NWS Forecaster Discussion




Area forecast discussion...updated aviation 
National Weather Service St Louis MO 
1239 PM CDT Sat Aug 1 2015 


Short term: (through tonight) 
issued at 340 am CDT Sat Aug 1 2015 


Scattered thunderstorms have recently developed over northeast 
Missouri and west central Illinois in an small area of low level 
moisture convergence. Recent runs of the rap show this forcing 
eroding around 12z. Atmosphere will become unstable again this 
afternoon...however there will be little in the way of forcing for 
it to act on. Have kept chance probability of precipitation over northeast Missouri and 
west central Illinois...particularly overnight as a shortwave trough 
will move through the upper Midwest which will likely push a mesoscale convective system 
along a frontal boundary over Iowa into into the northern County Warning Area. 


Should be another warm day across the area with 850mb temperatures 
between 18-20c. High temperatures should climb back into the low- 
middle 90s with mixing up to 850mb. 


Britt 


Long term: (sunday through friday) 
issued at 340 am CDT Sat Aug 1 2015 


(sunday and monday) 


Will continue the chance of thunderstorms on Sunday as the cold 
front moves down into the area. Chances will be lower on Sunday 
night and Monday as convergence weakens along the front as it moves 
to the southwest under northwesterly flow aloft. Both days will 
continue to be warm with MOS temperatures in the low-middle 90s and 
850mb temperatures remaining near 20c. 


(Tuesday through friday) 


It still look like middle to late next week will be unsettled with a 
continued chance of showers and thunderstorms in northwest flow 
aloft. Best chance will be Tuesday into Wednesday when both the GFS 
and European model (ecmwf) show a notable trough moving through Missouri and 
Illinois. Temperatures will fall back below normal as 850mb 
temperatures are forecast to be around 15c.

Aviation: (for the 18z tafs through 18z Sunday afternoon) 
issued at 1231 PM CDT Sat Aug 1 2015 


Specifics for kuin: initially light/variable winds will become 
southerly then turn southwesterly late in the taf period. A 
disturbance moving through Iowa is expected to support a 
thunderstorm cluster in southern Iowa overnight. If the thunderstorm 
complex develops, then sh/ts could reach KUIN after 02/06z. 


Specifics for kcou: initially light/variable winds will become 
southerly then turn southwesterly late in the taf period around 
the back side of a departing high pressure center. Scattered 
thunderstorms are possible this afternoon in vicinity of a surface boundary 
which was located across central MO at taf issuance. 


Specifics for kstl, ksus, kcps: initially light/variable winds 
will become southerly then turn southwesterly late in the taf 
period after a high pressure center has moved off to the 
southeast. A period of light to nearly calm winds may occur 
overnight at some locations, especially ksus in the River Valley. 
The remnants of overnight convection to the north could reach 
kstl/ksus/kcps after 02/10z however confidence is too low to 
introduce thunderstorms in the vicinity in the taf at this time.
