Scattered thunderstorms will continue to move east this morning, but more storms will develop later this afternoon. Some of those storms could become severe. High near 86* with a southeast wind at 10-25 mph. Tonight, thunderstorms with heavy rainfall possible. Low near 67* with a southeast wind at 5-15 mph. Storm chances continue through Saturday with severe weather possible as well. We'll dry out for the end of the weekend, but more storms are possible next week. Stay tuned for updates throughout the day on the severe weather potential.

Differences Between the new and old systems

• Wind speed is now calculated for 5 feet off the ground. Wind speed was previously based on observations at 33 feet.
• The calm wind threshold was lowered to 3mph.
• A consistent standard for skin tissue resistance is now in use.
• Measurements are based on how wind affects the human face, typically the most exposed portion of the body.
• The table incorporates the theory that heat is lost from the body depending on its surroundings
• The sun's impact is not factored into the wind chill temperature formula.
