AccuWeather's Memorial Day Weekend Forecast: Caution is Advised

As you plan for the weekend, here is AccuWeather's forecast:

Where it says "strong storms," more detail is needed. For that we turn to the NWS SPC.
Above is an important map. It is the probability of severe thunderstorms (large hail and damaging thunderstorm winds) and tornadoes between 7am Saturday and 7am Sunday. The significant probability threshold is 15% on this chart. The hatching is where very large hail, extreme winds and violent tornadoes are possible. Therefore, I urge you to take along a portable NOAA weather radio plus the new AccuWeather app (and turn on the GPS function).
