  • The National Weather Service in Rapid City has issued a Winter Storm Warning for Custer, Fall river, Oglala Lakota, Jackson and Bennett County. This bulletin is for areas of heavy snowfall, where accumulations could exceed 6+” of snow in many areas.
  • A Winter Weather Advisory has also been issued for Rapid City in Pennington County, along with Southern Campbell and Weston County in Wyoming for snow accumulations of several inches being possible.

  • A sharp accumulation drop-off is expected somewhere along the I-90 corridor, this is where confidence is low as to final snow totals.
  • This is expected to be a heavier, wet snow – particularly near the Nebraska border. Take your time shoveling and give yourself frequent breaks if need be.

FORECAST DISCUSSION

Thankfully, winds don’t look to play a major factor in this storm system, but snow ratios will make pinpointing exact accumulations a little difficult. Overall, this is much needed moisture – this is a well forecasted storm, so make sure you’re taking the necessary precautions!

Stay safe out there.
