While just shy of record-setting, we logged another unseasonably mild late November day with highs near 70. Temperatures remain mild well into tomorrow before a cold front slices through the region, with a period of showers, heavy in spots. Cooler weather filters in for Tuesday night and beyond.
Through Tonight: It won’t feel at all like November. Temperatures only slowly fall from their near-70 degree peak. Except well to the southwest, showers likely hold off until after sunrise. Under cloudy skies, overnight lows range from the low-to-mid 50s in the cooler suburbs to the upper 50s downtown.
Tuesday: Showers develop from southwest to northeast between sunrise and midday. They move through over the course of several hours, with skies brightening - particularly to the southwest by mid-to-late afternoon. Rain may continue into the P.M. commute in the eastern suburbs. The rain may briefly fall heavily, with amounts generally around 0.5”, with locally higher amounts up to an inch or so. Temperatures are generally steady, with highs in the low 60s.
Tuesday night update: In my forecast from this morning, I mentioned the possibility of some light rain, possibly mixed with sleet and snow in the colder north and west suburbs (especially high spots) late Tuesday night. Latest guidance tracks the upper level low (same one bringing snow to the South) far enough west that I think we miss the bulk of this precipitation (chance of precip down to 20%).
