DISCUSSION
Issued at 215 AM EDT Thu Apr 9 2026
- Light rain today
Low pressure center moves across James Bay today with a trailing cold front bringing light rain this morning. The front clears Lower Michigan this afternoon with sfc ridging bringing clearing skies by evening. The front stalls across IN/OH then returns late Thursday.
- Rain Thursday night Friday
A wave of low pressure along the stalled front spreads rain back into Lower Michigan Thursday night into Friday. Strong moisture advection and some elevated instability suggest embedded convection is possible, which could lead to locally higher QPF approaching an inch across central and southern zones before the rain ends Friday afternoon.
- Excessive rainfall potential next week
Monday through Thursday of next week appears to hold the potential for more flooding rains as Plains lows track into the Great Lakes. This is similar to the synoptic pattern last week that brought flooding and could also result in severe weather depending on details that cannot be resolved yet.
AVIATION /06Z TAFS THROUGH 06Z FRIDAY/

MARINE
Issued at 215 AM EDT Thu Apr 9 2026
No changes to the Gale Warning and SCA. Winds should go northwest and diminish Thursday afternoon. Winds and waves should be relatively clam into the weekend then ramp up again as southerly winds increase on Sunday.
HYDROLOGY
Issued at 215 AM EDT Thu Apr 9 2026
Rain amounts today are expected to be light enough not to affect river levels or contribute to flooding of low lying areas. More significant rain is expected on Thursday night into Friday with over half an inch forecast for much of the Grand and Kalamazoo River basins. This could cause minor rises on those rivers or more likely the their tributaries through the weekend.
