March weather forecast
Illinois, USA

March heralds the onset of spring in Illinois, bringing with it a gradual alleviation of winter’s icy hold. In the northern parts, closer to Wisconsin, temperatures start to show signs of moderation, with daytime readings often rising to the mid-40s°F (around 44.6°F (7°C)). The southern reaches, near the Kentucky border, experience a warmer transition, frequently registering temperatures in the upper 40s°F to low 50s°F.

Chicago, being a prominent urban center, starts to observe an easing in its lake effect snow occurrences. While March can still bring occasional snow showers to the city, they become less frequent and intense as the month progresses. The melting snow, combined with seasonal rains, can occasionally lead to wetter conditions in the region.

Nighttime temperatures in March, though still chilly, don't plummet as drastically as the preceding months. It's not uncommon for lows to be in the 30s°F (around 33.8°F (1°C) to 39.2°F (4°C)) statewide. The snow cover that once blanketed the state starts to recede, especially in the southern areas. By the end of March, most of the state sees diminishing snow depths, with only sporadic patches in shaded or northern areas.

Comparatively, March is noticeably milder than February. The increase in sunlight hours and the sun's higher position in the sky catalyze the transition from winter to spring. As March concludes, the environment readies itself for the warmer and more temperate conditions that April promises to bring.
