.WHAT HAS CHANGED...
No significant changes.

&&

.KEY MESSAGES...
1) High pressure and a somewhat cooler airmass will settle into the
area today into Saturday.

2) A series of upper level disturbances will result in occasional
rain chances through the first half of next week.

&&

.DISCUSSION...
KEY MESSAGE 1)
The cold front will move southeast of our area this morning with
high pressure building into the region behind it. This will lead to
dry and somewhat cooler conditions as we head into the weekend. Highs
today will range from the mid 60s north to the lower 70s in the
south, with highs on Saturday mainly in the 65 to 70 degree range.



KEY MESSAGE 2)
A mid level short wave will move out of the mid Mississippi Valley
Saturday night and across the Ohio Valley Sunday into Sunday night.
There remains some uncertainty as to how much moisture will be
pulled up into our area ahead of this, with the NAM and GFS still the
most bullish. However, the ECMWF/ECMWF mean have trended just a bit
wetter, so will continue with chance pops.

A deeper mid/upper level trough is forecast to progress east across
the central CONUS early next week, but there remains significant
differences in the timing of this as well as the timing/placement/
strength of any embedded short waves. As a result, a fair bit of
uncertainty continues with the forecast through the second half of
the long term period so will still broad brush with chance pops.

&&

.AVIATION /03Z FRIDAY THROUGH TUESDAY/...
A cold front will continue to move southeast across the area early
this morning, with some VFR stratocumulus persisting in its wake
through mid morning. With high pressure and a drier airmass building
to the region behind the front, VFR conditions will prevail through
the remainder of the TAF period. North winds to around 10 knots can
be expected today with winds then decreasing as they become more
northeast to east tonight.

OUTLOOK...MVFR ceilings and visibility possible Sunday into Monday.
