It was incredibly warm Tuesday night-Wednesday morning with lows not even dropping below 70 for a good chunk of the area. Our WLFI ob site only dropped to 72 degrees. The Purdue Airport only dropped to 73. Lows tended to be 64-69 north & 69-73 south.
The low for April 28 in the Greater Lafayette records will go down as 66.
This does break the record low for the date of 65 set in 1974, 1914 & 1899.

Main rainfall will occur the rest of tonight & then tapering to just some occasional showers in the morning. Lows will run in the 50s with a couple bands of 1.5-3" (some isolated +3" amounts) rainfall over the area with lesser amounts in-between these two main bands.
It should end completely by afternoon with some sunshine developing.
With north-northwest winds to 32 mph, it should turn out to be a decent day with highs 61-68 north to south (67 Greater Lafayette).
A couple isolated showers are possible in the evening-early night as a secondary cold front & short wave pivot through.
Lows by Friday morning should run 42-47.
Highs Friday should reach 61-70 north to south (67 Greater Lafayette) with mostly sunny skies (but more clouds northeast). Northwest winds of 20-37 mph are expected.
Weekend looks good with 76-81 Saturday & 80-85 Sunday with sunshine & strong southerly winds gusting to 37 mph.
Saturday morning should be in the 40s & Sunday morning in the 50s.
Multiple rounds of showers & storms are likely Monday-Wednesday of next week.
Highs should run in the 70s to 80s.
Locally-heavy rainfall of +2" in possible & some severe weather risk may creep in.
The trend has been for Wednesday to be our best potential of severe weather, but data tonight suggests that it may very well be Monday-Monday night with SLIGHT RISK & even ENHANCED RISK parameters over the area.
Tuesday &/or Wednesday may end up featuring more with MARGINAL RISK parameters, it appears.
After a dry Thursday (highs near 68-72), looks like an Alberta Clipper system may pass Friday (highs 70s) with a few showers & storms & gusty southwest, then northwest to north winds.
May 8 & 9 look cooler with "Black Locust Winter". Highs of 61-68 are expected with lows 37-42.
After that brief stint at cooler weather, we should rebound rapidly & 80s should move back in very quickly. Severe weather should line up from Manitoba to Texas around May 9-10.
We may get some storms in here around May 11 with MARGINAL RISK parameters showing up, owing to lack of good, robust instability (despite being in the 80s).
It is far out, so we will continue to monitor.
The May 15-23 period looks particularly active with multiple rounds of storms with locally-heavy rainfall & basically severe weather risk in the area every other day or two. Highs in the 80s are expected.
After a brief cool-down with dry weather around May 24-27, we should heat up May 28-31 with 90s possible & largely dry weather.
All of the severe weather outbreaks will be confined way, way north to Saskatchewan, Manitoba, Montana, the Dakotas, Nebraska & Minnesota. It is a good pattern to get some big tornadic, large hail-producing storms in eastern Montana & into the Canadian Prairies.
It looks like severe weather risk may get back into our area by June 3 with the hot weather.
