We have a winner. Here is the question again.  What is the best tornado detector?  The winner is Diane Foushee. She was the first person to post the correct answer – the human eye. Yes, the human eye is still the best tool we have in finding tornadoes. Radar can find many, but most of the tornado warnings are generated because someone saw it and contacted the authorities. I’ll have another weekly weather quiz question for you next Monday. The first person to post the correct answer will win one week of free personalized forecasts tailored to your needs.

A trough of low pressure (shaded area that’s “U” shaped over the southwest)  is moving to the east and spreading south and high pressure is moving in after it. A weak frontal system (out of  the Gulf of Alaska) will be coming through Saturday will raise our temperatures to more comfortable levels. As the low pressure moves out high pressure behind it will give us another brighter and warmer period, but the weekend won’t be perfect.  The next storm system will be moving in late Sunday to Monday bringing with it more precipitation. Does this weather pattern sound familiar? At least most of the sunshine has been occurring over the weekend when a lot of people want to play or putter around outdoors.
