BREAK, THEN SQUALL LINE POSSIBLE TUESDAY……
1. New data is in good agreement that our front is speeding up & will pass through on Tuesday, not Wednesday. This has been a trend over the past 30 hours in the analysis.
2. Still look like a lull with some sunshine Tuesday afternoon.
3. Squall line is possible late in the day. Directional shear is more pronounced with this squall line, so will have to watch isolated tornado threat. Otherwise, main threat damaging straight-line winds.

RIVER FLOODING LIKELY……………
1. Given rainfall of 1.5”-3” likely total through Tuesday, river flooding is likely, especially on the Wabash River.

2. Those 50s look to occur next Saturday & Sunday with rain potential Sunday.
