- Only a chance of a widely scattered thunderstorm Sunday night into early Monday
- Highs 60's today, approaching 70 Saturday, near 80 Sunday, and into the 80's Monday through the middle of next week

In Your Outdoor Weekend Activities, Make Sure to...
So, the usual safety issues for your outdoor weekend plans will be:
- make sure your campfires are completely put out.
- watch for some cold water in streams and lakes up north
- have some protection from potential rain, especially Friday night and Saturday.
- make sure to watch the number of hours you are out in the sun Sunday and Monday and use plenty of sun block (many of us could go from white skin directly to red if we overexpose)
Remember Why We Celebrate Memorial Day
And, take a bit of time to honor the sacrifice of those who have served our country.
