Another option would be to use the -file parameter on a switch statement. Using -file will read the file one line at a time, and you can use break to exit immediately without reading the rest of the file.

switch -file $someFile {
  # Parse current line for later matches.
  { $script:line = [DateTime]$_ } { }
  # If less than min date, keep looking.
  { $line -lt $minDate } { Write-Host "skipping: $line"; continue }
  # If greater than max date, stop checking.
  { $line -gt $maxDate } { Write-Host "stopping: $line"; break }
  # Otherwise, date is between min and max.
  default { Write-Host "match: $line" }
}
