NWS Forecaster Discussion




Area forecast discussion 
National Weather Service St Louis MO 
501 am CDT sun Aug 2 2015 


Short term: (through late this afternoon) 
issued at 455 am CDT sun Aug 2 2015 


Thunderstorms have developed early this morning over south central 
Iowa in an area of low level moisture convergence on the nose of a 
30kt low level jet. Rap shows that this low level convergence will 
move across the northern part of the County Warning Area this morning. Will keep 
isolated thunderstorms going over this area through at least the 
morning hours. 


Went with a blend of the MOS guidance for highs today which is 
supported by mixing down the 850mb temperatures. 


Britt 


Long term: (tonight through saturday) 
issued at 455 am CDT sun Aug 2 2015 


(tonight through tuesday) 


Cold front will move down into the area tonight ahead of a weak 
shortwave in northwesterly flow aloft. Still expect scattered 
thunderstorms to develop in the weak moisture convergence along 
the cold front in areas along and north of I-70. Isolated 
thunderstorms will continue into Monday over the southern half of 
the County Warning Area as the cold front shifts to the south. Chances for storms 
will increase Monday night into Tuesday night as the front stalls 
over the area as stronger shortwave trough moves across the area. 


(Wednesday through saturday) 


The chance of thunderstorms will continue over the area through 
Friday as the front will remained stalled Missouri and Illinois. 
Both the European model (ecmwf) and GFS are showing a series of shortwaves moving 
over the stalled front during this period. High pressure will 
finally move into the area by Saturday providing a dry day. Went 
with below temperatures because of expected clouds and rain chances.

Aviation: (for the 06z tafs through 06z Sunday night) 
issued at 1119 PM CDT Sat Aug 1 2015 


Still expecting development of showers and thunderstorms likely 
over central Iowa in the predawn hours of Sunday morning. Quincy 
may be on southern edge and maintained a vc group for early Sunday 
morning. Although cannot totally rule out activity further south 
late Sunday morning/early afternoon chances are pretty low so kept 
remaining sites dry. West/southwest winds will pick up and gust 
at kcou and KUIN as surface pressure gradient tightens but will relax 
a bit with approach of next cold front Sunday night. 




Specifics for kstl: 


VFR conditions are expected to continue through Sunday night. 
Light/variable winds will become predominantly southwesterly by 
late Sunday morning. Next cold front will approach from the 
northwest late Sunday night but precipitation chances once again 
do not look too high with it and passage of said actual front 
looks to be actually on Monday morning.
