NOAA station: Chicago Midway AP · 4.1 mi away · 612 ft elevation · est. first 1" snow: Nov 15.

The reference station for Cicero is Chicago Midway AP (4.1 mi, 612 ft). First freeze there: 32°F by Oct 31, 28°F by Nov 11, 24°F by Nov 20. That hard freeze has landed anywhere from Oct 31 to Nov 26, a swing of roughly 26 days. Spring's last 32°F freeze clears around Apr 11. Snowfall averages 39 inches a year, first reaching an inch near November.

The freeze arrives in two steps in Cicero: 32°F around Oct 31, then a hard 28°F near Nov 11. That first freezing night has ranged from Oct 20 to Nov 14, roughly a 25-day spread. On the spring side, the last 32°F freeze clears around Apr 11 and as late as Apr 27 — the green light for reopening water and de-winterizing. With around 39 inches of snow annually, plan for a handful of plowable storms each winter.

Your snow blower checklist

  1. Change the oil and check the level; cold-thickened old oil makes the engine harder to pull over.
  2. Drain summer-old fuel and refill with fresh gasoline, then add stabilizer so it stays good through the season.
    Helpful gear: Fuel stabilizer — Recommended pick
  3. Inspect the spark plug and swap it if the tip is dark or worn; a fresh plug is a cheap no-start fix.
    Helpful gear: Replacement spark plug — Recommended pick
  4. Check the shear pins and keep spares on hand — they break on purpose to protect the auger gearbox.
    Helpful gear: Shear pin kit — Recommended pick
  5. Set the tire pressure to the 15–20 psi range printed on the sidewall so the machine tracks straight.
  6. Lubricate the auger and chute controls and confirm the chute rotates and tilts freely.
  7. Do a test start now, well before the first storm, so any repair happens before the shop lines form.
  8. Keep a good shovel by the door for steps and for the day the machine still will not cooperate.
    Helpful gear: Backup snow shovel — Recommended pick

What this means locally

Cicero freezes close to Berwyn (Nov 15) and close to Oak Park (Nov 15) — a reminder that even nearby towns differ by days. Statewide, Illinois prep dates run Oct 25 through Nov 24, which is why Cicero gets its own number rather than a Illinois-wide average. The same freeze also decides when to keep your roof edge clear and protect your pipes.

Frequently asked questions

When should I get my snow blower serviced?
Service the machine about three weeks before the first plowable snow, which here is estimated near Nov 15 from NOAA snowfall normals. Servicing early means fresh fuel, oil, a good plug, and spare shear pins are in place before repair shops fill up after the first storm.
How old can gas be in a snow blower?
Untreated gasoline can start to break down in about 30 days, gumming the carburetor and making the engine hard to start. Use fresh fuel and add stabilizer if it will sit, or run the tank dry at the end of the season. Ethanol-blend fuel is especially prone to trouble in small engines.
Why won't my snow blower start after summer?
The usual culprit is stale fuel that varnished the carburetor over the off-season. A fouled spark plug, old oil, or a clogged fuel line can also be to blame. Draining old gas, fitting a fresh plug, and adding clean, stabilized fuel solves most first-storm no-starts.
What are shear pins and how many spares do I need?
Shear pins are small bolts that connect the auger to its shaft and are designed to break if the auger hits something solid, protecting the gearbox. Keep at least two to four spares and the right size for your model, since a broken pin in mid-storm stops the machine until you replace it.
Electric vs gas snow blower for Cicero?
Electric and battery machines are quiet, low-maintenance, and fine for lighter, shallower snow and smaller drives. Gas machines handle deep, heavy, wet snow and long driveways better. Match the choice to your typical snowfall and driveway length; heavier-snow areas usually favor gas.
How many inches of snow before using a snow blower?
Most single-stage blowers work best on about two inches or more; below that a shovel or broom is faster. Two-stage machines handle deeper accumulations. Clearing in stages during a big storm, rather than waiting for it to finish, keeps the load on the machine manageable.
