Area forecast discussion...updated aviation 
National Weather Service St Louis MO 
103 PM CDT Tuesday Jul 7 2015 


Short term: (through late this afternoon) 
issued at 315 am CDT Tuesday Jul 7 2015 


Mesoscale convective vortex currently moving across Columbia Missouri with band of light to 
moderate rain stretching from central Illinois through southwest 
Missouri. As expected cold front is slowling its progress southeast 
with it now located from just south of Kansas City Missouri to 
Quincy Illinois. Rainfall amounts up to this point have generally 
been 1 to 2 inches across central and northeast Missouri with lesser 
amounts to the southeast. The near term radar trends suggest that 
the band of rain will continue to push east through the St. Louis 
metropolitan through sunrise with additional showers and thunderstorms 
developing along the front this afternoon as it slowly sinks south 
into southern Missouri and southwest Illinois. Temperatures are 
tricky with the front...clouds and rain. St. Louis is still 80 
degrees at 3 am in the morning. Kept the forecast nearly unchanged 
with highs in the middle 70s except the far southeast zones where 
lower 80s will be possible. 


Cvking 


Long term: (tonight through monday) 
issued at 315 am CDT Tuesday Jul 7 2015 


Focus continues to be precipitation chances. 


Cold front will continue to push southward today and push bulk of precipitation S of 
the County Warning Area by this eve, or at least across the southern portions of the County Warning Area. 
Have delayed timing of precipitation lifting northward back into the area until 
after midnight. Some question remains how quickly the next round of 
precipitation will move northward as the surface low and associated cold front lifts northward 
back into the area. This system will be responsible another round of 
heavy rain on Wednesday as the surface low passes through the region. 


Will keep the Flash Flood Watch as-is for now, but may need to be 
expanded in area as well as into Wednesday night. 


As for temps, have continued a cool trend for Wednesday due to rain expected 
through much of the day. Have lowered temperatures from previous forecast and 
future updates may need to lower these temperatures more. 


For Friday and beyond, models forecast height rises through next weekend and 
have raised temperatures accordingly. Temperatures may need to be raised more from 
going forecast, but some questions remain regarding placement of the 
surface fnt. Models forecast the fnt remaining just north of the County Warning Area this weekend 
and into next week. However, as the upper ridge builds to the W, 
area comes under northwest flow and should allow the fnt, as well as storms, 
to drop southward into the area.

Aviation: (for the 18z tafs through 18z Wednesday afternoon) 
issued at 1241 PM CDT Tuesday Jul 7 2015 


Cold front has sagged just south of the St Louis metropolitan area early 
this afternoon. Patchy Post frontal light rain or drizzle will 
continue to impact cou and the St Louis metropolitan area this afternoon 
and this evening. Uin cloud ceiling should scatter out with their 
haze dissipating later this afternoon...or at least their ceiling 
should rise into the VFR catagory. Should see the ceiling rise 
into the MVFR catagory later this afternoon or early this evening 
in cou and the St Louis metropolitan area. More significant rain or 
showers should move back into our area late tonight and Wednesday 
morning as a surface low moves northeastward into southwest MO 
Wednesday morning with the ceiling and visibility dropping again. 
Northerly surface wind will gradually veer around to an east-northeasterly 
direction tonight. 


Specifics for kstl: periods of light rain or drizzle can be 
expected this afternoon. The cloud ceiling should gradually rise 
to at least 1000 feet later this afternoon or this evening. More 
significant showers with a few thunderstorms will move back into 
the area Wednesday morning with the ceiling and visibility 
dropping again. Northerly surface wind will gradually veer around to a 
northeasterly direction tonight...and to an Ely direction Wednesday 
afternoon.
