Light and variable winds early this morning, quickly becoming southwesterly and gradually increasing in speed to around 10 mph by noon with gusts around 20 mph. Winds become west to northwesterly this afternoon, strengthening to 10-15 mph sustained and gusting to around 25 mph. Mostly sunny skies this morning, then scattered showers and thunderstorms are expected to develop this afternoon. Exact timing of the showers/storms is tricky due to the scattered nature that is expected, but the most likely timing is 1 PM to 9 PM. In this time window, expect on-and-off showers and storms mixed with periods of sunshine. There is a 5% chance that some of these storms could be strong to severe, capable of producing hail up to quarter size and wind gusts up to 60 mph. With passing showers and storms this afternoon, expect occasional gusty and erratic winds. While the current forecast rain amount is less than a tenth of an inch, it is certainly possible that there could be higher amounts approaching around a quarter to half an inch if storms track right over the site. A brief break in rain is possible tonight, but additional light rain showers are expected to redevelop tonight and linger into Thursday. Thunder is not expected with these showers. Winds will remain gusty from the northwest going into Thursday. .TODAY... Sky/weather.........Mostly sunny (30-40 percent).
