Area forecast discussion...updated aviation 
National Weather Service St Louis MO 
713 am CDT Sat Apr 25 2015 


Short term: (through this evening) 
issued at 240 am CDT Sat Apr 25 2015 


Well advertised storm system will bring two rounds of showers and 
thunderstorms to the County Warning Area over the next 12 hours. The first round is 
just now taking shape as warm advection increases ahead of the 
shortwave now lifting from the Southern Plains into the lower 
Missouri River valley. Surface low pressure depicted by model 
guidance the past few days seems to be associated with well defined 
mesoscale convective vortex on regional radar currently spinning in far southeast Nebraska. 
Showers and thunderstorms should continue to develop from northwest 
Missouri to southeast Missouri and lift north through the predawn 
hours. Dry slot will push through the southeastern half of the County Warning Area 
ahead of the low pressure this morning and early afternoon. This 
will cause the band of warm advection showers and thunderstorms to 
steadily March northeast of the County Warning Area. It will also set the stage for 
at least some breaks in the cloud cover south of Interstate 70 and 
instability to increase this afternoon. 


The second round of precipitation today will take shape later this 
morning and into the afternoon as the low pressure center traverses 
east-southeast across the County Warning Area. Rain showers and isolated 
thunderstorms will accompany the low pressure center (mcv) and 
additional thunderstorm development is likely ahead of and to the 
south of the surface low. Storm Prediction Center continues to highlight the likelihood 
of severe thunderstorm development this afternoon, mainly southeast 
of the St. Louis Metro. Latest explicit model guidance depicts 
discrete storm development between 2 PM and 4 PM just south of St. 
Louis, with this activity exiting the County Warning Area shortly after 7 PM. Large 
hail and damaging wind gusts will be the primary threats with the 
supercells this afternoon and early this evening. The threat of 
tornadoes is more conditional and will likely hinge on how much 
instability can be realized ahead of the low and if the surface 
winds can remain backed across this area. 


Cvking 


Long term: (tonight through friday) 
issued at 240 am CDT Sat Apr 25 2015 


Showers will come to an end from northwest to southeast this 
evening and clearing is still expected on Sunday with below normal 
temperatures. Rest of the forecast remains unchanged with 
temperatures gradually returning to normal by the end of the week 
and precipitation chances remaining low.

Aviation: (for the 12z tafs through 12z Sunday morning) 
issued at 642 am CDT Sat Apr 25 2015 


Aviation overview: a slow-moving low pressure system will move 
east-southeast across the region today. Periods of rain showers/thunderstorms and rain are 
expected at all taf sites at different times of the day depending 
on each terminal's location relative to the track of the low 
pressure system. A trailing cold front will then move through the 
region tonight behind the departing low pressure system. 


Specifics for kcou: initially IFR ceilings at taf issuance should 
improve to at least MVFR for several hours before additional 
rain showers/thunderstorms and rain develop during the afternoon. Cigs should eventually 
fall back to IFR tonight on the cold side of the cold front. 
Initially southeast winds will veer and become southerly to 
southwesterly today, then become northeasterly early tonight 
behind the cold front. 


Specifics for kuin: based on upstream trends, prolonged periods 
of rain showers/thunderstorms and rain are expected at KUIN since it will be located north 
of the surface low track. One cluster of thunderstorms was located 
just upstream from KUIN at taf issuance, and it should reach the 
terminal by 13z. Initial thoughts are that KUIN should be too far 
north to be affected by much in the way of afternoon thunderstorm 
development, although a few embedded thunderstorms may occur. If 
any clearing occurs at KUIN this afternoon, then the resulting 
instability will aid thunderstorm development. Initially 
southeasterly winds will back and become easterly to northeasterly 
today, then remain northeasterly through the end of the taf 
period. 


Specifics for kstl, ksus, kcps: the southern end of a rain showers/thunderstorms and rain 
cluster was approaching St. Louis Metro area terminals at taf 
issuance. After the morning convection tapers off, there should be 
a dry period lasting several hours before the next round of 
thunderstorms develops during the afternoon. After some 
improvement during the late morning or early afternoon, cigs are 
expected to fall back to MVFR tonight on the cold side of the 
cold front. Initially southeasterly winds will veer and become 
southerly to southwesterly today, then turn northeasterly early 
tonight behind the cold front.
