Rain, cold snap predicted, but officials don’t think showers will trigger more flooding

Monday’s balmy spring weather won’t last for long, as temperatures dip back below average Tuesday with a cold snap expected to hit the area mid-week.

The mercury rose to the low 60s Monday — with inland areas flirting with the average high of 62. But Tuesday it’s back to the 50s and approximately three-quarters of an inch of rain. Showers are expected to hit the West and Northwest suburbs shortly after 1 a.m. Tuesday morning, while the rest of the area will see rainfall start between 4 a.m. and 7 a.m.

Fresh rains aren’t expected to trigger more flooding, but for those hit hardest by last-week’s flooding it may delay the drying-out process and the receding of river water levels, said Richard Castro, a meteorologist with the National Weather Service.

“We’re not looking at anything like last week, but considering how wet it is and how saturated the soil is, having any rain at this point is probably not a good thing,” Castro said.

Rain showers will vary in intensity Tuesday, he said, contributing to an “overall gloomy day, cloudy with highs in the mid-50s.”

Then comes the cold.

Temps on Wednesday and Thursday will barely reach 50, as a fast-moving cold front moves in and brings some quick rain showers Wednesday night that could mix with snow.

“It looks like a brief, two-day cold snap for this type of year,” Castro said. “It’s a couple days of unseasonably chilly temps.”

Tuesday through Thursday will see lows at night top out in the 30s.

The average daytime high for this time of year is in the lower 60s, and Castro said we’ll be closer to hitting that mark as the weekend approaches.

“It looks like we’ll have a chilly start to the day on Friday, but much nicer than the two days previous. Saturday and Sunday look like we’ll warm up to the sixties,” he said.
