Chilliest Mother’s Day in more than a decade

Despite ample sunshine, temperatures  on Sunday should climb only into the lower and middle 50s making this the city’s chilliest Mother’s Day since 2002 when the high reached just 50 degrees.  With clearing skies and light winds expected Sunday night, temperatures are expected to approach the record low of 34 degrees  Monday morning with frost possible in areas away from the lake.  Warmer air approaches Monday as temperatures rebound into the lower 60s, but arrives in earnest Tuesday and Wednesday as temperatures surge to the highest levels of the year reaching the upper 80s Tuesday and approaching 90 on Wednesday.  Some thunderstorms could develop Monday night, but the best chances for precipitation arrive ahead of a cold front late Wednesday or Wednesday night.
