WHAT TO KNOW

  • Spectacular Saturday

    • Today is pleasant and mostly sunny with highs near 70-degrees

  • Showers Sunday

    • Mostly cloudy skies are expected with light showers at times in the afternoon.

THIS WEEKEND

It's a gorgeous start to the weekend. A few clouds move in this afternoon with highs near 70-degrees and a breeze from the northeast at 10 mph. No jackets needed today, but grab the sunglasses

Dinnertime temperatures drop into the mid 60s with clear skies overnight. Overnight lows are in the low to mid 50s.

Sunday is mostly cloudy with the best chance for dry weather in the morning. Spotty light showers are possible early, but will be more widespread in the afternoon. Heavy rain is not expected and it's not enough rain to worry about plans canceling. However, it's a good idea to keep an umbrella handy or a rain jacket.

NEXT WEEK

Ample sunshine returns for Monday and temperatures are mild to start. A cold front drops temperatures for Tuesday and Wednesday. The morning will be cold, in the 40s. The afternoon is mild with highs only around 60-degrees.

There's a potential warm up into the 70s on the way for the end of the week and next weekend, but for now we will keep 60s in the forecast as there is still some uncertainty about how warm it will get.
