Area Forecast Discussion National Weather Service Northern Indiana 1113 AM EDT Thu May 22 2025
KEY MESSAGES
- Skies slowly clearing through the afternoon.
- Most, if not all of the upcoming Memorial Day weekend appears to be dry with a few showers possible by Monday afternoon.
- While temperatures into early next week will remain below normal, they will slowly increase by a few degrees each day and return to normal levels by mid week.
UPDATE
Issued at 1101 AM EDT Thu May 22 2025
Light rain/drizzle was quickly trending downward with the greatest concentration across NW Ohio. Vis satellite already showing thinning or partial clearing of clouds working in from the NW so some areas should see at least some sunshine through the afternoon. Have adjusted pops and sky cover based on the current trends. No changes to temps but will see how they respond with the clearing, especially NW with a better chance to seize some of the peak heating.
DISCUSSION
Issued at 331 AM EDT Thu May 22 2025
Broad cyclonic flow remains in place over the Great Lakes. Numerous showers are ongoing early this morning as excellent Pacific moisture advection is noted on water vapor. This moisture stream contracts later today, undercut by incoming high pressure currently digging in over the Upper Peninsula. Time height cross sections show a strong push of subsidence arriving this afternoon which will allow showers to cease from northwest to southeast. A few peeks of sun are possible late, but not guaranteed in this stagnant pattern. Across southern Michigan tonight, very cold for late-May especially if clouds clear. The inherited forecast lows were a touch warm area- wide, so I did nudge lows down resulting in a low of 39 near Hillsdale. Northwest wind near 10 mph should minimize any frost concerns.
While drying out Friday and into the first part of the weekend, cool northwest flow prevails resulting in continued below-normal temperatures. Discrepancies remain beyond Sunday night with respect to an incoming Colorado low. Strong high pressure centered over the Great Lakes ought to suppress this low to our south, especially amid a rather zonal 500-mb pattern across the southern US. In the meantime, I've retained some 20-30% POPs for Memorial Day through Tuesday. It is by Tuesday through late week that an upper-level low could take shape over the eastern Great Lakes bringing more showers.

Issued at 1101 AM EDT Thu May 22 2025
