This April, like most have delivered a taste of everything as you’d expect at this key transitional time of the year. Record cold, snow, heat, rain and big tornadoes have all featured but as you can see from the below temperature anomaly chart. Neutral to above normal temperatures have won out.

The month is winding up on a distinctly wintry note with Chicago under the gun of heavy snow for a a second weekend in a row and last of the month.

The official snowfall for Chicago¬†observed at O’Hare International Airport was 2.5 inches. This was the latest accumulating snow since 1989 (May 6).

Like we’ve seen so many times this month, another strong system is rolling west to east, seperating a big thermal contrast. As a result, the battle zone gets hammered with heavy, flooding rain, with severe weather to the south and east but on the cold north and northwest side, it’s heavy snow and temps 15-25 below normal.


The upcoming 7 days will see winter lead the N Rockies/Plains into May but summer for South and Southeast.

The cold looks to drift and expand south and east into week 2 and even 3 before a flip is likely to occur beyond May 20.
