Iowa Storm Center has issued a Winter Storm Watch for northwest, north central, northeast, west central, central, southwest and south central Iowa. Read on for the details...

Date: 1/16/23 at 11:25am Central

Timing: Effective later Wednesday through Thursday....

Discussion: A strong Pacific storm will move out of the southwest overnight on Tuesday and into the entire watch area through Wednesday. The thought line right now is wintry mix works into southwest Iowa by daybreak Wednesday with snow working into western Iowa late morning through the afternoon and into the evening. Central Iowa may start with a heavy rain before changing over to a wet snow. Heavy snowfall rates will be likely in the deformation band with moderate to heavy snow accumulations and amounts of up to 12" in localized areas. In the earlier stages of the event, a wintry mix will coincide from west central to southwest Iowa where light ice accumulations will also be possible. Then snow would taper off from west to east by later Thursday morning. In addition, wind gusts of 20-35 MPH will be likely Wednesday through Thursday which may lead to blowing of snow, especially in rural locations. We are still early so snowfall amounts will be updated Wednesday morning for you, but if you are in the watch zone, prepare for moderate to high snowfall accumulation numbers.

Threats -

  • Heavy Snow Rates
  • Wintry Mix west central to southwest Iowa
