NWS Forecaster Discussion




Area forecast discussion...updated aviation 
National Weather Service St Louis MO 
652 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. 


Kanofsky

Aviation: (for the 12z tafs through 12z Wednesday morning) 
issued at 633 am CDT Tue Sep 2 2014 


A small area of showers and thunderstorms has quickly developed 
since 1115z just to the northeast of kstl. Unless they develop 
further to the west southwest I think that all the taf sites 
should be void of precipitation. Areas of IFR and MVFR cigs cover 
portions of the area this morning and additional broken MVFR cigs 
are forecast to develop this morning before scattering out by 
midday. VFR conditions are then expected from the afternoon 
through tonight. Will need to keep a close eye on showers and 
thunderstorms developing over western MO tonight. Think these will 
stay west of kcou through 12z Wed. 


Specifics for kstl: 


A small area of showers and thunderstorms has quickly developed 
since 1115z just to the northeast of kstl. Unless they develop 
further to the west southwest I think that a sprinkle is all kstl 
will see over the next hour or so. Otherwise the terminal is 
surrounded to the north and east by areas of IFR and MVFR cigs. 
Additional broken MVFR cigs are forecast to develop this morning 
before scattering out by midday. VFR conditions are then expected 
from the afternoon through tonight.
