Fortunately [datetime] structs have a DayOfWeek property we can use to check that!

Simply advance the date by 1 day at a time until you reach Wednesday:

function Get-UpcomingWednesdayAt5
{
  param(
    [datetime]$Date
  )

  while($Date.DayOfWeek -ne [System.DayOfWeek]::Wednesday){
    # advance 1 day at a time until its wednesday
    $Date = $Date.AddDays(1)
  }

  # Create new [datetime] object with same Date but Time set to 5AM
  return Get-Date -Date $Date -Hour 5 
}
