NWS Forecaster Discussion




Area forecast discussion 
National Weather Service St Louis MO 
329 am CDT Wed may 27 2015 


Short term: (through late this afternoon) 
issued at 328 am CDT Wed may 27 2015 


Weak frontal boundary to slowly slide southeast through region 
today. Initial activity over northern portions of forecast area to 
exit before zone issuance. Next round firing up over southwestern MO 
and moving east northeast towards forecast area. Hrrr keeps activity 
along and south of I-70 this morning before diminishing. So highest 
pops will be over southern portions of forecast area. Otherwise, 
warm conditions to persist with highs in the low to mid 80s. 


Byrd 


Long term: (tonight through tuesday) 
issued at 328 am CDT Wed may 27 2015 


Weak ridging to build in tonight with precipitation tapering off. 
Did keep slights/low chance pops for southern portions of forecast 
area, but for the most part forecast area should be dry overnight. 
On Thursday, more vigorous shortwave to approach from the 
southwest. Will see increasing pops with best chances over central 
and southern Missouri during the day, then chances to increase 
beginning Thursday night as deepening upper level trof over The 
Rockies begins to slide towards region. Best chances will be 
Friday through Saturday, before tapering off on Sunday. 


Highs will be in the 80s for the rest of the work week with lows in 
the 60s. Cooler air to filter in behind this system with highs only 
in the upper 60s on Sunday, then warm back up into the upper 70s to 
low 80s by next Tuesday. 


Byrd

Aviation: (for the 06z tafs through 06z Wednesday night) 
issued at 1140 PM CDT Tue may 26 2015 


Isld/scttrd shras will continue to dot the area thru the prd. Weak 
forcing along a diffuse bndry will keep sporadic precip percolating. 
Current activity across cntrl/NE MO and W cntrl Illinois should slowly 
dsspt/move NE after 6z. Guidance hints at another batch of convection 
dvlpng across SW MO tonight. This precip, if it dvlps, will move 
NE but appears to remain south of the stl Metro terminals. Limited 
coverage precludes mention attm. Rain showers coverage may increase Wed aftn 
with the highest coverage expected to be east of the stl Metro. Winds 
will become wrly Wed mrng. 


Specifics for kstl: 


VFR fcst thru the prd though there will be isld/scttrd shras. A weak 
bndry will push thru the terminal drng the late mrng allwoing winds 
to become more wrly and taking the better chance of rain with it. 
Limited coverage precludes mention in the fcst attm.
