- Rain chances Wednesday then turning cooler

Moisture increases in southerly flow through Wednesday with height falls as upper low approaches, but chances for rain remain low through Tuesday. The better chance for measurable rain is not until Wednesday and even then it looks like heavy rain is unlikely with convection remaining south of the forecast area and dry slotting occurring rather quickly.

Wraparound, lake-enhanced showers, along with cooler temperatures can be expected through the end of the week as upper troughing remains and is eventually reloaded this weekend by a vigorous northern stream shortwave trough. Current slight chance POPs for the weekend may eventually trend higher given decent ensemble support got the timing and location of this trough.

MVFR ceilings below 2,000 ft are overspreading southwest into central Michigan this afternoon and evening. JXN is already IFR, and while it may have temporary improvement to MVFR this afternoon, the trend at most locations will be for ceilings to lower and probably dip into IFR between 00 and 07 Z. LLWS is likely between 07 and 14 Z, becoming gusty after 14 Z with some improvement to ceilings.
