No significant changes.

&&

.KEY MESSAGES...

.DISCUSSION...
KEY MESSAGE 1)

Update...
Additional showers and thunderstorms - scattered in coverage are
expected to develop this aftn associated with another impulse
moving into Indiana. With scattered coverage, some local heavy rain
remains possible but the widespread heavy rain threat has
diminished, Therefore, the flood watch has been allowed to expire.

Previous...
Thunderstorms developing in association with another
impulse across Illinois and Missouri will move across the area this
afternoon. This will also be in conjunctions with a pre-frontal
trough. Precipitable water will still be high, but the warm cloud
layer will not be quite as deep. So there may still be locally heavy
rain, but the flooding threat appears to be more isolated. In
addition, with moderate instability there could be some more robust
storms that could produce strong to damaging winds.

KEY MESSAGE 2)
Low amplitude short wave will push a cold front into the area
tonight. This will become elongated in a north northeast to south
southwest orientation which will cause the boundary to be slow to
move all of the way through the region. There will still be some
potential for showers and storms until this front clears.

Broad long wave trough will move into the Great Lakes towards mid
week. This will push another cold front through late Wednesday into
Wednesday night. There will be a bigger change in air mass with highs
will be in the 70s with lows in the 50s to lower 60s for the latter
part of the week.
