Area forecast discussion...updated aviation 
National Weather Service St Louis MO 
1100 PM CDT Fri Aug 29 2014 


Short term: (through late tonight) 
issued at 354 PM CDT Fri Aug 29 2014 


Main focus through tonight will be on precipitation chances. Compact 
vort Max/mesoscale convective vortex will be main driver of precipitation through the period. 
Tied highest pops with track of this feature which current radar 
imagery supports as largest coverage of showers with embedded 
thunderstorms is just ahead of this feature through early this evening. 
Not sure how activity will evolve overnight...but do think that 
activity may become more scattered with loss of bulk of daytime 
instability and track of vort Max to the north of County Warning Area. Therefore... 
did lower pops back for late tonight. Associated frontal boundary will 
slowly ooze south and eastward overnight and begin to washout/stall out 
somewhere over the central portion of the County Warning Area bisecting from southwest to 
northeast. Temperatures will be seasonably warm...I.E. Upper 60s to low 
70s and did not deviate from guidance too much. 


Gosselin 


Long term: (saturday through next friday) 
issued at 354 PM CDT Fri Aug 29 2014 


Continuing with the short term theme of more scattered convection 
associated with this system...have lowered pops for Saturday morning 
across the entire area. 12z model guidance from this morning backed 
off precipitation chances and quantitative precipitation forecast for Saturday morning. The upper 
level trof will be flattening out and much of the vorticity will be 
moving off to the northeast of the area. Low level convergence will 
be fairly weak and with only weak low level warm advection ahead of 
the trof it looks like coverage will be limited. Expect though as 
the day heats up and the atmosphere becomes more unstable we'll see 
coverage increase. Have therefore kept likely pops for Saturday 
afternoon...generally along and east of the I-44/I-55 corridor. 
Should see storms diminish during the evening with the loss of 
daytime heating. 


Keeping with the slightly drier trend to the forecast, have lowered 
pops a bit on Sunday as weak shortwave ridging moves over the County warning forecast area 
in the wake of saturday's trof. With no obvious focus for surface 
convection showing up in the guidance, think the only real shot for 
convective initiation will be orographic effects from the Ozarks. 
Therefore have kept chance/slight chance pops along and south of the 
I-70 corridor Sunday assuming there will be scattered storms down 
there which will migrate northeastward. 


Little change to the forecast for next week...other than to bump up 
temperatures a little for Thursday and Friday. The next shortwave 
is still on track to dig into the Great Plains on Sunday 
evening...moving into the Midwest by Monday morning. While medium 
range guidance is in general agreement with the timing of the wave, 
the GFS shows a sharper/deeper wave while the European model (ecmwf) is less 
amplified. The surface front is still forecast to dip into central 
Missouri before stalling Monday night. The front remains over 
Missouri and southern Illinois on Tuesday providing a focus for 
convective development. Have kept likely pop Sunday night into 
Monday night as the front moves in and lingering chance pops 
continuing into midweek. As the front moves back to the north 
Thursday and Friday have lowered to slight chance and increased 
temps as the upper level ridge builds back across the central U.S.

Aviation: (for the 06z tafs through 06z Saturday night) 
issued at 1042 PM CDT Fri Aug 29 2014 


There were two areas of showers and storms this evening. The first 
was across southeast MO and will likely remain southeast of the 
taf sites late tonight, although they could get close to cps. 
There were scattered showers/storms across northwest MO ahead of 
an approaching upper level disturbance which may impact the uin 
area late tonight. May include thunderstorms in the vicinity in the uin taf. It appears 
that there will be enough cloud cover and strong enough surface 
winds to deter fog formation, although could not rule out light 
fog late tonight/early Saturday morning in sus and cps where the 
surface wind will be a little lighter and in areas which had 
significant rainfall this evening. Should be at least scattered 
showers/storms in the St Louis Metro area Saturday afternoon along 
and ahead of weakening cold front/surface trough dropping 
southeastward through the area. Sly surface winds will become 
more swly late tonight and Saturday morning. 


Specifics for kstl: current shower/storm activity on radar will 
likely miss stl late tonight, although could not rule out a 
passing sprinkle. Will likely leave stl taf dry late tonight and 
Saturday morning due to uncertainty in coverage and timing of 
additional convection. Will include thunderstorms in the vicinity in the taf Saturday 
afternoon with at least scattered showers/storms expected at this 
time due to diurnal destabilization along and ahead of a weak 
surface trough/cold front. Prevailing S-swly surface winds through 
the period.
