Thursday evening forecast May 20
A low pressure system over northern, California will bring cooling through Saturday. This system will also bring a slight potential of mountain showers. Strong west to northwest winds will remain through Friday, with the strongest conditions along southern Santa Barbara County. A weak ridge will prompt some warming from Sunday into Monday, before cooling right back down.
Winds are the main concern as we end the work week. A Wind Advisory over the Central Coast will expire today at 9 PM. While a Wind Advisory remains in effect across southern Santa Barbara coastal and mountain areas until Friday morning. North to northwest winds will range between 25 to 35, with gusts up to 50 mph. The strongest winds could be expected between Gaviota and Refugio as well as the hills above Montecitio.
The system will sink further south into Friday, prompting more morning fog and clouds. A second impulse will rotate along southern, California by Saturday morning. Some moisture along with instability could bring a slight chance of light showers over mountain areas. Otherwise conditions staying relatively dry and clear by the afternoon.
The upper low will shift east into Monday, with a weak ridge developing right behind it. Onshore flow will remain very light Monday, with warmer air along the west coast. This will allow skies to clear quicker, with about 3 to 6 degrees of warming from Saturday.
Another weak system will swing through our area from Tuesday through Thursday, prompting a stronger marine layer and cooler temperatures.
