Weather 

A front moved thru this morning that gave us around a quarter inch of rain. The front is followed by the associated low pressure area that weakened but will continue to trigger some showers around the area. The winds tonight easterly 4-8, the low near 55.

The low continues to move east of the area tomorrow as a trough of low pressure also moves across, then the shower activity becomes more widely scattered in the afternoon as conditions improve.  Winds tomorrow becoming northwesterly 4-8, the high temperature near 66. With high pressure building in, tomorrow night looks partly cloudy and with calm winds, the low drops to near 49.

Friday, we see mostly sunny skies, winds becoming northerly 5-10, the high up near 70, then mostly clear skies Friday night, lows near 54.

The weekend is looking pretty nice, Saturday looks sunny with the high temperature climbing to up near 75, with the mostly clear skies Saturday night, the lows near 52. Then Sunday, the ridge weakens some, so we see mostly sunny skies with the high back down to near 70.  We do see a few clouds Sunday night so partly cloudy skies, the low near 51.

Monday, little changes, mostly sunny skies expected though model agreement starts to decline, the high still up near 71, add some patchy fog Monday night, lows near 52. Tuesday there will be more clouds, so we see partly sunny skies, and with less sun, the high near 69.

The long range models suggest cooler temperatures later next week, and possibly another weather system by the end of next week. We will see!

National Preparedness Month

As I watch Hurricane Ian moving across Florida, I am reminded that with some of the Pacific Storms, hurricane force winds can be seen offshore and into the coastal regions. So, I thought it would be good to review some of the National Weather Service Watches and Warning related to Winter Wind events.
