Area forecast discussion...updated aviation 
National Weather Service St Louis MO 
715 PM CDT Tuesday Jul 7 2015 


Short term: (tonight through Wednesday night) 
issued at 320 PM CDT Tuesday Jul 7 2015 


The front continues to sag southeastward and extends from the Ohio 
Valley across southern Illinois and southeast MO into eastern OK at middle 
afternoon. The majority of the heavy rainfall has shifted south of 
the region at this time, but a broad persistent southwesterly low level jet 
continues to generate showers well to the north of the surface 
front. I don't anticipate major changes into the evening with 
showers and maybe some drizzle the dominant precipitation and a 
better threat of showers and any thunderstorms confined to the far 
southern County Warning Area in the immediate vicinity of the quasi-stationary 
front. Overnight however things will change as the short wave 
currently centered through western OK lifts east northeast. In 
response the western portion of the front will lift northward as 
the associated surface low tracks northeast along it, and low and 
middle level flow will back and strenghthen. This should lead to the 
spread and development of more continous showers and thunderstorms 
with heavy rain back into the area from the southwest. 


Wednesday into early Wednesday evening still appears to be the 
period of heaviest rainfall and flash flood potential. The overall 
scenario remains the same with the surface low tracking east 
northeast prompting the front to lift northward, and continued 
strengthening and backing of the southerly low level jet producing strong 
lift/mcon along and north of the front and surface low. Present 
indications are that the axis of highest rainfall totals should be 
centered in the vicinity of a Jefferson City to Litchfield axis, 
although precipitation will be widespread. Have leaned the 
forecast towards the GFS/ECMWF, which is a bit faster than the 
NAM, but still has a threat of showers and thunderstorms and 
heavy rain during the evening across far eastern MO into Illinois. 
Accordingly I extended the Flash Flood Watch in this area until 
06z Thursday. There could also be a conditional severe weather 
threat across the southeast half of the County Warning Area Wednesday afternoon/evening 
depending on the amount of destabilization which can occur as low 
level shear will be favorable along and in advance of the surface 
low. 


Glass 


Long term: (thursday through next tuesday) 
issued at 320 PM CDT Tuesday Jul 7 2015 


The front will sag back into southern MO and southern Illinois by 
Thursday morning in the wake of the departing surface low and the 
best threat of the scattered showers and storms will be across the 
far southern County Warning Area in the vicinity of the front. The final hurrah 
will be Thursday night into early Friday morning as the final 
disturbance aloft tracks east northeast out of the plains 
resulting in the same sequence of a migratory surface low and 
lifting front with showers and thunderstorms likely along and 
north of the front. This front and the threat of precipitation 
should be north of the area by Friday afternoon. Thereafter heat 
and humidity will dominate the area late Friday into the weekend 
as heights rise aloft in association with a large upper high/ridge 
building into the Lower/Middle MS valley. This upper high continues 
retrograding to the west by early next week bringing a return of 
troffing in the east, northwest flow aloft for US, and another 
frontal passage in the Monday/Tuesday time frame with a threat of showers 
and thunderstorms.

Aviation: (for the 00z tafs through 00z Wednesday evening) 
issued at 706 PM CDT Tuesday Jul 7 2015 


With front stalled south of forecast area, most taf sites remain 
on the cool side with MVFR/IFR ceilings/visibilities in light rain/drizzle.

before front begins to lift back north on Wednesday and ceilings lower 
to MVFR. Reintroduced rain at KUIN by 15z Wednesday. As for sites 
along I-70 corridor, light rain to persist with chance of 
thunderstorms by midday Wednesday so have vicinity ts mention. 
Otherwise, northeast winds to veer to the east as front begins to 
lift north. 


Specifics for kstl: 
with front stalled south of forecast area, kstl to remain on the 
cool side with MVFR/IFR ceilings/visibilities in light rain. Will see chance 
of thunderstorms by 18z Wednesday so have vicinity ts mention for 
remainder of forecast period. Otherwise, northeast winds to veer 
to the east as front begins to lift north. Then front to lift
