The weather is forecast to improve in Chicago in time for the annual St. Patrick's Day parade on Saturday.

People gathering during the early morning along the streets and bridges to watch the 2018 parade on Saturday, March 17, will have to contend with chilly conditions and perhaps a light wintry mix of rain, sleet and wet snow. Watch for slippery spots on the roads and the sidewalks early Saturday.

However, the storm projected to produce the wintry mix is also expected to weaken and move to the south during the midday and afternoon hours.

As a result, some sunshine should emerge just before or during the parade.

Temperatures will start the day near the freezing mark (32 F) and climb past 40 during the afternoon. How quickly this occurs will depend on how fast clouds break.

A light breeze will produce AccuWeather RealFeel® Temperatures from 5 to 10 degrees lower than the actual temperatures, and any sunshine during the afternoon will negate some of that chill.

As has been the case since 1962, the Chicago River will be dyed green.

However, this year a bit more of the river will be dyed, according to the Chicago Tribune. A longer parade route, compared to prior years, is also in store to help accommodate more spectators.

St. Patrick's Day is dear to the hearts of those of Irish heritage, but for many this day is a reminder that spring is really just around the corner.

Spring officially begins on Tuesday, March 20, at 11:15 a.m. CDT.
