Rain Chances Start Friday

Today's Forecast

Today's Forecast Image
  • 71°
  • 44°

After a breezy but delightful day Thursday, the winds of change are blowing.  The first in a series of upper level disturbances will arrive Friday, kicking off a week of shower and thunderstorm chances.  While it won't be raining all the time, keep an umbrella handy if you have outdoor plans over the Memorial Day weekend.  While the severe weather threat isn't great, isolated storms could become severe over the next week...another reason to stay weather-aware.

Mostly clear skies will be seen early Friday morning, and lows will fall to the mid-40s.  We'll start off on a dry note after sunrise with partly cloudy skies, but by afternoon and evening we have a chance for showers and thunderstorms.  Highs will reach the lower 70s.

Along with our daily shower and thunderstorm chances over the next week, we'll see highs warming into the 80s.  While isolated severe weather is possible, the overall severe storm threat is not particularly high.

Be ready for severe weather by downloading our free weather App for your iPad, iPhone, or Android.
