Today is the best day of the week weather-wise. But tomorrow won't be terrible. There is a likelihood of some showers/thunderstorm, but it will remain dry for most of the day. Friday won't be too shabby either. Unfortunately the weekend looks wetter now than it did a couple of days ago.
A boundary or battle zone of cool air to the north and summer like heat to the south will be fought over our heads. This means showers and thunderstorms are likely Saturday and Sunday. The bad news: it's Mother's Day. The good news: It will be dry most of the time.
Look at the bright side: Remember how April felt like March: cold and nasty. Well, at least the weather agrees with calendar. It feels like May. Even thunderstorms are normal for May.
So get out and enjoy it!
