Surface high pressure migrates east across the mid to upper Ohio
River valley tonight-tmrw. Some weak warm air advection returns,
mainly in the semo Ozarks, around the high's backside, with small
rain chances Wednesday.

Afterwards, upper ridging/heights rising leads to a more robust
warmup as high pressure to the east pumps warm southerlys across
the mid MS/lower Ohio Valley. Temps will return to Summer like 80s
by this weekend, with lows and dew points likewise climbing back
to more Summer like humidity levels in the 60s.

This will all occur ahead of a developing front that will approach
Saturday, and then sweep into the region with high chance Cat pops
from Sat night-Sun night. After this system's passage, we cool
back to seasonal temps for early next week.

Drier air is taking awhile to work down the column, but will
ultimately make it, probably scouring out most MVFR cigs by or
even before this evening. Winds diminish overnight and with
clearing skies, patchy fog may develop late tonight. Gridded time
height cross sections show some return moisture moving in from the
west tmrw morning, but precip chances should refrain from mention
in the terminals, best chance being kcgi if they do occur.
