One rule about forecasting spring weather here is: don't declare the freeze season over until you have a good reason to be absolutely certain (and no, Easter Sunday has no correlation with spring freezes).
We are right at the time when we have, on average, our last freezing temperature (32º) of the spring season. Rarely does it occur on the average date of March 21, though. The past two years our last freezes happened on March 26, 2014 and March 27, 2013. In 2007 the area had a widespread frost on April 8 (though not "officially" in the city of Columbus). But in the mild spring of 2012, we didn't have a freeze after February 13. The latest ever in Columbus was in 1953, on April 21. This year, March 7 (31º) stands as our latest freeze to date.
However, it may not wind up as the last. Recent model runs are indicating that a strong cold front is due in here around the end of the week, one that will bring a significant shot of cold air deep into the South. Parts of Georgia and Alabama seem to be almost certain to have a freeze Saturday and/or Sunday mornings, but will it reach as far south as central Georgia? That is an open question at this point, and we will be keeping a close eye all week on this potentially frosty scenario for next weekend. The map is from the GFS model run, with the white line representing the freezing line from the model for next Sunday morning very close to Columbus.
In the near term, we're dealing with cool temperatures and rain. This weekend's rain system should be gone by Monday afternoon, leaving us with a pleasant Tuesday and probably Wednesday. Another chance of showers will return Thursday and Friday as a pair of cold fronts slide through, with the cold air to follow on Friday and Saturday, bringing a bit of spring chill for a couple days.
Meanwhile, our very quiet severe weather season continues, with no sign of the kinds of energetic storm systems that spawn spring tornadoes in the Southeast. But to follow up on what I've said in recent posts, the pattern could still evolve into a later than usual tornado season. We have both warm, moist air and cold, dry air in the picture and a shifting upper air pattern in transition from the cold to warm season, so don't be surprised if things get a lot more active in April.
