The original version didn't have groundhogs as it was predicting western European weather, it was attached to Candlemas day. And that's one of the festivals that were adopted from the preChristian pagans.
If Candlemas Day be fair and bright Winter will have another fight If Candlemas Day brings cloud and rain Winter won't come again
Which means that if we're under an anticyclone the weather will stay clear and cold, but if we're getting a succession of Atlantic lows they'll continue to bring in warmer, wet air off the ocean.
It is also one of the mid-seasonal days - half-way between solstice and equinox - as you said, adopted from pre-Christian observances. The others are May 1 - May Day or Imbolc, Aug 1 - Midsummer or Lammas, Nov 1 - All Saint's Day or Samhain.
According to wikipedia: Imbolc (or St. Brigid's Day) was traditionally a time of weather divination, and the old tradition of watching to see if serpents or badgers came from their winter dens may be a forerunner of the North American Groundhog Day.
