The Ugly Truth
Mother Nature pulled the rug out from under our spring/early-summer weather, and nothing exemplifies that more than the following two figures ... the high temperature map from yesterday and the 24-hr temperature change map from today:

So when you have 24-hour temperature drops of more than 30-40 degrees from the 80s and 90s, you have to hope it is during July or August. Of course, today would have been considered a nice day through parts of February and March. But after the previous week's worth of spring-tease, it's just pouring salt in bitter winter wounds.
To make matters worse, we have freeze and frost warnings in effect for much of western and central Oklahoma tonight:

Now a freeze this late is nothing extraordinary, as we can see from our average date of last freeze map (based on 1971-2000 data):

And before I complain too loudly, I should remember how bad it could be:

Temperature drops like this are the epitome of our transitions months here in Oklahoma, so we'll just wait a few days for the nice weather to return. Just be sure and remember to bring in your tender plants, animals and climatologists (those last two are redundant) tonight and everything should be fine.
