AREA FORECAST DISCUSSION...UPDATED AVIATION

627 AM CDT Wed Jun 11 2014

.SHORT TERM:  (Through Tonight)
Issued at 105 AM CDT Wed Jun 11 2014

Not a lot of changes from the prev forecast thru the period. Mdls
are in good agreement system continuing to pull newd out of the
region into the Great Lakes area. Precip shud come to an end today
from W to E as the upper trof moves newd. Believe clouds will be
slower to break up and have trended temps slightly cooler than the
warmer MOS today. Trended twd the cooler guidance tonight as
clouds shud clear out thru most of the night before moving back
into the region late tonight across the wrn portions of the CWA.

.LONG TERM:  (Thursday through Tuesday)
Issued at 245 AM CDT Wed Jun 11 2014

Focus quickly turns to an approaching s/w and associated cdfnt on
Thursday. As the s/w crosses the Rockies, an MCS shud develop over
the Plains late tonight and move ewd. The main question will be
the track of the MCS that develops. Believe a more srn track is
more probable where higher instability is. However, with the sfc
fnt moving thru the region, the area shud destabilize enuf
allowing at least sct TSRA to develop. Have kept POPs in the
chance range for now.

Expect precip to be out of the region by Fri morning as sfc ridge
builds into the region. This ridge will leave the area dry and
bring cooler temps, remaining aob seasonal avg thru the weekend.

Mdls keep a sfc fnt in the region Sun thru the end of the forecast
period with a number of s/w moving thru the region. Kept likely
POPs for Sun thru the night as mdls suggested this forecast was
still on track. However, with uncertainty in fnt position and
timing of any given s/w, have kept POPs in the chance range for
Mon and beyond. With heights progd to rise early next week, have
trended temps warmer. Coverage of TSRA may have some impact on
temps. However, very little insolation shud allow temps to jump
quickly, especially with SW flow.

.AVIATION:  (For the 12z TAFs through 12z Thursday Morning)
Issued at 621 AM CDT Wed Jun 11 2014

Pesky upper-level low pressure system will finally begin to move
out of the region today with improving flight conditions. Low
ceilings are expected to rise to MVFR and then scatter out by
afternoon. Also a possibility of scattered showers redeveloping
late morning/early afternoon...but left mention out of TAFs for
now as better chance should reside over central
Illinois...east/northeast of terminals. Clear or mostly clear skies are
expected tonight with light winds as a surface ridge approaches.
Fog will likely become an issue...with KSUS being the most likely
candidate for IFR conditions.

Specifics for KSTL:

Pesky upper-level low pressure system will finally begin to move
out of the region today with improving flight conditions. Low
ceilings are expected to rise and then scatter out by afternoon.
Also a possibility of scattered showers redeveloping late
morning/early afternoon...but left mention out of TAF for now as
better chance should reside east of the Mississippi River. Clear
or mostly clear skies are expected tonight with light winds as a
surface ridge approaches. Some MVFR fog is probable due to moist
ground conditions.
