NWS Forecaster Discussion




Area forecast discussion 
National Weather Service St Louis MO 
357 am CDT Tue Sep 2 2014 


Short term: (through Wednesday night) 
issued at 355 am CDT Tue Sep 2 2014 


Early morning sh/ts expected to continue pushing east and south with 
the sinking synoptic boundary and a veering low level jet. The Flash Flood 
Watch has been canceled early for the counties where rain has 
already ended. Additional counties may be canceled over the next few 
hours based on radar trends. 


After a lull in sh/ts over most of the area for today (except 
possibly across the southern County Warning Area in closer proximity to outflow 
boundaries and in the higher terrain of the eastern ozarks), 
precipitation chances increase again late tonight and tomorrow as 
the quasistationary frontal boundary lifts back northeastward as a 
warm front and a southwesterly low level jet begins to interact with it. 
Kanofsky 


Long term: (tonight through monday) 
issued at 355 am CDT Tue Sep 2 2014 


An approaching cold front will bring the next chance of sh/ts to 
the area late this week, however the best dynamics are forecast to 
remain north of the County Warning Area. 


Expect warm temperatures (80s-90s) through the end of the week 
followed by a rapid cool-down on Sat. The warmest day of the week 
will probably be on Thursday after the passage of a warm front on 
the previous day and in the absence of widespread precip/cloud 
cover along with 850 mb temperatures increasing to 20-22 deg c. The 
coolest days will probably be on Saturday and Sunday behind a cold 
front. The cooler weather might even last into Monday. Expect 
highs to be around 10 degrees cooler on Saturday compared to 
Friday.

Aviation: (for the 06z tafs through 06z Tuesday night) 
issued at 1228 am CDT Tue Sep 2 2014 


Mesoscale convective system complex continues to track to the east across forecast area. 
Should see storms taper off over kcou by 07z and over Metro area 
after 09z. Did keep mention of showers for a few more hours before 
tapering off towards sunrise. As for KUIN, to remain north of 
rain. Because of weak boundaries and ridging, winds to remain 
light and variable except around storms. Clouds to scatter out by 
midday to early afternoon. 


Specifics for kstl: 
mesoscale convective system complex continues to track to the east across forecast area. 
Should see storms taper off over Metro area after 09z. Did keep 
mention of showers through 11z before tapering off. Because of 
weak boundaries and ridging, winds to remain light and variable 
except around storms. Clouds to scatter out by 20z Tuesday.
