Now that we’ve gotten the general idea nailed down, we can jump into specific details. As you can see, this is a relatively long-duration storm. This loop runs for 48 hours from 7pm Wednesday to 7pm Friday. Here’s a visual description of the evolution of the storm: Here’s a loop of our winter storm through its duration, courtesy of the 00z Thursday run of the HRRR. The overall impacts from this storm will be the highest during this timeframe. Round 2, from Thursday afternoon through Friday morning, will be the main phase of the storm that will feature the heaviest precipitation. Through Thursday morning, precipitation across the region will remain light until a second, stronger shortwave arrives on Thursday afternoon. As our front slides south, changeovers from rain to frozen precipitation will occur from northwest to southeast. Round 1 will bring light to moderate precipitation, and actually most regions should just see plain rain. The first shortwave, arriving late Wednesday evening, will bring the first round of precipitation. As the frontal system slows to crawl, two primary shortwaves will move through our region, bringing unsettled weather with them. An advancing frontal system will slide east on Wednesday, acting as a highway for shortwaves to ride on. The second precipitation shield over the South Central US will be responsible for the main round of precipitation Thursday evening through Friday.Ĭompared to the set up of last weekend’s nor’easter/blizzard, this setup is much simpler.
