Air Conditioner or Furnace? From 80s to Frost!

That's the debate in the Chambers household these days, and I doubt we're the only ones!

Let's do a quick review of our recent rollercoaster ride. High temperatures averaged 78 degrees from Monday through Friday of last week. Factored into that number were our first two 80-degree-plus days of the year (Wednesday, April 23 at 81 and Friday, April 25 at 80). A cold front swept across the bi-state area Friday, bringing a round of strong to severe thunderstorms, and also bringing a shot of cooler air. Highs Saturday were only in the mid 60s. And then, Mother Nature kicked us when we were down. Another front rolled through Missouri and Illinois Sunday -- more clouds, a few passing showers, and another shot of cool air -- highs only in the upper 50s.

And today? Yep, another front, another chance of showers, and another reinforcing shot of unseasonably cool air! That's a total of three fronts in fairly quick succession since Friday. Behind front #3, temperatures will struggle to climb into the lower 50s today.

If you think that's cool, read on! You ain't seen nothin' yet.

Frost advisories and freeze warnings have been posted for eastern Missouri and western Illinois from midnight to 9:00 AM Tuesday. Clear skies, light winds, and dry air will send the mercury dropping, and fast! By 6:00 or 7:00 AM Tuesday, temperatures will range from the upper 20s to lower 30s across most of our area. Now that we're in the midst of the growing season, you might want to cover your outdoor plants to protect them from the frost, and even the potential of a hard freeze, before you go to bed tonight.

So, are you under a frost advisory or a freeze warning? And, what's the difference anyway? Get the answers to these questions and more by checking out the very latest warnings and advisories.
