Two bands of 1-3" & isolated +3" rainfall amounts occurred in the viewing area over the past 36 hours, but the soils soaked it up well!
1.59" our WLFI ob site was the heaviest rainfall event since March 18.
A couple to few isolated showers & even a t'shower or two are possible tonight with partly to mostly cloudy skies.
Lows will run 44-52 with a northwest breeze.
Friday looks mostly sunny & windy with highs 62-70 north to south. Northwest winds will turn to the north with gusts 30-40 mph.
Given the cold Lake Michigan water, that strong fetch of a north wind will lead to lake breeze front rushing inland. So, highs will tend to occur near midday in the far north & early to mid-afternoon farther south. The chilling effects of the lake may reach as far south as Romney & Burlington later in the day.
Along & north of that line, temperatures should fall to 55-64 in the afternoon.
After clear skies Friday night, high clouds will increase with arrive of warm front. After lows 40-46, we should see 78-84 Saturday with south-southwest winds sustained at 20-30 mph with gusts 35-45 mph.

Round of showers/storms are possible Monday morning, followed by a break with sunshine, rapid warming & south-southwest winds to 37 mph.
Then, storms should develop in eastern Iowa, southern Wisconsin to western Illinois to Missouri in the afternoon. These supercells will merge into line & race eastward.
They should pass through our area Monday evening-early night with SLIGHT RISK parameters in place. ENHANCED RISK parameters show up just south of our area. We will monitor.
After highs 78-84 Monday with dew points 65-70, we should drop to 55-62 Monday night with some showers.

Alberta Clipper system may pivot through Friday with a few showers & storms. If the steep lapse rates with the cold pocket aloft are realized, then some hail risk may develop. With gusty southwest winds, 70s are possible Friday.
A wave of rain & storms is possible likely around May 11 after drier & cooler trend for a bit.
More active regime with rain & storms is likely in the around May 15-23 period.
