.SHORT TERM:  (Through Late This Afternoon)
Issued at 233 AM CDT Fri Jul 18 2014

Upper level low continues to move slowly east across the CWA with
rain being confined to extreme southern Missouri. Have maintained
some slight chance POPs for today across the far south, but
generally expect a clearing trend from the northwest as the upper
level low moves east into the Ohio River Valley. Have maintained
previous forecast highs in the upper 70s and lower 80s.


.LONG TERM:  (Tonight through Thursday)
Issued at 233 AM CDT Fri Jul 18 2014

Weather pattern to transition from one dominated by a TROF across
the eastern CONUS to one dominated by a building ridge across the
Rockies, Plains and Midwest. Summer weather returns this next week
with temperatures climbing to or above average next week. Rain
chances look to remain limited to the middle of next week when model
guidance depict a shortwave topping the upper level ridge across the
upper Midwest and moving it east into the southern Great Lakes. This
could bring a back door cold front into the CWA and a chance of
thunderstorms. For now kept POPs at chance category as ensemble
guidance is far less excited about the southern extent of any
shortwave/cold front intrusion.



.AVIATION:  (For the 06z TAFs through 06z Friday Night)
Issued at 1138 PM CDT Thu Jul 17 2014

VFR flight conditions and light east-southeast flow will continue
to prevail across the area.

Specifics for KSTL:

VFR flight conditions and light east-southeast flow will continue
to prevail at Lambert.
