Localized flooding a concern; storms could be severe
After off-and-on showers during the early evening, with a few heavy downpours mixed in, a more solid batch of rain is enveloping the metro area from west to east. Rain will be heavy at times tonight, with thunderstorms possible as well. Watch out for localized areas of flooding. Any thunderstorms that do develop have the potential to produce damaging winds. With a good amount of spin in the atmosphere, the chance of a tornado can't be ruled out, either.
It probably won't be until after midnight that the rain begins to exit the area from west to east. By morning, any lingering showers and clouds should quickly give way to a mostly sunny and breezy Wednesday with highs in the mid 50s. Diminishing winds tomorrow night with mostly clear skies and lows in the low to mid 30s in the burbs, mid to upper 30s downtown.
Stay tuned for updates should any severe warnings be issued.
