Area forecast discussion 
National Weather Service St Louis MO 
335 PM CDT Sat Aug 30 2014 


Short term: (through late tonight) 
issued at 329 PM CDT Sat Aug 30 2014 


Weakening trof of low pressure will move over the area tonight. The 
vast majority of the mid-upper level energy associated with this 
system is well north of the area over the upper Midwest, and what 
little vorticity there is in our vicinity is moving northeast away 
from the area. The surface trof is already quasi-stationary, and is 
providing a nice area of surface moisture convergence over eastern 
Missouri and southwest Illinois. Expect convection to continue to 
develop in this area of moisture convergence through late afternoon 
into early evening. Convection should loose steam within a couple 
of hours after sunset though. Some isolated showers or storms could 
continue to survive through the evening as a weak low level jet 
develops and interacts with left over boundaries, but the vast 
majority of the area should remain dry overnight. Think there will 
be some fog development before sunrise Sunday, though am not sure 
how dense it will be. First thoughts are 3-5 miles with some spots 
dropping lower. With weak southerly flow over the area, expect 
overnight lows to remain in the mid 60s to low 70s.

Long term: (sunday through next saturday) 
issued at 329 PM CDT Sat Aug 30 2014 


(sunday - tuesday) 


Seasonably warm conditions with drier weather is expected on Sunday. 
Tropical disturbance with origins in the Gulf of Mexico looks to track 
southeast of area. Cannot rule out some showers/storms over portions of 
southwest Illinois...but feel that the bulk of the precipitation should 
be across KY/TN. 


Fairly vigorous late Summer shortwave trough will quickly eject out of 
the Lee of the Rocky Mountains and move northeastward into the upper 
Midwest by 1200 UTC Monday. Combination of strong dcpva and diffluence 
aloft should help force an area of widespread showers and thunderstorms 
Sunday night somewhere across the mid-Missouri Valley. Convective 
evolution is difficult to ascertain heading into Monday...but current 
thought is that mesoscale convective system should be able to maintain itself east/southeastward 
into at least portions of central and northeastern Missouri as well as 
west-central Illinois as 30-40 kt low level jet veers. Uncertainty continues to 
increase thereafter as best dynamics head toward the US-Canadian border. 
Trailing cold frontor effective boundary from prior night's convection will 
likely stall out somewhere over the County warning forecast area and could provide a focus for 
convection in the late afternoon. Shear/cape combination certainly is 
supportive of organized severe thunderstorms including supercells due to 
orientation of deep-layer shear vector with respect to aforementioned 
boundary. Risk does look quite conditional however due to many factors 
including: 1) degree of instability due to antecedent clouds/precipitation, 
2) weak convergence along sfc fold front, and 3) ul dynamics/forcing 
displaced well to the north of County Warning Area. Temperatures also will be a challenge 
on Monday and leaned toward the cooler guidance for highs across northern 
areas and more of a blend of model guidance for southern areas. However... 
actual high temperatures do have the potential of being quite a bit 
cooler if the overnight mesoscale convective system from Sunday night propagates further 
southeastward than currently forecast. 


Monday night looks wet as frontal boundary will interact with strengthening 
nocturnal low level jet should produce widespread showers and thunderstorms over 
portions of the mid-Mississippi Valley. Main uncertainty is to exactly where 
this would transpire across the area as exact positon of sfc boundary will 
be important. For those reasons...upper pops a bit over some areas but did 
not go with categorical pops just yet. Heavy rain may also be a threat 
with convection Sunday night - Monday night due to anomalous precipitable 
water values and deep warm cloud depths. 


Did lower/shift pops on Tuesday a bit to the south and east as latest 
guidance suggests cold front or effective boundary will finally clear 
County Warning Area by Tuesday morning. Skies should at least scatter out or partially 
clear from north to south into early Tuesday afternoon. Consequently... 
did bump up high temps a degree or two with afternoon temps topping out 
in the mid 80s to near 90 degrees. 


(Wednesday - saturday) 


Active weather with chances of showers and thunderstorms looks to return 
to the region Tuesday night through Wednesday as frontal boundary moves 
back northward across area as upper-level ridge begins to amplify once 
again. Weather pattern will essentially revert to what we have seen 
predominatly over the past two weeks with upper ridging across the central 
United States and a trough in close proximity to the West Coast. What it 
means for US...above to well above normal temperatures day and night 
along with mainly dry conditions. Look for lows largely in the low 70s 
and highs in the upper 80s to low 90s to end the work week. Slightly 
cooler conditions may occur by next Saturday as upper ridge flattens 
out a bit allowing precipitation chances and cloud cover to increase 
across the region.

Aviation: (for the 18z tafs through 18z Sunday afternoon) 
issued at 1240 PM CDT Sat Aug 30 2014 


A trough of low pressure extending from north central Missouri 
southwest into southeast Kansas will remain nearly stationary 
today. This trough will provide a focus for thunderstorm 
development across the area through the afternoon into early 
evening. Expect scattered to numerous showers and thunderstorms 
this afternoon...primarily east of the trough. MVFR/IFR flight 
conditions can be expected in the areas of rain. Expect VFR flight 
conditions and light south-southwest flow outside of thunderstorms 
except for a few patches of higher mfr ceilings north of the stl Metro 
area. Showers and storms will dissipate within an hour or two 
after sunset. VFR conditions are expected until the pre-dawn hours 
of Sunday morning when fog will develop. Areal coverage and 
density of the fog is not certain at this time, but at least 
patchy mfr fog is expected. Fog should dissipate within 2 hours 
after sunrise Sunday. 


Specifics for kstl: 


Expect showers and thunderstorms to increase in coverage this 
afternoon. Timing and intensity is uncertain at Lambert, and there 
is a definite chance there could be some intermittent heavy rain 
which could reduce the visibility to IFR. However, expect VFR 
conditions to prevail for the vast majority of the afternoon. 
Showers/storms should dissipate quickly after sunset. With moist 
air in place over the stl Metro, think there will be some light 
fog at the terminal before sunrise Sunday. Fog should dissipate 
within an hour or two after sunrise.
