with the 
heating of the day, but it did not prevent temps from reaching well 
into the 70s to near 80. 


The lobe of vorticity should continue its weakening trend as it 
slides north-NE and edges the western County Warning Area/central MO this evening while 
the stronger upper level disturbance will continue chugging east and 
remain well to our south and southeast. This will leave weak 
lift--at best--for much of the duration of tonight across our region 
and will favor a dry forecast for many areas. Have only had to make 
minimal changes to previous forecast, but backed off on the low 
chances a bit further, limiting them to only some sections of 
northeast and central MO and to just the hours immediately preceding 
dawn. 


Temps look to be a bit warmer than persistence with what should be 
increasing clouds from the west late and a bit stronger southeast 
flow but many areas should still get into the 50s, albeit only 
briefly, before sunrise.

Long term: (saturday through next friday) 
issued at 317 PM CDT Fri Apr 17 2015 


Models are now a little slower with onset of showers and 
thunderstorms on Saturday, with best chances over central MO 
Saturday afternoon. Otherwise, will see highs in the low to mid 70s 
with coolest temps over central MO due to the cloud cover and 
precipitation. 


Models persistent in developing a strengthening low along warm front 
with it lifting northeastward from the MO bootheel to Southern Lake 
Michigan by Sunday evening. So now forecast area remains on cool 
side of system with severe chances on Sunday afternoon and evening 
looking less likely most locations, though far southern portions of 
forecast area could still see some severe weather. Showers will be 
predominant on Sunday with less instability expected so adjusted 
weather grids to just mention showers with a chance of 
thunderstorms. Overall could see widespread one inch rainfall 
amounts through the weekend. 


Precipitation comes to an end by Monday with cooler and drier 
weather for the first part of the work week. Then extended models 
try to bring in another wet period from Tuesday night through Friday 
but confidence is low on timing and placement of precipitation so 
kept slight chance/chance pops through this period. Highs will be 
60s Monday through Friday with overnight lows in the 40s.

Aviation: (for the 00z tafs through 00z Saturday evening) 
issued at 549 PM CDT Fri Apr 17 2015 


Specifics for kcou, kuin: VFR conditions are likely for the first 
0-6 hours of the taf period. Scattered rain showers/thunderstorms and rain are possible at 
kcou after 12z and should become more widespread after 18z when a 
low pressure system gets closer to the area. KUIN is far enough 
east that the best precipitation chances should hold off there 
until after 19/00z. 


Specifics for kstl, kcps, ksus: VFR for at least the first 0-12 
hours except at ksus where some light fog is possible towards 
daybreak. Elsewhere, high clouds should interfere with any 
fog/stratus formation overnight. Rain showers/thunderstorms and rain are possible during the 
afternoon but the best opportunity for precipitation will be 
after 19/00z.
