Hopefully everyone has a great Memorial Day!  Remember the true reason for the holiday, and we are thankful for all of those who gave their lives for this country so we can celebrate our freedoms.  It's looking like a fantastic day for outdoor activities... we'll have plenty of sunshine and temperatures will be in the 70's during the afternoon.  Unfortunately, as we look ahead to the rest of the week, we'll have more chances for rain and thunderstorms.  Let's begin!

The Storm Prediction Center in Norman, Oklahoma has placed NW PA under a slight risk for severe weather on Tuesday afternoon and evening.  The main risks with these storms will be strong, damaging wind gusts and large hail.  The tornado risk is low, but still there. 

As the next low pressure system moves up from the southwest, it'll allow for the atmosphere to destabilize and bring thunderstorms along with it.  We'll have to watch this situation carefully.  As a low pressure center sits right over NW PA, the right conditions come together in the right locations to cause thunderstorms that produce large hail.  Also, storms that interact with the warm front (shown as the red arrow in the image below) have the chance to start rotating, which is why there's still a small tornado risk with these storms.

Rain chances will still hang around on Wednesday and Thursday, but things will definitely clear up on Friday as another cold front rolls through and causes all of the bad weather to exit the area.  You can almost think of a cold front as a "reset button", as it usually resets our weather to sunny skies and pleasant conditions!

Enjoy the week, and as always, follow us on Facebook and Twitter for the latest weather updates.
