Weather Spring Begins Tuesday, What to Expect in Chicago – CBS Chicago


CHICAGO (CBS) – Although the vernal equinox isn’t until March 20, meteorologists and climatologists mark March 1 as the start of “weather spring.” This is when weather patterns begin to become more spring-like as temperatures begin to rise in the northern hemisphere.

The latest monthly outlook from NOAA’s Climate Prediction Center shows that March 2022 is an above average temperature month and also above average in terms of precipitation.

For temperatures in Chicago, the average high in March starts at 41 degrees on the first and then increases to 53 degrees on the 31st.

The average amount of snowfall is 5.5 inches in March in Chicago. Snowfall so far for the season stands at 28.6 inches, just 2.7 inches below average. The average rainfall for Chicago is 2.45 inches for March.

This March is likely to see more precipitation due to the impacts of La Niña, where below-average seawater temperatures along the equator in the Pacific Ocean allow for a more active jet stream for some parts of North America, including the Midwest.

Conclusion: The data suggests that we are heading for a milder and more humid climate over the next few months.

If we look at the snowfall averages for March and April, we are still expecting close to seven inches of snow. But as temperatures rise over the next few weeks, we’ll start talking less about the chance of snow and more about the chance of thunderstorms.

The clash of air masses (cold air in the north and warm, humid air in the south) can often not only create thunderclaps, but also the risk of severe weather.
