.DISCUSSION...

This afternoon, the cold front was located upstream and stretched
from central IN southwest across southern MO. This feature will drop
southeastward and move through our area by midnight. Airmass is
currently rather dry so no precipitation is expected, although
scattered high level cloudiness should continue.

On Wednesday, caa pattern will be in place. Will undercut guidance
by a degree or two and we should only see highs in the upper 40s to
near 50. The sfc ridge will stretch sw-ne and be in close proximity
for both Thursday and Friday mornings. At that time min temps will
be able to drop into the mid 20s to lower 30s range.

In the ext fcst, a southerly return flow will begin on Friday ahead
of the next dry frontal passage on Saturday. Slightly warmer both
days with highs 55 to 60. Not seeing much in the way of upper
ridging that could couple with the southerly flow to make it warmer.
It will again be a dry fropa as moisture depth is lacking.

Slightly better troughing behind the weekend fropa and so look for
below normal temps for early next week. Nothing all that cold but it
will be a few degrees below normal.

00Z TAF DISCUSSION.

A dry cold front will move across the area overnight, accompanied
by scattered to broken high and mid clouds, at or above 10k feet.
surface winds will be mainly below 10 kts overnight, with
northerly flow becoming a bit gusty during the daylight hours on
Wednesday.

Look for a brief period of MVFR ceilings early Wednesday morning
at CSV, mainly between 11z and 15z, as a slug of good 10000-850mb
moisture swings through.  Otherwise, expect VFR conditions to
prevail at area terminals through the forecast period.
