Any industrious gardeners who have already started on their summer planting may have some dead vegetation come Monday morning: The National Weather Service has issued a frost advisory for tonight for northeast Illinois and northwest Indiana.
The advisory, for 1 a.m. to 7 a.m. Monday morning, says temperatures could drop into the low to mid 30s tonight, and "sensitive plants left outdoors could be harmed." The record low for May 13 is 34 – and there's a good chance we'll get there.
Conditions will vary depending on where you live; those closest to the lake will be warmest. But at least it's better than the prediction for southwest Michigan, which has a freeze warning from 10 p.m. tonight until 8 a.m. Monday morning, with temperatures in the mid-to-low 20s. And it's the middle of May.
All of that will come after a chilly Mother's Day, which should feature some sunshine along with temperatures that will peak in the 50s. That'll make today the coldest Mother's Day since 2002, when the high was 50, according to ChicagoWeatherCenter.com.
But the spring weather roller coaster will start heading up again tomorrow, with predicted highs in the 60s for Monday and in the upper 80s for Tuesday and Wednesday.
