Main concern for today is that we will have to watch for a very low (5-10%) chance of a shower or thunderstorm in the area that could produce some gusty and erratic winds for a brief period between 1400 and 1900 this afternoon. After a quiet and calm overnight period, we will have a better chance (60%) for some showers and thunderstorms around during the day on Friday, some of which may contain gusty winds and hail. .REST OF TODAY...
