MCV over west central Missouri will continue to lift northward this
morning with activity associated with it sliding north through
region. Coverage is scattered and will see precipitation taper off
from southwest to northeast today. Because of a bit more cloud cover
and precipitation, highs will only be in the upper 70s to low 80s.

.AVIATION:  (For the 12z TAFs through 12z Wednesday Morning)
Issued at 701 AM CDT Tue May 26 2015

Showers and isolated thunderstorms are expected to move out of the
terminals by 14Z this morning. MVFR ceilings have recently
redeveloped across Missouri and may linger past 15Z. Expect these
ceilings to lift by late morning and expect mainly dry and VFR
conditions through the rest of the TAF period. Only exception will
be up at KUIN where that terminal will be close enough to a
frontal boundary later this evening that it may see a
thunderstorm when an upper level storm system moves over the area.
MVFR/possibly IFR conditions in moderate-heavy rain would be
possible with any thunderstorms.

Specifics for KSTL: Ceilings have varied low MVFR and VFR during
the night and they are currently around 2000 feet. Expect them to
stay MVFR through 14Z with improvements in the ceilings by late
morning. Otherwise, expect the rest of the TAF period to be mostly
dry and VFR.
