Area forecast discussion...updated aviation 
National Weather Service Saint Louis MO 
716 am CDT Sat Apr 30 2016 


Short term... (through late this afternoon) 
issued at 331 am CDT Sat Apr 30 2016 


It will be an active day today. Current batch of showers and a few 
thunderstorms to continue lifting northeast, slowly exiting from 
southwest to northeast by midday. Then another piece of energy to 
slide east across northern Missouri this afternoon and evening 
helping to lift surface low off to the northeast. Models in pretty 
good agreement, developing a line of convection just ahead of cold 
front associated with surface low. If atmosphere is able to recover 
from morning convection, decent convective available potential energy between 1000-2000 j/kg, lapse 
rates, and shear, could support some supercell development. Storm Prediction Center has 
kept areas along and south of I-70 in a slight risk for severe 
weather with the main threats being large hail, damaging winds and 
possibly a few tornadoes. 


As for high temperatures, it will be similar to yesterday with a 
wide gradient from around 60 far north to the mid 70s south.

Long term... (tonight through friday) 
issued at 331 am CDT Sat Apr 30 2016 


(tonight) 


Storms to lift northeast out of forecast area by 03z Sunday, with 
just some lingering showers slowly tapering off. Lows will be in the 
upper 40s to upper 50s. 


(Sunday through friday) 


Closed upper level low over Nebraska to open up and lift out of 
region on Sunday. Will see showers and a few thunderstorms across 
the area on back side of system before precipitation comes to an end 
Sunday evening. 


Surface ridge to build in with cooler temps for beginning of work 
week. Highs on Monday will only be in the low to mid 60s, a bit 
below normal for this time of year. 


Weak surface ridging to remain over region through rest of forecast 
period. Some models wanting to have upper level shortwaves under cut 
the ridge with some low chances of precipitation towards end of work 
week. For now kept this period dry with near normal temps in the mid 
60s to mid 70s.

Aviation... (for the 12z tafs through 12z Sunday morning) 
issued at 629 am CDT Sat Apr 30 2016 


Widespread area of precip assoc with a warm fnt is on schedule to 
clear the remaining terminals over the hr or two. Cigs lowered to 
IFR in the rain overnight but should slowly improve this mrng 
along and south of i70 as a warm front lifts north. The warm front 
is fcst to lift into nthrn MO and cntrl Illinois by late aftn/early 
evng. This puts KUIN right on the edge of IFR conditions north of the 
bndry and VFR to the S. I am not confident with KUIN/S fcst...ceiling 
or wind. There will be a break in the precip for the bulk of the 
day after the mrng precip exits NE before another round of 
convection dvlps along a cold front late this aftn/early this evng 
across ern MO and SW Illinois but should only last an hr or so at any 
given location. After that activity passes east...winds should 
become wrly behind the cold front. 


Specifics for kstl: 


Precip should be out of the terminal by 13z with slowly improving 
cigs thru the mrng. Winds will gradually become sthrly by aftn as 
a warm front lifts thru which will allow cigs to continue to 
improve to VFR by aftn. Another round of scttrd convection is fcst 
to dvlp drng the late aftn/early evng across ern MO. Coverage of 
this activity may limit any impacts to the terminal...though even 
a direct hit by a thunderstorm should last less than an hour. After this 
passes...expect VFR conditions for the rest of the prd.
