SEVERE POTENTIAL TUESDAY (See Above)

CLUSTER OF RAIN/STORMS TONIGHT…..
1. Heavy rain & hail potential exists tonight as cluster of rain/storms passes & lasts into Sunday morning.

BREAK, THEN SQUALL LINE POSSIBLE SUNDAY………
1. Still looks like a lull with some sunshine on Sunday afternoon.
2. Squall line is possible late in the day with main threat being damaging winds between 4 p.m.-11 p.m. (LARGE WINDOW DUE TO DISAGREEMENT ON TIMING OF THE LINE).

CLUSTER OF RAIN/STORMS MONDAY NIGHT…….
1. Cluster of heavy rain/hail possible Monday night with complex that passes through.

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.

COLD SNAP INTERRUPTED BY 2 MILD DAYS………
1. Thankfully 2 days of 50s will be sandwhiched in our cold snap.
2. Those 50s look to occur next Saturday & Sunday with rain potential Sunday.
3. Otherwise, highs March 11-17 will be 35-40.
