In the last 30 years how many April months have failed to see a 20C high?
In the last 30 years there have been 6 occasions where 20c wasn't reached until early May (1987, 2000, 2001, 2006, 2013, 2015). The latest of those was 10th May, with all the others being in the first 6 days of the month. In 2006 it was also the first 80f day of the year, as the high was 27.4c on 4th May. It has been recorded in March on 4 occasions.
The average absolute max for April is 22c, and a typical month sees 2-3 days above 20c.

Since 1981, for MDW average number of 68F/20C+ days is 8. Most was 13 on 1986, least was 1 in 1995. Interestingly since 1981, March actually had more days above 68F/20C+ in 2012 with 15 being recorded. In April 1955 MDW recorded 17 days at or above 68F/20C
April 2011 at Heathrow recorded 16 days above 20C with 5 days above 25C. That's probably our most interesting month since July 2006 warmth wise.
Looks like the days above 25C hovered around 26C with a peak of 27C?
Our spring temps (March/April) fluctuate much more dramatically than yours do. Even though your warmest April has a similar average max to our warmest (within a couple of degrees I think), the way we get there is much different.
MDW April 1986
7 days at or above 25C with 5 of them being at or above 27C, 2 above 30C, and an absolute max of 33C. We also had 4 days with high 9C or lower.... Yet the average high was 18.4C
NWS station nearest my house. I had 9 days at or above 25C, 7 days at or above 27C, 4 days at or above 29C, and also an absolute high of 33C. The monthly average was 19.8C. I'm 40 miles from the lake so little or no lake influence unlike MDW which is only 10 miles away and gets lake cooling.
Here is April 1955 across Chicagoland. Temperatures less variable and more consistently mild than in 1986

The Artukainen weather station which has been in operation since July 2010 is yet to see a 20C reading in April, probably because it's closer to the sea than the old airport station. The highest April reading is 19.5C. Maybe this year will be our year?
B87, irlinit, when does the trees start blossoming in London usually?
Still completely bare so far.
Mid July, usually.
Also, can we have a thread where it isn't full of Chicago related facts. Every bloody thread is "well my suburb, ORD and MDW are blah blah blah"
No disrespect to George, but it's just unnecessary.
