NWS Forecaster Discussion




Area forecast discussion...updated aviation 
National Weather Service St Louis MO 
640 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.

Aviation: (for the 12z tafs through 12z Thursday morning) 
issued at 640 am CDT Wed may 27 2015 


Recent radar trends are showing showers moving up toward kcps and 
just south of ksus/kstl. Went ahead and added tempo groups for 
MVFR conditions in -shra through 14z at kcps, and added vcsh at 
ksus/kstl. Expect this area of showers and thunderstorms to move 
out of the area by mid morning leaving the rest of the taf period 
dry with VFR conditions. Winds will turn light and variable at 
most of the terminals tonight. 


Specifics for kstl: the terminal will lie on the northern periphery 
of a large area of showers and thunderstorms through 14z. Have 
added just vcsh for now with just VFR conditions, but may need to 
amend to add -shra if showers move farther northward than 
expected. Otherwise expect dry and VFR conditions the rest of the 
taf period.
