We're making our move from heavy coats to shorts and t'shirts this week. Of course, this only applies to the daytime hours. Tonight does drop to 42°. Tomorrow's a bit warmer, though, getting to 63°. We'll keep on chugging until we get to the 70s on Sunday.
No need for an umbrella until next week. We may get a few spits of rain, at best, from Friday through Monday.
