Are you superstitious? Do you walk on egg shells on Friday the 13th? What about during full moons? How would you feel if both were to fall on the same night?
Even though it's the middle of May, there is a good chance of seeing some snow tonight. It shouldn't be enough to shovel, but still, any snow in May sucks.
Did you get outside today in the warm sunshine? If the wind wasn't blowing it would've been a perfect early spring day. It was nice, but how long with it last?
Usually, if the temperatures only fluctuate a little bit, it's hard to tell. It's still not Spring-like, But it feels warmer than it did the last few days.
